What is the process of evolution?

Answer 1

Charles Darwin, a scientist from the nineteenth century, was the creator of the theory (or law, if you wish) of evolution and its mechanism of natural selection. Let's start off with a definition: evolution is the process over time in which a species changes, for the better, in its traits in order to compete with other species. Evolution occurs via its mechanism, natural selection. According to natural selection, the fittest members of a species survive and produce offspring to whom they pass on their traits. Some members are born with mutations in their genes, and sometimes these are helpful. For example, an animal with a longer neck can reach stuff higher in a tree, meaning survival for it if there is no food at lower levels because of the others competing for it. So the surviving mutated animal gives birth and passes on its trait, which also survives, and passes it on, etc. Meanwhile, the others die out because they cannot compete with this super family of long necks. Over many generations, the only members left of the species are those with longer necks. This is, for example, how the giraffe's neck got so long over time. In basic summary, natural selection is the survival of the fittest. So over time, natural selection and competitition give way to a species evolving over time to make a species most adept at living in its environment. This is how evolution occurs.
