The genes that enhance reproduction, often by making an animal or plant more adapted to the environment, thus come to predominate in populations. For example, the ancestor of the polar bear was brown, but when it came to occupy snowy areas, genes for white color were favored, as they camouflaged the bears from their prey, giving white bears a greater ability to get food\u2014and hence leave more offspring than did brown bears. Over time, this form of natural selection genetically transformed the color of the species from brown to white.<\/p>\n<p class=\"whiteParagraph\">All that is required for natural selection is that there is variation among the forms of genes (i.e., different \u201calleles,\u201d like those producing brown versus blue eyes in humans, or our different blood types), and that some genes promote enhanced reproduction of their carriers than do alternative forms of those genes. The variant forms of genes arise by the process of mutation, which is \u201crandom\u201d in the sense that errors in the genetic material occur regardless of whether they are useful. But then a deterministic process\u2014natural selection\u2014takes over and winnows out the bad variants, preserving the good. In general, this kind of change improves the adaptation of organisms to their environment, explaining why plants and animals are remarkably suited to their habitat.<\/p>\n<p class=\"whiteParagraph\">Natural selection is often called \u201csurvival of the fittest\u201d, but this is a misnomer in two ways. First, what is important is reproduction: carriers of some genes leave more copies of those genes, in their offspring, than do carriers of others. Survival is important only if it leads to greater reproduction. (Genes that kill organisms after they\u2019ve stopped reproducing are not detrimental.) Second, natural selection does not produce absolute perfection, but only individuals better adapted than those of previous generations. Mutations making an animal perfectly adapted to its environment may simply not be possible. (If perfection were possible, species would not go extinct, for they\u2019d be able to withstand any assault by the environment.)<\/p>\n<p class=\"whiteParagraph\">Thus, a better characterization of natural selection would be \u201creproduction of the fitter.\u201d<\/p>\n<p class=\"whiteParagraph\">Finally, although natural selection is often described as a \u201cforce\u201d or \u201cagent\u201d acting on organisms, that\u2019s just shorthand for what is really happening: not some external force changing a species directly, but simply a process of differential sorting of genes that often depends on the environment in which those genes are expressed.<\/p><\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t\t<div class=\"elementor-toggle-item\">\n\t\t\t\t\t<div id=\"elementor-tab-title-2042\" class=\"elementor-tab-title\" data-tab=\"2\" role=\"button\" aria-controls=\"elementor-tab-content-2042\" aria-expanded=\"false\">\n\t\t\t\t\t\t\t\t\t\t\t\t<span class=\"elementor-toggle-icon elementor-toggle-icon-left\" aria-hidden=\"true\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<span class=\"elementor-toggle-icon-closed\"><i class=\"fas fa-caret-right\"><\/i><\/span>\n\t\t\t\t\t\t\t\t<span class=\"elementor-toggle-icon-opened\"><i class=\"elementor-toggle-icon-opened fas fa-caret-up\"><\/i><\/span>\n\t\t\t\t\t\t\t\t\t\t\t\t\t<\/span>\n\t\t\t\t\t\t\t\t\t\t\t\t<a class=\"elementor-toggle-title\" tabindex=\"0\">What is Species and Speciation?<\/a>\n\t\t\t\t\t<\/div>\n\n\t\t\t\t\t<div id=\"elementor-tab-content-2042\" class=\"elementor-tab-content elementor-clearfix\" data-tab=\"2\" role=\"region\" aria-labelledby=\"elementor-tab-title-2042\"><p class=\"whiteParagraph\">One of the most obvious observations about nature is that it is divided into discrete units. When we look at a bird, for instance, we can immediately identify it as a cardinal, a sparrow, a pigeon, a starling, and so on. These groups are not arbitrary, so that birds do not form an avian continuum in which individuals blur together insensibly. And so it is with nearly every group of animals and plants. These objectively distinct groups are called \u201cspecies.\u201d<\/p>\n<p class=\"whiteParagraph\">To evolutionary biologists, a \u201cspecies\u201d consists of a group of organisms that can mate and produce offspring with each other, but are separated from members of other species by \u201creproductive isolating barriers\u201d: those biological features that prevent different species from producing fertile offspring. The barriers are diverse, including those factors that adapt species to different environments, so that they never meet (e.g., polar bears vs. brown bears); those factors that affect the likelihood of mating, so that members of different species either attain reproductive condition at different times (e.g., different coral species) or simply do not find each other acceptable as mates (e.g., many insect species); and those factors that impair the viability or fertility of hybrids (e.g., the sterile mule, a hybrid between a donkey and a horse). All of these factors prevent genes from moving between different species and thus keep the spcies distinct.<\/p>\n<p class=\"whiteParagraph\">The process of \u201cspeciation\u201d occurs when one ancestral species branches into two or more reproductively isolated species. This usually occurs when a single species has populations that are separated by geographic barriers like oceans or mountain ranges. By preventing mating between populations of a species, these geographic barriers allow the populations to evolve independently, along different genetic pathways. If these pathways diverge to such an extent that the populations have evolved nearly complete reproductive barriers, then speciation has occurred. In other words, the geographic barriers, by allowing independent evolution, promote the evolution of the reproductive barriers. This process of repeated branching of lineages explains the \u201ctree of life\u201d: how, starting with one ancestral species about 3.7 billion years ago, we now have millions of branches: the living and extinct species.<\/p>\n<p class=\"whiteParagraph\">\u00a0<\/p><\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t\t<div class=\"elementor-toggle-item\">\n\t\t\t\t\t<div id=\"elementor-tab-title-2043\" class=\"elementor-tab-title\" data-tab=\"3\" role=\"button\" aria-controls=\"elementor-tab-content-2043\" aria-expanded=\"false\">\n\t\t\t\t\t\t\t\t\t\t\t\t<span class=\"elementor-toggle-icon elementor-toggle-icon-left\" aria-hidden=\"true\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<span class=\"elementor-toggle-icon-closed\"><i class=\"fas fa-caret-right\"><\/i><\/span>\n\t\t\t\t\t\t\t\t<span class=\"elementor-toggle-icon-opened\"><i class=\"elementor-toggle-icon-opened fas fa-caret-up\"><\/i><\/span>\n\t\t\t\t\t\t\t\t\t\t\t\t\t<\/span>\n\t\t\t\t\t\t\t\t\t\t\t\t<a class=\"elementor-toggle-title\" tabindex=\"0\">What is Natural Selection?

