Black Genetics

A detailed Summary of Black Genetics

Good reason exists to doubt whether genes advantage black Americans at

sport as Jon Entine claims -- the phenomena of the birthday or age cut-off

effect. There is nothing genetic about being born in August rather than

September but it can profoundly change the odds on becoming a professional footballer or tennis player [as well as being treated for mental

sub normality or dyslexia]. The cut-off effect shows that big population

differences need not be genetic since they can arise from apparently small

environmental ones. The mere existence of different numbers of blacks and

white in a sport thus says nothing by itself about genetic advantage [that

requires evidence of correlations between differences at the individual

level between anatomy and physiological sport related traits and actual

sporting success] -- dramatic population differences could equally be due

to apparently insignificant environment factors such as date of birth.

For example, in the English FA premier league over twice as many players,

285 are born in the three months Sept-Nov as the earlier three Jun-Aug,

136. Gene wise they are the same. In a similar way, the Dutch tennis year

starts from the beginning of the calendar year: half its young leag

agency. American Psychologist, 37, 122-147.
