David Reich - How One Small Tribe Conquered the World 70,000 Years Ago

[@chetisanhart3457]

When a brilliant person says "I don't know" so many times, it gives me hope for humankind. ...and that he is a fellow N.American...wow. I didn't think we did that anymore. Thank you both for this interview.

[@MrDubyadee1]

True. Its one way to tell the difference between a brilliant or very smart person and a pretender.

[@harrietharlow9929]

I'm glad he admits this because we really don't know a lot about our past. We're learning. but we're not there yet (and I doubt we ever will get there since so much has been lost).

[@718EngrCo]

I have found that “I don’t know” is very difficult to say, but it is very important. It informs others, but more importantly reminds yourself that you have limitations. Of course everyone else already knows you have limitations but you sometimes delude yourself.

[@ashleigh3021]

“Fellow N. American” what does this mean?

[@tobystewart4403]

The way David Reich speaks, his manner of phrasing possibilities rather than certainties, is a great credit to his intellectual standing. He does not think in terms of simple certainties, leaping from broad postulations of fact to far reaching conclusions. Rather, he is more interested in comparing possible alternatives, and questions popular models by always examining them against different models. One would be extremely fortunate to work with him, or be a student learning from him.

[@ynwicks7142]

Now this is a real scientist. He is precise and is able to confidently say "I don't know". Unlike many egotists in science nowadays making ridiculous claims.

[@lewissmith350]

[@jeremymullens7167]

He’s suggesting a truth when the established model is resistant to that.(Nazi ideology kinda hampered a lot of science and social science models because no one wants to be associated with it) He knows what likely happened because we have examples for the historic record and human behavior all across the world. Men from a culture killed the men from another culture and took their women. That’s how you get a dramatic demographic shift. Disease can contribute but stuff like that happens a lot. The Men winning wars lend their DNA to future generations. This even happened in the modern era to an extent. Some of it could be female mate selection where they leave their family. The human profile tends towards male expansion but females have an adventurous risk accepting type at a lower frequency. If you think of the male/female behavior, it kinda paints a picture. Men are more accepting of risk with some proportion being more risk adverse. Some portion stay behind, and some portion goes out. You need both. We also have a set up where younger men take more risk and older men less risk. All these things are biological. If you want a wife, you have to go win one from an enemy.

[@rionorman6775]

​@@jeremymullens7167well shit

[@numshy101]

@@jeremymullens7167From my understanding, evidence show that the spread of Y dna of a group over another cannot all the time be attributed to the males of the first killing off all the males of the other and procreating with all the females. He suggests that interactions of humans with Neanderthal is not that. It seems over a long period, some human males will procreate within a group of neanderthals. This happened all over. Until such tine many of the Neanderthal groups have a significant human DNA. It might be the Neanderthals realized they needed more genetic diversity and since maybe because of their lesser developed vocal tracts they were less able to merge with other groups. So they might have captured human males who wandered into their territory. The group of farmers in Britain is also probably a different scenario. It would be unlikely that the invading Y dna group killed off the males and continued the farming culture of the invaded group. Same with the Austronesians. It would be unlikely for a sea nomadic group to simply wipe out the males of the population of every group they encounter. The case for this scenario might apply to the Beaker people discussed and the prior culture. The culture was wiped out as well as the Dna. So this might be that all the males were killed by the invading group. But again it seems the models and evidence show that that is not the only way Y dna spreads and dominates a population.

[@marjus89]

Incredible talk! Brilliant contribution from Dr. David Reich, simply riveting and mind-blowing to realize as an adult that the out of Africa only genesis for 'modern humans' is not totally correct. To think that Eurasians for example are possibly more admixture of Neanderthals and Denisovans than strictly modern humans out of Africa with a touch of those other sub groups is wild. This honestly makes much more sense when you think about all the other patterns of evidence and diversity that we see today.

