I love this. Dissection is such an important part of the curriculum, as we need health providers to understand the amazing variation and history written into the bodies of their patients. Here, the daughter of a donor writes beautifully about her experience of grief and honoring her mother's wishes.

Fantastic opportunity for the right person, very important collections, wonderful staff, inspiring students, and tremendous scientific opportunities.

NEW PALEO JOB!! The Evolutionary Studies Institute (ESI) in Johannesburg is hiring a Director. Famous for human origins, dinosaur evolution, and most importantly (😅) Permo-Triassic tetrapods, this is a huge opportunity to lead one of the world’s greatest paleo institutes. Please share!

BREAKING NEWS The Royal Swedish Academy of Sciences has decided to award the 2026 #NobelPrize in Physics to Francis Halzen “for decisive contributions to the IceCube Neutrino Observatory and the discovery of high-energy neutrinos of astrophysical origin.”

Rather than filtering based on an overstretched handful of editors and peer reviewers who cannot possibly have the time to get deep enough into every paper to know if it is actually helpful in terms of generating new understanding of the works, we need a post publication collaborative approach.

“In broad strokes, the modern human population evolved from a merger of two ancient groups around 300,000 years ago, roughly 80% from one, and 20% from the other. The uniformity of this signal in all living populations suggests that it was a true formative event.” www.johnhawks.net/p/modern-hum...

An oldie but goody for #fossilfriday, KMN-ER 406. This skull of Paranthropus boisei is one of my all-time favorites! It's one solid mass: dense and heavy. Now curated beautifully by Tom Mukhuyu at National Museums of Kenya.

Had a great email question on superarchaic gene flow this morning and the possible implications of human chromosome fusion. I did address in this post on the fusion of chromosome 2: Introgression and gene flow often happens despite differences in karyotype. www.johnhawks.net/p/when-did-h...

johnhawks.netWhen did human chromosome 2 fuse?More and more, it looks like this event happened shortly before a million years ago, in the common ancestors of Neandertal, Denisovan, and African ancestral humans.

Interesting twist in a new paper: Introgression deserts aren't actually deserted. “Our findings suggest that ghost ancestry is often present in previously defined archaic deserts, providing additional context to putative Homo sapiens–specific selection.” www.science.org/doi/10.1126/...

8/ we have objectively, empirically *improved knowledge* in a very anthropological way: by showing that reductionism misdescribes reality. That, I think, is what makes these critics uncomfortable; they like certainty and universal dicta, and anthropology says “it depends”.

Academia is not a zero-sum game. You can do rigorous scientific work AND care about the problems of other people. Wild, I know. Not that I expect the authors of the vanderbilt report to have ever helped anyone with their scholarship.

Susan Greenberg@susanhgreenberg.insidehighered.com

Vanderbilt University commissioned a report on the state of humanities scholarship. Now some of the scholars accused of producing work driven by political ideology rather than the pursuit of truth are fighting back. @emmawhitford.bsky.social has the scoop. www.insidehighered.com/news/faculty...

In response to the report, I want to make an observation followed by an argument. My observation is this: The contents of this report are totally disconnected from the scholarship they're talking about. These authors didn't engage in good faith with the fields they're discussing.

Next week Sunday May 24, I'll be in Kraków, Poland at the 2026 Copernicus Festival. I'll be talking about "A new history of Homo sapiens", deep time Africa and the intricate history of mixture underlying humanity's origin. Free and open to the public! copernicusfestival.com/events/nowa-...

Nice explainer of the H. erectus protein study, by @killgrove.bsky.social, with helpful commentary from @johnhawks.net on complex overlaps of ancient human groups in Africa, Europe & Asia. “Scientists used to call it ‘the muddle in the Middle Pleistocene’; now we know that muddling is just mixing.”🧪

I think this is because Science is sadly no longer publishing technical responses to articles bsky.app/profile/wsde...

William DeWitt@wsdewitt.github.io

It was announced in this editorial that technical-comment-and-rebuttals will be ceased in favor of what they call “eLetters”, which are not indexed in the scholarly record, and appear to be nothing more than blog-style comments that can't include substantive technical content like figures/data/math.
