Early Neanderthals, whose ancestors were probably Homo erectus, which is an evolutionary offshoot of Homo erectus, left behind very few and far between residues. When this kind of shape in an independent, too difficult to tell: about 250 000-500 000 years ago. However, the characteristics that distinguish it from modern man, Neanderthals were: stocky, with prominent brow ridges, a larger skull, but no chin. The most impressive feature of the Neanderthal skull - a huge gap in the middle of the front part, suggestive of a disproportionately large nose. As it developed such features it remains a mystery, although it has been suggested that the big nose - the result of adaptation to the cold climate, to the inhaled cold air time to warm up. After all, the Neanderthals, after all, lived in the high, northern latitudes, unlike other human species remaining in the tropics. They inhabited the lands that survived more than one glacial and interglacial periods. In isolated areas with ever-changing environmental conditions the Neanderthals evolved on its own path, different from the way other types of prehistoric man.
