Why do North American Natives look more caucasoid and South American Natives look more mongoloid?

Answer 1

Nobody knows exactly. However, both North and South American Indians originally came from Asia. Asia is a huge continent with lots of genetic diversity and there was probably even more genetic diversity there 8,000 to 20,000 years ago than there is today.

The old idea that Proto-American Indians came across the Bering Strait in a single migration has been largely dismissed by modern linguists and anthropologists. They believe that ancestral American Indians originated in different parts of Asia, from Turkey to the Pacific, and came over at different times - in "waves" - ranging from as long ago as 20,000 years ago to as little as 8,000 years ago.

The first migration from Asia about 20,000 years ago brought over so-called "Clovis Man" who probably eventually became extinct. The last migration out of Asia, about 8,000 years ago brought over the ancestors of the modern Salish, Athabaskan and Uto-Aztecan (Mexican) Indians.

Modern day Caucasians and Mongoloids appeared relatively late. Most likely, the differences between the two races were more blurred when the first American Indians arrived in the Western Hemisphere.

Answer 2

There's actually a recent theory (that when investigated seems to make sense enough) that both early Europeans and Asians made their way to America, with Asians working their way down the west coast and Europeans working their way across the large glacieral sheet of the North Atlantic. The theory states that the Europeans could have made skin boats and traveled and lived along the glacieral sheet in a way similar to "eskimos" (for lack of a better word). That might be an explanation for why Northern Natives look a little more caucasian than Southern Natives.

I'm not saying this theory is right, just throwing it out there.

Answer 3

North American natives don't look caucasoid. Where on earth did you get an idea like that?

Answer 4

And what does Mongoloid mean? And is Caucasoid a word?

Its also a function of interbreeding in the past few hundred years. Those who bore children of olive-skinned Europeans would have darker skin than those the English and French.

Answer 5

north american natives don't look caucasoid.

Answer 6

There are different populations that came over at different times. Perhaps the Indians you know are partially white but there are definitely difference among the natives..
