| 193444480 | evolution | change over time; the process by which modern organisms have descended from ancient organisms | 0 | |
| 193444482 | Artificial selection | Breeding organisms with specific traits in order to produce offspring with identical traits, like breeding bigger cows instead of small cows | 1 | |
| 193444483 | adaptation | heritable characteristic that increases an organism's ability to survive and reproduce in an environment | 2 | |
| 193444486 | fitness | how well an organism can survive and reproduce in its environment | 3 | |
| 193444491 | natural selection | process by which organisms with variations that are most suited to their environment survive and reproduce most successfully; also called survival of the fittest | 4 | |
| 193444492 | homologous structure | structures that are shared by related species and that have been inherited from a common ancestor | 5 | |
| 193444493 | analogous structure | body parts that share a common function, but not structure | 6 | |
| 193444496 | vestigial structure | structure that is inherited from ancestors but has lost much or all of its original function | 7 | |
| 193444497 | Adaptive Radiation | where groups of organisms form many new species whose adaptations allow them to fill new or vacant niches in their communities. | 8 | |
| 193444498 | Intermediate fossil | " transitional fossils" link the older & newer species. | 9 | |
| 193444499 | principle of competitive exclusion | states that if two species are competing, the species that uses the resource more efficiently will eventually eliminate the other- no two species can have the same niche | 10 | |
| 193444501 | niche | an organism's function, it's occupation, where it lives, what other animals it effects. | 11 | |
| 193444502 | empty niche | an area that usually has animals in it, if doesn't, it can then be occupied by other animals who serve the same purpose as the previous animal | 12 | |
| 193444504 | principle of common descent | All species-living and extinct-are descended from ancient common ancestors. | 13 | |
| 193444505 | endemic | only lives in a certain area, native | 14 |
