the argument of genetic superiority is pointless.
White people(english/american) have proved their skill in manipulating resources in order to gain prosperity.
But when you consider the fact that they are genetically inferior, you can understand why they are driven to do so.
Also look at England, the land from which most "white" people come from, poor in resources, poor weather. No wonder they got on boats and went to america/canada/africa asap.
African blacks on the other hand lived in a africa which is rich in resources and their stronger genetic traits make life easier.
Therefore the average african in africa does not need to work hard, or fear for their own life from day to day.
From the article: "At that time, around 70,000-80,000 years ago, the early emigrants[The first europeans] would have consisted of small populations lacking in diversity."
This is not news. Everyone knows that genetic diversity implies genetic strength.
So the point is one of your personal opinion. Is it so shocking that a white person may be genetically inferior to a African person?
Is it so shocking that a white person tries harder than an African person?
If it is its probably because of your own personal neuroses more than anything else.
