Thanks for the link Blam. Describes me to a “T” - or most of it anyway.

I know that there are hints of a “bottle neck” in the human population in the ancient past. Probably, Ice Age climate change caused humans to drop down to less than 10K and perhaps as few as a few hundred world wide.

A smaller base population in the colder climates of Europe would cause less diversity there. Some have suggested that this also caused selection for higher intelligence and other cultural and genetic changes in order to survive the near extintion level conditions.

This is esoteric and highly speculative stuff. Trying to read into it is tough, and not exactly responsible science.

However, I think it is interesting to bring up that we all evolved from an original African population.

For a moment, I thought this thread was another story about black leftist college professors still promoting the “White Man stole mathematics from the Black Man” theory. What a relief!

I agree, the premise is not good.

“What is interesting to note is that the agricultural technology spread much further than the people who first ‘invented’ it.”

Well, my family’s E3b made it to Aberdeenshire, Scotland. Maybe the majority of agriculture E3b people died off in one of the plagues or by the hands of the Vikings.

It depends on how well the study was structured and conducted.

SMALL SAMPLE sizes

INCREASE

the significance of what’s found.

It’s greatly easy, all other things being equal, to find subtle changes at levels of statistical significance in large samples.

Whether those statistically significant findings from large samples mean anything or not is often dubious.

Ultimately the human species originated in Africa.

The discussions center around the when and how.

Nope. They're still there. There never was very many of them.

yeah, that was the first thing I noticed, then I saw the leap they made from African-American and European American to strictly Europeans. The test group is too small, there is no control group, and the group tested cannot be guaranteed 100% African or 100% European. As far as I can see it’s all wishful thinking on someone’s part.
