A lot more is coming about the technological transitions, Toba's impact, and climatic context.

Hats off to @ekerdoncuff.bsky.social @priyamoorjani et al.'s outstanding work.

Do read the original paper - doi.org/10.1016/j.ce...

P.S. A lot to wrap up in so little time, but looking fwd. to 2026.

The genetics of South Asia are coming into focus, helping reveal how fast the avalanche of modern humans got going. This region has more Neanderthal genetic variation than any other, and a unique component of Denisovan ancestry never seen before.

Note that @isotopes.bsky.social (with other methods) found that lakes lost hypolimnetic oxygen in three more (far-away) sectors of Greenland around the same time. Oxygen depletion was apparently widespread, in response to a few degrees of summer warming. www.science.org/doi/10.1126/...

One more conceptual layer of the Bretskyan hierarchy: how organisms map on their range and environments or what is the geometry of their movement (as exemplified by dogs and cats).

After two days of reading, thinking, and reading again, I think there are two possible ways to interpret the Yunxian cranium (note that @johnhawks.net and others have already shared some great, and often overlapping ideas): (1/4)

This non #FlintFriday and #FieldworkFriday, I would like to share this mint-fresh Quartzite handaxe from SE India, likely dating back to Middle Pleistocene.

Yes, it hurts to see that broken tip! Still, one of my best find.

I am field-sick, can't wait to go back.

Paper alert 📄

Led by Dr. Anil Devara.

That ~75,000-year-old Toba ash layer (YTT) in India? Our research shows it is not necessary if YTT is isochron! We found YTT at MVP (site) is significantly (40,000 years) younger than ~74ka mark.

Glad to be part of this work!

So much to think about after "Not all that glitters is green" by Verónica Zuccarelli Freire. A powerful reminder that the costs of the energy transition are not shared equally, especially in the #Andes. True climate action requires environmental justice.

"Incredible! This could be a living example of a 'primal throwback,' a manifestation of our ancient, arboreal instincts!"
