Explanation:

Neanderthals are an extinct species or subspecies of archaic humans who lived in Eurasia until about 40,000 years ago. They probably went extinct due to competition with or extermination by immigrating modern humans or due to great climatic.

These features are often explained as adaptations to conserve heat in a cold climate, but are more likely adaptations for sprinting in the warmer, forested landscape that Neanderthals often inhabited.
