After 50 years, Lucy faces rivals with other human ancestors

- In 1974, paleoanthropologist Don Johanson and student Tom Gray unearthed a 40% complete skeleton of an early human ancestor, fundamentally changing the human family tree. The specimen acquired a nickname that persisted: Lucy, after the Beatles song playing at the fossil hunter’s camp--“Lucy in the Sky with Diamonds.” At 3.2 million years old, some thought her species, Australopithecus afarensis, was close to when the ancestor of humans had split from the ancestor of chimpanzees. But in the past 50 years, discoveries of hominins both older and the same age as Lucy have pushed that split millions of years deeper in time, and challenged her position as mother of us all.
Read the story: www.science.or...
I have loved Lucy and her ever evolving story since I was a child. The representation of her is so lovely.
I was astonished to see one of the ancient skulls in this video looks like the map of Africa! How cool is that?
This is great, the journey of discovery to our origins. Hope future discoveries and new techniques will help to get a better picture.
I said, to my late partner, over ten years ago, "you know, the next ten years will reveal a plethora of human ancestors that I would estimate to go back around 10 million years to our first common ancestor! The start of a golden age of simeons, so to speak"! Time has rewarded me, thank you to all those who spend time and effort in this fascinating field!
What made you think this, please?
That is à beautiful comment.
...and my greatest regret !
After having followed the discoverings in this field, I regret not to be able to live long enough to see the answers to all those questions. 😊
@@bastiennietveld7128 Same here. I may be round for a few more revelations, but not the whole story.
It's good to see Lucy. I saw her in the 70s at The Museum Of Natural History in NYC when I was a kid.
@@JesusisLOVEJohn- Oh, here we go....
@@MattTee1975 Go?
@jeanettemarkley7299 - I saw her there, too. I remember the long line waiting to see her and how I got tears in my eyes.
@@MossyMozart I don't remember lines, but I may have went on a weeknight with my aunt who took me places whenever. I was very young when I saw her but I had watched her on TV and knew what she was.
could we extract DNA from Lucy and then mix it with modern human?
I love that African archaeologists, anthropologists, and other people in the related fields are finally leading excavations and research on the finds in their backyards, so to speak. It's absolutely fascinating, all the species that have come and gone from the primate family tree and what we can learn now from the tiniest samples of their teeth or burial soil.

I knew and saw pictures of LUCY few decades ago. But this piece of report is so good that I seem to discover her importance anew. I have an affiliation with her as I am descended from people from this region who travelled to India and composed of the largest group of homo sapiens in the world called Australopithecus. She isn't just my mother, she is the most beautiful mother I now know. Thank you SM.
Bipedalism doesn't necessarily indicate a "branching away" from the common ancestor of other modern apes. Recent studies have suggested that the knuckle walking found in chimpanzees and gorillas may have developed since the common ancestor of them and humans. It could be that the common ancestor was in fact bipedal and that the other great apes developed their means of locomotion based on evolutionary requirements that meant that bipedalism was a disadvantage. I will admit that this seems unlikely but it is not impossible.
i thought this was now the main idea
Me too. It sounded as if it were the new consense.
There was video showing a chimpanzee carrying her baby, wading through water quite comfortably upright on two legs
I mean it wouldn't be that weird, I'm almost certain there are examples of exactly the same in other scenarios in the tree of life.
I'm talking about winning a trait and then losing it of course.
Lucy, thank you for coming down from the sky and gracing us with diamonds
@user-is8jw5lc6n - Yes. It is possible that she is a grandmother of us all.
i can remember scouring my high school library for all of the books they had on human evolution >20 years ago & i am absolutely astonished at how much more we know today
No one ever thought the Taung child ( juvenile Australopithecus africanus)was “an early baboon.” Where did that come from? It was considered a very primitive hominid from the start, by its discoverer, Raymond Dart.
First I've heard of that take too.
I just heard that recently in another video.
I think what the presenters were saying is that some of Dart's detractors argued that it might be a baboon specimen, not that the discoverer himself thought so.
Other anthropologists were saying that for 20 years. ......... It was a long time before they accepted that Dart was right.
0:00 Haha i love how narrator woman's last name is Gibbons like the ape, it's fits well the subject of the video about Lucy who is our ape-looking hominin ancestor
Drives me crazy that they say things like “our ape-like” or “ape-looking” ancestors. They were apes and we ARE apes now. Hairless, bipedal apes with language. The fact that scientists use this “us and them” language is maddening.
