Story summary

A groundbreaking study of a 75,000-year-old Neanderthal skull from Iraq reveals a potential connection between Neanderthal DNA and Chiari malformation type I, a condition causing brain protrusion into the spine. Strikingly, modern humans with this disorder share similar skull shapes with Neanderthals, paving the way for future genetic screening to identify at-risk individuals.
