Steven Pinker on Robert Trivers (1943-2026)

 Pinker writes about how Trivers introduced game-theoretic ideas into evolutionary biology (with genes as the players, and selection into subsequent generations as the payoffs). It's a well written tribute.

The Many Roots of Our Suffering: Reflections on Robert Trivers (1943–2026)  by Steven Pinker 

"Trivers’s contributions belong in the special category of ideas that are obvious once they are explained, yet eluded great minds for ages; simple enough to be stated in a few words, yet with implications that have busied scientists for decades. In an astonishing creative burst from 1971 to 1975, Trivers wrote five seminal essays that invoked patterns of genetic overlap to explain each of the major human relationships: male with female, parent with child, sibling with sibling, partner with partner, and a person with himself or herself."

Human evolution in the last 12,000 years, in PNAS

My loose impression is that, not so long ago, scholars of human evolution discounted recent changes in the human genome, pointing out that maybe the frequency of lactose intolerance had been altered by the domestication of cattle, goats, and sheep, but suggesting that recent changes (i.e. since the invention of agriculture) were rare. This may have been an anti-racism perspective, or it may be that new data have changed this view, but indeed it seems to have changed.

Gene changes in recent milennia offer a window on how human patterns of interaction, regarding food acquisition and preparation, and communal living, may even cause changes in human biology.  

Here's a special feature on the subject, at the PNAS:

Special Feature: The Past 12,000 Years of Behavior, Adaptation, and Evolution Shaped Who We Are Today

"The authors of this Special Feature focus on challenges pertaining to dietary and nutritional quality and adequacy, resource inequality, interpersonal conflict and warfare, climate change, population trends, demographic transitions, migration, mobility, infectious disease and the rise of novel pathogens, and the transformative circumstances of human biology over the last 12,000 years.
