    10% of pediatric cancer is linked to a single-gene variation. These variants can be detected in embryos before pregnancy begins. Orchid’s whole genome embryo reports can help mitigate your child’s risk for cancer by screening for 90+ genetic variants linked to pediatric cancer. Discuss embryo screening and IVF with a genetics expert.

    On this episode of Unsupervised Learning Razib talks about the April 2024 preprint The Genetic Origin of the Indo-Europeans. This blockbuster publication introduces nearly 300 new ancient DNA samples, uncovers the origins of the Yamnaya, and delves into how they transformed the genetic and cultural landscape of Eurasia ~5,000 years ago.

    Razib addresses:

    * The now-identified ancestors of the Yamnaya

    * The genetic landscape between the Dnieper, Volga and Caucasus before the Yamnaya and that region’s numerous distinct populations

    * When the Yamnaya came into being as a distinct genetic-cultural cluster (after 4000 BC)

    * The relationship of the Yamnaya to the Anatolian Hittites and the newly refined idea of an Indo-Anatolian (as opposed to Indo-European) language family

    * The region where proto-Indo-Anatolian languages likely flourished, and why they disappeared

    * The population-genetic landscape of clines vs. clusters in human genetic structure over historical time

  • Eric Cline: After 1177 B.C.
    This is a free preview of a paid episode. To hear more, visit www.razibkhan.com

    If you have a sibling with autism, your future child’s risk for an autism diagnosis is increased by 2 - 3.5x. Orchid’s whole genome embryo reports can help mitigate your child’s risk by screening for 200+ genetic variants definitively linked to autism and other neurodevelopmental disorders. Discuss your situation with a genetics expert. 

    On this episode of Unsupervised Learning Razib talks to George Washington University archaeologist Eric Cline. The author of 1177 B.C. - The Year Civilization Collapsed, Cline has a new book out, After 1177 B.C. - The Survival of Civilizations. While 1177 B.C. closed with the end of the first global civilization, that of the Eastern Mediterranean at the end of the Bronze Age, After 1177 B.C. tells the story of those who picked up the pieces. But first Cline and Razib talk about the popular appetite for ancient history, and how 1177 B.C. became a surprise bestseller. Cline’s training is in archaeology and they discuss how new technologies like ancient DNA and isotope analysis are now contributing to transforming our understanding of the past.

    Then they turn to he organization of After 1177 B.C., how Cline decided to build on regional geographically focused histories rather than constructing a tightly integrated single narrative thread. This gets to the reality that the period covered in After 1177 B.C. is one of disintegration and isolation, as the networks binding together ancient Near Eastern kingdoms collapsed, with some states like that of the Hittites disappearing, and others like Egypt re-emerging sharply restructured. 

    Cline and Razib also discuss the lacunae in our understanding of the past, and the possibility that civilization may have gone through more cycles than we yet understand, with perhaps some social and technological complexity in the Pleistocene that we had not previously anticipated. Cline points out that Göbekli Tepe certainly must have had precursors in the Pleistocene, as local people could not have constructed such a site without skill and know-how accumulated over generations.

  • John Massey: Chinese dreams through Western eyes

    For the first time ever, parents going through IVF can use whole genome sequencing to screen their embryos for hundreds of conditions. Harness the power of genetics to keep your family safe, with Orchid. Check them out at orchidhealth.com.

    On this unusual “from the vault” episode of Unsupervised Learning, Razib talks to John Massey, a retired Australian engineer who has been a long-time correspondent. Massey and Razib recorded this podcast in the spring of 2021, at the height of the COVID-19 pandemic. At that time, Australia and China were enacting strict lockdowns to halt the spread of the virus, while the US and Europe were already taking a more relaxed approach. Though the conversation is a bit of a temporal rewind, back to a time when Americans were more worried about infection than inflation, the overarching theme is the role of China in the world and its possible future history.

    Massey, though an Australian, has married into an ethnic Chinese family, and some of his grandchildren live in China. The current great power tension of the 21st century is clearly China vs. the US, and in this battle Massey takes a broadly pro-Chinese stance. This is obviously a minority view for Westerners, but it is not entirely unheard of, with even voices as prominent as Thomas Friedman, columnist at The New York Times, waxing poetic about Chinese technocratic efficiency. Prior to its recent economic doldrums and fertility problems, the narrative of China ascendant was dominant and overpowering, and Massey reflects a faction of the West that still believes that Asian power’s preeminence is inevitable, given the forces of history. For them, the fundamental question is simply how we in the West will adapt to it.

