I read the article. You quoted the only good part in the entire article.
The final paragraph is total junk:
You are very critical of racism.
Yes. We are all much closely related than we ever expected. Racism is not only socially divisive, but also scientifically incorrect. We are all descendants of people who lived in Africa recently. We are all Africans under the skin.
What a complete lie ! Under the skin we are radically different. Anthropologists can tell the race of an individual just by the jawbone in most cases. Any dentist can tell the race just by looking at teeth.
"Racism is not only socially divisive, but also scientifically incorrect."
The most casual observer can see massive differences between the races.
Geez, the junk that masquerades as scientific knowledge.
(Dr. Spencer Wells is either a fool, or a lying hypocrite !)
