The narrator and guest work well together. He asks intelligent, pertinent questions and lets the articulate expert answer without interruption. Rare and most appreciated.
34:46 Great Image. I met the Turkana Boy when I was in Naiobi 20 years ago. Well, I stood in front of him. Fasinating! I also met the man who found him, he was then appointed a curator at the Naiobi Natural History Museum. The lady Director of the Museum was walking past, saw my interest and asked me if I would like to meet the Turkana Boy's discoverer, which I really did want to! Such a beautiful and humble man. I think the beautiful Turkanya Boy died of blood poisoning from some tooth abscesses, fell/laid down into Lake Turkanya and was covered by silt until this time. What a marvellous trip to Kenya I had!
Wonderful chat, appreciated her knowledge and passion, and she kind of looks like Drew Barrymore. Thanks to you both for an educational and enjoyable video.
This is a wonderful, informative Q&A. Extremely well done, and Mark is the paragon of an interviewer - totally prepared. I especially appreciated the discussion of potential climatic selection, the frontal bone, and facial structure beginning at 17:13 . The discussion of variation of Homo morphology across regions, and across time, is explicitly pointed out. Also, note the carefulness of how Prof. Baab presents the information, particularly in how it can be interpreted in more than one way. I suspect she is an excellent instructor. Many thanks for this. Wow! - Larry, San Diego.
You two did an amazing job parsing out a fuzzy, complicated subject! I could listen to Dr Baab speak all day! Found you on Instagram, thought I’d check out your TH-cam channel, definitely subscribing. Cheers!
Oh I needed this …..) Been bingeing everything on human anthropology for 2 years and really needed this incredibly detailed summary on erectus to help put the pieces together 🤙🏼 thank you..
Yes, it's not easy to find someone who will give this amount of scientific information for almost 45 minutes without making listeners tired or uninterested
Thank you so much; about fifteen years ago, I read a fascinating, peer-reviewed article regarding the ginger gene in Homo Neanderthal and Homo Sapiens and their implications. I’d been interested in paleo anthropology but that absolutely hooked me and I’ve been in love with it ever since. Australopithecines and H Floresiensis have my very gooey bits❤️. I just discovered your channel, so you’ll probably see me in the comments section frequently.
Didn’t they expand by following the Mediterranean coasts, exploiting shoreline seafood resources? Or was that early sapiens, I can’t remember. It’s so nice to hear from not only a true expert scientist, but one who is such an effective teacher. She doesn’t bury us in scientific lingo, but nor does she dumb down. She reminds me of the great advice I got as a young scientist, to write and speak for the intelligent, but uniformed, listener or reader. Later in my career, when I was doing lot of editing, I rejected a some reports and papers because they were unintelligible to an itelligent person who just wasn’t learned in that specialty, even other scientists from the same board field. Most scientists, I think, underestimate the comprehension and intelligence of non-scientists. Or, others try to impress by using highly specific, technical language. Every science communication, spoken or written, should be this sparse, elegant and clear!
Actually none of the species did, even Homo Sapiens. They all tended to go east at first, so much that our species "discovered" Australia 10,000 years before they entered Europe. Towards the rising Sun for some reason, it seems. Also they were not so much bound by the seashore, but by fresh drinkable water. Even the Dmanisi remains talked about in this video were in the neighbourhood of a river, not the Black Sea.
I really appreciated getting the latest info on things like "perhaps Turkana Boy was somewhat incorrectly reassembled; and that the ribs and pelvis might have wider, more primitive relationships than originally thought." And that a recently discovered pelvis of the same species shows this wider, more flared setting of the pelvis. So cutting edge and cool. Thank you so much for your in-depth interviews.
It’s amazing how much variance occurs just within one species. Contemporary humans are statistically taller than our relatives just 100 years ago. Now apply that over hundreds of thousands and millions of years.
We are so fortunate to have scholars such as this lady sharing their knowledge on the internet. The high level of self-awareness that we humans possess including that of the inevitability of our death, both builds us up and drags us down - is a blessing and a curse. There is some evidence that Neanderthals too prepared ritual burial plots for their deceased. RIP to all - Rest in Peace/Pieces?
