Ancient Humans
Researchers have discovered ancient human DNA on cave walls and rock art in Spain and Portugal, marking the first such finding on prehistoric paintings. The breakthrough could eventually help identify individual artists from thousands of years ago.

A 59,000-year-old tooth from a Siberian cave reveals that Neanderthals drilled into cavities to treat decay. The discovery pushes back the origins of dentistry by tens of thousands of years. Researchers identified clear marks from stone tools on the molar.
A detailed analysis of a well-preserved Neanderthal nasal cavity has revealed that their large noses were not shaped by cold-climate adaptations as previously thought. The findings from the Altamura Man specimen challenge long-held ideas about Neanderthal evolution. Researchers used advanced imaging to examine internal structures inside the skull.

A new study suggests that interbreeding between Neanderthals and Homo sapiens created a genetic incompatibility that increased pregnancy failure risks in hybrid mothers, potentially contributing to Neanderthals' extinction. This mismatch involved differences in the PIEZO1 gene affecting oxygen transport in blood. The finding could explain the absence of Neanderthal mitochondrial DNA in modern humans.
