The Theory of Evolution

Here is Theory of evolution video which is discussed a lot. You will see in this video mechanisms with subsubjects Mutation, Natural Selection and Genetic Drift. So, Theory of evolution... What it is, what it says, how it works in 2 minutes..

1. Mutation (Random): Changes in an organism's DNA which provide the  material for natural selection and genetic drift to work on.

2. Natural Selection (Non-Random): Diffirences in traits cause some organisms to mate at a higher rate than other organisms without the trait. The environment does the selecting.

3. Genetic Drift (Random): Random, non-selective changes in gene frequency over time.
