Latest Quadrupedalism Stories
Contradicting earlier claims, “The Family That Walks on All Fours,” a group of quadrupedal humans made famous by a 2006 BBC documentary, have simply adapted to their inability to walk upright and do not represent an example of backward evolution.
Resolving a long-standing mystery in human evolution, new research from the RIKEN Brain Science Institute indicates that early hominids developed finger dexterity and tool use ability before the development of bipedal locomotion.
Researchers have found that bipedal desert rodents manage to compete with their quadrupedal counterparts by using a diverse set of jumps, hops and skips.
Archaeologists from the University of York have challenged evolutionary theories about why our ancestors began walking upright. Publishing research in the journal Antiquity, the team wrote that our upright gait may have begun in the rugged landscape of East and South Africa.
When, how and why modern humans first stood up and walked on two legs is considered to be one of the greatest missing links in our evolutionary history.
Scientists have discovered that the reason we swing our arms while we walk can be attributed to our bodyâ€™s natural ability to conserve energy.
Despite the fact that most of us see our four-legged friends walking around every day, most of us-including many experts in natural history museums and illustrators for veterinary anatomy text books-apparently still don't know how they do it.
A new study provides support for the hypothesis that walking on two legs, or bipedalism, evolved because it used less energy than quadrupedal knucklewalking.
