A Science study finds Neanderthal men and anatomically modern human women interbred more than the reverse, as Neanderthal DNA is disproportionately found on the human X chromosome. The result points to sex-biased gene flow and raises questions about the social dynamics behind these ancient matings, which researchers are looking to explore further.
Scientists from the University of Edinburgh have discovered that a region of Neanderthal DNA enhances the activity of a gene involved in jaw development, providing insights into how facial features like larger jaws evolved in Neanderthals compared to modern humans.
New discoveries along Portugal's Algarve coast have revealed the first fossilized Neanderthal footprints in the region, dating back around 78,000 to 82,000 years. These footprints provide direct evidence of Neanderthal behavior, movement, and social structure, indicating they explored coastal environments and had a diverse diet including deer, horses, and marine resources. This challenges previous ideas about Neanderthal ecology and highlights their adaptability to coastal habitats.
Recent discoveries confirm that Neanderthals created cave art over 64,000 years ago, predating modern humans' arrival in Europe, including hand stencils, geometric shapes, and other markings, challenging previous assumptions about their cognitive abilities.
Researchers analyzed bone fragments from the Starosele site in Crimea, identifying Neanderthal DNA and linking European and Siberian Neanderthal populations, suggesting migration routes across Eurasia around 45,000 years ago, facilitated by favorable paleoclimate corridors.
A new study suggests that genetic differences in red blood cell function between Neanderthals and modern humans may have caused reproductive issues in hybrids, potentially hastening Neanderthal extinction by reducing their reproductive success over generations.
Scientists believe it may be possible to bring back Neanderthals within 20 years using advanced genetic engineering, but this raises significant ethical, scientific, and legal concerns, including the potential for unregulated private ventures and the moral implications of creating a new human-like species.
Scientists are close to potentially bringing back Neanderthals within 20 years using advanced genetic technologies like CRISPR, but this raises significant ethical, legal, and practical concerns, including the feasibility of the process, the well-being of any resurrected individuals, and the moral implications of creating a new human-like species. Most experts agree that such efforts are currently unwise and ethically problematic, emphasizing the importance of preserving existing human and animal species instead.
Scientists have found evidence at Skhul Cave in Israel suggesting that interbreeding between Neanderthals and Homo sapiens occurred around 140,000 years ago, predating previous estimates by nearly 100,000 years, indicating a long period of coexistence and genetic mingling between the two species.
Scientists sequenced the genome of Thorin, a 42,000-year-old Neanderthal found in France, revealing that this individual was genetically isolated from other Neanderthal groups and showed no interbreeding with modern humans, challenging previous assumptions about Neanderthal populations and human extinction.

Scientists sequenced the genome of Thorin, a 42,000-year-old Neanderthal found in France, revealing that this lineage remained isolated from other Neanderthals and modern humans for thousands of years, challenging previous assumptions about interbreeding and population interactions in human history.
Scientists sequenced the genome of Thorin, a 42,000-year-old Neanderthal from France, revealing that this lineage remained isolated from other Neanderthals and modern humans for thousands of years, challenging previous assumptions about interbreeding and population interactions in human history.
Scientists in Israel discovered the oldest known mixed human-Neanderthal fossil, a 140,000-year-old child's skeleton showing traits of both species, providing evidence of interbreeding and social ties between Neanderthals and early Homo sapiens in the region.
A study found that a genetic variant inherited from Neanderthals reduces the activity of a key muscle enzyme, AMPD1, by up to 80% in mice and 25% in lab proteins. This variant, present in 2-8% of Europeans, impairs muscle performance but is generally tolerated, and carriers are less likely to reach elite athletic levels. The research highlights the impact of ancient DNA on modern human physiology and performance.