If females have preferences for certain characteristics of males (in animals, it\u2019s almost always females who choose males rather than the other way round), then males with those characteristics will leave more offspring than males without them, and so the population will evolve males with the attractive traits. In peacocks, for example, females prefer males with showier tail feathers and more \u201ceyespots\u201d on their feathers. Over time, this led to the evolution of males with the long, extravagant, and beautiful tails we so admire.<\/p>\n<p class=\"whiteParagraph\">But this process can actually reduce the survival of males: male peacocks, weighted down by those tails, are not as good at flying or escaping predators as peacocks with shorter tails. But what is important in natural selection is reproduction, not just survival, and the mating advantage of long-tailed males more than compensates for their survival disadvantage.<\/p>\n<p class=\"whiteParagraph\">Two other points. First, sexual selection, first proposed by Darwin in 1871, is the explanation for why, if one sex is showier than the other, or has brighter colors, louder calls, or fancier plumage, that sex is almost invariably the males. Many experiments have supported this idea. Second some mysteries remain: why do female peacocks, for example, prefer longer tails in males, and female house finches brighter colors in males? In some cases, as in the armaments of males like the longer tusks of male elephants, the larger body size of elephant seals, or the big jaws of stag beetles, we do have the answer: males need these weapons to fight for females. But an explanation for traits like bright male color or long male plumage still eludes us, and scientists are working on these problems now.<\/p>\n<p class=\"whiteParagraph\">\u00a0<\/p><\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t\t<div class=\"elementor-toggle-item\">\n\t\t\t\t\t<div id=\"elementor-tab-title-2044\" class=\"elementor-tab-title\" data-tab=\"4\" role=\"button\" aria-controls=\"elementor-tab-content-2044\" aria-expanded=\"false\">\n\t\t\t\t\t\t\t\t\t\t\t\t<span class=\"elementor-toggle-icon elementor-toggle-icon-left\" aria-hidden=\"true\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<span class=\"elementor-toggle-icon-closed\"><i class=\"fas fa-caret-right\"><\/i><\/span>\n\t\t\t\t\t\t\t\t<span class=\"elementor-toggle-icon-opened\"><i class=\"elementor-toggle-icon-opened fas fa-caret-up\"><\/i><\/span>\n\t\t\t\t\t\t\t\t\t\t\t\t\t<\/span>\n\t\t\t\t\t\t\t\t\t\t\t\t<a class=\"elementor-toggle-title\" tabindex=\"0\">What is meant when people refer to a \"missing link\"?<\/a>\n\t\t\t\t\t<\/div>\n\n\t\t\t\t\t<div id=\"elementor-tab-content-2044\" class=\"elementor-tab-content elementor-clearfix\" data-tab=\"4\" role=\"region\" aria-labelledby=\"elementor-tab-title-2044\"><p class=\"whiteParagraph\">Opponents of evolution often say that we have no \u201cmissing links\u201d between species showing that they had a common ancestor, so that evolution could not have occurred. But this claim isn\u2019t really true. A \u201cmissing\u201d link between two groups would represent a single fossil species that itself was the ancestor of two existing groups (i.e., of modern humans and modern chimpanzees); and finding a single species in the fossil record is very difficult: far less than 1% of all species that ever lived are known as fossils. But you can demonstrate common ancestry in an easier way: the existence of \u201ctransitional forms\u201d that are on the line between a common ancestor and their modern descendants. So, if we go back in time through the fossils, we should find species resembling the common ancestor more and more.<\/p>\n<p class=\"whiteParagraph\">And indeed, we have many examples of such transitional forms: early birds that resemble their theropod dinosaur ancestors, but with feathers. We have early horses that have four toes, which gradually disappear as horses fossils come closer and closer in time to the present day. Likewise, we have transitional forms between fish and amphibians, between amphibians and reptiles, between reptiles and mammals, and between modern humans and their more apelike ancestors. There are hundreds of these examples, decisively proving the idea of common ancestry. Further, the transitional forms occur in the right time in the fossil record.

In science, a \u201ctheory\u201d is a coherent explanation for a diverse set of observations, an explanation that accounts for all the observations. For instance, we still refer to the \u201ctheory of gravity\u201d or \u201cthe atomic theory\u201d or \u201cthe germ theory of disease,\u201d yet each of these are well supported explanations for why objects fall the way they do, why matter behaves in certain ways, and why infectious disease involves viruses, protozoans, and bacteria.<\/p>\n<p class=\"whiteParagraph\">Although evolution is often dismissed as \u201conly a theory,\u201d it is in fact as well supported as are the \u201ctheories\u201d of gravity, atoms, and disease-causing microbes. (Nobody doubts, for instance, that smallpox is caused by a virus or that the formula for water is H 2 O.) There are literally thousands of observations that support evolution, and no observations that refute it. (There could have been such observations: for example, the discovery of mammalian fossils in 400- million-year old layers of the fossil record. But this kind of data simply hasn\u2019t been seen.) And the observations that support evolution come from diverse areas of science: paleontology, embryology, morphology, the fossil record, molecular biology, biogeography, and so on. This gives us strong confidence that evolution is true.<\/p>\n<p class=\"whiteParagraph\">Although no scientific theory can ever be proven correct\u2014it\u2019s always possible that some remarkable observations that haven\u2019t yet been made could disprove evolution\u2014evolution is about as certain to be true as any theory can be. The fact that, after 150 years, no observations have disproven it gives us confidence that the theory of evolution really is true. You could confidently bet your life savings on that!<\/p><\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t\t<div class=\"elementor-toggle-item\">\n\t\t\t\t\t<div id=\"elementor-tab-title-2047\" class=\"elementor-tab-title\" data-tab=\"7\" role=\"button\" aria-controls=\"elementor-tab-content-2047\" aria-expanded=\"false\">\n\t\t\t\t\t\t\t\t\t\t\t\t<span class=\"elementor-toggle-icon elementor-toggle-icon-left\" aria-hidden=\"true\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<span class=\"elementor-toggle-icon-closed\"><i class=\"fas fa-caret-right\"><\/i><\/span>\n\t\t\t\t\t\t\t\t<span class=\"elementor-toggle-icon-opened\"><i class=\"elementor-toggle-icon-opened fas fa-caret-up\"><\/i><\/span>\n\t\t\t\t\t\t\t\t\t\t\t\t\t<\/span>\n\t\t\t\t\t\t\t\t\t\t\t\t<a class=\"elementor-toggle-title\" tabindex=\"0\">Are all species related?<\/a>\n\t\t\t\t\t<\/div>\n\n\t\t\t\t\t<div id=\"elementor-tab-content-2047\" class=\"elementor-tab-content elementor-clearfix\" data-tab=\"7\" role=\"region\" aria-labelledby=\"elementor-tab-title-2047\"><p class=\"whiteParagraph\">The answer is a firm \u201cyes\u201d! Molecular data show unequivocally that all living species descended from a single species, called the \u201cLast Universal Common Ancestor\u201d that probably lived about 3.8 billion years ago. That single species then branched again and again, giving rise to not only the millions of species living today, but to the millions of species that went extinct without leaving descendants.<\/p>\n<p class=\"whiteParagraph\">The relatedness of all species is shown not only through similarities and differences in their DNA, but in the retention of ancestral traits in some descendants, like the muscles that enable some humans to wiggle their ears: a nonfunctional remnant of the muscles that moved the ears of our mammalian ancestors in an adaptive way\u2014to localize sound.

