The 'running ape' . Sprinting is a great way to avoid predators but 'Seeing' the predator first is paramount. In all the suggestions of the reason for bipedalism in apes I have never heard mentioned the fact that an upright posture makes it easier to turn the whole torso, and then the neck , to look behind and scan the area (pretty much like meerkats) for predators. So this may be another contributing factor...along with wading in water, and carrying things, heat...etc

This is part of what's been leading more and more people to consider that some level of bipedalism may be the ancestral trait of apes and that we are the only ones who retained it.

There is a book I have somewhere regarding tool use by animals. it is fairly common for animals to use tools but this book states that all the tool uses are opportunistic whereas humans are more future visionary regarding making tools from raw ingredients. Communication and learning just got stronger and stronger over time as we developed. By communication we made tools better over time.

@cubearthx Жыл бұрын

It isn't just the tool usage that is incredible but how many generations of our evolutionary line have been slowly and painstakingly fighting to overcome the limitations of our physical biology and the natural world (although we are part of the natural world). It's humbling and sad that they never got to see what we have achieved from their humble beginnings. Also to imagine how puzzled and afraid they must have been to have limited intelligence (and I'll assume consciousness) trying to figure out the world they have been thrown into and the possibility that my consciousness could have instantiated at any point in the 3myr lineage. Damn, I'm grateful to live here and now when we have a good foundational understanding of our origins and our place in the universe.

I much appreciate your videos for how easy they're to understand. I'm from East Germany, and so, I was taught by teachers, who had actually studied Russian and had either studied English only as a minor subject without passion or only later had English as a further education, for the most of my school time. Just in the last 3 years, I got a teacher who only studied Russian to be allowed to study English. This is why I'm struggling with English, but some creators like you make it so easy that often when I wanna share it with other people, I stopped for a moment because I'm not sure if they understand it, too. Sometimes, I wanna share it with people who may not understand Englisch, and then, I realize I totally forgot it was English content. Sometimes, I wanna share it with English speaking people, and my first thought is that it would be dumb to share German content. So, try to imagine exactly what I saw and heard, and this is the point when I realize the magic. I remember the complete side, even the advertising at the borders. I remember the text, not in English but in German. I remember the voice in the video, even yours, but they don't speak English in my head, but German. So, I go back, and I am confused by realizing it never was on German. This is every time again when I stop thinking it only could be German because I didn't struggle to understand it, and start thinking I'm not that bad in English as I think. The problem is rather that I built up a barrier every time when I'm forced to speak or understand English because I wanna stay in my comfort zone. I really appreciate this because this is a source of motivation to practice English, which is something I completely missed in my entire school life. I'm on the one hand sad about to have missed so much over these years, but I'm much more happy about to enjoy another cool language and so much more interesting stuff now. So, thank you so much for your work! 🥹

Gutsick gibbon has mentioned in a few videos how there are "languages" that exist in other primates. I can't remember which one specifically, but there was an alarm call for danger, then another as a modifier for location. It's not as developed/massive as ours, but also doesn't need to be. And without a cultural context, apes using sign language may be using is differently than we would expect, but makes perfect sense to them. There's an island that doesn't differentiate between animals like most other places, it's either a sea creature or a land creature. Word order could imply emphasis. _I_ never said that. I never _said_ that. It's also difficult to know if they understand the word the same way we do. When you're teaching a dog "potty" but you say it when you are letting them out into the yard, you can't be sure they understand it as anything other than being let out into the yard.

The fact that modern humans as a species have existed for more than 150,000 years really puts in perspective the timescale of the progress of evolution. The first civilizations only appeared a couple thousand years ago. For me it is fascinating to think about how we will at some point have become a new different species I don't understand why so many people got triggered because I said "a couple thousand years ago". I obviously did not mean just 2000 years (look at my damn username lol). So, for all the people that chose do ignore my point and focus on this, let me at least make it clear: The earliest civilization is thought to be Mesopotamia which is estimated to have formed in 5000BC so 7000 thousand years ago. Going back to my point, 7000 is not a lot compared to 150000 years!! (Pollock, Susan, and Pollock Susan. Ancient mesopotamia. Vol. 1. Cambridge University Press, 1999.)

@@rafaelverolla7276 The predominant theory I was taught was that as the forests in parts of Africa started thinning and changing into grasslands, the primates had to come down from the trees and make their way across the open spaces to find other food sources. Those that could stand more fully erect above the tops of the tall grasses for longer periods of time were able to spot danger in the area from further away, thus giving more time to reach the safety of a tree and ultimately, more of a lifespan to pass on their genes. I don't recall the narrator mentioning that in this presentation.

This video uncritically repeats the Rubric that the 'arch' found in the human foot evolved to serve as a "shock-absorber...since the foot is supporting So Much Of the body's weight."(t=10:30sec~10:40sec). 2nd claim first; when we're standing unaided (not holding- & leaning on a cane, etc.) 100% (NOT 'much') of our bodyweight is borne by the structures of our feet. As for the 'arch' claim, the animation showing central loading is deceptive; when stationary, our ankles joint to the heels BEHIND the 'arch' -- gaining ZERO 'shock absorption' from the arch. And arches are also present in the feet of apes - helping the foot curve-'round/conform to features grasped by the opposed big toe.

