| Convergent evolution | when species develop similar characteristics that suit their environment |
| Divergent evolution | suggests that many species develop from a common ancestor |
| Co-evolution | occurs when two or more organisms evolve in response to each other. Ex: hummingbird and the fuchsia plant |
| Fitness | the ability of an organism to live, survive, and reproduce in that environment |
| Gene flow | the change in the occurrence of genes in a population |
| Competition | the fight among living things to get what they need for survival |
| Natural selection | organisms best suited to the environment are the ones most likely to survive and reproduce |
| Emigration | occurs when organisms leave a population |
