Darwin's Theory of Evolution plays a big part in the real world. First of all it keeps major animals and organisms from going extinct. It lets them adapt so they can keep well fed or just hide from predators. For example, there are different turtles around the world that function way differently. There necks are different so they can access their food. Ther shells can be different so they can stay protected and dry from the rain. There are many more species that have this, but a turtle is the main example.

The theory of evolution acts or Natural selection, it is on the limited resources and they have to adapt to their environment to find food.

2. What were Lamarck’s ideas about evolution? - That organisms could change during their lifetime by selectively using or not not using various parts of their body.

3. What does natural selection directly act on? - Phenotype

1. Evolution  - Process of change over time.

2. Charles Lyell  - Introduced the idea of uniformitarianism.

3. Charles Darwin  - Came up with the Natural Selection theory.

4. Uniformitarianism  - Idea that geological processes we see today are the same process from millions of years ago.

5. Jean-Baptiste Lamarck - Proposed hypothesis that organisms could change in their lifetime by selectively using and not using parts of their bodies.

6. Acquired characteristics - Traits altered by an individual organism during its life.

7. Artificial selection - Process in which nature provides the variations, and humans select those they find useful.

8. Adaptation - Any heritable characteristic that increases an organism's ability to survive and reproduce in its environment.

9. Fitness  - How well an organism can survive and reproduce in its environment.

10. Natural selection  - The process in which organisms that are best suited to their environment survive and reproduce.