We\u2019re not the endproduct of our lineage, of course, for Homo sapiens, like all species, continues to evolve. Both fossil and molecular evidence show that our common ancestor with our closest relatives (the two species of chimpanzees) lived 6-7 million years ago. We diverged from our next closest relative, the gorilla, via a common ancestor that lived about 9 million years ago.<\/p>\n<p class=\"whiteParagraph\">In the past six million years, at least a dozen different species of \u201chominins\u201d evolved \u2014those species that sprouted from \u201cour\u201d branch that diverged from chimps\u2014with perhaps three or four of them living at the same time, and perhaps in the same place! (Neandertals and \u201cmodern\u201d humans are two of these; and some of them actually interbred.) Imagine these members of different human-like species encountering each other for the first time! Many of these species simply went extinct without leaving descendants, while others continued on the lineage that gave rise to us. We\u2019re still not clear about the precise species on that lineage, but paleontologists and molecular biologists are constantly revising and clarifying the story of human evolution.<\/p><\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t\t<div class=\"elementor-toggle-item\">\n\t\t\t\t\t<div id=\"elementor-tab-title-2049\" class=\"elementor-tab-title\" data-tab=\"9\" role=\"button\" aria-controls=\"elementor-tab-content-2049\" aria-expanded=\"false\">\n\t\t\t\t\t\t\t\t\t\t\t\t<span class=\"elementor-toggle-icon elementor-toggle-icon-left\" aria-hidden=\"true\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<span class=\"elementor-toggle-icon-closed\"><i class=\"fas fa-caret-right\"><\/i><\/span>\n\t\t\t\t\t\t\t\t<span class=\"elementor-toggle-icon-opened\"><i class=\"elementor-toggle-icon-opened fas fa-caret-up\"><\/i><\/span>\n\t\t\t\t\t\t\t\t\t\t\t\t\t<\/span>\n\t\t\t\t\t\t\t\t\t\t\t\t<a class=\"elementor-toggle-title\" tabindex=\"0\">A final word on Charles Darwin:<\/a>\n\t\t\t\t\t<\/div>\n\n\t\t\t\t\t<div id=\"elementor-tab-content-2049\" class=\"elementor-tab-content elementor-clearfix\" data-tab=\"9\" role=\"region\" aria-labelledby=\"elementor-tab-title-2049\"><p class=\"whiteParagraph\">Born in 1809, Charles Darwin was only 22 years old when was named the companion of the captain of the HMS Beagle, a ship appointed by the British government to survey the coast of South America. It turned out that the voyage lasted five years, giving Darwin, an amateur naturalist, a chance to observe and collect plant, animal, and rock specimens from around the world.<\/p>\n<p class=\"whiteParagraph\">After the Beagle returned to England in 1836, Darwin began pondering all these observations, and slowly realized that organisms were not created all at once and had been unchanged ever since\u2014the \u201ccreationist\u201d view of virtually all scientists of the time\u2014but had evolved gradually over millions of years. Scrutinizing his data also led him to see that organisms hadn\u2019t just changed over time, but that their lineages had split repeatedly, leading to the appearance of new species and to the branching bush of life. This, in turn, implied that all species had common ancestors. Finally, after pondering the remarkable ability of humans to create new varieties of plants and animals by controlled breeding (\u201cartificial selection\u201d), Darwin hit on his most novel idea: natural selection\u2014the process explaining the remarkable adaptations of plants and animals to their environments. (See \u201cWhat is natural selection?\u201d)<\/p>\n<p class=\"whiteParagraph\">The development of Darwin\u2019s theory was very slow, for he worked it out over decades not only through careful thinking, but through corresponding with hundreds of people around the world and discussing his ideas with his colleagues. Finally, in 1859, he put it all together in a single world-changing book: On the Origin of Species by Means of Natural Selection, usually called simply The Origin. His ideas and the data he gave supporting them were so convincing that within a decade virtually every thinking person in Europe and the United States accepted evolution as true.The concepts of evolution and natural selection have been called \u201cthe best ideas anybody ever had\u201d, for they not only changed our view of nature, but also of our own place in nature and our evolutionary origin from earlier species and relatedness to all living species. Scientific work since 1859 has shown Darwin\u2019s major ideas to be correct, and so, in this single book, he laid out the true story of not just human origins, but the origins of every creature, living and extinct. No other biologist has ever changed our understanding of nature as much as Darwin. That is why he\u2019s considered a hero to many scientists.<\/p>\n<p class=\"whiteParagraph\">Here is the stirring last paragraph of The Origin:<\/p>\n<blockquote>\u201cThus, from the war of nature, from famine and death, the most exalted object which we are capable of conceiving, namely, the production of the higher animals, directly follows. There is grandeur in this view of life, with its several powers, having been originally breathed into a few forms or into one; and that, whilst this planet has gone cycling on according to the fixed law of gravity, from so simple a beginning endless forms most beautiful and most wonderful have been, and are being, evolved.\u201d\u00a0<br \/><br \/><em>\u2015\u00a0Charles Darwin,\u00a0The Origin

