| Darwin | did not know about genetics, explained how species changed over time |
| Sources of information | Malthus, Lyell, Galapagos, selective breeding |
| Finches | different beaks |
| Adaptation | change in behavior or appearance in response to the environment |
| Natural Selection | individuals better suited survive and reproduce, ex:, separation, adaptation, division |
| Evolution | pop change slowly over time |
| Speciation | begins with isolation |
| Trait | characteristic passed from parent to offspring |
| Selective Breeding | ex:, choosing parents because of the presence of a trait, not natural selection |

| Population | |
| Limitations | starvation, disease, competition, predators |
| Inherited variation | offspring are different |
| Fossils | buried remains of plants and animals |
| Relative age | deeper fossils= older |
| Division | separated groups can not mate |
| Competition | (struggle to survive) |
| Successful reproduction | surviving and passing traits to offspring |
| DNA | similar in closely related species |
| Speciation | formation of a species, starts with isolation |
| Selective breeding | breeding animals with desirable traits |
| Population | same species living in the same place at the same time |
| Species | look alike and produce fertile offspring |
