| Bipedal | Uses two legs/feet to walk/move |
| Extinction | When all of a species has died |
| Opposable Thumbs | Structures that can help some animals grasp things toward their fingers |

| adaptation | inherited characteristic that improves an organism's ability to survive and reproduce in a particular environment |
| population | group of individuals of the same species living in a particular area at the same time |
| artificial selection | selective breeding of domesticated plants and animals to produce offspring with desired genetic traits |
| Amber | a sticky substance produced by evergreen trees that hardens when it dries |
| Petrification | The process by which the remains of an organism turn to stone by replacing original substances with minerals from the water in which the organism dies. |
| species | a group of organisms that can breed with one another and produce fertile offspring in a natural environment |
| descent with modification | Darwin's idea that species of organisms originate as modified descendants of other species |
| Process of change over time | evolution |
| nucleus | compartment for the storage of genetic material |
| clades | natural groups that include an ancestor and all the groups that are descended from that ancestor |
