Neanderthals

Neanderthals are an extinct group of archaic humans who lived in Eurasia until about 40,000 years ago. The exact timing of their split from modern humans is unclear, with studies suggesting a divergence between 315,000 and 800,000 years ago. Neanderthals are known from numerous fossils, particularly from after 130,000 years ago, and their extinction is attributed to various factors including demographic decline, competitive replacement, interbreeding with modern humans, climate change, disease, or a combination of these factors. They possessed sophisticated technology, including the Mousterian stone-tool industry, and were capable of complex behaviors such as cooking, clothing, and symbolic thought. Neanderthals had a robust build and proportionally shorter limbs, which may have been adaptations for conserving heat in a cold climate or for sprinting in a warmer landscape.learn more on wikipedia
