Evolution

Question 1

What are the four mechansims of evolution?

Answer 1

1. Mutation
2. Gene flow
3. Genetic drift
4. Natural selection

Question 2

What is natural selection?

Answer 2

Natural selection is the process through which populations of living organisms adapt and change. Individuals in a population are naturally variable, meaning that they are all different in some ways. This variation means that some individuals have traits better suited to the environment than others.

Question 3

What is gene flow?

Answer 3

Gene flow is also called gene migration. Gene flow is the transfer of genetic material from one population to another. Gene flow can take place between two populations of the same species through migration, and is mediated by reproduction and vertical gene transfer from parent to offspring.
