Newly discovered Homo sapiens fossils in Jebel Irhoud, Morocco, push back the origins of our species by 100,000 years. The fossils show that by about 300,000 years ago, important changes in our biology and behavior had taken place across most of Africa. In this lecture, Leakey Foundation grantee Shara Bailey discusses her comprehensive study of the Hebel Irhoud cranial and dental remains. She also shares how these fossils are reshaping our understanding of how we evolved.
“Rewriting Modern Human Origins” was presented at the Houston Museum of Natural Science on 11/8/2017 as part of The Leakey Foundation’s Speaker Series program in partnership with the Houston Museum of Natural Science.

Wolves are more similar than modern day dogs from a human point of veiw...All are canines...so it is possible that there wasn't as much variation...and there wouldn't have been so many humans then and they would all be living in the same environment so no need for change...There is also the fact that what we as humans see as major differences in the 'look' of another human is not the same how other species see us and vice versa...

All of this wonderful evidence, painstakingly collected over 60 years by paleontologists like professor Leaky and his colleagues, dovetails with the more modern DNA evidence, and really is sketching out an accurate map of human origins, and our travels on the earth, over millions of years. Very interesting!

My main takeaway from this: Beautiful flat faces doesn't necessarily mean big smart brain. Its kinda mindboggling that we had so many different humanoid species at some point. In my mind this means that we had a common ancestor, split up for a pretty long time to evolve quite differently and then merged again. And what treasures lie below the sahara still and around the then biggest freshwater lake of the world.

I'm very glad to see deeper dates for these Sapiens. It adds a good deal of plausible geology for new analysis around the world. Boehme and David Begun's work also suggests some of what you say here, and I am greatly relieved to see new models replacing exhausted certainties. And I'm also very grateful for the concise technical comparisons of Neanderthal with Sapien dentition. In Bay of Fundy Pre-Hoxnian glacial, and later Dryas deposits, and on the surfaces opened by heavy coastal erosion, I have been seeing very old hominoid heads (often with teeth) in limestone and silicated matrices that are certainly much older than any description of NA humans in the literature. Skulls (and artefacts) are very numerous and various but I won't tax you with my theories about them. The standard maps of Middle Pleistocene Atlantic Canadian glacial conditions are clearly incorrect about the extent of early inhabited coastal land however. Faunal models are also incorrect on the score of the presence of great apes as well. Sapiens and or Neanderthals here carved their petrified heads. Perhaps teeth will settle the matter. This talk was really super. Cheers and all the best. Daniel.

I've almost always believed this time line for ancient humans. However, it does beg a question: What the heck were these humans doing for 300,000 years?

I do believe that several ancient cultures existed, but were destroyed by some horrific natural disasters, which left virtually no traces of them.

[@mnomadvfx]

It depends what you mean by culture. Even the Neanderthals had culture as we now know. What you mean is urban civilisation. This is very rare prior to crop farming, simply because hunter gathering alone cannot support a population of any significant size - you need farming or trade wtih farmers. Livestock farming makes a big difference too, so domestication of wild species of cows, pigs, sheep etc were necessary. All of that took time to develop to a point that it could sustain an urban population leading to the likes of Sumeria and others building the first cities.

As an Australian I'm very interested in any information about Australian Aboriginal peoples origins and what evidence / timeframe there is about this dispersal event / events from Africa to this continent & over what period. I'm no scientist and an absolute novice in this field, but to my eye Aboriginal faces are absolutely fascinating and are vastly different / seem far more ancient than African. Could this be because of their isolation on this continent? That once here there was very little 'mixing' with other modern humans and so they might have stayed truer to the original migration wave 'type'? So, as I understand it, we now know that Aboriginal Australians have been here for at least 70,000 years - which is a phenomenal continuous time line - both genetically & culturally. They are a living modern human & cultural treasure & should be valued as such. You kind of skipped over the Australian history - is that because there isn't much research going on / funded over here compared to the African focus? Or is it merely because it's outside the focus of this presentation? Or both?