So this is mother? Kidding of course but certainly a good reference
I remember reading about Lucy in National Geographic. I was a teenager!
Subbed - this is wonderful!!!
Its a amazing how a skeleton was lying there untouched for three million years…
If we are made in gods image then that would mean he is an ape. Me King Kong in the movies must be god right I mean he is the strongest and biggest ape.
I agree 👍 , god is the king of all kongs. Wiser than a kingkong.
It's not god's image.
@NalaRichenbach You're right, it's not. It's a joke... and apparently, you missed it. I could say more than that but it wouldn't do any good.
Wow! This is awesome! Thank you for informing us non-scientist but very curious people!!!!!!
I don’t think creationists deserve a voice.
Yeah, fragile ideologies must be protected by suppressing opposition.
@@TexasHoosier3118 none of you have any actual arguments though because a religious belief has nothing to argue with
Well done coverage. Exciting ongoing story of us. Great to see African nations developing that story. Can’t wait for more!
It's always interesting to see challenges. Scientists should always challenge themselves to ensure the best outcome.
Without bias or perceived notions.
@@nialccyeah that's science buddy
@jeffpittman8725 - They do for the hugest part. And if somebody gets something wrong, another researcher will eventually set things right. Science is self-correcting!
(Please don't mention so-called Piltdown man. The person who perpetrated that fraud was not a scientist, but an amateur hungry for acclaim. It was recognized as a fraud by real scientists almost immediately, but took some others a while to catch up. it turned out that the fraudster's other great discoveries were also faked.)
This is so awesome.
I love the way the subject has grown since the 70s Our understanding of human evolution has advanced by leaps and bounds and I so envy younger people coming in to the science now.
Maybe I'm a bit sentimental....But sometimes I think of all these races that gone extinguished....
And I imagine the last old woman or man of their race.
😢
A bit like the mammoth in 'Ice Age' . 😂
6:55 Thinking drones with right software is the answer here.
Mother was ripped!
Too long winded and chatty and too little information, not at all systematically presented. I'm not interested in listening to you all blow your horns with egomaniacal stories about your findings. I wanted a systematic presentation of the earliest hominids. I can't even follow this.
I was lucky enough as a teenager to actually see Lucy's fossils at a gem and mineral show back in the early 1980's along with the famous crystal skull in Detroit.
I was awestruck and it gave me a deeper respect for science.
I do not miss that thick and dark fur, unlike how light and fine it now is. I do not miss being that petite. I do not miss the forward-facing nostrils. I do not miss that smaller brain. But I *_DO_* wish that I had Lucy's fabulous cheekbones!
I wonder what it would be like to meet one of these creatures. How would they think and react to us.
They would probably be rightly terrified, or at least wary.
They would probably kill and eat us.
I love the Ethiopian name dr Johansen though of but I guess Lucy in the sky with diamond just got stuck in our minds - she was a gift like diamonds - greetings from South Africa
Right On Great Video
Cool! Her name is Gibbons.
I'll come back later to see the comments of the creationists.
face-orange-raised-eyebrow 9:49 GOOGLE :
" Baboon bone found in famous Lucy skeleton "
Do not be ignorant, the focus of creationists' attention is on the first cell and how it originated
Not unlikely that if asked a dei-related question you will spit out creationist views.
What does this video have to do with creationists?
@blacksilver9542 creationists think this is fake, that man was created as is, no evolution, Earth is only 30, 000 yrs old. Prehistoric fossils are a lie created by Satan to deceive. Most creationist vote for Trump.
*Has the possibility of these species being our cousins, rather than direct ancestors, been considered?* Maybe we’re on different branches.
Yes
Of course!
We must honor Lucy. we are Humans. Lucy is an early Part of Homo - of Humanity. Lucy is a mother of us all.
She died as an adult, so she could be our grandmother. ^_^
Interesting how Lucy has to be the most studied pile of bone chips in history and most papers summarize that it had a bone structure very similiar to a chimpanzee.
Why even with all the speculation and study of Lucy , the "Experts " lacked the expertise to differentiate a baboon's vetibrate from the rest of spine.
