What is an example of an adaptation?

Back

Camouflage: A trait that allows an organism to blend in with its environment to avoid predators.

What is selective breeding?

Back

Selective Breeding: The process of breeding plants and animals for specific traits.

Front

What is the role of variation in natural selection?

Back

Variation provides the raw material for natural selection, allowing some individuals to survive and reproduce better than others.
