| What was Lamarcks theory ? | Girrafs had to stretch to get food and their stretched neck would be inherited. |
| What is a population ? | Group of individuals that live in same area are same species and breed with each other ? |

| What is adaptation ? | Change in a species because it can survive better in its environment. |
| What is name of darwin's famous book ? | On the origin of Species by Means of Natural selection. |
| What is microevolution ? | How the frequency of genes change in a population over time. |
| What leads to species formation ? | Must be isolated and beed together under pressure of a unique environment. |
| Isolation | When two populations of the same species are separated from each other. |
| extinction | When a species disappears due change in conditions and not being fit to survive. |
| What is macroevolution ? | How a species changes over a long period of time. |
| Microevolution | The change within a species |
| Macroevolution | Change that leads to replacement of species. |
