I’m excited to share a new publication from my PhD

On-site plant-wax biomarkers + compound-specific isotopes show why relying on bulk δ13C of SOM can mislead in the tropics. Case study: Jwalapuram (S. India).

As I wrap up my doctoral research, I find I have even more questions than when I began—and the picture keeps getting more complex.

Here’s a mint-fresh Levallois point core from the Baghor Coarse Member (~40–50 ka) in the Middle Son Valley (north-central India).

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/...

Aquatic plant wax hydrogen and carbon isotopes in Greenland lakes record shifts in methane cycling during past Holocene warming

δ2H values of aquatic plant wax reveal past Holocene warming led to expanded CH4 cycling in lakes across Greenland.

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)

The phylogenetic position of the Yunxian cranium elucidates the origin of Homo longi and the Denisovans

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.

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.
