"in biology, changes that happen over time in the gene pool of a population."

• evolution

• extinction

• mutation

body parts in different organisms that have the same basic structure, but may have different functions

• analagous structures

• homologous structures

• vestigal structures

body parts in organisms that have the same functions, but have different structures

• analagous structures

• homologous structures

• vestigal structures

body parts found in living organisms that no longer serve a purpose (not necessary for the organisms survival)

• analagous structures

• homologous structures

• vestigal structures

selective pressure exerted by humans on populations in order to improve or modify particular desirable traits

• natural selection

• artificial selection

the process by which characteristics of population change over many generations as organisms with heritable traits survive and reproduce, passing their traits to offspring
