Variation
500
The three factors of natural selection
What is overproduction, variation, and competition.
500
Explain the difference between artificial and natural selection.
Artificial selection is done by humans and focuses on the traits that we find to be the most valuable to us. Natural selection is done by nature and is focused on the traits that would survive best in the environment.
