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.
