Africa was been proven to have excellent resources for successful agriculture ... after it was colonized
*sigh* Yeah. And not so good after the European farmers were kicked out.
City dwelling Africans proved no better farmers than Cambodian "intellectuals"...
And now that the whites have voluntarily left, or been pressured into conceding power (South Africa), the countries are either regressing into acute poverty and violence, or the resources are being utilised by the Chinese, who have zero “white guilt” and don’t give a damn about PC or world opinion, and won’t over-exert themselves to show benevolence or shoulder the “Asian man’s burden”.
The Bantu, all 600 some odd groupings expanded throughout Central and Southern Africa during the last 5,000 years because they were very good farmers. Colonists need workers for their farms or mines and the Bantu filled the bill. That has been in the last few hundred years and disrupted the culture of eons. Even before that, they were in some cases the slaves, in other the suppliers of slaves to primarily the Arabs / Muslims. So you have a bit of disruption of cultures there. In general, the British were less disruptive of the Africans’ society and were willing to educate and train Africans. With the notable and large exception of Zimbabwe (Rodesia) British colonies worldwide have fared better than others.
The point being, I’ve been reading Wade and tend to agree with some of the hypothesis he presents but I think the divisions and differences he proposes are based on groups segregated from others by geography and segregation (the Jews and Roma). Race seems too large an aggregation to be meaningfuly delt with. History throws so many variables in the what may be good for survival today might doom you tommarrow.
I started to go there;) The Romans, Greeks, Britons, etc., imposed laws that were retained by their colonies even after “liberation”, (they also created babies before leaving).
So, assimilation, integration and intermarriage can enhance progeny and pass the best genes to the next generation(s) .
