| Evolution | a gradual change overtime by natural selection |
| Adaptations | traits that help an organism survive & reproduce |
| Example of adaptation | polar bear has white fur blends in |
| Natural Selection | Organisms with good & helpful traits survive! |
| Overproduction | each species create MORE offspring than can survive (not enough living space or food) |
| Survival of the fittest | variations make individuals better suited for living and are more likely to survive (camoflauge to hide from predators or fast to run away) |
| Fossilization | dead organisms are preserved in rock |
| The oldest fossils are found on (top or bottom) of sedimentary rock layers | bottom |
| The most complex (younger) fossils are found on the | top |
| Camoflauge is | an adaptation to blend into surroundings to avoid predators |
| Homologous structures | evidence that can show a common ancester between organisms |
