2932114YS Our Brothers' Keepers: Homo Sapiens ~~~~

Q
Despite the benefits of fire, 150.000 years ago humans were still marginal creatures. Now they could scare away lions, warm themselves during cold nights, and burn down the occasional forest! Yet counting all species together, there were still no more than perhaps a million humans living between the Indonesian archipelago and the Iberian peninsula, a mere blip on the ecological radar.

Our own species, Homo sapiens, was already present on the world stage, but so far it was just minding its own business in a corner of Africa? We don't know exactly where and when animals that can be classified as Sapiens FÌRST evolved from some earlier type of humans, but most scientists agree that by. 150.000 years ago, East Africa was populated by SAPIENS that looked just like us! If one of them turned up in a modern morgue, the local pathologist would notice almost nothing peculiar? Thanks to the blessings of fire, they had already smaller teeth & jaws than their ancestors, whereas they had massive brains, equal in size to ours!

Scientists also agree that about 70.000 years ago, Sapiens from East Africa spread into the Arabian peninsula, and from there they quickly overran the entire Eurasian landmass? When homo sapiens landed in Arabia, most of Eirasia was already settled by other humans! What happened to thèm? There are two conflicting theories. The 'Interbreeding Theory' tells a story of attraction, sex and mingling. As the African immigrants spread around the world, they bred with other human populations, and people today are the outcome of this interbreeding.

For example, when Sapiens reached the Middle East & Europe, they encountered the Neanderthals. These humans were more muscular than Sapiens, had larger brains, and were better adapted to cold climes. They used tools and fire, we're good hunters, and apparently took care of their sick & infirm. (Archeologists have discovered the bones of Neanderthals who lived for many years with severe physical handicaps, evidence that they were cared ff by their relatives.) Neanderthals are often depicted in caricatures as the archetypical brutish & stupid 'cave peopld', but recent evidence has changed their image.
