No evidence that hominin dispersal across Eurasia was part of a wider turnover in mammal distributions
Wow. This is an amazing cover of Butthole Surfers' song "Pepper."
New paper alert. My new article just published in Quaternary Science Reviews, "Revolution, modernity, and the dispersal of Homo sapiens beyond Africa". www.sciencedirect.com/science/arti...
Our new paper exploring the measurement of complexity in tools - the result of significant and ongoing work, including that which emerged from our Complexity in Lithics Conference!

Awhile back I meet the brilliant Jenni French & and now been lucky to collab on a project w/ her for the last ~3 yrs. Along with Somaye Khaksar & @anthrofuentes.bsky.social our 1st project paper is out, on origins & development of mobile containers (1/n) 🧪 🧺

Yeah, I need to check this out. Sounds amazing. That's a lot of live music that guy experienced. He must have been out every night of his life.
🚨 Publication alert🚨 Early humans in South Africa were quarrying stone as long as 220,000 years ago at the site of Jojosi @natcomms.nature.com - specialized, long-term use of a source of a raw material source in Stone Age Africa: Read the paper #openaccess here www.nature.com/articles/s41...
Figure 2 from Monson et al (2026). Figure 2. Allometric scaling of endocranial volume and body mass in extant primates and Plio-Pleistocene hominids. The figure displays a bivariate plot with two regression slopes through known fossil hominin species and the extant apes. It shows that the early hominin species Ardipithecus ramidus and Australopithecus anamensis may have had a relationship between body mass and endocranial volume (a proxy for brain size) more similar to extant apes with relatively small brains. In contrast, hominins after 3 million years ago show larger endocranial volumes relative to their inferred body mass.

"Both small-bodied Homo floresiensis and Homo naledi have endocranial volumes (ECVs) that are consistent with their body size given the scaling relationship that characterizes genus Homo."
Diagram of shoulder anatomy, but both the anatomy and the labels are wrong and very obviously AI-generated.
There are so many no-good, terribly bad, wrong, AI-generated anatomical diagrams out there. Here's one I found on the website of an actual clinic in Minnesota. Yikes. Be careful out there.

Phylogenetic tree showing the evolutionary relationships of living and fossil apes including the newly described fossil Masripithecus moghraensis.
A phylogenetic tree? There's not one in this news piece, but the formal paper in Science has one.

This tracks--I've always actively avoided poshness!
If we value logic and rigor in our language, then I hope we can influence an evolution back to that as the convention--at least in formal settings, as obviously I ain't that formal on bsky.
I don't know who needs to hear this (besides a lot of humans writing stuff), but logically speaking, something can't be "very unique" or "not very unique" or "highly unique" or "exceptionally unique" or "somewhat unique." Uniqueness indicates singularity. Something is unique or it ain't.
Of the Denver bands over the years that have had some national notoriety, 16 Horsepower is probably my favorite.
Early punk, new wave, and power pop from Colo-rady including Jello Biafra's first band (Healers).
Snowy and 30F here in Denver today but looking to hit 70-80s (21-27C) by the time of #AABA2026. All the same, Colorado says "pack layers."