I will question her claim that the Sahara region was not desert as recent as a few hundred thousand years ago. Studies on climate change in the region over millions of years, Saharan dust in areas like the Canary Islands & Spain, as well as the movement of tectonic plates and the loss of the vast majority of the Tethys sea show the desert's origins go back at least several million years.

[@darrinwebber4077]

[@larryparis925]

If we could only see where her remote is pointing to when she explains tooth morphology and the PC analysis... that would greatly assist in understanding. Other than that - wow! - this is highly informative. One of my critiques is to get rid of the "garden of eden" trope (26:48) - it's highly ethnocentric, unnecessary, irrelevant, and there were no talking snakes - it provides no empirical worthiness. The graphic at 29:02 is great, as is the explanation and map of general ecological conditions in Africa around 300,000 years ago at 29:14 , and the absence of geographical barriers to human speciation, which, in other words, allows for genetic exchange among various human populations throughout Africa. There is an interesting part at 31:43 , in which Prof. Bailey describes the presence of modern behavior outside of Africa - but which is only partial ("inklings"), "but not the entire package". That, to me, is signicant - over 90,000 ya, "inklings of modern behavior vs the entire package." As she states toward the end, the evolution of fully modern H. sapiens is not an East African process, or a Southern African process, but a pan-African process. Many thanks to Prof. Shara Bailey and the Leakey Foundation for sharing.

[@mnomadvfx]

Yes it stands to reason that evolution can occur faster if several individuals/groups carry different beneficial mutations and eventually meet up, interbreed and their offspring benefit from these multiple sources likely affected differently by the process of natural selection depending on the specifics of the environment the mutations appeared in and the selection pressure caused by those specific factors. I think it would do much better for people to commonly think of evolution in the same way as cross pollinating plants than the way it is often presented as a more linear process - sort of like an evolution web rather than an evolution chain.

All humans interbreed. We are all the same species. So there is no basis for differentiating people on the basis of superficial characteristics like skin or eye colour or curliness of hair.

[@phillyphilly2095]

The basic concept is ‘population.’ Scientists are concerned with the frequency of a gene within a population or the frequency of a phenotypic trait within a population. For example, the percentage of a population that can digest milk into adulthood because of a gene that produces lactase into adulthood. But usually different genes can be and are inherited separately from one another and thus their frequency in a population can fluctuate differently from one another. The same goes for the phenotypic traits caused by genes. Thus the frequency of one gene/trait usually has nothing to do with the frequency of another gene/trait. The ability to digest milk, for instance, has nothing to do with skin color, blood type, ear lobe shape, etc. A ‘race’ is simply a folk category based on an arbitrarily selected set of traits which are (falsely) assumed to go together. Like skin color and eye color. In actuality there is no necessary bond between the traits. Until recently, Europeans had dark skin but blue eyes. The concept of ‘race’ adds nothing to the scientific explanation of gene/trait frequencies in different populations.

Those new fossils had the tidy gene. Everything looks better organised now. Ha! Flatter faces means smaller teeth? Smaller teeth means less chewing? Less chewing means more meat? More meat means smaller stomachs? Smaller stomachs mean faster runners? Compound change should speed up evolution? How would you choose between a Denisovan skeleton or Naledi DNA?

Recent research puts focus on a number of new information, not mentioned in this presentation. Mutation resulting in speech development 80,000+, Toba eruption 74,000 bp(resulting in mass extinction), ice age drying up of the Red Sea once 125,000 bp and again around 60,000 bp, led to migration out of Africa and along Arabian peninsula to Baluchistan to Gujrat sheds new light to a mass extinction and regeneration of population in India, from where there seems to have been a migration of people 45,000 bp, shedding light on migration into China (and into Americas) and south east Asia, with the Important Gauda culture of Bengal. These are perspectives that should be included in any new exposer. Migrations from India to the west explains for example the Indo-European languages (the only rational explanation to date), implying lack of a bigger picture.