hard-wired in our biology through genes or other inheritance. A new study suggests that the fear of spiders and snakes has been shaped by evolution, stretching back to a time when early man slept on the ground or in caves and had to survive in an environment dominated by arthropods and reptiles.<br \/>\nCertain stimuli are pre-wired in the brain because they have been perennially dangerous to our ancestors. Although some of us fear snakes more than others, baby humans, chimps and monkeys are equally jumpy when confronted with a black plastic snake. That aversion probably grew out of pressures of life in the jungles and savannas of Africa eons ago. Back then, encounters with poisonous snakes or spiders were a matter of life or death, and a healthy fear of snakes helped our ancestors live long enough to procreate.<\/p>\n\t\t<\/div>\n\t\t\t\t<\/article>\n\t\t\t\t<article class=\"elementor-post elementor-grid-item post-239 post type-post status-publish format-standard hentry category-evolution\" role=\"listitem\">\n\t\t\t\t<div class=\"elementor-post__text\">\n\t\t\t\t<h2 class=\"elementor-post__title\">\n\t\t\t<a href=\"https:\/\/nowthatswild.com\/new\/earths-entire-history-on-a-football-field\/\" >\n\t\t\t\tEarth&#8217;s Entire History On A Football Field\t\t\t<\/a>\n\t\t<\/h2>\n\t\t<div class=\"elementor-post__content\"><style>.elementor-239 .elementor-element.elementor-element-6f79134 .elementor-wrapper{--video-aspect-ratio:1.77777;}<\/style>\t\t<div data-elementor-type=\"wp-post\" data-elementor-id=\"239\" class=\"elementor elementor-239\" data-elementor-post-type=\"post\">\n\t\t\t\t\t\t<section class=\"elementor-section elementor-top-section elementor-element elementor-element-a0302cf elementor-section-boxed elementor-section-height-default elementor-section-height-default\" data-id=\"a0302cf\" data-element_type=\"section\" data-e-type=\"section\">\n\t\t\t\t\t\t<div class=\"elementor-container elementor-column-gap-default\">\n\t\t\t\t\t<div class=\"elementor-column elementor-col-100 elementor-top-column elementor-element elementor-element-6887d31\" data-id=\"6887d31\" data-element_type=\"column\" data-e-type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t<div class=\"elementor-element elementor-element-6f79134 elementor-widget elementor-widget-video\" data-id=\"6f79134\" data-element_type=\"widget\" data-e-type=\"widget\" data-settings=\"{&quot;youtube_url&quot;:&quot;https:\\\/\\\/youtu.be\\\/M8V_glRW1hA&quot;,&quot;video_type&quot;:&quot;youtube&quot;,&quot;controls&quot;:&quot;yes&quot;}\" data-widget_type=\"video.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<div class=\"elementor-wrapper elementor-open-inline\">\n\t\t\t<div class=\"elementor-video\"><\/div>\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<\/div>\n\t\t<\/div>\t\t<\/div>\n\t\t\t\t<\/article>\n\t\t\t\t<article class=\"elementor-post elementor-grid-item post-243 post type-post status-publish format-standard hentry category-evolution\" role=\"listitem\">\n\t\t\t\t<div class=\"elementor-post__text\">\n\t\t\t\t<h2 class=\"elementor-post__title\">\n\t\t\t<a href=\"https:\/\/nowthatswild.com\/new\/ginkgo-a-living-fossil\/\" >\n\t\t\t\tGinkgo: A Living Fossil\t\t\t<\/a>\n\t\t<\/h2>\n\t\t<p><img loading=\"lazy\" loading=\"lazy\" decoding=\"async\" class=\"fltlft alignleft\" src=\"http:\/\/nowthatswild.com\/evolution\/images\/ginkgo.jpg\" alt=\"ginko\" width=\"144\" height=\"137\" \/>The Ginkgo tree is a living fossil. The speed and direction of evolutionary change can vary in a species, allowing some to remain relatively unchanged for long periods of time. Newly found specimens of Ginkgo grew more than a hundred million years ago and are remarkably similar to present-day trees. There are some specimens of Ginkgo in a Chinese monastery garden that are over three thousand years old. Previous fossils have revealed the Ginkgo tree has remained unchanged for over 51 million years, and similar trees were alive and well 170 million years ago, during the Jurassic period. Although there are subtle differences in specimens from the Jurassic period, there is little doubt that this tree is a descendant of forebears that provided food for dinosaurs.<\/p>\n\t\t<\/div>\n\t\t\t\t<\/article>\n\t\t\t\t<article class=\"elementor-post elementor-grid-item post-246 post type-post status-publish format-video hentry category-evolution post_format-post-format-video\" role=\"listitem\">\n\t\t\t\t<div class=\"elementor-post__text\">\n\t\t\t\t<h2 class=\"elementor-post__title\">\n\t\t\t<a href=\"https:\/\/nowthatswild.com\/new\/the-life-of-alfred-russel-wallace\/\" >\n\t\t\t\tThe Life of Alfred Russel Wallace\t\t\t<\/a>\n\t\t<\/h2>\n\t\t<div class=\"elementor-post__content\"><style>.elementor-246 .elementor-element.elementor-element-94cfaf2 .elementor-wrapper{--video-aspect-ratio:1.77777;}<\/style>\t\t<div data-elementor-type=\"wp-post\" data-elementor-id=\"246\" class=\"elementor elementor-246\" data-elementor-post-type=\"post\">\n\t\t\t\t\t\t<section class=\"elementor-section elementor-top-section elementor-element elementor-element-bf730f5 elementor-section-boxed elementor-section-height-default elementor-section-height-default\" data-id=\"bf730f5\" data-element_type=\"section\" data-e-type=\"section\">\n\t\t\t\t\t\t<div class=\"elementor-container elementor-column-gap-default\">\n\t\t\t\t\t<div class=\"elementor-column elementor-col-100 elementor-top-column elementor-element elementor-element-ba123b8\" data-id=\"ba123b8\" data-element_type=\"column\" data-e-type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t<div class=\"elementor-element elementor-element-94cfaf2 elementor-widget elementor-widget-video\" data-id=\"94cfaf2\" data-element_type=\"widget\" data-e-type=\"widget\" data-settings=\"{&quot;youtube_url&quot;:&quot;https:\\\/\\\/youtu.be\\\/H8q3my7ujws&quot;,&quot;video_type&quot;:&quot;youtube&quot;,&quot;controls&quot;:&quot;yes&quot;}\" data-widget_type=\"video.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<div class=\"elementor-wrapper elementor-open-inline\">\n\t\t\t<div class=\"elementor-video\"><\/div>\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<\/div>\n\t\t<\/div>\t\t<\/div>\n\t\t\t\t<\/article>\n\t\t\t\t<article class=\"elementor-post elementor-grid-item post-250 post type-post status-publish format-standard hentry category-evolution\" role=\"listitem\">\n\t\t\t\t<div class=\"elementor-post__text\">\n\t\t\t\t<h2 class=\"elementor-post__title\">\n\t\t\t<a href=\"https:\/\/nowthatswild.com\/new\/is-that-salad-dressing-i-smell\/\" >\n\t\t\t\tIs That Salad Dressing I Smell?\t\t\t<\/a>\n\t\t<\/h2>\n\t\t<p class=\"pageTitle\"><img loading=\"lazy\" loading=\"lazy\" decoding=\"async\" class=\"fltlft alignleft\" src=\"http:\/\/nowthatswild.com\/evolution\/images\/sarah2.jpg\" alt=\"Sarah\" width=\"214\" height=\"271\" \/>Bugs. Creepy crawlies. Beasties. Those little critters with exoskeletons- otherwise known as arthropods. The group that includes insects, like bumblebees and cockroaches, arachnids, like spiders and scorpions, and myriapods, like centipedes and millipedes.