BlackVision said:You're kidding me right? Japan is all mountains. Something like 90% of the land is unliveable. It was an extraordinarily rough terrain to travel through back in the days.
This is true. As shown by the absolute dominance of Africans in track & field.loseyourname said:A continent like Africa is more likely to have speed, strength, dexterity, and such selected for.
Can you tell me how evolution would select high intelligence in a developed nation, and low intelligence in an underdeveloped nation?loseyourname said:The point being that, on a continent with no civilization, high intelligence will be selected for less frequently than on a continent that has high intelligence. A continent like Africa is more likely to have speed, strength, dexterity, and such selected for. You get the picture. You can still be a racist without arguing against all of my points - if that makes a difference.
*This is, of course, in reference to sub-Saharan Africa.

Then why do the Dutch dominate in track ice-skating? You can not blindly connect one thing to the other.BlackVision said:This is true. As shown by the absolute dominance of Africans in track & field.

Nereid said:1) Agriculture and animal husbandry - how did this as the basis of human food supply come about? what were the key factors? where is the scientific research on this topic up to now?
You are talking about homo sapiens here: a social species, someone who can't run surely won't be left on its own. Unless you mean out-running a lion?loseyourname said:Heck, it's even easy to imagine that in an environment where running is so crucial to certain parts of country, that those who can't run would be weeded out of the gene pool pretty quickly.

loseyourname said:You know, I kind of forgot when I was talking about agriculture, but another notable thing about Africa is the lack of domesticable animals. The only one I can think of that is usable is the camel. There are certainly no animals that could be domesticated for food or dairy purposes. The whole point of this, of course, is that agriculture is a precursor to the development of advanced civilizations.
The only parts of Africa amenable to agriculture, without first clearing rainforest, are the north coast and Nile Delta, which of course is where we have found the development of advanced civilizations (Carthage, Alexandria, Memphis, etc.).
Monique said:In civilized areas it stopped, since everyone gets a chance to reproduce.. it would be a degenerate evolution. But ofcourse, now with the mobilization of populations you get a lot of interbreeding.. which is also a kind of evolution?
Monique said:Many dutch of african decent, right: not. Where did you get that information?
Let me tell you why the dutch are so good at track ice-skating: practice. It's almost a national sport: that's why they're so good. Nationally there is a lot of competition of top skaters, this competition leads to high performance. Just to show that there are more arguments to consider than just genes, sure dutch are taller.. it's a balance.

I asked you where you get your information, I get mine from the CIA. The only African country would be just below Spain. Have you ever seen Dutch Maroccan immigrants compete in ice-skating? It's actually the conservative nothern province of Friesland where most ice-skaters come from.plus said:Are you saying that there are no dutch of african descent? The netherlands is a country of immigrants. As such there are many people who are not only of african descent, but people who were born in africa to african parents.
Oh no ice skating! Come on now. You can't compare the strength, stamina, and speed needed for the countless track & fields to ice skating. The more testosterone driven a sport is, the more likely it is that Blacks will dominate. Let's take a sport that requires the most speed. 100M dash. I wonder who's going to win the Olympics this year in this category. Let's take a sport that requires the most stamina. Marathons. Once again, who would win here? Let's take a sport that requires the most strength. Boxing. Again, who dominates this? Ice skating. Yeah ok. What are you going to bring up next? Golf?Monique said:Then why do the Dutch dominate in track ice-skating? You can not blindly connect one thing to the other.
To say that genetics has absolutely no role in the dominance of Kenyans in marathons would be completely inscientific.loseyourname said:One thing I do know is why Kenyans dominate distance running. They train constantly, from a very young age.
If running was crucial for survival in the history of the Kenyan people then yes, those who can't run would have been weeded out of the gene pool.Heck, it's even easy to imagine that in an environment where running is so crucial to certain parts of country, that those who can't run would be weeded out of the gene pool pretty quickly.
How different is track ice-skating from 100m dash? huh?BlackVision said:Ice skating. Yeah ok. What are you going to bring up next? Golf?
It's a winter sport for one. The evolutionary development of Africans was not in cold regions that had ample ice and snow. Second, there seems to be a genuine lack of interest for ice skating among blacks. Something that isn't true for whites in black dominated sports. E.g. Basketball, boxing. Where the fans are predominately white, while the players are predominately black. There is also an extraordinarily lack of blacks in upper latitudes today where ice will actually exist.Monique said:How different is track ice-skating from 100m dash? huh?
I think you mean 'unscientific'.BlackVision said:To say that genetics has absolutely no role in the dominance of Kenyans in marathons would be completely inscientific.
The key statistic would be the incidence of mortality before puberty or late adolescence. However, 'child under 5' mortality rates would give at least a lower estimate; IIRC there are still quite a few countries where these are >100 per 1000 live births ... given that these numbers are national averages, the rates in rural and remote areas in these countries will surely be considerably higher.plus said:Even in non civilised areas, almost every one too gets the chance to reproduce. It is just once in a while that people starve. Overwhelmingly the people in the developing world are benefiting in this regard, hence the population explosions in these areas.
Don't make me dig up your spelling errors.Nereid said:I think you mean 'unscientific'.
No one is saying training does not matter. The argument is against people who attempt to say it's 100% environment.The differences in performance between the elite athletes of any background are razor thin, <0.1%; the fact that if Mark Spitz (sp? - US winner of 7 gold medals for swimming in the 1972 Olympics) were to try for a place on the US *women's* swimming team today - in his favourite distance - he wouldn't even qualify speaks volumes about the role of training, diet, etc.
Either you use the muscles or you don't, either you sprint on ice or on gravel.. there's not much evolution that goes into that.BlackVision said:It's a winter sport for one. The evolutionary development of Africans was not in cold regions that had ample ice and snow.
But who would argue that it's 100% environment? To pick just one example - the variation in athletic ability among the ~20,000 healthy adults aged 15 to 45 of any mid-sized town anywhere on the planet is enormous; it's certainly far, far greater than the variation between the elite athletes from different countries. Further, no amount of training of those 20,000 will reduce the variation so that it's comparable to that between 20,000 elite athletes; the back of my admittedly very small envelope suggests at least an OOM difference, maybe two.BlackVision said:No one is saying training does not matter.

