That sounds like contrived rubbish me. Yes we can pluck a dozen Germans off the street and you might find 5 different eye colours, 6 hair colours, a range of 30 IQ points, a priest and a thug, and over a foot between the tallest and shortest.
Yet show me a picture of any of them and I am confident I could roughly point to the region in Europe where their ancestors have toiled for the last thousand generations. Put them and a dozen Congolese in a group and a 5 year old could easily separate them into their two respective racial groups.
There is clearly a common genetic 'core' among people of the same racial group. There may be much diversity within it, too, but to use that to deny the existence of this shared heritage is downright subversive and disingenuous.
