Why is AAR (Amino Acid Racemisation; by implication #palaeoproteomics) so often overlooked for #geochronology?

The new issue of PaleoAnthropology is now online! 📢

It includes the Special Issue 'What’s in a Name? Late Middle and Early Late Pleistocene Hominin Systematics'

The cover features the article 'Revisiting the Anatomy of the Florisbad Hominin Cranium' by Balzeau et al.

COMING SOON! We’re delighted to share that our executive report, bringing together experts on regenerative agriculture and resilient food systems will be released soon.

We hosted ‘The Voices of the Global South on the Anthropocene’ Conference in June 2024 at the Max-Planck-Institute of Geoanthropoloy Jena, Germany.

You can read more about this event, and the important discussions we engaged in, both below and at the link in our bio!

Our aim is to bring together diverse voices and perspectives, incorporating palaeoecology, archaeology and traditional knowledge, to address pressing challenges relating to climate change, pollution and biodiversity loss.

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

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).

#newpreprint: "Climate Shaped the Global Population Structure of Leopards and their Extinction in Europe": www.biorxiv.org/content/10.1...! Leopards are charming big cats but there are many mysteries around them. Thread 🧵

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.

Deep history from the genomes of India People carrying Neanderthal mixture entered the subcontinent after 50,000 years ago, meeting Denisovans

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.

Jane Goodall, primatologist and friend to chimpanzees, dies at 91 She used her global fame to draw attention to the plight of dwindling chimpanzee populations and, more broadly, to the perils of environmental destruction.

Very sad. One of the world's great human beings.

So excited to announce the lineup of speakers here @heasvienna.bsky.social for the 2025/6 academic year! We have some outstanding speakers for our three seminar series in Archaelogical Science, Ancient Genomics and Human Evolution & the Palaeolithic. All hybrid! Register now at HEAS.at

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.

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/...

Ridge densities for canids and felids for the nine landscapes in which at least one species from each clade was tracked together.

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).

The phylogenetic position of the Yunxian cranium elucidates the origin of Homo longi and the Denisovans Diverse forms of Homo coexisted during the Middle Pleistocene. Whether these fossil humans represent different species or clades is debated. The ~1-million-year-old Yunxian 2 fossil from China is impo...

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.
