evolution in action
| Term | Definition |
|---|---|
| adaptive rediation | an evolutionary pattern in which many species evolve from a single ancestral species |
| artificial selection | the selective breeding of organisms (by humans) for specific desirable characteristics |
| converganet evolution | the process by which unrelated species become more similar as they adapt to the same kind of environment |
| coevolution | the evolution of two or more species that is due to mutual influences often in a way that makes the relationship more mutually beneficial |
| divergent evolution | the process by which a species evolves into two or more descendant or different forms; also, the process of tracing two or more species back to a common ancestor |
| over production | more offspring can be produced than can survive to maturity |
| genetic variation | within a population, individuals have different traits. some of this variation is inherited |
| struggle to survive | individuals must compete with each other. some variations improve chances to survive and reproduce individuals with that variation |
| differential reproduction | organisms with the best adaptions (variations) are most likely to survive and reproduce. their adaptions become more frequent so populations become adapted to different environments |