@geobla6600 - The base of Lucy's skull (specifically, the placement of her _foramen magnum_ ), the shape of her pelvis, the shape of her hips and knees, and the shape of the feet of other _Australopiths_ (the feet and hands of Lucy herself were lost to time) all *belie* your _"similar to Chimpanzee"_ comment
@@MossyMozart Are you referring to the babon vertebrae which was the basis of claim that Lucy and vehemently argued as proof of its bipedalism. At least that was better then the 100' s if not 1000's of papers and articles making grandoise claims based on the partial hip and heal bones that you rightly claimed as unsuitable
for making such claims.
Although the largest part of the specimen was the rib cage and its arms which are undeniably very similar to
chimpanzees and designed for climbing and walking on.
It's amazing how such extravagant conclusions are made from such bias and unsupported speculations ?
These guys always ~never remember that a set of foot prints, size ~7 and shaped just like our feet today, was found and dated 500 thousand yrs older than Lucy. These prints do not fit their story so they do not mention them in most cases.
Amazing how the artist was able to conclude Lucy had human feet when no foot bones were found. The problems with with using Lucy as evidence for evolution grow in number with time. Read, Bones of Contention Controversies in the Search for Human Origins.
@jaysonstirrup1416 - I suggest that you do more research into Lucy to see where you are wrong. Lucy is an _Australopithecus afarensis_ whose fossilized skeleton was incomplete. Fortunately, we all sport bilateral symmetry, so researchers can mirror the left and right sides of her skeleton to acheive more completeness. Unfortunately, she completely lacked hands and feet.
-----------------------
*HOWEVER,* she is _not_ the only Afarensis ever found. There are fossils of *_300 more_* that have been found. Your 'gotcha' has dissolved.
@jaysonstirrup1416 - PS: If by "human feet" you mean like us, Sapiens, then you are in error. The hands and feet of Australopithecus are on the way to becoming more Sapien, but they are not there yet. Therefore, Lucy _does NOT_ have fully Sapien feet. (This is information you can find on the 'net by searching.)
Seems like modern man is the love child of all these earlier genuses and species.
Lucy was NOT a common ancestor we shared with chimps as the video seemed to state at 8 seconds. Maybe I misunderstood. Lucy came long after our common ancestor with chimps, on another evolutionary branch that evolved into modern humans.
Please note that lucy has dark hair/fur which makes her look black but underneath that black shes Caucasian...
Where's all African.
Isn’t diversity great? Thank you for this video.
Any christian-evangelists feel the need to add some nonsense ???? 😂
The title/thumbnail is a little click-baity. Any amateur who actually reads popular science books will know that Lucy (and more broadly, Lucy's people) is probably not our "mother", but more like an aunt. That is true for any extinct species that we think of as an ancestor - whether Lucy, Tiktaalik, or Pikaia.
The thumbnail cracked me up
The use of the word "primitive" to discuss fossils older than Lucy is problematic. Also, of course there were intermediate forms between "species" like Lucy and earlier hominids. One thing evolves into another the boxes are in a way human inventions that crystalize one moment in a continuous process.
Your emotional response to a word does not change its definition.
@@AndrewJohnson-oy8oj - Many, if not most, researchers like to use the terms "base" and "derived" to designate relative differences. Base indicates traits closer to ancient and derived means closer to species as they appear today. More relative, less judgey.
I just figure out suspended animation.
She's beautiful
@carlotosoni9577,God said let there be DNA. This retired Christian minister and science buff has never seen a conflict between science and religion. They are equal branches of the tree of knowledge. Observation tells us what. Religion tells us Who. Science tells us how. Philosophy tells us why. Art marries them all together for us to feel, internalize, and express into the world.
I, for one, am excited and grateful for every new glimpse science gives us into the Divine Workshop.
This interesting video had me praying blessings on Mother Lucy's soul.
Religion tells us nothing, except to affirm the imaginative gullibility of humans.
@@TheDavidfallon I agree with you. Religion tells us nothing substantively true about the natural world, and indeed actually promotes any number of beliefs we now know to be false. I would concede that science and theism can coexist, but most of the world's surviving religions are incompatible with modern science (some exceptions include at least Buddhism and Shinto).
@@TheDavidfallon Lucy was an ape .
Not any ancestor of this non - ape human .
I am an assistant Pastor who is an anti - evolutionist .
I just have not seen one shred of evidence for evolution .
For example , Richard Dawkins is like the catcher on the losing baseball team .
He talks a good game , but never presents any evidence for evolution .
