@arduq.bsky.social @icarehb.bsky.social What happened to humans who left Africa 100,000 years ago? Here, we bridge genetics and stone tools — Nubian Levallois from Oman dated 109–95 ka, synchronous with gene flow into Neanderthals. Novel stratified evidence. 🔗 doi.org/10.21203/rs....

A failed human expansion out of Africa 100,000 years ago
Early modern humans expanded out of Africa multiple times before 70,000 years ago, yet none of these populations are ancestral to living non-Africans. What caused these dispersals to fail? Here we inv...

#Oman #MSA New paper is OUT! We trace how Dhofar’s MSA shifts from Nubian Levallois cores to the miniaturized Mudayyan industry—highlighting changing technologies along the southern dispersal route out of Africa. @arduq.bsky.social @icarehb.bsky.social link.springer.com/article/10.1...

#MSA #levallois #ICHAJ_25 In Athens on 23rd of September, we’re organising a workshop on the Paleolithic in Jordan at ICHAJ — discussing present and future research in the region. I’ll be presenting on Nubian Levallois in Jordan, with AI helping me create illustrations. @icarehb.bsky.social

Refitted sequence from our newly discovered site, Chessungalane in Mozambique: Early removals caused the pebble to fracture in half due to natural flaws. Knappers then took advantage of the flat fracture to produce bladelets from the narrow surface @icarehb.bsky.social

Levallois Alert ⚠️ Moving beyond classic metric measurements, @eshallinan.bsky.social and @jmcascalheira.bsky.social applied a geometric morphometric approach to Nubian Levallois cores, offering novel insights into shape variability at an inter-regional scale. link.springer.com/article/10.1...

🚨 New paper alert! 🚨 Led by Joana Belmiro, our study on lithic raw materials at Vale Boi reveals that a significant share of chert came from non-local sources, including central Portugal & Andalucía, using macroscopic & petrographic analyses. @icarehb.bsky.social link.springer.com/article/10.1...

Fantastic talk by @eshallinan.bsky.social on Day 1 of the HEIRS Symposium at @icarehb.bsky.social. She explored the history & multiregional nature of Nubian Levallois cores from her 1st open-access NLC dataset. sapientia.ualg.pt/entities/pub.... Stay tuned for more NLC studies SOON!