The sea level was much much lower because of the huge ice caps, so rather than an archipelago Indonesia would be a land mass connected directly to Asia. This made it much easier to reach distant areas, but also means large parts of their habitat is now submerged. It was very interesting to hear about the taxonomy debate. It is odd that almost two million years of human development is classified as one species, while modern hss, neanderthals, denisovans and florensis are counted as 4 just in the last half million. Probably denisovans and neanderthals should be called sub species, but when we ourselves are involved emotions arise.
Time alone doesn't define speciation. Species are human categories to begin with as in reality genotypic and phenotypic differences are on a gradient and not on either side of a tidy line of demarcation. Chris Stringer's work on archaic introgression really illuminates the subject.
The implied differences that occured within the Homo erectus spicies itself ie the Asien group vs the African group would explain why Erectus perished and died out. The African group evolved into anatomically modern man around 300 ky. Perhaps earlier during the Ice Age in Eurasia, Homo Erectus outside of Africa underwent significant changes to evolve into Heidelbergensis, Neanderthals and Denisovan. The dead end of Erectus then died out for lack of food.
In the documentary Planet Of The Apemen: Battle For Earth, there was a scene where they talked about the Asian Erectus being unable to throw a spear because its shoulders were not like ours.
Very interesting presentation! "Pithecanthropus" means "Apeman", not "apelike". The same composite word (pithecus = ape + anthropus = man) is still in use in Greek, with exactly the same meaning. Thanks for sharing!
Thank you for clarifying. I love that about using greek and Latin for our science. I hate how we name illnesses and discoveries after people. I mean .. it's nice and all to honor the person but a disease like "Lou Gehrig's disease" tells us absolutely nothing unless you know who Lou was and what happened to him.
Scientists have identified a stretch of our DNA that appears to be from an archaic ancestor. That stretch could indeed be from Homo erectus but it could also be introgression from another ancestral species.
“The frontal bone could reflect an adaptation to climate?” How? How is the size and shape of one’s brow reflective of climate? How does a thicker frontal bone help or harm one’s reaction to the weather? How? Tell me, I want to know!
The size of people varies with their living conditions ... especially their diet. So the findings may not been typical for the generation or place. In Europe, after the last wars, this has become clear to this day. Variations of Homo Erectus can appear within a short time if dietary factors change. In addition, migratory movements can lead to erroneous assumptions about membership. Finds scattered around the world and differing in time for many thousands of years ... rather testify to further (not yet found) distribution and repeated settlement of particularly suitable locations. The long history of Ohalo ii up to the present day (13k years) already testifies to considerable advance development (hierarchy, structural engineering, logistics) through the spread of settlements of similar character ... But that is only a short wink regarding the time of existence of homo erectus. The social and thus genetic connections only become clearer with greater statistical significance over more finds.
The heavy brow ridge on all these early hominids was great for storing a pencil ✏️ horizontally when climbing a ladder 🪜 Kind of like when carpenters today use the back of their ear 👂 to hold that pencil while they work on a ladder.
If Homo erectors is estimated to have been in Java for maybe 100,000 years then it’s not hard to imagine that the aboriginal Australians may well be the descendants of homo rectus also, and that Australia is perhaps likely to have been inhabited much much longer than 65,000 years.
One of the major outliers of the H. erectus line seems to be the population in Georgia with more primitive characteristics. That suggests to me that they may have undergone the earliest migration of the species out of east Africa and then became isolated from the rest of the H. erectus line, eventually dying out. If so, then there must have been several migratory episodes out of Africa to the east - and at least one back to east Africa to account for the more advanced form of the species found there. Apparently H. erectus may also have had immigration issues that we face!!! Lol!!!
Second time I have watched it. I would love to know a bit about the skulls on the cabinet in the background. Why those two? Left Skull Homo Sapien? Right side Erectus? (the viewers left and right not hers).
As a biologist I find it interesting that the Sanskrit Vedas say humanity is 2.4Million years old, which would make homo erectus human. Something else I find odd is that it's claimed that two gorillas chromosomes fused in humans or human ancestor when it makes a lot more sense physically speaking for a chromosome to split. That means multiple people had to have that same genetic mutation with a fusion of chromosomes at least one of each sex in order for them to produce children that also had it.