Religions make unsupported claims, and hold positions that go against the evidence.
Are you serious you don’t see a conflict between billions of years and six days?
Woman created from a man’s rib, versus evolution?
Yes, maybe your religion tells of a “who”, but that who, as far as we know is strictly Imaginary.
Other religions point to other “whos”, also without evidence.
Consider this…science shows us that consciousness is a result of physical brains. Every example we have of consciousness results from a physical brain.
Is your Who a conscious agent? This would seem to be a conflict.
Noah’s flood, and re-populating the earth after such an event, conflict with the evidence
And when you claim anything about what a God says, thinks, or wants…what you’re doing isn’t science.
And you’d never be able to demonstrate any truth to the claim.
I blame all the physicists for failing to build a time machine. All of our questions could easily be answered if we just had a time machine.
Great video. It would seem that AI and computer image processing could be used to analyze high resolution images of the land to spot potential fossils. I assume this is already being done. And please don't waste your time listening to or trying to rebut religious zealots. Focus on your work.
..it's strange that the more primitive have survived the more advanced species...I mean all of these in between species that were more advanced than apes are extinct doesn't that seem strange???
See, thats one if the issues with phrasing
Replace the words "primitive" and "advanced" with "basal"(closer to common ancestor) and ”derived"(further from common ancestor)
A good example is this: basal crocodilian ancestors tended to walk on land. Derived crocodilians tend to have aquatic adaptations
Another good example: our upright stance is more derived than our other great ape cousins and they are more basal. Just like how a tail is more basal to the common ancestor of all primates, and yet there are still monkeys
Evolution isnt some line from amoeba to scientist, its a "this is what works best in this situation and therefore will be more effectively passed on to the next generation, who will in turn increase the numbers of x adaptation that is good for this environment "
TLDR: basically every high-school science class REALLY failed at teaching evolution properly
@@krislochlan5366 so why didn't any of the quote (closer to common ancestor) survive over chimps and gorillas, did we kill them off, what happened?
@@GBucknethe environment didnt favor them, could be things changed too quickly, could be they got out competed by a relative, could be a new predator came on the scene that wiped one lineage out but another survived that due to unique traits. Lifes little dance has been going on for billions of years now with its ever complex set of steps.
The apes of today aren’t the apes of two million years ago. Modern great apes aren’t primitive, they’ve simply advanced along different line(s) than we did.
@@Darkstar-se6wc and what were the predecessors of the great apes, apparently they're were some, what happened...
Africans maybe already saw the oldest bones ever alive and just dont know it. Its their land and walk to it everyday they are the best person to encointer it whenever it appears. Soo africa will be developed and land covered in concrete the world chances of finding something significant will be less
Do you have any idea how HUGE Africa is????? "Covered with concrete........."
My mother was a mudder. My father was a mudder. . .
😂😂😂😂😂
Great video, however not including Homo Naledi in the discussion was a glaring omission
@driesvdc2 - Lucy is _millions_ of years older than the _Homo naledi._ The Naledi are practically our time-neighbors while Lucy is our long, long ago time-ancestor. So, not a glaring omission.
Lucy sounds like a person you can find anywhere at any time. It feels like you met her somehow. The Dinkanesh name would have sound like a far away myth. Being the same discovery, I like the Lucy feel.
So the founding director is called Donald johanson
And the film lucy was played by scarlett johanson
Imagine her in a Range Rover
Lucy in a car with diamonds
Like Rambo the orangutan!

Kind of sad. The old time swashbuckling adventurous explorers are gone. That's precisely what gained us all these magnificent finds in past years. Now it's more clinical. And the fossil hunters nowadays don't seem to have the same drive as theold school guys like Don Johanson, Richard Leakey, Phillip Tobias, Raymond Dart, Yves Coppens. Yes those guys were controversial, boisterous. But darn, they were good. Lee Berger may be the last remaining old school explorer and he seems to be getting pushed to the side.
They were NEVER "swash-buckling" Indiana Jones types. The people you mentioned were all out there - walking, looking and digging, digging, digging.
@@cecileroy557 Lol. You've obviously never read any of their books. Hell, Richard Leakey had to battle 20 foot crocodiles in the Omo just to get his pontoon boat to the other side with his pregnant wife on board. Johanson was an animal. He worked 18 hours a day looking for fossils, hardly ate or drank. And then there's Clark Howell. My gosh, that guy was insane. Got held up at a border post for 3 weeks trying to get into Ethiopia.