[@penelopehunt2371]

Totally agree. The Out of Africa thing never ever made sense . Not ever

[@Casualphilosopher-db9gy]

I come from Eurasia region and I remember we studied about these Kurgans and early people in history lessons in schools. There are plenty of them in my country. Thankfully now DNA testing makes it easier. Anyways, I never heard my history teachers mention that we all come from Africa. We have people in this region since Stone Age. There are very early burials and sights. I only started hearing we all come from Africa past 2015 in US media and I always wondered why I never heard it before. We did study all existing early human remains found on Earth, not just our region, bc our course in the world history was extensive to say the least (when it comes to the earliest humans, there aren’t too many of those found). So different people and caves found in different parts of the world, and approximate dates. Ofc after so many years I no longer remember the details of what I studied in the secondary school. But never even once I heard that we all come from Africa. I did recently hear US historians say those Early Eurasians who lived in Central Asia and Southern Siberia had dark skin bc light skin wasn’t developed yet. I don’t know if it’s a theory or they found something in their DNA to suggest that, cause at this point all we see from them is very old bones and some remains of their objects.

[@RamZar50]

David Reich is brilliant on Ancient DNA as much as Svante Pääbo who won the Nobel Prize in 2022. Reich’s 2019 book “Who We Are and How We Got Here: Ancient DNA and the New Science of the Human Past” lays a lucid foundation. I remember thinking years ago about how civilization expanded and Ancient DNA along with archaeology give lots of clues. Another was the book by David Anthony: “The Horse, the Wheel, and Language: How Bronze-Age Riders from the Eurasian Steppes Shaped the Modern World”. That’s when we find out about the Yamnaya culture in the Pontic-Caspian Eurasian Steppe (West) region and then the Sintashta. Horse domestication for riding occurred in the same region.

About Yamnaya, its interesting that the old norse mythology written down by Snorre Sturlason at ca 1200 AD, "Ynglingesagen", describes the main God/chief, "Odin", comming from an area east of the river Don by the Black Sea: "The country east of Tanakvisl (Don) in Asia was called Åsaland or Åsaheim, and the main castle in the country they called Åsgård. One named Odin was chief of the castle".

[@rossstewart9475]

I'm feeling particularly slow today, so just to be clear I'm understanding: If the story holds water, the fundamental implication here is that the gods of Norse mythology were, in fact, simply proto-Kazakhs who rode in one day and did/said something cool? Neat!

[@dragongirlguitar]

@@rossstewart9475there are stories in the sagas of something like this. As in Odin being a real human ancestor.

​@@zillakamikaze5551that's because it's ancestor worship. But they are far from the only ones who are guilty of this. Caananites Babylonians, Egyptians, and all the little tribes absorbed by the hindi peoples added them to their roster. The Chinese still worship their ancestors, Native Americans retained some version of a supreme ancient diety but they were heavily into ancestor worship. The tragedy of this whole thing is that he needs to check out Neil Jeansons work, in 2022ish published a book called Traced. It's very technical and very dry but he does a good job of walking the readers through various events that have left clear echoes in the genetic record. There's definitely a bottleneck event near the Time of the Yamnaya, but I'm going to let y'all figure it out...

Because it's not evolution in the strict Darwinian sense of it. It's far far a more complicated process than that.

[@zrymill]

Their models are always out of date. The constant updates are handy, but the standard dogma seems to exclude any form of intervention by more advanced species from or located on either this planet or other planets. According to Theosophy (Secret Doctrine by Helena Blavatsky), the spark of mind was implanted in animal man around 21 million years ago. Modern science will catch up eventually, at least they're not pandering to Darwin and the fundamentalist Christians anymore.

[@drewbester]

[@Andy_Babb]

I need like an animated map showing all the known human species’ evolution, migrations, meetings/mating with other human species, where they went once they left, how many migrations happened and just all of it lol it’s so hard to get even a broad picture in my head… granted, I guess that’s also how science feels right now lol but I wish I could just have a better basic understanding of how we got where we are. I try reading but I’m dyslexic, so, challenging at times haha

The new simplified human tree starts with erectus who branches off denisovan a million years ago and then branched off sapiens 250,000 years ago. These are the only three species of homo. All other variants of homo were offshoots of erectus that died off before they created successor lineages,.. or they bred back into the direct lineal descent of erectus. Neanderthal is of direct lineal descent from erectus and not a branch. He is a regional variant of erectus just like all the heidleberginsis, habilis, tang, Damasili, dragon skull, rodiesan, flores, naledi skulls etc... all of them are variants of erectus, denisovan or sapiens. This is not the dyslexic version, it's the results of research into the African ghost population in Nigeria where there exists people with a 19% autosomal genetic match to erectus. Within this 19% archaic dna is super-archaic dna going back to australopichicene and dna we share with the bonobo. However, the results are so extreme that it will take a couple generations to integrate it into society.

