    I think people are a little over sensitive on the race issue. Sure were all human and like Clinton stated and was quoted in the article, all humans are 99.9% similar in genetic structure. However, we're also 98.4% genetically related with chimpanzees, so obviously 0.01 can make a obvious difference. If you think about it, being physically different between races makes sense. Different ethnicities adapted to different climates, geographics, and ways of lifes. Whites do tend to dominate in wrestling (although there are exceptions obviously) just like blacks tend to dominate races (although, once again there are exceptions). To say that its racsist to think or believe in this is just uneducated and possibly showing fear of being labeled a rascist, which wouldn't come as a suprise in a society that is, I believe, too politically correct. Political correctness sometimes drives people away from common sense. When was the last time you saw a white running back in the NFL? How about a starting white running back? This isn't rascist, and I'm sure a white could start at running back, but its probabally harder naturally for him to become one. All in all the article is a good read and I hope it enlightens some to the fact that while we're all human, we do differ genetically and more than likely are more naturally prone to certain sports.

    If your going to try and prove me wrong, feel free, but please go easy on me. I'm only 16 and stating my opinion. Sorry for the long read :)

    I don't buy it. Sure there are differences, but they are so small that they are negligible compared to the only difference that matters - motivation.

    If African genetics is important for being a running back in the NFL, why isn't the NFL dominated by Africans rather than African-Americans who are mixed (European/African genes)?

    If you think African genes give you an advantage in sports, then you probably also believe that European genes give you an advantage in cognitive pursuits?

    Alls I knows is the English have bad teeth, the French smell bad, the Germans make some nice cars, and the Italians have beautiful women.

    Well 1.5% diffence would normally be considered small. Unfortunately, that's also the difference between a human and a chimpanzee. If you didn't, read the article, its very good. And I agree that motivation definately matters. However, I would say that if a African has better genetics to become a running back. If two people work the same, the person with the better genetics will become better. I don't think African genes give an advantage in all sports, just some. I also believe European-descent gives advantages to other sports, as well as Asians to others, and so on. Also, a possible reason that its dominated by African-Americans instead of just Africans is a) Not many Africans play football. (I do believe its a rather American sport :), b) African-Americans are descended from Africa and I doubt 200-400 years of climate, geographical, and ways of life change the basis of your genetics much. Also, not all African-Americans are both European and African genetically. In fact, I doubt you could name more than ten iin professional sports (NFL, NBA, NHL, MLB). I'm sure their are some, but none that I can think of so enlighten me.

    You must remember that we had thousands of years, at the least, to adapt to our surroundings. 400 years is nothing compared to 20,000. But hey, I'm just a 16 year old. Unfortuately, your disagreeing with a professor of genetics as well. While your entitled to your opinion, I also am. I had a source giving some reasonable opinions, backed by high standing members in the field which we are discussing. Take it or leave it as it is. But I think that answers your question as to why Africans don't dominate a sport they do not play, although African-Americans (who have a greater chance of playing the sport than your average African) do tend to dominate the speed positions.

    I also do believe that Europeans have certain mental strengths that Asians, Africans, and/or any other race don't have as naturally of (again with exceptions). I also think that Africans/Asians/whomever also have certain strengths in terms of mental capability. Maybe Asians are better at abstract thinking more naturally than someone from European descent, while a African may be better naturally at factual retainment, while Europeans are possibly better at mechanical knowledge. These are just examples, I doubt that those are correct but just give a basis to my reasoning that I believe different races have different strengths and weaknesses, both physically and mentally.

    Now that I've reread your response, I doubt you read the article, or even my post very thouroughly. So please, do. I never stated that having African descent made you superior in every athletic activity, or any at all. It just gave you more natural tools to work with for certain endeavors. I believe the same applies for all ethnicities.

    Actually you are only partially correct - although increased muscle mass does present a problem in terms of weight/density the fact is that a lot of swimmers (especially short course) are excellent physical specimens and have significant levels of muscle mass already. In addition E.African people who are genetically very slight of frame still do not perform at all well in swimming tests.

