Speciation Through Reproductive Isolation Quiz

Some female peacocks prefer males with large, colorful tales while other female peacocks prefer males with no tail at all. Females are now mating only with the tail they prefer. What type of reproductive barrier is this?

Gentoo penguins will present a mate with a pebble that they find to attract a mate. Emperor penguins have a specific call and movement that they make to attract a mate. Which type of isolation do these penguins demonstrate?

• temporal isolation 
• behavioral isolation
• geographical isolation
• anatomical isolation

In the Great Lakes region of North America, gray wolves and coyotes are similar species but do not mate because their breeding periods occur at different times of the year.

• Geographic isolation

• Behavioral isolation

• Temporal isolation

The American toad (Anaxyrus americanus) and Fowler's toad (Bufo fowleri) live in the same area. However, The American toad mates in early summer while Fowler’s mates in late summer.

• Geographic isolation

• Behavioral isolation

• Temporal isolation

Albert’s squirrel and the Kaibab squirrel are distinct subspecies that live on opposite sides of the Grand Canyon. They were once one species, but now differ significantly, including fur coloring.

• The image shows analogous structures that can be compared to show speciation.

• The image shows convergent evolution that represents the speciation of Darwin's Finches.

• The image shows that Darwin's Finch's demonstrates the Founder Effect through adaptive radiation, geographical reproductive isolation where natural selection caused speciation.

• The image shows organisms that are not closely related.
