Document Summary
Evolution the process by which different kinds of living organisms are thought to have developed and diversified from earlier forms during the history of the earth. Natural selection the process whereby organisms better adapted to their environment tend to survive and produce more offspring. The theory of its action was first fully expounded by charles darwin and is now believed to be the main process that brings about evolution. The process of rapid change in a short amount time and a long period of nothingness. A breeding experiment in which the parental varieties for one character/trait only. A genetic scenario where neither allele is dominant or recessive and both get expressed is. Pleiotrophy the production by a single gene of two or more apparently unrelated effects. A gradual path of evolution with an average rate of change. When there is a lot of extinction, animals need to fill roles.