    Aside form the issue of slow/fast twitch fibre balance another problem re: black people and swimming is to do with the erector spinae musculature - which in order to facilitate efficient upright running (basically what from an evloutionary perspective the black race has specialised in) - is quite rigid and inflexible, this creates significant problems from a swimmers perspective who generate a lot of power from the back region as a whole and especially regarding certain strokes like Butterfly where a sort of whiplash movement is used to generate power and movement. The issue of erector spinae also partially goes towards explaining the minimal numbers of W and E Africans in gymnastics - a sport where flexibility throughout the whole human musculature is essential.

    Finally because of their evolutionary bioas towards colder climates Orientals and Caucasians carry a slightly higher % of adipose tissue around the mid torso area (in colder climates the extra fat is vital for insulation and the maintaing of a high functioning immune system) - this has a useful side effect in that it provides buoyancy in a water environment.

    It seems that you just post in Heavyweights and Wasteland.

    These are your first posts in Training? No?

    Also, your vocabulary is terrible.

    So what?? Ive several relevant posts in the main forum - what the fuck does it matter where they get posted!?!

    My vocab is far from terrible - I understand you are an American but just so you know I come from England, you know that place where the English language comes from?!?! Some of my terminlogy may be more colloquial London & there might be the odd typo (after all im no secretary) - but please dont lecture me on how to speak my own language....... after all i dont lecture you on how to be an ignorant, fat, warmongering dumbass do I?!?!?

    I've always wanted a Brit to call me a "daft prick".

    Will you?

    Man I was agreeing with you, but now you've insulted me. And btw, just because the English language came from England does not mean your an expert in it. That's like saying America is the best at running businesses because we were the first main country to use capitalism. While fat, ignorant, warmongering dumbasses might applly to some Americans, it also is ignorant seeing as America generally takes first as a team in most Olympics, attracts and attracted some of the most intelligent people in the world to come here to learn/teach, and was a pascifist nation for much of WWII. Just because the U.S. recently has declared war does not mean we're warmongering, nor fat or ignorant. Most of the people on this forum are hardly fat or ignorant.

    Don't base your thoughts what you see in the media, and remember who landed on the moon in 1966. England has just recentlly CIRCLED the moon with a unmanned space ship, so America is rather ahead in technology.

    And to those saying this contradicts what I said earlier about races possibly being more naturally gifted mentally and physically in different fields, it doesn't. It could be possible for European/European descent to be more naturally predisposed to violence, you must have motivation (even if it is less of it) and, as earlier stated, its just naturally having a tendancy toward it, mentally or physcially. Nothing in our genetics writes in stone what we will be able to do mentally or physically, just gives us a edge in some things.

    All I see is somebody needs more critical thinking over here...


    here's my 2 cents worth...

    genetics and fiber type may determine if you have an advantage or disadvantage but what you make of it will still determine the outcome in the end...

    I've seen guys who are predominantly slow-twitch to good in an event suited for fast-twitch guys and vice versa..

    And quit the racism here. its just makes some points moot and make some people look dumber than they really are...

    ignorance is curable, stupidity is terminal

    That insult is particularly well used in Liverpool and Manchester - in London we prefer 'wanker', 'tosser' or 'twat'....

    I agree 100%

    I doubt that they were competing on a high level (nationals, Olympics, international events) but I also agree that it could happen

    Saying a race is possibly more naturally gifted physcically and mentally at certain events/areas isn't racsist, its possibly true.

    "About 30% of black Americans who take DNA tests to determine their African lineage prove to be descended from Europeans on their father's side, says Rick Kittles, scientific director of African Ancestry, a Washington, D.C., company that began offering the tests in 2003. Almost all black Americans whom Kittles has tested descended from African women, he says."

    You are arguing that genetics are very important, but you include in your reasoning a non-genetic reason.

    This is exactly what I was arguing. Genetic differences may make some difference, but they are nothing compared to differences of motivation and opportunity.