<\/p>\n<p class=\"whiteParagraph\">Most bugs are little. Even the ones we think of as being big, like tarantulas or luna moths, are pretty little compared to us and most animals. So if you\u2019re a bug, one thing you have to worry about is that there are probably big animals out there who want to catch you and eat you for lunch. To address this problem several bugs have evolved a lot of really clever ways to stay safe from all those big, hungry animals. Some bugs can run really fast, some are camouflaged, and some have painful stingers. And then there are bugs that have truly unique forms of self-defense.<\/p>\n<p class=\"whiteParagraph\">One bug that has evolved a distinctive way of protecting itself is a vinegaroon, or whip scorpion. Vinegaroons are arachnids, which means they have eight legs, two body parts and no antennae. They look quite similar to true scorpions, except they\u2019re missing the thick tail with the stinger at the end, and they\u2019re missing the scorpion\u2019s venom that\u2019s in that stinger. Instead, vinegaroons have a flagellum (a thin whip-like appendage \u2013 but from this point on we\u2019ll just call it a tail) that they use as a feeler because they don\u2019t have very good eyesight.<\/p>\n<p class=\"whiteParagraph\"><img loading=\"lazy\" loading=\"lazy\" decoding=\"async\" class=\"fltrt alignright\" src=\"http:\/\/nowthatswild.com\/evolution\/images\/VinegaroonEdited.jpg\" alt=\"vinegaroon\" width=\"339\" height=\"275\" \/>Vinegaroons have a gland in their abdomens that produces a solution that is mainly acetic acid. Acetic acid is the same acid that\u2019s in vinegar. That\u2019s right \u2013 vinegar. When a vinegaroon feels alarmed or threatened by the presence of a predator, it secretes some of this solution from the base of its tail.<\/p>\n<p class=\"whiteParagraph\">Now, you may think of vinegar as a tasty ingredient in Italian salad dressing and dill pickles. But in the wild, animals don\u2019t eat salad dressing or dill pickles, and when an animal gets a spray of vinegar in its face, it doesn\u2019t like it very much. It doesn\u2019t like the smell, it doesn\u2019t like the taste, and it doesn\u2019t like the burning that results if the acid gets in its eyes. And if the predator is another arthropod, it doesn\u2019t like the feel of the acid seeping through its exoskeleton. So it may just decide to leave the vinegaroon alone and go in search of more appetizing prey. That little spray of acetic acid is a very effective evolved deterrent against danger.<\/p>\n<p class=\"whiteParagraph\">So if you\u2019re ever walking around on a summer night in the southwest United States or Mexico and come across a vinegaroon, and you suddenly smell vinegar, you\u2019ll know the critter isn\u2019t happy about meeting you. But, don\u2019t take it personally. To the vinegaroon, you\u2019re just another huge, hungry animal.<\/p>\n<p class=\"whiteParagraph\"><span class=\"orange\">by Sarah Rollin Naughton<\/span><br \/>\nArachnid, Arthropod &amp; Reptile Specialist: Outreach Educator, Philadelphia Zoo<br \/>\nEnvironmental Educator, Churchville Nature Center<\/p>\n\t\t<\/div>\n\t\t\t\t<\/article>\n\t\t\t\t<article class=\"elementor-post elementor-grid-item post-254 post type-post status-publish format-video hentry category-evolution post_format-post-format-video\" role=\"listitem\">\n\t\t\t\t<div class=\"elementor-post__text\">\n\t\t\t\t<h2 class=\"elementor-post__title\">\n\t\t\t<a href=\"https:\/\/nowthatswild.com\/new\/great-transitions-the-origin-of-humans\/\" >\n\t\t\t\tGreat Transitions: The Origin of Humans\t\t\t<\/a>\n\t\t<\/h2>\n\t\t<div class=\"elementor-post__content\"><style>.elementor-254 .elementor-element.elementor-element-4cff009 .elementor-wrapper{--video-aspect-ratio:1.77777;}<\/style>\t\t<div data-elementor-type=\"wp-post\" data-elementor-id=\"254\" class=\"elementor elementor-254\" data-elementor-post-type=\"post\">\n\t\t\t\t\t\t<section class=\"elementor-section elementor-top-section elementor-element elementor-element-a77c25a elementor-section-boxed elementor-section-height-default elementor-section-height-default\" data-id=\"a77c25a\" data-element_type=\"section\" data-e-type=\"section\">\n\t\t\t\t\t\t<div class=\"elementor-container elementor-column-gap-default\">\n\t\t\t\t\t<div class=\"elementor-column elementor-col-100 elementor-top-column elementor-element elementor-element-a471bf9\" data-id=\"a471bf9\" data-element_type=\"column\" data-e-type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t<div class=\"elementor-element elementor-element-4cff009 elementor-widget elementor-widget-video\" data-id=\"4cff009\" data-element_type=\"widget\" data-e-type=\"widget\" data-settings=\"{&quot;youtube_url&quot;:&quot;https:\\\/\\\/youtu.be\\\/Yjr0R0jgct4&quot;,&quot;video_type&quot;:&quot;youtube&quot;,&quot;controls&quot;:&quot;yes&quot;}\" data-widget_type=\"video.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<div class=\"elementor-wrapper elementor-open-inline\">\n\t\t\t<div class=\"elementor-video\"><\/div>\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<\/div>\n\t\t<\/div>\t\t<\/div>\n\t\t\t\t<\/article>\n\t\t\t\t<article class=\"elementor-post elementor-grid-item post-258 post type-post status-publish format-standard hentry category-evolution\" role=\"listitem\">\n\t\t\t\t<div class=\"elementor-post__text\">\n\t\t\t\t<h2 class=\"elementor-post__title\">\n\t\t\t<a href=\"https:\/\/nowthatswild.com\/new\/on-common-ground\/\" >\n\t\t\t\tOn Common Ground\t\t\t<\/a>\n\t\t<\/h2>\n\t\t<h1><span class=\"pageTitle\"><span class=\"orangeBold18pt\"><span class=\"bookReview\"><img loading=\"lazy\" loading=\"lazy\" decoding=\"async\" class=\"fltlft alignleft\" src=\"http:\/\/nowthatswild.com\/evolution\/images\/evopage%20007.jpg\" alt=\"On Common Ground\" width=\"167\" height=\"111\" \/><\/span><\/span><\/span><\/h1>\n<p><span class=\"whiteParagraph\">The story of our evolution began in Africa about six million years ago and it describes the very long process that our ancestors went through to ultimately become modern humans. Scientists believe that our common ancestor existed 5-8 million years ago. At that time, two species broke off into separate lineages, one ultimately evolving into gorillas and chimpanzees, the other into early humans called hominins.