  Evolution
• a structure that no longer functional

  vestigial structure

  fossils
• structures that are anatomically dissimilar but same in function

  analogous structure
• The similarity of bone structure in the forelimbs of many vertebrates is an example of

  homology

• The random loss of alleles in a population is called

  genetic drift
• The movement of new genes into a population as a result of migration or hybridization is called

  gene flow
• Mutation is a relatively unimportant source of variation and is not the foundation for evolution.