Could the browbone adapt to a more prominent shape to shade the eyes better in a sunnier climate? Or to protect the eyes from cold and snow? This last one is prompted by knowing a few otherwise high-latitude trait (tall, long head and body, very light blue-eyed blondes), Europeans with extremely prominent browbones for modern humans. Or could this just be from a higher percentage of Neanderthal genes? I know all Eurasians have some, mostly western Eurasians.
There was a major ice age right after a warning period just like now but 120k yrs ago... It takes a while to come out of a major ice age and the first evidence of villages is 84 plus thousand years ago... Which would have been about the time we were finally coming out of the Ice Age. Homo erectus barely made it to the end of the Ice Age. Genetic data is skewed at about 100k yrs back because of all the genetic bottlenecks we've had but mainly the Ice Age every 100-120k yrs.
It’s fascinating that it appears our ancestors gradually developed the human form long before they ever developed the human brain. Fortunately, our ancestors became more attractive before they became, “self aware!”
Perhaps Homo erectus had not developed the 'science' of lighting fires to cook their meat. Raw meat is very tough and so strong jaw muscles would be required - hence the muscle anchorage ridges at the back of their heads. When Hominins had developed the technique of lighting fires, their skulls would become more gracile - or child-like - as in H. heidelbergensis. The uplifting of the forehead into a vertical position could have also been part of this neotenic development.
hey y’all, i’m really interested in biological anthropology and paleoanthropology does anyone have any university recommendations where i could pursue that?
Noone talks about the toba eruption, i think thats the cause for the homo sapien bottleneck that happened at the time and the reason homosapiens were able to travel the world as i believe it greatly decreased the population of of archaic humans allowing our ancestor to move into thier land with more safety and allowing them to keep there genenome mostly homosapien as there were less archaic humans (to breed with) in the area after the eruption.
Very illuminating. Quite a great interview, with someone that clearly loves her work! Thanks for this video - the best I can do in return is a like and this comment for the Almighty Algorithm.
40:10 since it is harder to live at higher latitudes, requires more knowledge and technology, more brains to succeed, then could that drive evolution by selecting for the 'smarter' in early Eurasian homo populations?
I count that the foot fits perfectly between inner elbow and wrist to determan most an anatomicly modern human. Do u know a sciantific basis for this theory?
37:34-37:50 ... and then the homo erectus form returned to the hills of the (*) a couple hundred years ago. * fill in your favorite Ozarks, Appalachians, ...
Gibbons and Orangutans are bipedal. Humans are also excellent tree climbers. These things used to separate us from the other apes, but we know THAT is not the major difference. The difference is that mankind is the one that strays from ways of his ancestors.
Native Americans tribes differ greatly in body size. So do African people's. I'm with the lumpers. Less species and more just variations in the same species. Not every new skull found is a new species.
Many desert dwelling species have evolved biological mechanisms to carry water reserves with them. Think of a camel. Other species have evolved a remarkable ability to remember locations where water can be found. This is probably the answer to the question of why do elephant never forget. But as far as I know humans are the only species that has learned how to carry water with them using a container, be it naturally occurring such as sea shell or egg shell, or something that requires some degree of modification like a hollowed out gourd. Under the theory that persistence hunting was earliest method used by humans to run down game and finally kill them when the ultimately overheat and collapse from exhaustion, the capability to carry water would have been an absolutely necessary prerequisite. As the first human species to migrate out of Africa and colonize vast distances into Europe and Asia, Homo Erectus must have been developed a method of carrying water with them over long distances. I'd go so far as to wager it was probably this persistence hunting technique that led to Homo Erectus migration. With so much emphasis placed on the mastery of fire and the hand ax as the earliest steps to humanization, it was probably the use of privative water containers that paved the way for our evolution.

Under the theory that persistence hunting was earliest method used by humans to run down game and finally kill them when the ultimately overheat and collapse from exhaustion, the capability to carry water would have been an absolutely necessary prerequisite. As the first human species to migrate out of Africa and colonize vast distances into Europe and Asia, Homo Erectus must have been developed a method of carrying water with them over long distances. I'd go so far as to wager it was probably this persistence hunting technique that led to Homo Erectus migration. With so much emphasis placed on the mastery of fire and the hand ax as the earliest steps to humanization, it was probably the use of privative water containers that paved the way for our evolution.
Came to giggle at "homo erectus"
Stayed for the film
Is it possible that homo erectus saw Uranus?
Arizona is in the Southwest US, not the Midwest
