Shift to Polygamy

Zoologists wondered why some bird species, such as the Birds of Paradise, were polygamous. The males spend all their time looking beautiful and trying to impress the females. The prettiest, most athletic male impregnates a dozen females, but takes no rôle in caring for the offspring. Because New Guinea is a recently formed island, birds have reached it, but not many bird predators. There is plenty of food. It is a bird paradise. Life is so good that females don’t need the help of a male to raise the young. I speculate that greater ease of existence in the USA is similarly driving the switch to polygamy in the zoological sense.
