let's dig a little deeper

" least some Paleo ideas contradict leading thinking about the biomechanics of human evolution. Modern advocates of paleo-style exercise argue for the value of short bursts of cardiovascular exertion that may also include hauling a heavy weight, as you might after a successful hunt. "[N]o caveman ever jogged for miles while pursuing dinner or being chased by a predator," writes De Vany. "You either or sprinted or starved, or were dinner yourself."

"But that's not true, says human evolutionary biologist Daniel Lieberman, who runs a skeletal biology research lab at Harvard University. In fact, it's "demonstrably wrong," he insists. The human talent for long-distance running is unique among primates, and it's one we came by out of necessity. Some two million years ago, we began to develop a suite of adaptations, key among them sweating, that allowed for sustained exertion and were fully in place by Paleolithic times.

"Meta-data on nearly 500 hunter-gatherer tribes analyzed by Lieberman's Harvard colleague Frank Marlowe indicates that your average Paleolithic hunter probably ran up to 14 km (9 mi.) a day during persistence hunting, in which the group tracked and chased prey until the beast collapsed from overheating.",8599,2044343,00.html
