Today, Razib talks about a new paper, : Understanding the history of admixture events and population size changes leading to modern humans is central to human evolutionary genetics. Here we introduce a coalescence-based hidden Markov model, cobraa, that explicitly represents an ancestral population split and rejoin, and demonstrate its application on simulated and real data across multiple species. Using cobraa, we present evidence for an extended period of structure in the history of all modern humans, in which two ancestral populations that diverged ~1.5 million years ago came...

On this episode of Unsupervised Learning Razib comments on a new paper in Nature,. Here is the abstract: Although it is one of the most arid regions today, the Sahara Desert was a green savannah during the African Humid Period (AHP) between 14,500 and 5,000 years before present, with water bodies promoting human occupation and the spread of pastoralism in the middle Holocene epoch1. DNA rarely preserves well in this region, limiting knowledge of the Sahara’s genetic history and demographic past. Here we report ancient genomic data from the Central Sahara, obtained from...

info_outlineOn this episode of Unsupervised Learning Razib talks to Conn Carroll, the author of Sex and the Citizen: How the Assault on Marriage Is Destroying Democracy. Caroll is currently an editor for the Washington Examiner, but previously he was the communications director for Senator Mike Lee of Utah, an assistant director at the Heritage Foundation, White House correspondent for Townhall.com and a reporter at National Journal. Carroll wrote Sex and the Citizen in response to what he felt was misleading and biased reporting in the mainstream media on the origins and implications of marriage and monogamy.
Razib asks Carroll how he refutes the ideas presented in Christopher Ryan and Cacilda Jethá’s Sex at Dawn, which argues that prehistoric humans were non-monogamous. Carroll outlines the current mainstream thinking in evolutionary anthropology and primatology, and all the biological reasons that indicate that Homo sapiens is far more monogamous than our common chimpanzee and gorilla cousins, most clearly in our reduced sexual dimorphism.
But while our hunter-gatherer past was defined by monogamy, Sex and the Citizen argues that the rise of agriculture resulted in the explosion of polygamy, as high status males in societies defined by incredible inequality began to monopolize access to women, culminating in the explosion of Y chromosomal “star phylogenies,” where supermale lineages exploded all over Eurasian 4,000 years ago. Carroll then explains that the Romans and Greeks took steps toward enforcing monogamy as a legal institution, and Christianity introduced the idea of sexual fidelity upon men. After Christianity popularized egalitarian monogamous marriage, Sex and the Citizen follows in Joe Henrich’s wake in The WEIRDest People in the World: How the West Became Psychologically Peculiar and Particularly Prosperous. Carroll discusses the Catholic Church’s strict policies on incest and adoption, which destroyed the power of elite related clans in the West, and hastened the emergence of the Western European marriage norm of independent and separate nuclear families, rather than extended families as the primary unit of kinship in society.
In the second half of Sex and the Citizen Carroll addresses the social history and policy changes in relation to marriage in the US. While Western European societies took a significant step away from familialism, Carroll explains that American marriage was even more individualistic and radical, as nuclear families spread out to the frontier, away from their extended kin networks. He also contextualizes the rise of the 1950’s nuclear family, which some scholars have argued was an aberration in American history. Carroll argues that actually it was an extension of earlier American norms, but the rise of the wage-based capitalist economy allowed for couples to set up separate households earlier in their lives. Carroll concludes the discussion outlining the 1970’s policy changes in welfare provision that discouraged marriage, noting the decline of the institution across American society over the last 60 years, and how government policy might reverse it.
