| Species | a group of genetically similar organisms that can interbreed and produce fertile offspring |
| Population | a group of organisms of the same species living in a given place and time |
| Adaptation | changing of a species to become better suited to its environment/occurs as a result of natural selection |
| What is responsible for inheritied traits? | genes |
| what causes the frequency of certain alleles in a population to vary over time? | Natural Selection |
| mesonychids | hypothesized link between modern whales and hoofed mammals |
| inherited traits | links major classes of vertebrates |
| paleontologist | studies fossils |
| vestigial structures | have no use or little use and are evidence of an organisms evolutionary past |
| homologous structure | structures that share a common ancestry |
| vertebrate embryos | pharyngeal pouches and tails that are evidence of evolution |
| Extinct | when a species permanently disappears |
| Galapogos Islands | Darwin studied finches and how their beaks adapted to the food there |
