Evolution and Natural Selection

What is natural selection?

• The process by which organisms intentionally select their offspring's traits.

• The process by which organisms randomly produce offspring.

• The process by which organisms worse adapted to their environment tend to survive and produce more offspring.

• The process by which organisms better adapted to their environment tend to survive and produce more offspring.

What is evolution?

• The process of change in only human life over generations

• The process of change in non-living things over generations

• The process of change in all forms of life over generations

What is adaptation?

• The process by which organisms change their genetic makeup to better fit their environment.

• The process by which organisms migrate to a different environment to survive and reproduce.

• The process by which organisms become extinct due to changes in their environment.

• The process by which organisms adjust to changes in their environment in order to survive and reproduce.

What is coevolution?

• The process in which two or more species evolve in the same direction due to environmental factors.

• The process in which two or more species evolve through genetic mutation.

• The process in which two or more species reciprocally affect each other's evolution through natural selection.

• The process in which two or more species evolve independently without any interaction.
