French site sparks Neandertal debate

Around 36,000 years ago, Neandertals and people lived side by side in southwestern France for at least a millennium, according to a newly assembled chronology of ancient occupations there. Paul Mellars of Cambridge University in England and his coworkers say that their work supports the controversial view that shortly before dying out about 28,000 years ago, Neandertals borrowed toolmaking techniques from neighboring Homo sapiens.
