What's changed is we now have good anatomical, geological, archaeological evidence that Neanderthals are not our ancestors. When I wrote 'Lucy,' I considered Neanderthals ancestors of modern humans. We have gone back twice the age of Lucy, six million years. And we see that upright bipedal walking goes back that far in time.

The bodies we have are not made for extended use. We must cope with accumulated DNA damage, cell damage, muscle atrophy, bone loss, decreased muscle mass, and joints worn out from overuse during a lifetime of bipedal locomotion. It might have worked great for prehistoric humans, but it wreaks havoc on our knees and hips.

You will never go wrong with actually photographing process. It's primitive. Humans love to see the bipedal animal in us finish things. We just like it!

You don't just magically flip some evolutionary switch somewhere and transmute a quadruped into an upright-walking bipedal human.

Often used in biology or paleontology when discussing the evolution from four-legged to two-legged movement.

Evolutionary Term

Although humans are bipedal, some animals like birds or kangaroos also walk on two legs.

Not Just Humans

In robotics, 'bipedal' describes robots designed to mimic two-legged human walking.

 two legs and catches the fall so that's how it walks but when you look at us human being bipedal walking what you're doing is you're not really using a muscle to lift your leg and do like and walk like a robot right what you're doing is you really swing your leg and catch the ball stand up again swing your leg and cast a fall you're using your

They say, "Why model just in the sagittal plane or the vertical plane, when you're telling us these animals are moving in the horizontal plane?" This is a good question.

 I'm actually standing far too close. A chimpanzee is far stronger than I am, and I just was not very prudent, this particular video. So what you saw him do is he was lifting himself up and standing on two legs, and putting his arms out. That's called the bipedal swagger.

The surprising science...

 he came up with a hypothesis that birds descended from small bipedal dinosaurs. But other scientists opposed this idea because they said, well, you know, all birds have a wishbone, right? This is not known in any dinosaurs. So birds can't be living dinosaurs.

 Like their ancient brethren australopithecines had some ape-like traits. However changes in the skull, spine and legs indicate a notable shift toward a very human-like trait. Consistent bipedal locomotion.