    On this episode of Unsupervised Learning Razib talks to Colin Wright, a returning guest, host of the Reality’s Last Stand Substack and a fellow at the Manhattan Institute. Before digging deep into the biology of sex and the cultural politics of gender ideology, Razib and Wright touch on what’s been happening to Jonathan Pruitt, Wright’s erstwhile advisor. He was accused of academic fraud in 2019, and dozens of papers where Pruitt was the primary contributor of data had to be retracted. Notably, papers where his mentees collected the data did not suffer from the same problems. Evidence quickly mounted that Pruitt’s whole career productivity was built on fraudulent data. As of 2024, Pruitt’s university, McMaster, where he had an endowed chair, found him to be guilty of fraud, while his doctoral dissertation from University of Tennessee was withdrawn. He resigned from his university in 2022, and embarked on a fantasy writing career. Today he is the author of the dark fantasy, The Amber Menhir.

    Then Razib and Wright talk about the current state of gender ideology, and the conflicts around trans rights in the US and abroad. Wright, who is working on a book on sex and gender, believes we may have seen the high tide of gender ideology, with the retreat occuring earlier abroad in places like Britain, where youth medical gender transition has been severely curtailed. He also reviews the major terms and concepts, like the difference between sex and gender, and also what exactly is meant by binary sex and why it is so important in our ability to understand biology generally and patterns in human society specifically. Finally, Razib asks Wright to expound on the different factions in the “gender wars,” from gender critical TERFs to social conservatives and queer theorists.

    On this episode of Unsupervised Learning Razib talks to Kristian Kristiansen, an archaeologist at the University of Gothenburg and affiliate professor at the Lundbech Center for Geogenetics, Copenhagen University. A past guest on this podcast, Kristiansen has recently contributed to an astonishing lineup of landmark papers published in Nature just in the last few months, Population genomics of post-glacial western Eurasia, Elevated genetic risk for multiple sclerosis emerged in steppe pastoralist populations, 100 ancient genomes show repeated population turnovers in Neolithic Denmark and The selection landscape and genetic legacy of ancient Eurasians. They also discuss his chapter in the 2023 book The Indo-European Puzzle Revisited: Integrating Archaeology, Genetics, and Linguistics.

    Razib and Kristiansen discuss the state of the emerging synthesis between archaeology, genetics and historical linguistics. Though himself an archaeologist, Kristiansen admits that in many ways historical linguists were correct, with models of mass migration now overturning those of cultural diffusion. He also gives a high-level summary of soon-to-be-published work on the spread of plague in Europe 5,000 years ago, and its role in the collapse of Neolithic civilization and the rise of steppe Indo-Europeans. Kristiansen gives a summary of recent developments in understanding the archaeology of Bronze Age Northern Europe, and in particular the expansion of the Corded Ware people. Razib and Kristiansen also discuss the role of distinct migration streams of the steppe people and their contribution to various Indo-European populations. Is it time to wonder if the Greeks descended from Corded Ware or Yamnaya?

  • Samo Burja: Palladium Magazine, China, Russia and the future of Eurasia
    This is a free preview of a paid episode. To hear more, visit www.razibkhan.com

    Today on Unsupervised Learning, Razib talks to long-time podcast favorite Samo Burja. Burja is the founder of Bismarck Analysis and Bismarck Brief, a Research Fellow at the Long Now Foundation and The Foresight Institute. He is also now the chair of the editorial board of Palladium Magazine. Already a four-time guest on Unsupervised Learning (he has previously shared his views on China's future, Russia's present and archaeology's past, his role at Bismarck Analysis and geopolitical uncertainty, reflected on his piece in Palladium on Finding "lost civilizations" and covered his ideas on "social technology," China, and the foreign view of America), the Slovenian-born Burja is one of the most original and incisive public intellectuals writing in America today. His 2021 piece, Why Civilization is Older than We Thought, brings a level of depth and rigor to historical heterodoxy that you rarely find anymore. Burja has also forwarded the “great founder theory” of historical change and formulated the idea of “live players” in social analysis.

