Humans created crops such as corn, kale, and cabbage through

• artificial selection

• natural selection

• mutations

• genetic drift

Each scenario represents a different mechanism for evolution; match them:

• artificial selection

• An elk dies from a broken leg & cannot pass on its genes

• natural selection

• The O blood type exists due to the lack of a protein that people with type A or B would have.

• genetic drift

• humans created varieties of crop foods from wild plants

• mutation

• light colored snails on the beach survive better because their predators cannot see them