Rather than slap gap filler terms like dark matter to make the numbers fit our theories, we should acknowledge the shortcomings of current understanding. Too many people believe theories of current models are settled science (even scientists) and this impedes forward progress when large amounts of energy are wasted arguing with people about the things they think they know.

The most striking thing I've learned from researching family history is that small numbers of immigrants swamped indigenous populations very quickly. And those small numbers ballooned over the last 100 years or so. The population in my home town grew from about 762,000 to 2.5 million during my life time. For my mother it was less than 500,000 to 2.5 million. Most people alive today are indeed cousins.

Population grows through birth has clear upper limits, impossible to get from less than 300.000 to over a million in your life time.

Excellent guest and discussion. Thank you!

[@jimgraham6722]

Great discussion. As we learn more, the history of human origins is a truly amazing story. 33:07 There is no evidence Tasmanian aboriginal people lost fire. From an official history of Aboriginal Tasmanians "Tasmanian Aboriginal people made fire using flints and fire drills. The flint created sparks when it was struck against another stone. Fire drills were pieces of hardwood that were rubbed or spun on a piece of softwood. The rapid rubbing or turning heated the softwood until it was hot enough to light some grass laid on the wood. For convenience Aboriginal people carried fire sticks especially when hunting - so they did not need to create fire everyday. The dry grasslands provided excellent fuel for fire, creating flames and smoke that flushed wallaby, wombat, bandicoot, bettongs, potoroos, possums, echidna, blue tongue lizards, and emu out of cover where they could be easily speared or clubbed." As an aside before European contact the Aboriginal people of Tasmania numbered in the tens of thousands. The story goes they knew they had once been part of a larger world but believed that it had been lost in the flood. They consequently thought they were the last surviving people on earth.

In the pre DNA 60s one theory of the origin of human nations traced common linguistic traits.

Indo European with roots in Sanskrit was thought to be the mother of European languages. The picture is now so much more interesting with genetics and anthropological research.

[@spellandshield]

There is no clear evidence that Hungarian and Finnish (which are related, i.e. Finno-Ugric) are related to Turkic or Mongolian languagages; they share certain typological features, being for example agglutinative in terms of morphology but many languages are and there is no clear genetic relationship between these groups.

Its funny that the devil has cloven hooves though- not horses hooves! One driver of people north and west may have been the cool summer seasons and the abundance of grass. The Middle East went through some extreme drought periods. The sheep and goat herding wasnt great for fragile hotter climate soils. Its easy for organic matter to burn out rapidly. Maybe the sheep and goats came with the horsemen. In tbe Danube River valley, trade would have been fairly easy. Maybe we need to trace animal ancestry! Otherwise, you drive your sheep south over fall and winter to reach the markets. When drought hits, food becomes worth a fortune! Some people are tracing precious metal signatures too. You can tell where peoples trade extended to.

The reference to Aboriginal Tasmanians is ahistorical. Like the indigenous groups on the mainland, there is enormous weight of evidence of Tasmanian Aboriginals using fire stick farming. The Bay of Fires was named by English navigator Tobias Furneaux in 1773 when he saw fires burning along the coast, lit by Tasmanian Aboriginal people. There are contemporary reports of use of flints and fire drills.

I like the theory that when the community size reaches a critical mass it sustains cultural knowledge and this gains momentum so that knowledge starts accelerating. Once a community is large enough to specialize workers and gain transformational technologies it becomes dominant over lesser tribes whose development has stagnated. So the key success factor is ability to adhere in a common cultural community identity. The ability to see oneself as a part of a greater whole and commit to the greater community's success rather than personal success. Dominance might not be merely military. Ability to grow and store and distribute food means a population that is more resilient to changing weather, disease, etc. Lessor communities simply can't survive. Greater communities survive and thrive. Its all a fascinating discussion.

I think if you contributed less often, you might feel more freedom to slow down and more fully explain your. thoughts. Because the interview is not about you, I think you feel you have to rush through your thoughts and cut them short. This is totally understandable.