    In this episode, Razib asks Burja for his sense of the world landscape in early 2024, revisiting conversations that delve into logistical details of the Russian invasion of Ukraine and the future of Chinese power. Burja continues to be pessimistic about the long-term prospects of European and Ukrainian resistance to a Russian war-machine that is geared toward grinding its way through lengthy battles of attrition. He also asserts that the current bearish attitude toward Chinese power is short-sighted, arguing that Western media in particular understates the technological and economic achievements of the PRC over the last generation. Burja believes that even if the “China bulls” were overly optimistic, the “China bears” go to excess in the opposite direction. Finally, he touches upon his vision for Palladium Magazine, a publication he has long contributed to, and which he now helms.

    On this episode of Unsupervised Learning Razib talks to Steve Hsu, physicist, entrepreneur and public intellectual. Hsu is an Iowan who earned his undergraduate degree from Caltech and his Ph.D. from Berkeley. Later he was a Harvard Junior Fellow, before moving on to professorships at Yale and the University of Oregon, and finally settling down at Michigan State University in 2012. Hsu is founder of Safeweb and Genomic Prediction, and his current focus is on a new AI startup. Between 2012 and 2020, he was vice president for research and graduate studies at Michigan State. Hsu also has a blog, Information Processing, and a podcast, Manifold.

    Razib asks Hsu about where cognitive and behavioral genomics are in 2024, and where they are going. They discuss the reality that while study of educational attainment (EDU) has proceeded relatively far, the study of intelligence itself has been neglected. Hsu outlines the case for why cognitive phenotypes should be studied, even if the topic remains controversial and fraught. They then address the current fad for artificial intelligence, and how emerging companies in the space are going to transform workplace productivity and culture. Hsu contrasts the rapid pace in the advancement in AI with the torpidity of behavioral genomics. Finally, Razib and Hsu discuss changes in academia in the wake of the “Great Awokening” that led to his ouster in 2020 from his role as vice president of research and graduate studies at Michigan State. Hsu talks about how his work in IQ and genetics became weaponized on social media by left-wing graduate students during the George Floyd protests.

  • Murtaza Hussain: Gaza and the global left

    Today Razib talks to Murtaza Hussain about the social, cultural and political context of recent fissures in the US around the conflict in Israel and Gaza. Hussain is a reporter at The Intercept and has his own Substack. They begin their conversation talking about Hussain’s response to the 10/7 Hamas attacks on Israel, and Israel’s subsequent invasion of Gaza. Hussain discusses his bewilderment and disappointment at some commentators who he saw being knee-jerk and tribalistic in their response. He also talks about the generational divides on Israel that have become apparent: while American Boomers and Gen-X tend to support the Jewish state overwhelmingly, while Millennials, and especially Zoomers, are more divided, or perhaps even a pro-Palestinian, perspective. Hussain, a Pakistani Canadian Millennial, though now a naturalized US citizen, does not approach the subject of the Israel/Palestine conflict with a reflexive sympathy for any particular side, but does believe that many Americans are unaware of the broad support that Palestinian nationalism attracts worldwide and especially among the youth.

    Razib and Hussain then discuss the intellectual history that led up the conflict between Hamas, an Islamist movement, and the state of Israel, and how the Palestinian national struggle is positioned within the global Left. They discuss the various connections between Palestinian nationalism in the 1960’s and 1970’s and the Soviet Bloc and Left-wing national liberation movements like the IRA, and how that might impact sympathies of activists. Hussain contends that in many ways the Palestinian liberation movement is a leftover of 20th-century struggles, with the end of apartheid South Africa and the peace accords in Ireland. He outlines the multi-decade relationship both the Palestinians and Israelis have had with the non-aligned movement and postcolonialism. Though today Israel is coded as a Western nation (they participate in Eurovision), Hussain notes that as Prime Minister, David Ben Gurion attempted to send Israeli delegates to the non-aligned Bandung Conference in 1955, a move that was blocked by Egypt.

  • Chris Stringer: human evolution in 2024

    For the first time ever, parents going through IVF can use whole genome sequencing to screen their embryos for hundreds of conditions. Harness the power of genetics to keep your family safe, with Orchid. Check them out at orchidhealth.com.

