What killed the mammoths
and other behemoths that once roamed the Americas?
This mammalogist thinks it may have been hyperlethal disease.

An Interview with Ross MacPhee

Around 11,000 years ago, at the end of the Pleistocene epoch, North America witnessed an extinction that claimed its mammoths, giant ground sloths, camels and numerous other large-bodied animals. Exactly what happened to these megafauna is unknown. Indeed, researchers have puzzled over their disappearance for decades. Traditional explanations hold that either dramatic climate shifts, or human hunting (overkill) extinguished these species. But in recent years a new hypothesis has emerged. According to Ross D. E. MacPhee, curator of mammalogy at the American Museum of Natural History in New York City, extremely lethal disease, brought over by humans unwittingly when they arrived in the New World, may have wiped out those Ice Age giants.

The young dolphin gives a quick flip of her head, and an undulating silver ring appears--as if by magic--in front of her. The ring is a solid, toroidal bubble two feet across--and yet it does not rise to the surface! It stands erect in the water like the rim of a magic mirror, or the doorway to an unseen dimension. For long seconds the dolphin regards its creation, from varying aspects and angles, with its vision and sonar. Seemingly making a judgement, the dolphin then quickly pulls a small silver donut from the larger structure, which collapses into small bubbles. She then "pushes" the donut, which stays just inches ahead of her rostrum, perhaps 20 feet over a period of up to 10 seconds. Then, stopping again, she regards the twisting ring for a last time and bites it--causing it to collapse into a thousand tiny bubbles which head--as they should--for the water's surface. After a few moments of reflection, she creates another.
