| mother nature [environmental factors] decides who survives & reproduces | natural selection |
| any helpful trait that helps you survive and reproduce better than others in a population | adaptation |
| differences in a population | variation |
| having more offspring than the environment can support | overproduction |

| humans do the choosing for other species | artificial selection |
| type of natural selection for only 1 of the 2 extreme phenotypes | direction selection |
| type of natural selection for only the middle/intermediate phenotype | stabilizing selection |
| type of natural selection for both of the extreme phenotypes | disruptive selection |
| "type" that is physical appearance / visible traits | phenotype |
| "type" that is genetic makeup [DNA, RNA] | genotype |
| best evidence of evolution and being related | biochemistry |
| way to estimate the age of fossils | index fossils |