How do you know Turkheimer et al didn't take this into account? From the description that Evo provided, it would seem likely that they did: "Biometric analyses were conducted using models allowing for components attributable to the additive effects of genotype, shared environment, and nonshared environment to interact with socioeconomic status (SES) measured as a continuous variable."BlackVision said:Because many if not most people in high SES got there due to their high intelligence.Nereid said:If so, I confess to being confused by your comment BV, how is 'a person with higher intelligence will have higher probability to have a job that will give him higher SES' (in modern US society; assume it's consistent with research results for the moment) relevant to the study which Evo referenced?Because you can't directly cross SES without taking into consideration that a person's probability to be in high SES is increased with higher intelligence. It would be like crossing college graduates with non college graduates and going, "see college graduates have a higher IQ by 10 points." Which will probably end up to be true, but attempting to argue that it's because that person went to college that he has an IQ surplus rather than the fact that it's his intelligence that got him to college. It working backwards.Nereid said:In particular, how is the study's method flawed by not taking this into consideration?
Nereid said:Seems to me that, without knowing the details of the models Turkheimer et al used, there's no way to make your 'flawed study' claim.
Ice skating and jogging requires different muscles. Go on a skating rink and pretend to jog and see how well it works. Go on a pavement and pretend to glide from side to side with your shoes. See if it's the same. You should easily be able to notice they are different movements that require different things. If they were the same, the world's best runner would also be the world's best skater. And vice versa. It does not work that way.Monique said:Either you use the muscles or you don't, either you sprint on ice or on gravel.. there's not much evolution that goes into that.
Oh yeah the fact that ice is absolutely foreign in the development of African evolution. Yeah that has no impact at all.Evo said:I have to agree with Monique. If you are saying that blacks are stronger, more athletic, able to run faster, etc... Whether it is on ice or not should make no difference, should it?
Believe me they didn't. They would show specifically how they did it. They would go on for pages and pages just explaining this one aspect as it is a difficult aspect to factor in. And if it did, Evo would be all over me about it. But she's not. This study is nothing new. As soon as the Bell Curve was released, they attempted this exact same method to try to counter the Bell Curve. And since then, I'm seen numerous studies all doing the same thing. It didn't work then, it doesn't work now.Nereid said:How do you know Turkheimer et al didn't take this into account?

Or, to repeat the part of my original post which you conveniently omitted:
Seems to me unless you can prove this study weighed the fact that the more intelligent a person is the higher probability there is that a person will be in higher SES, this study is void correct? If you're going to try to use this study, seems like it would be you that would need to prove something.Seems to me that, without knowing the details of the models Turkheimer et al used, there's no way to make your 'flawed study' claim.
You don't seem to get it, why would the dutch have an evolutionary advantage to be able to track ice-skate better over other nations?BlackVision said:Oh yeah the fact that ice is absolutely foreign in the development of African evolution. Yeah that has no impact at all.
It's been proven infinite times that Blacks are better runners. I am yet to see a study that states otherwise. If you have one please by all means share it with us.
