Process by which evolutionary changes occur in living organisms over millions of years. According to Darwin’s theory of evolution, the organisms well adapted to their environment survive better than those who are not and are able to pass on their genes to many more offspring. As this process repeats over hundreds of thousands of years and the less-fit organisms become extinct, it appears as if.
