evolution in action

TermDefinition
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
