Great Transitions: The Origin of Humans - HHMI BioInteractive Video
HTML-код
- Опубликовано: 27 сен 2024
- Which traits distinguish humans from other primates? When and where did these traits evolve? Discover the latest findings on hominid evolution in this classroom-ready biology video.
Paleontologists have studied the fossil record of human evolution just like they have done for other major transitions, including the evolution of tetrapods from fish and the evolution of birds from dinosaurs. In this film, part of the Great Transitions trilogy, Sean Carroll and Tim White focus on the evolution of three traits: larger brains, tool use, and bipedality.

A wealth of new knowledge. As it nears midnight & bedtime, I will sleep dreaming of being a paleontologist. I have the greatest respect for people who put in the long hours, days, weeks, months & years to provide mankind with knowledge of the past.
What always seems to get overlooked and underappreciated in most of these discussions is that it is very likely our ancestors, since apes, have been making and using tools (mostly bone and wood) - just not making stone tools which according to recent discoveries may go back 3.3 million years.
Do not forget one of the most useful tools: ropes. Unfortunately, the very nature of ropes (probably vegetable fibers and maybe sinew) prevents their preservation across millions of years. But I'm pretty sure they were used by pre-humans, otherwise our human children wouldn't be able to learn to lace their shoes so easily. I still expect some fossil record of rope imprints in fossil ground will someday show up.
Stanley Kubrick seems to have speculated about that at the beginning of 2001: A Space Odyssey.

I remember being an 11 year old asking my mum to please buy me the book with the strange human like apes in it. Then it was quit difficult to understand but it blew me away. In school we had religion class with God creating everything and here I had this wonderful book that said something totally different. It made me think and go look for other books about fossils. A whole new world opened up for me. I may say that I was a dinosaur enthusiast long before Jurassic Park. I’m so glad that my mother bought that book so many years ago, it changed my way of thinking and made me look with awe at the natural world.
Millions of years ago monkeys existed and still exist. If human is evolved from monkeys where r the intermediate apes now.
Dear these r just theories supported by incomplete evidences.
@@MuhammadAsif-blue Misunderstandings all around so let me set you straight.
1. Humans evolved from apes and still are apes.
2. Other primates still exist today because they fill a niche in an environment.
3. Progression through evolution occurs through trial and error, not linearly. Causing species to *branch* out from one another.
4. Intermediate species between Humans and our last common ancestor with the Genus Pan died out from error.
That is why we must keep religion out of common education . Religion is wholly incompatible with reaon and reality .
Think of it this way: Let's say your great-grandfather was a farmer. He had two kids, one of whom stayed on the farm, and the other moved to the city and became a factory worker. Fast forward to the present, you're working in the factory like your grandparents, and your second cousin still works the old farm. But your mutual great-grandfather is long dead.
Muhammad Asif You have absolutely no clue. Your inability to understand evolution is not evidence against it.

Our species is just amazing. The fact that we can know anything about this universe makes our arrangement of atoms special.
There is no "arrangement" to our atoms. That would require an arranger. Our atoms just luckily got that way by accident. Pure 100% luck. They just defied entropy and got that way, arranging themselves. Scientists can prove it using the scientific method. Honest, just ask them.

Honest information is amazing and beautiful but, sometimes rare where paleontology is concerned. Worship and slavish adherence to Darwin has polluted all of the science. Carl Sagan was being honest when he said the belief in evolution originated in ancient Paganism. Honesty is hard to come by these days.
I was really moved seeing how excited everyone involved in these discoveries were, even just revisiting the memories of making the discoveries!
Glad you enjoyed it!
We really have come so far in the nearly 70 years since Louis and Mary Leakey made their first discoveries.

Lol, look up Darwin's study of barnacles... just barnacles.
In my graduate research from about 20 years ago, I concluded that bipedality first emerged in an arboreal environment. Nobody I told this to at the time gave my hypothesis much credence, but I knew I was right, partly because I found the savanna hypothesis to be unworkable. One also needs to bear in mind that the old growth forest environment back then contained trees with horizontal branch runs that were large enough for hominins to transverse easily bipedally where they could stabilize themselves by reaching out - brachiating - for balance, the way present day orangs and gibbons do. Thus, bipedality emerged not as a primary, but as a secondary trait, a trait that was just what the species needed when the Savannah grasslands began to emerge.
I totally agree with you. Bipedality must have originated first when our ancient ancestors were still forest dwellers, I still thinking about what the advantages would have been, maybe you can give me your thoughts on that.
Cannot wait to find more about our origins
I really enjoy the videos that hhmi posts. Always worthwhile to watch.
Thanks, Howard
It is amazing how all those fossils from different geological epochs are so easily found on the surface today!
I don't know how easy they are to find, but if you're wondering how they get to the surface, the answer is weathering.
Paul Millbank While weathering plays a roll, uplift plays a bigger part. Older layers of strata are brought to the surface in anticlines cause by compressional forces exerted onto them.
People have been looking for 100 years. Defo not easy.

