Chimps on treadmill offer human evolution insight

Chimpanzees scampering on a treadmill have provided support for the notion that ancient human ancestors began walking on two legs because it used less energy than quadrupedal knuckle-walking, scientists said.

SALT LAKE CITY Nov 18, 2004 - New research suggests that developing the ability to run long thought to be a byproduct of walking for early man was actually an instrumental step in the evolution of people from ape-like creatures into what we know today

Walking upright has long been accepted as one of the fundamental abilities that separated early human ancestors apart from their ape cousins.

WASHINGTON - A chimp-sized human ancestor walked upright 6 million years ago, far earlier than anyone had been able to show before, researchers report.

Humans evolved from ape-like ancestors because they needed to run long distances - perhaps to hunt animals or scavenge carcasses on Africaâs vast savannah â-nd the ability to run shaped our anatomy, making us look like we do today.

Why did humans evolve to walk upright? Perhaps because it's just plain easier. Make that "energetically less costly," in science-speak, and you have the conclusion of researchers who are proposing a likely reason for our modern gait.

To err may be human, but so, too, may be the ability to run. Specifically, the ability to run long distances across the African savannah may have given human ancestors an evolutionary advantage

The evolution of a physique for long-distance running is what made humans look the way we do now. The crucial role of running in human evolution, overlooked in previous research, is being proposed in an article
