How we ended up on two legs? Evolution of bipedalism

How and when did the human bipedality started to become what it is today? Why we are bipedal? This 2 minutes clip is aimed to answer these questions.

One of the most complicated scientific concepts (with literally thousands of books and articles are dedicated to it) is explained in simple terms. The general understanding of this topic will facilitate a further detailed familiarization with this subject.

very interesting its good that this channel exist it fights primitive myths

[warrendourond]

I really like your videos... this one however seemed to be a little too certain about many aspects of our evolution that are still very speculative. The fact that we are less hairy than our primate relatives has many plausible explanations and is likely to be a combination of several. Even the idea of when our lineage developed bipedalism, is up for some debate. And without knowing exactly the conditions under which this occurred, you can’t possibly guess as to why. The transition into a savanna environment is certainly the leading theory, but it isn’t the only one. And it only leads because it best explains the minimal evidence we have today. I personally like a moderate version of the aquatic ape theory, where we descend from a lineage of ape that carved out a niche exploiting tidal and shoreline resources. However I would never claim the case for this theory is so solid as to refute all others. What separates us from those that believe, is a certainty that closes the mind to contrary evidence. I’d hope a channel devoted to dispelling myth, would be mindful of the ways in which myths begin.

this is one of the most beautiful videos I've seen so far this year.❤

When they came down from the trees our ancestors were already accomplished bipeds. They exapted a lot of arboreal traits for obligate terrestrial bipedalism. We still have those arboreal traits eg pincer grip. And that muscle in forearm that lets us brachiate should we choose to do so

Oh wow thx I didn’t understand before!!! Thisis so interestinggg!!!

It's crazy to think that when our ancestors were australopithecines, we were basically tasty snacks for a lot of critters that are now long extinct. Life would of been so hard..and probably very short.

U r explanation is good with good animation

an animal climbing the trees in an upright position? I can't imagine that. has the name of any species?

WHAT IS THE FUNDAMENTAL EVOLUTIONARY ADVANTAGE OR IMPORTANCE OF BIPEDALISM:

You all missed the fundamental point regarding bipedalism. THOUGHT, emotion, AND feeling are INTERACTIVE. Consider what is a dog or a pig, for example. It's heart is inside it's head. It is the differentiation of THOUGHT in RELATION to emotion AND FEELING that is fundamental ON BALANCE. Indeed, it is a very great truth that THE SELF represents, FORMS, and experiences a COMPREHENSIVE approximation of experience in general by combining conscious and unconscious experience. Sleeping includes dream EXPERIENCE. Consider the body position. The Common Chimpanzee is BETWEEN our dream experience AND our wakeful experience. Consider their much reduced habitat/experience IN GENERAL. For example, ON BALANCE, consider what is their SIGNIFICANTLY reduced experience of pain. Now, consider what is upright waking. INDEED, the Common Chimpanzee lives exactly TWO THIRDS as long as we do (COMPARATIVELY that is, meaning in captivity, of course). In fact, we spend about ONE THIRD of our lives sleeping. Great. ACCORDINGLY, ON BALANCE, consider knuckle walking AND their overall body posture (and/or bodily positioning) with regard to what is BASICALLY a 45 degree angle. GREAT. IMPORTANTLY, the INTEGRATED EXTENSIVENESS of thought AND description is improved in the truly superior mind !!

many savanna animals have fur. why only our ancestors lost it?

[markward]

This is oversimplified and deceptive. Most of these things are viewing tiny bits of information from the past and comparing it with current examples; then adding speculation and fanciful presentation. Examples:

1) how bipedalism developed is unknown and all theories have proven weak inferences, untestable or not plausible

2) allegedly becoming mostly hairless (exactly like number 1)

3) How, why and when we spread throughout this planet.

Think about this : what percentage of specimens from past populations do we have? Less than .0001 (repeating a lot)%
What can we really tell from a handful of most groups ? Yes 🧬 DNA, amazing field but there is a lot we don't know about DNA/RNA. Remember the arrogant label junk DNA, later so said junk DNA is functional. WAIT ...I am not telling you what to belief just being critical as science suggests. There are other ways to look at this information. Best to you. Keep learning. Be well.

It seems disingenuous to call yourself “Scientists against Myths” when what you have presented here is in itself a myth. As I am sure you are aware, there are multiple theories about how this happened and there is still an ongoing debate (Wikipedia lists 12). Why not start this by saying, “Nobody knows, but here is one possible explanation”?
