I can understand Spud’s irritation with Mates who has become something of a master of the idiotic comment where race is concerned, whilst Scara simply becomes increasingly irrelevant with every post he contributes
That apart, it’s an interesting question. I thought that the following reply, on a thread dealing with this very issue, was pretty intelligent
‘As an ex-competitve swimmer who has spent most of his adult life working as a professional diver in Africa I think I can contribute an objective slant to this debate.
Firstly Africa and its inhabitants are as diverse as Europe, it just happens that their skin colour is predominately darker and it is somewhat ethnocentric to see Africa as a single entity. There are ethnic differences around the world Spaniards and Norwegians Kenyans and Cameroonians, the variety in humans is enormous. I worked with many West African divers who were very good swimmers. Not "trained " swimmers, in the competitive sense to which the original question referred, but they certainly had the natural ability to have been good. However they’re a minority who are exposed to swimming. This is where the economic factors come in to play. There are 150 million Nigerians. I am sure if the percentage exposed to competitive swimming was equivalent to that of, say Australia, the number who turned out to be great swimmers would probably be proportionately the same.
I have taught a number of Africans to swim and only once have i met some one who was negatively buoyant. He was extremely athletic and had very low body fat, we over came this through technique.
One of the previous commentators refers to financial incentive this is also a major factor, better to be a Michael Jordan than a Mark Spitz. As western society becomes more cosmopolitan the differences will I suspect even out and people will see things more based on the individual, for example Serena Williams would at one time have been seen as having the classical build for a fly swimmer, I doubt she would have excelled on a road bike though or for that matter as a marathon runner. How would Bradly Wiggins fare as a water polo player? Probably not well.
The eugenics approach is dangerous because it refuses the diversity that is prevalent in all races. I am sure it is possible to prove that some people with more skin pigment have an athletic advantage over some with less, but take a different selection and I am sure you could equally prove the opposite. Equality of opportunity will, I am sure, produce an even distribution of success.
