Answer to Question #229411 in Evolution for Candy

Question

Use the theory of natural selection to explain the changes seen in the mating calls of the new isolated southern male frogs.

Answer 1

All frogs reproduce sexually, and all hatch from eggs. In almost all frogs, egg fertilization happens outside the female's body instead of inside. The female releases her eggs and the male releases his sperm at the same time.The male climbs onto the female's back and clasps his forelegs around her middle.