    On this episode of Unsupervised Learning Razib welcomes back paleoanthropologist Chris Stringer. Affiliated with the Natural History Museum in London, Stringer is the author of African Exodus. The Origins of Modern Humanity, Lone Survivors: How We Came to Be the Only Humans on Earth and  Homo Britannicus - The Incredible Story of Human Life in Britain. A proponent since the 1970’s of the recent African origin of modern humans, he has also for decades been at the center of debates around our species’ relationship to Neanderthals. In the 1980’s, with the rise to prominence of the molecular model of “mtDNA Eve,” Stringer came to the fore as a paleoanthropological voice lending support to the genetic insights that pointed to our African origins. Trained as an anatomist, Stringer asserted that the fossil evidence was in alignment with the mtDNA phylogenies, a contention that has been broadly confirmed over the last five decades. 

    But in 2010, Stringer and other proponents of an “out of Africa” “with replacement” model of recent human origins began to modify their views in response to the mounting evidence of archaic admixture, the introgression of Neanderthal and Denisovan genes into the modern human genome. On this episode, Razib queries Stringer on the state of human evolution from the fossil’s-eye view in 2024. They discuss “Dragon Man,” and whether this is just a fossil of one of the Denisovan populations. Razib also presss Stringer about the diversity of human species in Southeast Asia, and just how many Denisovan populations or “races” might have existed. They also touch on Homo naledi, and the ensuing controversies around naledi-related publications. Razib seeks Stringer’s opinion on different models of African origins for our lineage, from extensive archaic admixture to “African multi-regionalism.” On a more speculative note, they mull over the possibilities for complex societies in the Pleistocene in light of the finds at Göbekli Tepe. With Stinger’s over five decades in the discipline, very few rival his qualifications or capability to provide a bird’s-eye view of where we are in understanding human evolution in 2024.

  • Rob Henderson: foster-kid to Ivy League graduate

    For the first time ever, parents going through IVF can use whole genome sequencing to screen their embryos for hundreds of conditions. Harness the power of genetics to keep your family safe, with Orchid. Check them out at orchidhealth.com.

    On this episode of Unsupervised Learning Razib talks to Rob Henderson, author of the new book Troubled: A Memoir of Foster Care, Family, and Social Class. Henderson is a commentator known for coining the term "luxury beliefs," a tendency among elites to use their beliefs to signal social status, with real-life costs of those beliefs born by non-elites alone. Henderson grew up in California foster homes, before being adopted into a working-class family in Red Bluff, CA. After an academically undistinguished period in high school, he joined the U.S. Air Force straight out of high school, eventually serving a short stint in Germany. While in the military, he was identified as intellectually gifted via standardized tests, and it was during this time that Henderson developed habits that equipped him to become an exemplary airman, and eventually a public intellectual. Along the way, Henderson earned a bachelor’s degree from Yale and a Ph.D. in psychology from Cambridge University. 

    Henderson first came to public prominence with his 2018 New York Times op-ed, Why Being a Foster Child Made Me a Conservative. Later he outlined the concept of luxury beliefs in Quillette, and moved his popular newsletter to Substack. 

    Troubled fleshes out the working-class life experiences that made Henderson who he is today, and how and what sets him apart from other members of the elite-educated “professional-managerial class.” While he was an indifferent student who barely graduated high school, parental expectations prepped Henderson’s classmates for the Ivy League. At the time Henderson was studying at Yale, the median family income of his fellow students was $192,000. In Redding, CA, where he grew up, the median family income was about $65,000. About ten times as many Yale students hailed from the top 1% (19%) than the bottom 20% (2.1%) of family income. Troubled would shock many of Henderson’s Yale classmates, because the economic, social and cultural deprivation and domestic volatility he describes would be so alien and unrelatable. Among the most striking illustrations of how he grew up was Henderson’s perplexity upon being expected to be excited for his first birthday party in his adoptive home. As a former foster child with a winter-break birthday, not only had he never received presents, had a cake or a party. Henderson had literally never been sung “Happy Birthday.” Troubled beings with Henderson’s primary memories of his Korean immigrant mother when he was a toddler. After she was deported, Henderson’s formative years in childhood were spent as a ward of the state, shuffled from foster placement to placement.

    Razib also touches on something that Henderson has discovered in the last few years with consumer genetics. Not knowing who his father was, and clearly not being fully Asian, he had always trusted he was of mixed white and Korean heritage. But a 23andMe test makes it plain that his father was genetically Mexican. Not entirely shocking as Henderson was conceived in Southern California, the genetic test turned him overnight into a “BIPOC” individual, with nearly 20% indigenous American ancestry.