My readings into this subject indicate the ancestors of Australopithecus were most likely Shore-Based, in which case, they would have walked through shallow ponds / rivers, which in turn would have reduced the weight on their hips... which would have allowed them to walk upright for longer periods. Generations upon Generations of this behaviour would have pre-selected for more appropriate hips, to extend the amount of time walking upright in the water that was possible. This then would have translated to walking on dry land too. For example, Chimps can walk upright now, on dry land, but not for very long, since their hips are not designed for that; but when they walk through water, they can walk upright for a much longer time, before it starts to hurt. Trouble is they rarely walk through water, so there's no evolutionary pressure for their hips to change. If the ancestors of Australopithecus were indeed shore based, they may have been gathering mollusks for food, which would have provided them with more DHA-Omega3, which would have been another first step to increasing the brain size. With the Hips now evolved for better upright walking, the foot was now in a better position to start evolving for larger weight too, but also for fore-foot running. And when we started to do Persistent Hunts, the long distance running had the benefit of producing Brain Derived Neurotrophic Factor (BDNF), which also would have had a positive influence on increasing our brain size. There's also the thinking that mushrooms additionally played a big role in creating new connections within the brain, i.e. the stoned ape hypothesis.

Seeing as walking seemingly developed before bigger brains, this logic would conclude tool use had nothing to do with walking.

Not only Koko, but Washoe, the chimp taught ASL, would also lie and make spontaneous sign combos to describe new things.

@DruNature Жыл бұрын

cause they didn't actually know ASL and it was all interpreted by the human, doing so to promote their belief. Gorilla sign language has been disproven unfortunately, or it could be scientifically verified if true.

huh... how does being bipedal lead to less energy expenditure? i would've thought that supporting a body on 4 legs is more stable, more passive

@astrophysicslair1445 Жыл бұрын

I believe the basic idea is that it takes less energy to move two legs than four. I'd imagine it's a more complex answer though.

@tylercoleman9218 Жыл бұрын

The energy saved by walking on 2 legs is minuscule but every calorie saved counts when it comes to survival. Consider just the energy exerted from the movement of leg muscles alone and then imagine having an extra pair of appendages constantly exerting energy to facilitate movement. While quadrupedal stability does save some energy it doesn’t beat bipedal locomotion.

Bipedalism can be much more efficient if done right. But it also has other advantages. It frees up your hands for tools and lets you see farther because your head is higher up.

On 2 legs you "fall" into your next step, this means gravity helps you. It is one of the reasons going uphill is so much harder than walking on the flat.

its not that its bad hypothesis, its just that there isnt any evidence to support it, and it is designed in a way that its not disprovable. i think we were bipedal while we were still on a trees.

@sturlamolden Жыл бұрын

Bipedalism in humans need no explanation. Take our most distant relative among the apes, put it on the ground, and see how it walks. You can find videos of this on KZfaq. Spoiler alert: It walks upright like humans. It does not knuckle walk like chimpanzees. We walk upright because we retain the gait of the common ancestor of all apes. We do not need a special theory to explain how bipedalism evolved. just pick a gibbon down from its tree, put it on the ground, and see what it does. We were bipedal before we came down from the trees. Rather, it is the other great apes that has evolved a new quadripedal gait.

I had a consignment of natural slates from India, finest qualiry imagineable, and a lot of them had humanoid 3 dimensional footprints in them, Identical to the modern Human foot. my feet, size 43 european, or 8 and a half in other measures, fitted perfectly into both the left and right footprints. so fine, it must have been like waklking in talcum powder an inch to two inches deep. You could even tell thatvthe toenails were neatly trimmedvor manicured, and that there was no hair on the sides of the feet, each print had the triangular scuff mark behind the heel, that we get when strolling on damp sand at the beach. The Slate Seams these slates were cut from, apparently are aboutv65 million years old. The Slates were a nice silvery grey metallic colour, so the quarry should be easy to track down, andcthe number of footprints in three crates of slates were so numerous, they must be very common in that quarry. I showed them around local friends and neighbours , and left some at the local Museum with my business Card, but they never got back to me. Best Wishes. Bob in Wales. 👍

A bi product of bipedalism could also have been that it allowed the hands to become more dexterous and useful for the development of better tools and tool use. Hands and brain development are inter dependent. The complexity of hand function as an extension of the brain’s ability to express itself is orders of magnitude stronger than the brain and the feet, for instance. So bipedalism freed up the hands to become ever more useful and the Brain took full advantage of that.

10:52 K-Ar dating is wildly unreliable... The decay can sometimes be slowed or accelerated by environmental conditions (which normally isn't that big of a deal to get a ballpark idea of age), but the really big flaw come from the starting assumptions of how much K-Ar was in the rock at the time of solidification... Whenever K-Ar is tested on rocks of a known age (like Mt. St. Helens or Mauna Loa) it almost NEVER returns the correct date. So how can you trust something to produce reliable results for millions of years in the past, that you know fails to return the known correct answers in the present???