Not "someone" but either everyone or no one.

@@jasonmathias5343 Pretty much the case, I was going to say the same thing.
What makes us human is our brain. The evolution of the brain is the key. I'm no scientist but it seems to me the evolution of the brain triggered with emerging from the deep jungle. In the jungle the sense of sight was only useful at very close distance. By the time you saw a predator it was too late. As the jungle shrank eyesight became more useful and the pre-humans began to stand up on to feet to look over tall grass and further.
As they did this they began to "think" about what they saw. They couldn't smell or hear it but they "learned" about what they saw. This led to reason, predicting the movement of a prey or predator. They probably lived largely on insects and seeds easily obtainable. When they saw grass moving abnormally they learned it was a hoard of grasshoppers and they would gorge themselves on them and recognize from a distance a patch of berries or other food sources.
The wider open the plains became the more useful eyesight. The more they used eyesight the more thy used their brain to think about what they saw. The eyes and brain evolved together. In later times they would see quarry, deer for example, and predict where they might intercept them and develop sophisticated hunting strategy. Thinking became more and more useful. Keenest eyesight and biggest brains were the "fittest" and it probably really accelerated compared to pelvises and such.
Very well made documentary. Although more recent evidence has shown Australopithecus could make a few simple stone tools.
And I have heard recent lectures that maintain that chimps are tool users, and even that the common ancestor from which our line and chimps both descended used stone tools. Of course we know that crows, and monkeys use stones as tools. Maybe the real distinction is in crafting tools rather than using found stones, or simply breaking bigger stones into smaller ones.
please, not this again. crows use tool ffs. the point is no other species uses tools to the extent that humans do.
@@bobaldo2339 Actually, chimps MAKE tools: they strip the leaves from small branches so they can probe termite holes to bring termites out that then they eat

0:31 what is the criteria for characterizing humans as having big brains?
Adrian Dane Kenny bigger skull
I may be mistaken but I believe it is based on the size of the brain in relation to the size of the body. An elephant has aa much bigger brain overall but in comparison to the size of their body this isn't so. It takes more brain matter to be used to make a bigger body simply function (as opposed to being used for higher thinking) to live [heart beat, breathe, etc.] than it does for a smaller body. So the bigger the brain in relation to body size, the more of that brain can be put to other uses such as higher cognitive thinking other than functions necessary for just survival only. I'm no expert on the matter but I believe this is at least part of the answer.
Thanks
These finds are amazing but I do worry that some of them might just be extinct primates not along our lineage at all. I can see how some of these early discoverers might wish their discoveries to be hominid and therefore interpret them as such with a little bias. Like Lucy's pelvis. Still amazing finds.

WRONG, wrong, wrong. There is no transition from Apes to humans. Humans ARE apes. We did not 'became' human, human is a sub category of apes, not something different from apes.
goognam goognws what the hell are you talking about. Of course we evolved from apes, specifically chimpanzee. We evolved and became bipedal and with that other characteristic. We are not a sub category we are a new category, bipedal primates.
Chromosome 2 is a fused chromosome which could point to the transition when and how this happened is a question I would like to ask.
ACTUALLY, there was 7 million years of hominid evolution, a very diverse species of dozens of subspecies, suddenly and abruptly Homo Sapiens appear 100-200 thousand years ago and within a few thousand years 7 million years of evolution go extinct. Homo Sapiens emigrated within a 50,000 year time frame and dominated. All living humans are Homo Sapiens. Not only did they extinct all known hominids but they bypass Old World and move to North America and Australia. A new species that appears spontaneously and immediately dominated and expanded beyond what was thought possible. Dozens of known hominid species that developed independently went extinct apon the arrival of Homo Sapiens. Current DNA shows that there is no known interbreeding but that is contested, it was previously thought 1-4% of European DNA had Neandertal origins but since that early analysis it is believed that infact they were different species that share no ancestry. Hominids at the height of evolution had huts and spears/stone tools and unlike their ancestors had rudimentary vocal abilities. Once Homo Sapiens appeared new development of complex language, written language, bronze, iron age, and civilization presented within a few thousand years.
WE are humans, you are an ape...

