In 2006, however, Dr. William Aiken, president of the Jamaica Urological Society, offered in the Jamaica Gleaner a reductionist theory that has the potential to explain many racial differences beyond sprinting:
"I wish to propose a hypothesis that addresses not only the aspect of Jamaica's raw athletic talent, but also encompasses an explanation of seemingly diverse phenomena as our high incidence of prostate cancer (one study found it to be by far the highest in the world at 304 / 100,000 men / year), our high crime rate (murder capital of the world status earlier this year), our high road traffic accident and fatality rate, and our alleged high levels of promiscuity.
"What do these seemingly disparate phenomena, characteristic of Jamaican life, have in common? On close examination these phenomena are manifestations of high levels of aggressiveness and drive, high libidos, highly efficient muscles from persons of lean body mass and black ethnicity.
"On closer scrutiny all of these phenomena are either related to high circulating levels of testosterone or alternatively to high levels of responsiveness of testosterone receptors to circulating testosterone. It has already been shown that the testosterone receptors of blacks are different genetically to those of whites and this difference confers increased responsiveness to testosterone."[The athletic prowess of Jamaicans, November 22, 2006]
Occam's Razor suggests that Aiken's theory should be considered carefully.
Yes Virginia, Race is real.
And demographics have consequences...
