Walking tall
- Evolution -
LOOKS like upright walking may have started earlier than scientists thought.
Here’s an excerpt from the Associated Press article:
WASHINGTON — Maybe walking upright on two legs isn’t such a defining human feature after all. Scientists who spent a year photographing orangutans in the rain forest say the trait probably evolved in ancient apes navigating the treetops long before ancestors of humans climbed to the ground — a hypothesis that contradicts science museums the world over.
But it’s more in tune with fossil evidence, contends Robin Crompton of the University of Liverpool, who co-authored the report in Friday’s edition of the journal Science.
“An increasing number of people have been questioning this old ‘up from the apes’ idea” of how bipedalism evolved, Crompton said.
