Neanderthals:
These were the first human like fossils found. The Neanderthals existed throughout western Europe and across into the near east and central Asia from about 100,000 years ago to 40,000 or 35,000 years ago, depending on the precise locality. There are, striking structural distinctions between Neanderthals and modern humans. Although, the posture, range of movements and manipulation skills were the same in Neanderthals as in modem humans, the skeleton was substantially more robust. Neanderthal's brain was on average slightly larger than normal for modern humans, measuring about 1400 cm3. The large brain size could be corrasponding to the more robust musculature. Neanderthals were proficient hunters, skilled tool makers and they used hides for protecting their bodies. For the first time in human history, ritual burial became common.
