Tonguez said:From Asia Modern humans reached Australia about 40000 yrs bp, the Solomon Islands were settledt 25000 years bp and another stream reached America about 15000 yrs bp. The Asian populations went south first because of the more fertile conditions - the area north (ie siberia) being cold tundra until after the last glaciations. (NB there is also evidence of Melanesian populations reaching America as early as 30000 years bp - but its still controversial)
Oh and Neolithic Agriculture hit America in about 2000BC
You are quite right. Humanity spread out quite fast, and that is one of the clearest testaments to our species fertily and adaptability. They mainly kept to somewhat warm locations.
As for early colonisation of the American continents. Most of the so called evidence is very flimsy and circumstantial. There have also been reports of fire places from 50.000 BP, but there are also very suspect. There is no clear evidence of early colonisation. Personally I do not have any problems with an earlier colonisation, but if there were people in America at such an early date, why did they not spread more out and why do we not have more evidence?
Tonguez said:As I understand it Homo Sapiens being an africa species simply had it easier than neanderthals. During the Ice Age whilst Europe was a cold land cursed with ice Africa floursihed with extensive fertile savanna and wetlands teeming with animals and thus people. Those people (Homo Sapiens) were able to settle down and form villages and even agriculture (there is evidence of grain cultivation and cattle herding). It was also these people who about 90000 years bp spread north eventually reaching Europe (and Asia) where they encountered Neanderthals and lived with them for approx 10000 years
You are quite right. It is true that Homo Sapiens and Homo Neandertalensis lived side by side during several thousand years, it was not in all of Europe. As Homo Sapiens spread into Europe, Homo Neandertalensis was slowly "pushed back" (how is still open to interpretation). It was quite late (in comparison to other locations) before Homo Sapiens really dominated Europe.
Early agriculture is discussed alot too. It is generally acknowledges that it was not until 9000 - 8000 BC that we developed agriculture. There are alot of evidence that it had started earlier, but one of few things that archaeologist agree on, is that a neolithic culture has to have domesticated plants and/or animals. This means that the species has to have undergone some change in comparison to its wild version. This is seen first in the Middle East in the period 9000 - 8000 BC.
