Archaeologists at Marathousa 1 in southern Greece unearthed two wooden tools dating to about 430,000 years ago, including an 81 cm alder digging stick—the oldest handheld wooden tool known—suggesting Homo heidelbergensis or early Neanderthals used wood alongside stone tools in a glacial lakeshore habitat and expanding our view of early technology.
A large-scale whole-genome study of over 3,200 Japanese individuals uncovers a previously hidden third ancestral group linked to the Emishi in northeastern Japan, supporting a tripartite origin for modern Japan and revealing persistent Neanderthal and Denisovan DNA with potential health implications.
The Amud 7 Neanderthal infant from Amud Cave in Israel—dated to about 51,000–56,000 years ago and the most complete Neanderthal infant skeleton found—shows Neanderthal babies grew their bodies faster than modern human babies, with rapid somatic growth outpacing tooth development (teeth suggested an age closer to six months, vs. about 13.7 months for bone growth). This accelerated early growth, including larger skulls, likely reflects an evolutionary strategy to adapt to harsh environments, with growth trajectories eventually converging with Homo sapiens.
A 7,500-year-old skull from Hahnöfersand, once thought to be a Neanderthal–modern human hybrid, has been reclassified as fully consistent with Homo sapiens and dated to the Mesolithic. New morphometric analysis shows no intermediate traits, overturning decades of hybrid interpretation and reshaping understanding of post‑Ice Age human variation in Europe.
A remarkably complete Neanderthal infant fossil, Amud 7, dating to 51,000–56,000 years ago, shows a dental age of about 5–6 months but skeletal and brain development like a 12–14‑month‑old, revealing a rapid early growth pattern and an age paradox that appears biologically rooted; findings, based on 111 bones and published in Current Biology, suggest Neanderthal infants grew quickly and began early solid foods around five to six months, with similar patterns seen in other Neanderthal children.
Analysis of Amud 7, a six‑month‑old Neanderthal infant from Israel, shows the baby’s body and brain were already the size of a modern one‑year‑old (about 880 cc), indicating Neanderthals grew up much faster in the first years of life. The rapid early growth was likely fueled by high caloric needs and early solid-food introduction around five–six months, helping Neanderthals reach physical independence in harsh Ice Age conditions. This pattern appears consistent across other Neanderthal infants, though by about age seven their developmental trajectory converges with Homo sapiens, suggesting differences in life-history timing rather than overall brain/body size. The findings point to regulatory differences in shared genes guiding development rather than a wholly separate genetic blueprint.
Researchers at Neumark-Nord, Germany, uncovered a multi-step Neanderthal bone-grease operation dating to about 125,000 years ago, including breaking bones, grinding fragments, and boiling them to render fat from at least 172 mammals. The site suggests deliberate, landscape-scale resource management with caching and transport of carcass parts, revealing advanced subsistence planning well before modern industry.
A Science study using ancient DNA finds that interbreeding between Neanderthals and modern humans favored male Neanderthals and female humans, inferred from X-chromosome inheritance patterns across the genomes.
A new genetic analysis finds Neanderthal DNA is underrepresented on the human X chromosome while a human fingerprint appears on the Neanderthal X, suggesting that ancient mating favored human females with Neanderthal males. The pattern is attributed to mating behavior and social interactions rather than purely Darwinian survival, though other explanations aren’t ruled out.
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.
