| A | B |
|---|
| temporal isolation | organisms reproducing at different times |
| vestigial | apparently useless features |
| genetic equalibrium | allele frequencies that don't significantly change over time |
| coevolution | the change of 2 or more species in close association with each other |
| convergent evolution | occurs when the environment selects similar phenotypes |
| divergent evolution | 2 or more related populations or species become more and more dissimilar |
| adaptive radiation | many related species evolove from a single ancestral species |
| artificial selection | breeding of organisms by humans for specific characteristics |
| hardy weinberg | calculates gene frequency in a population |
| sources of genetic variation | mutations and sexual reproduction |
| transitional fossil | shows features of two unlike organisms |
| 1st living organisms on earth | bacteria |
| most recently evolved organisms on earth | mammals |
| this group of organisms evolved from amphibians | reptiles |
| one species diverging into two or more species | speciation |
| missing link | has characteristics of two different animal groups |
| microevolution | a species obtaining slight differences over time |
| macroevolution | unlike organisms descended from a common ancestor |
| selective pressure | environmental factor causing organisms to evolve |
| gene pool | all genes of a species |
