The ERC Project MATRIX explores one of the big questions in our past: how Neanderthals disappeared as modern humans spread across Europe. Meet the team behind it and learn more about our research on sediments, ancient DNA, proteins, lipids & human evolution

Mechanical experiments are in progress at TraCEr by @eduardopaixao.bsky.social, testing the impact of different raw materials on the crushing of raw tubers.
This study is part of broader research on early human behavior and percussive tool use at the Acheulean site of Melka Wakena, Ethiopia

Thousands of ancient bronze offerings… deliberately smashed. Why? We’re on a mission to find out – and now we have 3 more years to do it. 💪

Humans may have been making tools from whale bones up to 20,000 years ago, says OA research in @natcomms.nature.com. Their discovery helps broaden understanding of early human use of whale remains and provides snapshot of ancient whale ecology: spklr.io/63328BERzp

Did you ever ask why people used so many different rocks in their tasks?
If you had this question in your mind, go and check my new paper with my colleagues. dx.plos.org/10.1371/jour...

We were thrilled to have Areti, a PhD student from Leiden University, at TraCEr for the last three weeks to document post-depositional modifications on flint before and after freeze-thaw cycles using the LSCM. Hope to see you soon again, Areti!

New paper in #ScienceAdvances led by @paleomonrepos.bsky.social and @unileiden.bsky.social on #Neanderthal adaptation 125ka years ago at Neumark-Nord 2, Germany. Our study shows large-scale grease rendering thousands of years earlier than previously thought: www.science.org/doi/10.1126/... 🦣🧪🏺
Large-scale processing of within-bone nutrients by Neanderthals, 125,000 years ago
Neanderthals intensively processed a minimum of 172 large mammals for grease and marrow fat, 125,000 years ago.
