Genetics selection evo
WebOver geologic time, directional selection leads to major changes in morphology and ways of life. Evolutionary changes that persist in a more or less continuous fashion over long periods of time are known as evolutionary trends. WebThe study of evolution was confined almost entirely to genetic evolution, relegating the study of human cultural change to other disciplines. It was not until the 1970s that …