@@cecileroy557 Point is, the entire profession has become DEI-ied and feminized. The fun is gone. The adventure is gone. Very very very very sad.
Fossil hunters 😬? And archaeologists and paleoanths. still exist. I'm a tech. OSHA and the like also exist now. We still work overtime lol. Idk why that would be impressive.
The work is perfectly doable while avoiding wild animals and having a lunch break and carrying adequate water. Not doing all that sounds cute until someone dies. A woman died on her first day of work last year or the year before from heat illness. Not so endearing. Is avoiding workplace death "feminine" to you? We still do plenty of difficult hiking on dangerous terrain where there are wild animals (in north america where i work it is bears, mountain lions, snakes, and alligators) if that's your jam.
The one site I worked on that would meet your fossily interests was located smack in downtown Miami, though. I could go get a fancy latte on lunch and come right back to all the bones and artifacts just on the other side of a construction barrier. Reality never meets what you've built something up to be in your imagination.
I attended ASU and worked on a project for the AZMNH which involved moving artifacts from old digs (which Johanson may well have been involved in as they spanned the time period that he started there- idrk) from museum storage to an outside facility. Everything was labeled and organized by units or coordinates as it would be today. Really, the only things that were different from how they would be done now is that we label in sharpie on plastic bag instead of pencil on paper bag and use a GPS rather than a paper map. We still do ground survey, which is how she was found. It's been methodical for quite a while.
@@yippehanako Oh, I know they exist. They're just personality-less. There's no brashness, bold, in your face, confidence. No more great stories. It's all so bland. The one single person who was old school - Lee Berger, got destroyed for it by his colleagues.
Want to study any form of Human ancestor in real time? Just go to Florida.
Missing 90% of the skeleton.. "look we came from monkeys"
Ah! You did _NOT_ watch the video, I see. And don't be silly; we did NOT descend from monkeys.
They found 40% of Lucy's skeleton and since then, the skeletons of *300 MORE* individuals of the same species. You might find a textbook on evolution to be a great help to your development
@@MossyMozart Ahhhh, you didn't read my comment, it was only one sentence too, be ashamed.
Evolution happened. Cry about it
Evolution happened. Cry
We still have people in New Zealand who are ancestors of this … common links.
Are ALL people in New Zealand racist ? Or just those of British/Dutch descende ?
We did not come from monkeys 🤣🤣🤣🤣🤣🤣🤣. Please, theory is NOT fact.
A fact is any singular datum supported by rigorously and reproducible evidence. It is not "what I really really want to be true." A model is a structure that supports and works with all given data. Evolution is a proven model that is supported by all established facts.
Pleased learn the difference between monkeys and apes.
There is no evidence that we derived from apes. It's speculation. This Lucy story is the biggest lie that scientists force on people even though they have no proof that we evolved from any other species. And if this theory is true, it means some day we will evolve into something else !!!!
Evolution is scientific fact cry about it
I didn't came from a money I come from a rib!
Bbq? If you're A mister then you can't come from a rib. by the way, I'm glad you didn't come from money!
This Lucy business and monkey business is very interesting.
You cannot hundred percent prove it, and you cannot disapprove it.
Therefore, this, my intelligent dream, I make the decision if I develop from a monkey war from what.
@hbendzulla8213 - Evolution has been proven many, many times over. It is the foundation of the study of all of biology. There are BILLIONS of pieces of data and physical evidence that underscore it. It can even be seen to happen right now in front of our eyes. The London Underground mosquitos are an excellent example.
Data is collected/produced by technicians. Interpretation is by a scientist. The present practice of individuals always wearing both hats may not be the best.
Humans were created.
By evolution.
Evolution is scientific fact. Cope
By their mothers and fathers.
Except lucy is fake and never exist and the original bones was actually a oig or something related to a pig
I think this is extreme disrespect! That’s all I will say
to your imagery friend? 😂😂😂
I think the video is _very_ respectful to our possible grandmother, Lucy.
Is this Lucy the Hoax, the one with made up parts along with legitimate parts?
I'm fascinated. How do the bones just appear on the surface? You'd think they'd be buried under years of soils. Genuinely curious
erosion.
if they did not find the fossil it would erode away eventually
One mythology of churchism in competition with another mythology of same churchism...😂😅😂
