[QUOTE]Originally posted by Doug M: [QB] The problem I have with "Negrito" is what I said, all of the aboriginal populations of Asia were not short with kinky hair. Again, the Papuans aren't short but they do have kinky hair. While the Australian Aborigines are not short but they have straight hair. All these populations are directly tied to the original OOA migrations due to isolation, but they all look physically different. And all of them had to pass through Sundaland, so that means the original OOA populations passing through this area could not have all been little short people with kinky hair. You also see this across the Pacific in recent history as many of those populations were also dark skinned with straight hair while others had curly or kinky hair while others were lighter skinned with similar features. I am not sure what is so hard to understand about that. Some were tall, some were short, some had round eyes, some had almond eyes, some had big noses, some had narrow noses, some had big lips, some had thin lips, some had straight hair, some had culry hair and some had kinky hair. That is what I mean by these populations were already diverse and over time under genetic selection pressure, these features evolved into those distributed across Asia today. The only thing these isolated populations tell us across the board is that all of those OOA groups were diverse. Now, you see the same thing regarding Northern Asians in cases like the Ainu of Japan. This is what I mean by skin color not being relevant to my point. At some point in time there were Northern Asians with round eyes, alongside those with almond eyes, just like there were some with generalized Euarasian features (western/central Eurasian) and others with more pronounced "Mongoloid" features. But over time under selection pressure those so-called "Mongoloid" features won out over the others among light skinned Northern Asians. Meaning that the original dispersed smaller clusters of populations in Asia would have been more diverse than they are today. And the diversity decreased due to bottlenecks, environmental and sexual selection. It is the same process that affected all of these groups whether the isolated aboriginal tribes or those "basal East Asians", except what happened in North Asia happened on a larger scale due to the population boom during the neolithic. That doesn't mean those so-called "mongoloid" features weren't present prior to that, but just that they were part of a much more diverse set of features across Asia and the "Negritoes" are subsets of that diversity not representative of all those groups.
