Natural Selection
| Question | Answer |
|---|---|
| Evolution | Process in which populations gradually change over time |
| Charles Darwin | Developed the idea of natural selection Studied finches on the Galapagos Islands 5 year trip on HMS Beagle |
| Natural Selection | The process by which individuals that are better adapted to their environment |
| Adaptation | a characteristic that improves an individual's ability to survive and reproduce in a particular environment |
| Mutation | a change in the nucleotide-base sequence of a gene or DNA molecule |
| Inherited Trait | A characteristic that can be passed from parent to offspring through genes. |
| Darwin observed different beaks in finches. Why do you think they varied? | They varied to best meet the needs of the birds (so they could get more food) |
| What does the phrase "survival of the fittest" refer to? | Those best adapted to their environment will survive and reproduce. |
| Homologous Structures | similar structures that related species have inherited from a common ancestor |
| Genetic Variation | allows natural selection to occur, and this increases the ability of organisms to survive changes in their environment and ultimately reproduce. |