The videos on this channel all have the same top comment.
At least once, now we can tell, that higher social order among living beings has lead to the planets. We can also tell now that evolution can be so capricious as to reveal its arbitrary nature. But we are sure from long, horrible experience how our species reveals terrible, self-destructive tendencies.
The time that homo sapiens exists is to short to learn how to behave in a very complex world created by man himself. The 2 world wars, the creation of the nuclear bomb and the accelerating increase of the destruction of our environmental nature show that we are learning much slower than we create new dangerous things. If we cannot learn to better slow down development to a degree we can cope with we are in danger that this will be our last century and all the millions of years of evolving mankind were in vain.
cool stuff!

Anthropologists get funding to "discover" what those people who pay the funding for results or the funding dries up.
How do they know they were hairy?
I don't think they do know. Its kinda hard to tell when hair disappeared, since its not in the fossils. The only real evidence for when hair dissapeared(that I have found) is from genetic testing of lice. But, it is also reasonable to assume that we lost our hair when we started wearing cloths, and that we started wearing cloths around the same time we started using tools.
We are one of the very few animals that has evolved beyond the need for fur, due to our ability to make clothing.
they way ancient humans hunted was chasing down prey to exhaustion, known as persistence hunting. A hairy creature can not keep itself cool long enough to do this, so we know that when there is evidence of humans hunting regularly, then they must be hairless, or at least significantly less hairy than ancient ape ancestors
@@jesustheillusionist6484
We started making clothing out of necessity. The cold snaps of the Ice Age must have been intolerable to the relatively hairless human body. It shouldn't take any great leap of the imagination to realize that some of the brighter Neanderthal and Cro-Magnon individuals hit upon the idea of covering their bodies with cured animal hides as protection from the cold.
@Dan C. Agreed. Through the vast history of mankind, only the strongest and smartest survived to reproduce. Now, the weak and lower IQ people are reproducing at a much greater rate. Our future is questionable.
Tool use for australopithecus HAS been found since the making of this video.
Depends on what you mean by _Australopithecus_ as that's an entire genus. In the video, I'm fairly certain they were referring to _Australopithecus afarensis_ which at the present moment no tools have been found on their part, however, the oldest Oldowan tools are dated at 3.3 million years old, and have been shown to have belonged to _Australopithecus africanus_ which some palaeoanthropologists believe to be the same species as _Homo habilis_ also known as the 'Handy Man'. However, _Australopithecus africanus_ started making tools around the time that _Australopithecus afarensis_ was still around, as they seem to overlap between the 3.3mya and 2.95mya mark.
Whales have big brains,kangaroos walk on two legs and crows make tools.
The first humans were created when logic and elaborate speech were created.
No offence to the apes.
So the transition is not biological but spiritual.
What's so 'spiritual' about logic and speech?
Whales have relatively smaller brains, Kangaroos walk on 4 legs and hope on 2, and Crows use tools, they do not make tools.
Apes today have elaborate speech, they are still apes.
The biological transition leads to the spiritual transition, if you wish.
No....the transition is physical...at first anyway. You named 3 species which each have one of these traits...not another species which has all 3 of these traits at once. Also "big brains" doesn't necessarily mean overall size period. In this case, I'm pretty sure "big brains" means brain:body size ratio...which would show that humans by far have "bigger" brains than whales.
@@halwag What is so spiritual about speech and logic is that they are both used to avoid violence one reason I can think off.
Thus they are used for a higher cause.
@@craigslattery1901 Whales indeed have RELATIVELY smaller brains but still a hundred times bigger if you put them next to human brains.
Humans crowl on 4 legs hope on 2 and hang from their hands.
Kangaroos walk on 4 legs and hope on 2 indeed but they can also box with their hands.
Apes have elaborate speech and dolphins even more elaborate.
What I'm trying to say is that "reasoning" divides humans from animals.
Now reasoning seems to coinside with humans' highest biological level
but that doesn't prove that it was derived from evolving.
That footprint on the cooled ash layer at 10:36 appears to not require a size 7.5 footwear .

@@jackmack1061 Nowhere in any genesis story does it say the earth is 6000 years old. Even in the oldest Biblical texts, it says the world was recycled from old creatures before that were destroyed in the flood. It only presumes that the modern human race that is technologically advanced is about 6000 years ago, which by all means, our history and archaeology proves this.
I cannot explain the evolution of the brain at all. Why has it evolved so far? It is an unusual evolution.
@Dan C. Why? It's basically just duplication mutations, with further mutations modifying them. It's not impossible by evolution, not by a long shot.
And the brain didn't develop from bacteria, the first nervous system which accumulated in the head later on mostly appeared far later. Now that did develop from single-celled then multicelluar life.
@Dan C. if its myth how the science has so many proofs and facts
Dan C. God is a myth along with all those bedtime story characters like Moses, Jesus, Mohammed, etc. There's plenty of evolutionary evidence which you choose to ignore.
