Climate chnage accelerating Evolution in some species

Scientists have mostly discussed and understood evolution as a process whose effect can only be ascertained over the course of thousands, if not millions of years. In essence, evolution is defined as a change in a population's genetic composition over many generations, due to the effect of natural selection acting on individual genetic variation, that results in the development of new species. And although this notion still holds true for the most part, researchers have increasingly begun to notice the growing role that climate change has played in accelerating the rate of evolution in certain species.
