If you want top musicians, you have to have students taking music degrees.

That includes the ones who didn't go to university, but took guitar lessons or were inspired by a school music teacher, rely on top producers or session musicians who acquired their skills on a music degree, etc etc etc.

The new Wiley journal review system is an absolute nightmare. Editorial assistants have been replaced by a clunky, AI-enabled website that makes it harder to find and invite reviewers. Associate editor workloads have increased. I'm not convinced the invitations to reviewers are even going through.

Looking forward to the 2025 Rocky Mountain Biological Anthropology Association meeting this Saturday (Oct 4th) on the CU Boulder campus. RMBAA has developed into a nice regional association with a great community. Come on out if you're in the Denver area. #RMBAA2025

Sadly, I never met Jane Goodall. But the tributes from anthropology friends speak volumes. So many folks were inspired by her to pursue our science, which connects humanity to the living world. Whatever's beyond, I hope it involves her embraced in the nature she worked so hard to get us to care for.

New paper out! This was a fun collaboration with Dr. Trent Holliday, Libby Cowgill, and Scott Maddux to work up a broad review on Neanderthal cold adaptations ranging from technological to physiological. This is a good one for teaching.

We referred to our collaboration as the "Coldies but Goodies"
Neandertal Cold Adaptation: Technological, Anatomical, and Physiological Responses to Cold Stress in One of Our Closest Fossil Relatives
Neandertals occupied western Eurasia for over 100 000 years, repeatedly enduring climates that ranged from seasonally cold to glacial. This paper reexamines the question of Neandertal cold adaptation...

📢 Come join us! Penn State Anthropology is hiring *two tenure-track assistant professors*, one in human reproductive ecology and one in archaeology. Here are just a few reasons why working at Penn State is awesome:

New research finds that 12,000-year-old camel art in Saudi Arabia’s Nefud Desert once marked ancient water sources.

Hunter-gatherers may have used the ephemeral water bodies to penetrate deeper into the barren landscape.

New for @science.org 🧪🏺
Prehistoric camel art pointed to precious water sources in the Arabian Desert
Hunter-gatherers may have used the engravings to find water 12,000 years ago

If correct ("Homo longi" sits within a clade that includes H. sapiens & Denisovans to the exclusion of Neanderthals), this supports the hypothesis of a deep divergence of the H. sapiens & Neanderthal lineages (at least 0.94 -1.10 million years ago based on age of Yunxian). #paleoanthropology 🧪
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...

Counter to how I've always known and taught it, the levator veli palatini attaches solely to the pharyngotympanic ("Eustachian") tube & not the inferior aspect of the petrous temporal bone. I love that there are still little mysteries to solve in human anatomy. #anated #anatomy #anatomyeducation

For centuries, anatomists debated true origin of levator veli palatini—vital for speech & swallowing. Researchers found it arises from cartilaginous Eustachian tube not petrous bone, reshaping understanding of vocal tract evolution

Jayde also collaborated with our team to identify tiny shards of glass (cryptotephra) from a different volcano at the late Pleistocene sites of Arma Veirana & Riparo Bombrini in northwestern Italy. She's a topnotch pro. I highly recommend her if anyone is looking to do this work at other sites. 🏺

How did the ostrich cross the ocean? This fossil holds clues!

This is the holotype of Lithornis promiscuus at the Smithsonian National Museum of Natural History. This heron-sized bird lived in a swampy floodplain in Paleocene Wyoming. #FossilFriday thread (1/4)
