Researchers Paola Villa of the University of Colorado Museum and Wil Roebroeks of Leiden University also noted that previous studies compared Neanderthals not to their contemporaries, but to the Homo Sapiens of today. Says Villa, “It would be like comparing the performance of Model T Fords … to the performance of a modern-day Ferrari and conclud(ing) that Henry Ford was cognitively inferior to Enzo Ferrari.”
While concluding general inferiority to Homo Sapiens wasn’t the reason for Neanderthals’ extinction, the study doesn’t offer a single evidential cause. It does suggest genetic depression due to inbreeding and lower fertility rates in Neanderthal/Homo Sapiens offspring could have been a contributor.
