Evolution Vocabulary Review

Match the following terms to their definition.

• Evolution

• a unit of heredity which is transferred from a parent to offspring and is held to determine some characteristic of the offspring.

• Gene

• the changing of the structure of a gene, resulting in a variant form that may be transmitted to subsequent generations, caused by the alteration of single base units in DNA, or the deletion, insertion, or rearrangement of larger sections of genes or chromosomes.

• Mutation

• 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.

• Genetic Drift

• 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.

• Natural Selection

• variation in the relative frequency of different genotypes in a small population, owing to the chance disappearance of particular genes as individuals die or do not reproduce.
