The primary difference natural and artificial selection is

• In nature selection the “pressure” comes from the environment; In artificial selection the “pressure” comes from humans (or another species).

• In artificial selection the “pressure” comes from the environment; In natural selection the “pressure” comes from humans (or another species).

• Natural selections is when humans breed the animal; Artificial selection is when humans direct genes directly.

• They are different terms for the same concept.