[@JT96708]

I am puzzled by the use of the word ‘species.’ I took a bio course in college in the 80’s where I was taught that if two individuals could breed and create a fertile offspring, they must be from the same species. Given that definition, all of the dna evidence that shows successful between breeding Neanderthals and modern humans indicates that they are the same species. Has the basic definition changed?

[@riottonitedragon8344]

Neanderthals and Denisovans are the same species as modern living humans. Most genealogists classify them as a subspecies of modern humans. But they are more closely related to us then Erectus, or Habilus. To my understanding I think of them as different breeds to the same species. Like a pit bull and a Rottweiler are two breeds that descended from a wolf. If that makes sense.

[@kennybachman35]

That’s the creationist definition of species. Speciation and hybridization are not only possible, but a fundamental part of understanding evolution.

[@kennybachman35]

@@riottonitedragon8344incorrect.

[@violentfox]

A lot has changed since the 80s. Certain inter-species hybrids were able to produce fertile offspring, like Grizzly and polar bears. Still contrast-different ecology and behaviors of both species. On the other hand, Ring species became a thing (google it up). All that rendered the old offspring-based approach outdated.

An important point is because of the nature of DNA survival there may be regions of the world where we never will find archaic human DNA of the residents there, so we may never get a complete and accuracy picture of human. In addition there is a big political movement which extends to academics in the social scientists, almost exclusively in the US, to not allow study of ancient DNA. It is a very powerful movement in the US.

[@Nylon_riot]

I loathe these people. There is no bigger sin than trying to erase or change someone else's history, I don't care how uncomfortable it makes you. The US is a very religious nation that was started by multiple extremist groups of Protestants, that is not stained by an orthodoxy in accordance with the Constitution. Because Jefferson and Madison really had an issue with the Church of England. This makes Americans really prone to radicalization. It is a new Puritanism. That doesn't mean other countries can't take up the mantle.

i think it's weirder that we don't discuss the actual differences in intelligence that we see today. To suggest that there was a wave of intellect, when today i see people with such a wide range of intellectual differences that at some point people are actually too intellectually weak to understand intellect and the idea that there are ranges of it.

[@Squared_Table]

Intellect is the source of “humanness” as we know it. Its presence looms over every corner of our psychology, our actions, our identity. Of course, that means openly admitting to these immutable qualities or attempting to make progress in any sort of meaningful scientific discourse would mean no less than complete existential upheaval and outrage for the vast majority of people. That’s why the higher ups are willing to viciously ostracize scientists and shamelessly lie all in the name of maintaining that facade of inborn equality.

I remember I was working with UCD PHD students and told them about what David was saying. They instantly started to express that it sounded racist and immediately took offense to it. I implored them to listen to him themselves, and surly they would be able to easily understand what he was saying. A week later, I brought him up again, and they immediately said what he was saying made complete sense. Their conclusion was that this information made them fearful, that it would be used and championed by racist. I told them I was fearful that people like them were in academia and were positioned to higher positions in our public health workforce, and that they were more interested in holding up falsehoods, instead of adjusting to facts. Ever since then, I knew academia was probably not what it was all cut out to be.

I am confused with the term ‘sub-saharan Africa’ in a conversation about ancient Africa when the Sahara was often green. Wasn’t it green up to even up 3000 B.C.E? Sub-Sahara seems to be an artificial delineation when it comes how humans have been moving through the continent

[@alisterdirector1475]

Sub-Saharan African is rooted in racism and is a racist control tactic that creates the false narrative theat Black Africans could not move beyond the Sahara. It is literally a term used to control the narrative of dark skinned Africans.

[@gailnorman1133]

It's a geographic term and includes central and southern Africa.

[@alisterdirector1475]

​@@gailnorman1133 if sub-saharan Africa was just a geographical term, we would refer to North Africa as North Saharan Africa or above Saharan Africa, which we do not. Sub-saharan Africa was specifically chosen as a way to control the narrative of Black Africans. White supremacy is extremely intentional with its wording.

[@acaydia2982]

The Sahara wasn’t all green. It was more of a savanna grassland. The desert around Egypt always existed. You can look at the studies. It still would have served as a barrier. It may not have been a 100% barrier, but more of a 95% barrier. Then you have to imagine the tribalism like we see elsewhere.
