Boomerang made from mammoth tusk with 5 cm scale
A boomerang made from mammoth ivory, from Obลazowa Cave, Poland. Dating to around 40,000 years ago, the object was shaped and well-used, with signs of polish in the areas where a right-handed person would have handled and thrown it.

Saw another article today headlined, "The Real Paleo Diet". Is there any more hackneyed concept at this point? Do people still click on this?
Ethics in Paleoanthropology ๐ฆด
Human remains are ancestors, not just objects of study. Ethical research prioritizes dignity, provenance, and repatriation.
We prefer โdeep historyโ over โprehistoricโ because it centers the human experience.
What are your thoughts on displaying remains in museums? ๐๏ธ๐

Rock art: The original GPS? ๐บ๏ธ
In deep history, symbolic marks were more than just artโthey were data. They mapped resources and paths across landscapes, serving as a survival tool for our ancestors.

Rock art = The Original GPS. ๐ฟ๐บ๏ธ
Forget "pretty pictures"โthis was high-stakes data storage. From marking water to tracking game, rock art served as a "distributed memory system" for our ancestors.

Exciting news from Rowtor, Derbyshire! Anna Clark discovered rare animal engravings in early 2025, verified by experts. The figures include a female cervid with her calf and an extinct aurochs. These finds hint at a deep Mesolithic connection, beyond the famous Bronze Age art. #RockArt
I'm pretty excited about a new study of the African influence on Neanderthal X chromosomes. It's because a pattern of dispersal of early modern people based on matrilineal kin networks makes a lot of sense.

Were Neanderthals the first curators? ๐ฆด Evidence shows they collected rare fossils & crystals with no survival use. This points to a deep aesthetic & symbolic life.

๐ฆด The Homo naledi debate is still ROARING.
Was it intentional burial and rock art, or just natural cave accumulation? The gap between "Cave of Bones" and recent peer-reviewed critiques is wide.

Hey @sethchagi.bsky.social ๐
Is cave art actually a "hard drive"? ๐ง New research in PNAS shows 40,000-year-old signs have the same statistical entropy as Proto-Cuneiform. Weโre decoding a 40k-year-old "cloud."

Ever wonder how ancient artists made their paint stay on stone for 40,000+ years? ๐จ
Experimental archaeology helps us decode the "recipe" of deep history. From grinding ochre in shells to testing application methods, we're recreating the ancient toolkit. ๐ชจโจ

New research in PNAS (Bentz & Dutkiewicz, 2026) shows Upper Paleolithic signs were structured systems for encoding info. Our ancestors were "writing" on ivory and stone way before Sumer.

Iโve been trying to understand this fossil for more than twenty years. The femur and ulna are the first real clues about its locomotion, but specialists who have studied the bones all disagree about what they say. I took a deep dive to understand the big picture.

Packing for Italy ๐ฎ๐น residency has me thinking about "Planning Depth" & mobile toolkits. New Substack on the cognitive evolution of the carry-on is live!
Read the article: open.substack.com/pub/deephist...
Then, Iโll return to California for 10 days, before returning to Portugal for two weeks and finally heading to Indonesia for almost a month.
Iโve always dreamed of traveling, and itโs finally happening!
My residency permit finally arrived, allowing me to embark on a big trip to Isernia, Italy, for a meeting of all the IMPQ students on my birthday.
The trip lasts 10 days, followed by a conference in Macao, Portugal, for another 10 days.
Live tomorrow, Tuesday the 24th at 3:30 PM MT! ๐ฆด Iโm teaching the next generation about Neanderthals & deep history on โThe Childrenโs Hour.โ Catch us on one of 300 stations across 7 countries! ๐ป Listen here: www.childrenshour.org/stations/
