A child's skull, almost 140,000 years old, was found in Israel. Researchers believe it shows interbreeding between modern humans and Neanderthals. The skull has both Homo sapiens and Neanderthal traits. CT scans helped in the analysis. Some scientists disagree and want DNA evidence. The discovery could change views on human evolution. It suggests interbreeding occurred earlier than thought.

A nearly 140,000-year-old child's skull found in Skhul Cave, Israel, may show evidence of interbreeding between modern humans and Neanderthals, researchers said in a new study. The partially reconstructed skull, first discovered almost a century ago, belonged to a child believed to be around 3 to 5 years old and was recently examined using modern scanning technology.The research, published in the July-August issue of L'Anthropologie, was led by Anne Dambricourt Malasse at the Institute of Human Paleontology in France. Her team used CT scans to re-analyse the skull, which was previously restored with plaster, limiting scientific study for decades.The braincase of the child displays features common to Homo sapiens, but the mandible — or jawbone — appeared more similar to Neanderthal anatomy. It lacked a chin and showed traits typical of Neanderthals, suggesting a possible mixed lineage."This study is maybe the first that has put the Skhul child's remains on a scientific basis," said John Hawks of the University of Wisconsin-Madison, who was not involved in the research. "The old reconstruction and associated work, literally set in plaster, did not really enable anyone to compare this child with a broader array of recent children to understand its biology."The skull had several missing parts, including much of the facial area and the base. The rest of the bones were in fragments. Using modern technology, the team developed a clearer reconstruction, bringing new attention to the child's features.Not all experts agree with the hybrid theory. Some researchers caution that DNA evidence is needed to confirm the claim. Others believe the observed traits may reflect natural variation within early modern humans."Even if not 1st-generation hybrids, it's certainly possible that the Skhul fossils reflect some gene flow between the 2 populations," said Chris Stringer, a paleoanthropologist at the Natural History Museum in London, who also did not take part in the study. "Overall though, looking at all the material, including the skeletons, the material still primarily aligns with Homo sapiens, in my view."If proven to be a hybrid, the skull would support the idea that modern humans and Neanderthals interbred more often and earlier than previously thought. This could change long-held views about human migration and evolution.Previous studies suggest that genetic exchange between the two species may have occurred about 100,000 years ago. The Skhul child may provide a physical example of this interaction."I have long thought that hybridisations were not viable and I continue to think that they were mostly abortive," said Malasse. "This skeleton reveals that they were nevertheless possible, even though this little girl lived only 5 years."