<\/p>\n<p>In the millions of years that followed, at least a dozen different species of humanlike creatures have existed and are reflected in fossil discoveries, although many of these are close relatives and not actual ancestors of modern humans. It is important to remember the line of ancestry does not represent a straight line to us. Many of these early hominids left no descendants and simply died out. Still, others are very likely direct ancestors of modern humans. While scientists still do not know the total number of hominid species that existed, because new fossils are continually being discovered, the story of human evolution becomes clearer all the time.<\/span><\/p>\n\t\t<\/div>\n\t\t\t\t<\/article>\n\t\t\t\t<article class=\"elementor-post elementor-grid-item post-261 post type-post status-publish format-standard hentry category-evolution\" role=\"listitem\">\n\t\t\t\t<div class=\"elementor-post__text\">\n\t\t\t\t<h2 class=\"elementor-post__title\">\n\t\t\t<a href=\"https:\/\/nowthatswild.com\/new\/horse-evolution\/\" >\n\t\t\t\tHorse Evolution\t\t\t<\/a>\n\t\t<\/h2>\n\t\t<div class=\"elementor-post__content\"><style>.elementor-261 .elementor-element.elementor-element-07b5df0 .elementor-wrapper{--video-aspect-ratio:1.77777;}<\/style>\t\t<div data-elementor-type=\"wp-post\" data-elementor-id=\"261\" class=\"elementor elementor-261\" data-elementor-post-type=\"post\">\n\t\t\t\t\t\t<section class=\"elementor-section elementor-top-section elementor-element elementor-element-a4dad3b elementor-section-boxed elementor-section-height-default elementor-section-height-default\" data-id=\"a4dad3b\" data-element_type=\"section\" data-e-type=\"section\">\n\t\t\t\t\t\t<div class=\"elementor-container elementor-column-gap-default\">\n\t\t\t\t\t<div class=\"elementor-column elementor-col-100 elementor-top-column elementor-element elementor-element-243cb14\" data-id=\"243cb14\" data-element_type=\"column\" data-e-type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t<div class=\"elementor-element elementor-element-07b5df0 elementor-widget elementor-widget-video\" data-id=\"07b5df0\" data-element_type=\"widget\" data-e-type=\"widget\" data-settings=\"{&quot;youtube_url&quot;:&quot;https:\\\/\\\/youtu.be\\\/GO1L8cqxPp0&quot;,&quot;video_type&quot;:&quot;youtube&quot;,&quot;controls&quot;:&quot;yes&quot;}\" data-widget_type=\"video.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<div class=\"elementor-wrapper elementor-open-inline\">\n\t\t\t<div class=\"elementor-video\"><\/div>\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-33bc722 elementor-widget elementor-widget-text-editor\" data-id=\"33bc722\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<cite class=\"author\"><span class=\"orange\">Video written by Nicole Reggia, Produced by Dave Bock, Now That&#8217;s Wild.com<\/span><\/cite>\n\n<span class=\"author\">Horse Evolution<\/span>\u00a0&#8211; The evolution of the horse occurred over a period of 50 million years, transforming the small, dog-sized, forest dwelling Eohippus into the modern horse.\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<\/div>\n\t\t<\/div>\t\t<\/div>\n\t\t\t\t<\/article>\n\t\t\t\t<article class=\"elementor-post elementor-grid-item post-265 post type-post status-publish format-standard hentry category-evolution\" role=\"listitem\">\n\t\t\t\t<div class=\"elementor-post__text\">\n\t\t\t\t<h2 class=\"elementor-post__title\">\n\t\t\t<a href=\"https:\/\/nowthatswild.com\/new\/decoding-dolphins\/\" >\n\t\t\t\tDecoding Dolphins\t\t\t<\/a>\n\t\t<\/h2>\n\t\t<p><img loading=\"lazy\" loading=\"lazy\" decoding=\"async\" class=\"fltlft aligncenter\" src=\"http:\/\/nowthatswild.com\/evolution\/images\/ntwpic3%20043.jpg\" alt=\"Dolphins\" width=\"236\" height=\"156\" \/><\/p>\n<p><span class=\"whiteParagraph\">The ancestor of today&#8217;s dolphin appeared on Earth about 95 million years ago. Mesonix was a terrestrial animal that waded into shallow water to feed, had four legs and a body covered with hair. In the next 20 million years, Mesonix adapted to living in the water and forelegs became pectoral flippers while hind legs began to disappear. Vestigial hind limbs are still present in modern day dolphins in the form of rod-shaped pelvic bones and pectoral flippers house all the carpal and metacarpal bones of hands like yours and mine. As a result of evolution, the nostrils of early dolphins migrated from the nose to the top of the head to make it easier to breath while swimming or resting in the water.<\/p>\n<p>The Tokyo Institute of Technology recently decoded the DNA sequences of the dolphin genome showing that these whales are closely related to cows, giraffes, pigs and antelope, with the closest being the hippo. The dolphin&#8217;s 3-chambered stomach functions the same way as the 4-chambered cow&#8217;s, providing more evidence of their link. Dr. David Busbee of Texas A &amp; M University has discovered that dolphins and humans share many similar chromosomal similarities. Dolphins and whales have an excellent fossil record and they are one of the best examples of evolutionary transition showing their movement from land to water.<\/span><\/p>\n\t\t<\/div>\n\t\t\t\t<\/article>\n\t\t\t\t<article class=\"elementor-post elementor-grid-item post-268 post type-post status-publish format-standard hentry category-evolution\" role=\"listitem\">\n\t\t\t\t<div class=\"elementor-post__text\">\n\t\t\t\t<h2 class=\"elementor-post__title\">\n\t\t\t<a href=\"https:\/\/nowthatswild.com\/new\/charles-darwin\/\" >\n\t\t\t\tCharles Darwin\t\t\t<\/a>\n\t\t<\/h2>\n\t\t<table border=\"0\" width=\"935\" cellspacing=\"12\" cellpadding=\"24\">\n<tbody>\n<tr>\n<td class=\"blueBox\" colspan=\"2\">\n<p class=\"whiteParagraph\"><img loading=\"lazy\" loading=\"lazy\" decoding=\"async\" class=\"fltrt alignleft\" src=\"http:\/\/nowthatswild.com\/evolution\/images\/darwin.png\" width=\"230\" height=\"259\" \/><\/p>\n<p class=\"whiteParagraph\">In October 1831, the 90-foot vessel named the HMS Beagle set sail for a 5-year voyage around the world that would inspire a young Charles Darwin to transform his thinking into developing his ideas of evolution to explain biological change.<\/p>\n<p class=\"whiteParagraph\">Darwin&#8217;s exposure to specimens all over the globe led him to believe that they had gradually evolved from common ancestors.

