Animal species are affected by global climate change. Entire species can be wiped out if they fail to adapt (evolve) to survive the new climate. Animals often attempt to flee the changing climate to keep with the climate that they are used to, but those that are trapped are forced into extinction or into evolution. Fossils show that these morphological changes have taken place before. What fossils “tell us is that as you go through the past 70 million years, there are many times at which we get a changeover from one set of species to a new set of species.” The changeover is often evolution because of factors- climate change is a factor.
