Article Synopsis
- Neanderthal genomes from various Eurasian sites reveal that late European Neanderthals likely formed a single, interconnected population with little internal structure.
- The discovery of "Thorin," a late Neanderthal from Grotte Mandrin in France, includes his unique dental fossils and provides insights into their culture around 50,000 to 42,000 years ago.
- Thorin's genome indicates he was genetically isolated for about 50,000 years from other late Neanderthals, suggesting distinct lineage differences that could help explain their eventual disappearance.
Article Synopsis
- Researchers analyzed genetic data from 13 Neanderthals found in two caves in southern Siberia to better understand their social organization.
- The study revealed family relationships among some individuals and suggested they were part of a small community, indicated by high levels of genetic similarity.
- Findings show that female Neanderthals likely migrated between communities, as evidenced by the lower diversity in Y-chromosome data compared to mitochondrial data.
Denisova Cave, a Pleistocene site in the Altai Mountains of Russian Siberia, has yielded significant fossil and lithic evidence for the Pleistocene in Northern Asia. Abundant animal and human bones have been discovered at the site, however, these tend to be highly fragmented, necessitating new approaches to identifying important hominin and faunal fossils. Here we report the results for 8253 bone fragments using ZooMS.

This means that small amounts of contaminating carbon can wield a great influence over accuracy unless they are fully removed. The site of Kabazi II in the Crimea is important because radiocarbon dates previously obtained from bones in archaeological horizons that date to the Western Crimean Mousterian (WCM) are surprisingly young.