Advances in physics, molecular biology, geology, genetics and chemistry have refined, supported and expanded evolutionary concepts beyond anything Darwin could have imagined.<\/p>\n\t\t<\/div>\n\t\t\t\t<\/article>\n\t\t\t\t<article class=\"elementor-post elementor-grid-item post-278 post type-post status-publish format-standard hentry category-evolution\" role=\"listitem\">\n\t\t\t\t<div class=\"elementor-post__text\">\n\t\t\t\t<h2 class=\"elementor-post__title\">\n\t\t\t<a href=\"https:\/\/nowthatswild.com\/new\/faq-are-all-species-related\/\" >\n\t\t\t\tFAQ: Are all species related?\t\t\t<\/a>\n\t\t<\/h2>\n\t\t<p><img loading=\"lazy\" loading=\"lazy\" decoding=\"async\" class=\"alignleft\" style=\"font-weight: inherit;\" src=\"http:\/\/nowthatswild.com\/evolution\/images\/evoFAQ_palm.png\" alt=\"NTW Palm\" width=\"189\" height=\"189\" \/><\/p>\n<p><strong>Yes.<\/strong> All organisms, both living and extinct, are related.

There are many, many transitional forms that have been found between all kinds of distinct taxonomical groups, including in our ancestral line. The news is filled almost daily with new discoveries that show the transitions and adaptations of species. There are many well preserved fossils that show the transitions of things like scales to feathers and toes to hooves and they are on display in museums for everyone to see and study. DNA sequencing has provided further evidence with adaptations occurring at the right time in the geographical record to support these transitions. Several discoveries within our own human lineage fulfilled the predictions that humans share a common ancestor with modern African apes, like the gorillas and chimpanzees.<\/p>\n\t\t<\/div>\n\t\t\t\t<\/article>\n\t\t\t\t<article class=\"elementor-post elementor-grid-item post-291 post type-post status-publish format-standard hentry category-evolution\" role=\"listitem\">\n\t\t\t\t<div class=\"elementor-post__text\">\n\t\t\t\t<h2 class=\"elementor-post__title\">\n\t\t\t<a href=\"https:\/\/nowthatswild.com\/new\/faq-what-is-natural-selection\/\" >\n\t\t\t\tFAQ: What is natural selection?\t\t\t<\/a>\n\t\t<\/h2>\n\t\t<p class=\"whiteParagraph\"><img loading=\"lazy\" loading=\"lazy\" decoding=\"async\" class=\"fltrt alignleft\" src=\"http:\/\/nowthatswild.com\/evolution\/images\/evoFAQ_blackSwallowtail.png\" alt=\"NTW Black Swallowtail\" width=\"189\" height=\"189\" \/>Natural selection is the process by which species adapt to their environment and form a new, separate species. It leads to evolutionary change when individuals with certain characteristics have a greater survival or reproduction rate than other individuals in a population and pass these inheritable genetic characteristics to their offspring. The idea of &#8220;survival of the fittest&#8221; is a misconception. It is more like &#8220;survival of the fittest for the times&#8221; and even then the so called &#8220;fittest&#8221; may not be the one to survive. Many things like disease, climate, geography, resources and predation can all determine what traits get passed on to future generations. It is important to remember that natural selection does not produce a straight line to perfection which is evident because most of life that existed on Earth is extinct. Natural selection can take a long time and can only make improvements on the existing models of life.<\/p>\n\t\t<\/div>\n\t\t\t\t<\/article>\n\t\t\t\t<article class=\"elementor-post elementor-grid-item post-294 post type-post status-publish format-standard hentry category-evolution\" role=\"listitem\">\n\t\t\t\t<div class=\"elementor-post__text\">\n\t\t\t\t<h2 class=\"elementor-post__title\">\n\t\t\t<a href=\"https:\/\/nowthatswild.com\/new\/faq-does-sex-play-a-role-in-evolution\/\" >\n\t\t\t\tFAQ: Does sex play a role in evolution?\t\t\t<\/a>\n\t\t<\/h2>\n\t\t<p class=\"whiteParagraph\"><img loading=\"lazy\" loading=\"lazy\" decoding=\"async\" class=\"fltlft alignright\" src=\"http:\/\/nowthatswild.com\/evolution\/images\/evoFAQ_sexsRole.png\" alt=\"NTW Role of Sex in Evolution\" width=\"189\" height=\"189\" \/>Yes. Sexual selection allows an organism to combine half of its genes with the half of another and these new combinations of genes are passed to the following generations. It is this genetic diversity that provides the opportunity for a species to change over time. Sexual selection is a very powerful drive in organisms. Peacocks, for example, produce and maintain beautiful, extravagant feathered trains to attract mates. These feathers are harmful to the individual bird\u2019s survival and are likely to attract predators as well as interested members of the opposite sex and they slow down the male birds in fighting, fleeing and flying. Studies have shown that peahens select and mate with peacocks with the biggest tails that advertise the fitness level of their genes.<\/p>\n\t\t<\/div>\n\t\t\t\t<\/article>\n\t\t\t\t<article class=\"elementor-post elementor-grid-item post-296 post type-post status-publish format-standard hentry category-evolution\" role=\"listitem\">\n\t\t\t\t<div class=\"elementor-post__text\">\n\t\t\t\t<h2 class=\"elementor-post__title\">\n\t\t\t<a href=\"https:\/\/nowthatswild.com\/new\/faq-what-is-speciation\/\" >\n\t\t\t\tFAQ: What is speciation?\t\t\t<\/a>\n\t\t<\/h2>\n\t\t<p class=\"whiteParagraph\"><img loading=\"lazy\" loading=\"lazy\" decoding=\"async\" class=\"fltrt alignleft\" src=\"http:\/\/nowthatswild.com\/evolution\/images\/evoFAQ_speciation.png\" alt=\"NTW Speciation\" width=\"189\" height=\"189\" \/>Speciation is the progress of how one species splits into two different, distinct species which no longer can interbreed with each other. Speciation occurs when a group within a species separates from other members of its species and develops its own unique characteristics. The demand of a different environment can differentiate the new species from its ancestors. It is important to remember that populations of species evolve, rather than individuals. Although it can sometimes be a slow process, speciation provides and helps to explain the vast amount of diversity we see on our planet.