Razib Khan's Unsupervised Learning Razib Khan

 


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.

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?

 


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.

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. 

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.
