| evolution | a species will gradually change over many generations and become better adapted to the new conditions |
🗑
|
||||||
| adaptation | a trait that helps an organism to survive and reproduce | Different bird beaks
🗑
|
||||||
| Natural Selection | individuals who are better adapted to their environment are more likely to survive and reproduce then the other members of the same species; over time, helpful variations gradually accumulate in a species, unfavorable variations disappear | long necks on giraffes
🗑
|
||||||
| overproduction | most species produce far more offspring than can possibly survive` | fish lay millions of eggs; not all survive
🗑
|
||||||
| competition | since food and resources are limited, offspring must compete to survive |
🗑
|
||||||
| Survival of the Fittest | Those organisms best adapted to the environment will survive and reproduce; the "strongest" survive |
🗑
|
||||||
| variation | a difference between individuals of the same species | white and brown fur in rabbits
🗑

| fossil | the preserved remains or traces of an organism that lived in the past |

||||||
| branching tree | a diagram that shows how scientists think different groups of organisms are related |
🗑
