Natural Selection and Evolution

Two populations of the same species do not have the same mating rituals or signals.

• geographical isolation

• temporal isolation

• adaptive ratiation

• behavioral isolaton

Refer to the picture. This is representing

• Directional selection

• Disruptive selection

• Stabilizing selection

• Artificial selection
