11 terms
Terms | Definitions |
|---|---|
 Gene flow | exchange of genes with another population |
| Splinter population | A small population that breaks off from the main population, via some sort of isolation |
| Adaptive radiation | Evolution from a common ancestor that results in diverse species adapted to different environments |
| Punctuated equilibrium | Suggests that species often diverge in spurts of relatively rapid change, followed by periods of relatively no change |
| Embryology | Study of the development of organisms |
| vestigial structures | reminants of structures that may have once had important functions but appear useless now |
| homologous structures | similar structures (possibly w/ different functions) in species sharing a common ancestor |
| gene pool | all the alleles (total) in all the individuals in a population |
| hardy-weinberg equilibrium | says that the population is not evolving, and the frequency of alleles in the gene pool is not changing over time |
| bottleneck effect | what occurs after a natural disaster that is sudden, when much of a population is affected/wiped out and genetic diversity is reduced. |
| founder effect | when very few individuals colonize a new habitat, resulting in very little genetic diversity |