[@ryanfitzalan8634]

I think a lot about how the eb and flow of Humid forests and how they grow and contract with climate changes, I don't often hear much about the effects of genetic clines and the powerful macro effects of dominating genetic drift events driven by majority populations within a region. the example i think of is forest dwelling population compared to savannah bush populations; there would be a genetic cline with some populations physically adapting to thick jungle forests while others wander the savannah. During a humid event, arid places decrease and savannahs and forests increase and populations would balloon and large genetic clines would diversify to differing habitats. Than a follow up arid period would aridify huge swaths of territory, pushing forests to contract towards their central humid refuges, while savannahs would do well briefly until aridity dominates to the point of contracting even the savannah bushlands. the question of which populations along the diverse genetic cline, come to dominate the genepool in these contracting events is a very significant one. perhaps at some stages the bush people and their features dominate the tide of genetic drift, while at another point forest populations actually outnumber significantly influence the tide of genetic drift. For certain, it appears that at some point, the populations with technological innovation would create new tidal influences beyond environment, on the drifting genepool.

So the child jaw wasn’t dated directly, as you first said. The dating was also based on a presumption about what layer it belonged to! This kind of sketchy thinking and use of labels is what creates all the noise in science. If for example nobody had sought and found basis for a more precise dating, the first sloppy error would gradually have taken on the weight of fact, even though it started out as an estimate.

[@jamesesselman283]

Really good point....I will add that once an initial error is made the media will cement it into place especially if there are political gains to be had from it. The truth would actually come out over time with further research but oftentimes the media has already decided what the truth is. Michael Mann's hockey stick is one example...It's pretty much been shown to be bunk but you can't criticize it or you'll get called a "denier".

@@Hallands......Hi Hallands.. I have much respect for you and anybody else who wants to get at the real truth. Sometimes the first theory to explain something is right and sometimes it's wrong.

One other thing...your comment was second from the top and after I commented your initial comment got moved way down. Do you think KZbin had something to do with that? Illustrates my point.

[@Hallands.]

​@@jamesesselman283 I think the MSM are highly toxic and by now outright dangerous in America. China and Russia never had a free press and were always totalitarian. But our press and media moved gradually from slanted coverage in the late 80s on to heavy, unapologetic, even aggressive propaganda and deliberate lies, and are by now completely useless, even should they decide to tell the truth, because you’d have to check all the facts anyway. I stopped listening in 2004. Big Tech is almost as destructive with their reckless censorship and so are most politicians who can’t seem to make their minds up whether censorship is most convenient for themselves or a deadly blight clouding the hope and spirit necessary for life. The main problem is that the prime movers rely solely on technology and money for progress. They plum forgot all the living beings, without whom all is for naught, and are well in their way to recreate totalitarianism, suppression and enslavement in a new, horrible form And money is killing education and health-care by cutting corners for profit and forgetting real care. Instead of care we have »supranational institutions« gradually taking lawmaking out of the hands of our elected representatives - oh, and who control these monsters? The biggest foundations, of course, which strangely has begun to function as tax-havens as well! And guess how that came about… The truth cannot be owned. It can’t even be proven, because by the time all the facts are in, it has already changed. This is why we must be truthful and say we "hope, think, believe and assume« unless a high degree of well tested certainty has emerged. But most have lost the ability to distinguish between habits and knowledge in all fields of science. True science must never be swayed by profits. All true science-progress must by now rely on open collaboration. The subjects have become too large to handle otherwise. But the CEOs and the politicians tend to rely on AI to fix that and gradually supplant human research. They’re in for a ghastly setback if they do take that step, but three trying impatiently, investing ginormous amounts of money into developing AI and »quantum computing«.

Nice presentation. Takes her more narrow field of dental morphology and applies it to the wider context of modern human evolution.. I must admit, I couldn't discern some of the variation she describes, but to an expert, it sounds like they are obvious. Well done.

[@UStoRussiawithLove]

My thought is, wouldn’t the teeth be different based on the types of foods eaten? For example, the ridges described, couldn’t they either be or not be worn down? How does that prove anything?

[@christopherneufelt8971]

Neanderthal teeth are NOT all the same! If you want to find "Neanderthal" teeth in modern humans, talk to some dentists in Saudi Arabia! The Taurodont molars found in Neanderthals will also often be found in the children of Bantu & Melanesians crosses. If you get the right mix of modern human genes you will get "Neanderthal" teeth. And it was primarily the teeth that Germans declared to be so different that they must be a separate species.