<\/p>\n\t\t<\/div>\n\t\t\t\t<\/article>\n\t\t\t\t<article class=\"elementor-post elementor-grid-item post-298 post type-post status-publish format-standard hentry category-evolution\" role=\"listitem\">\n\t\t\t\t<div class=\"elementor-post__text\">\n\t\t\t\t<h2 class=\"elementor-post__title\">\n\t\t\t<a href=\"https:\/\/nowthatswild.com\/new\/faq-what-is-the-relationship-between-time-and-evolution\/\" >\n\t\t\t\tFAQ: What is the relationship between time and evolution?\t\t\t<\/a>\n\t\t<\/h2>\n\t\t<p class=\"whiteParagraph\"><img loading=\"lazy\" loading=\"lazy\" decoding=\"async\" class=\"fltlft alignright\" src=\"http:\/\/nowthatswild.com\/evolution\/images\/evoFAQ_timeEvo.png\" alt=\"NTW Time &amp; Evolution\" width=\"189\" height=\"189\" \/>If you wanted to squeeze the 3.5 billion years of the history of life on Earth into a single minute, you would have to wait about 50 seconds for multicellular life to evolve, another four seconds for vertebrates to invade the land, and another four seconds for flowers to evolve- and only in the last 0.002 seconds would &#8220;modern&#8221; humans arise. It can take many generations to produce the changes over time that we see in plants and animals. Most, but not all, of this change takes place over thousands of years. It is sometimes hard to grasp these long time spans of change because of our own limited time on Earth.<\/p>\n\t\t<\/div>\n\t\t\t\t<\/article>\n\t\t\t\t<article class=\"elementor-post elementor-grid-item post-300 post type-post status-publish format-standard hentry category-evolution\" role=\"listitem\">\n\t\t\t\t<div class=\"elementor-post__text\">\n\t\t\t\t<h2 class=\"elementor-post__title\">\n\t\t\t<a href=\"https:\/\/nowthatswild.com\/new\/faq-why-is-it-important-to-teach-evolution\/\" >\n\t\t\t\tFAQ: Why is it important to teach evolution?\t\t\t<\/a>\n\t\t<\/h2>\n\t\t<p><img decoding=\"async\" class=\"alignleft\" src=\"http:\/\/nowthatswild.com\/evolution\/images\/evoFAQ_God.png\" alt=\"NTW Refute the presence of God?\" \/><\/p>\n<p class=\"whiteParagraph\">Understanding evolution is critical for understanding biology. As the preeminent scientist Theodosius Dobzhansky stated, \u201cNothing in biology makes sense except in the light of evolution.\u201d Evolution is the only scientific explanation for the diversity of life. It explains the striking similarities among vastly different forms of life, the changes that occur within populations, and the development of new life forms. Excluding evolution from the science curricula or compromising its treatment deprives students of this fundamental and unifying scientific concept to explain the natural world.<\/p>\n<p class=\"whiteParagraph\">Teaching and learning about evolution has immense practical value that extends beyond understanding our world. The principles of evolution underlie improvements in crops, livestock, and farming methods. Natural selection accounts for the rise in pesticide resistance among agricultural pests and informs the design of new technologies to protect crops from insects and disease. Scientists are applying lessons from evolutionary biology to environmental conservation: plants and bacteria adapted to polluted environments are being used to replenish lost vegetation and to clean up toxic environments. Species from microbes to mammals adapt to climate change; studying the mechanism and rate of these changes can help conservation experts formulate appropriate measures to protect species facing extinction.<\/p>\n<p class=\"whiteParagraph\">Understanding evolution is also central to the advancement of medicine. Indeed, the entire field of \u201cevolutionary medicine\u201d is devoted to using the principles of evolution to study and treat human illness and disease. Concepts such as adaptation and mutation inform therapies and strategies to combat pathogens, including influenza. Models developed by evolutionary biologists have shed light on genetic variation that may account for an increased risk of Alzheimer\u2019s and coronary heart disease. Knowing the evolutionary relationships among species allows scientists to choose appropriate organisms for the study of diseases, such as HIV. Scientists are even using the principles of natural selection to identify new drugs for detecting and treating diseases such as cancer.<\/p>\n<p class=\"whiteParagraph\">Studying evolution is an excellent way for students to learn about the process of scientific inquiry. Evolution offers countless and diverse examples of the ways scientists gather and analyze information, test competing hypotheses, and ultimately come to a consensus about explanations for natural phenomena. Understanding science is essential for making informed decisions and has become increasingly important for innovation and competitiveness in the 21st century workplace. It is critical, therefore, that students receive a sound science education including evolution.<\/p>\n<p class=\"whiteParagraph\">Removing evolution from the science classroom or allowing it to be compromised not only deprives students of a fundamental tenet of biology and medicine, but it will undermine their understanding of how scientific knowledge is amassed.<\/p>\n\t\t<\/div>\n\t\t\t\t<\/article>\n\t\t\t\t<\/div>\n\t\t\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<section
