Why are Black runners so much faster than whitey?

trendlover,

one more comment, your biologist says something I find to be quite odd

The argument against hypothesis 2 is not naive, however it is naive to think that the selective pressures on human populations are anywhere close to the highly engineered selective pressures you find in animal breeding....


....This is in contrast with intelligence: single genetic variants with large beneficial effects on intelligence are probably much, much harder to come by, because any large genetic change is likely to screw up something as complex as cognition. To get significant differences in intelligence between populations, my biological intuition is that you would need many small but non-negligible changes that together add up to something large enough to make a difference in the population distribution of intelligence.

I am a dog guy, people can breed intelligence in just a few generations. Every dog person knows border collies are the smartest breed, it didn't take long to get them there. There are also large differences in other breeds, so to say that intelligence is something that is difficult to evolve... I don't know about that.

Wolves are much smarter than ordinary dogs, even though they can breed with each other. It didn't take much to dumb them down apparently. It shows what happens when selective pressures dissappear... what does that say about us in the welfare state? Our DNA is supposedly 96% chimpanzee (another argument against the we 'are mostly the same')....look out below.

Oh no , (rcg must be hearing dog air raid sirens about now )you didn't just use the "porch monkey" attack did you ?

notice also that your link says

He says the idea of race genetics is not ruled out, we have been saying that all along.

---------------------------------------------------------------------------------


notice my link say this too



"Given what we know about human population history, and the likelihood that a very complex trait like intelligence is controlled by many genes with pleiotropic effects, I find it implausible that significant differences in intelligence between populations have arisen over the past 50k years."


snip

"Something similar appears to have happened with skin pigmentation in human populations that migrated out of Africa: single variants with a large effect on skin color was able to quickly reach high frequency in populations that moved out of Africa.

This is in contrast with intelligence: single genetic variants with large beneficial effects on intelligence are probably much, much harder to come by, because any large genetic change is likely to screw up something as complex as cognition. To get significant differences in intelligence between populations, my biological intuition is that you would need many small but non-negligible changes that together add up to something large enough to make a difference in the population distribution of intelligence."

And YOU said this.

Quote from Mav88:

Scientifically it makes sense that if one major organ like the skin and a genetic feature like muscle structure is different, then so it is very possible that another organ like the brain is different. But that's where liberal religion says no. So its ok that they are better athletically, but there is no difference cognitively by decree according to liberal gospel. Most of us know better. [/B]

Quote from PHOENIX TRADING:

I'm sorry but the facts of reality tell a different tale as far as I understand it.
With equal opportunity the group with the lower scoring cognitive skills are likely to fall further and further behind in successive generations (if heritability is the primary mode of transference).

I could be wrong but I see very little evidence that environment plays a large role in transmission of cognitive ability to offspring.(reason being is the female is born with all the eggs she will ever produce so oops virtually no chance for environment to enhance the genes already present).

But of course what do I know I'm supposedly only an ignorant racist redneck who refuses to engage in group think.

---------------------------------------------------------------------------------

For example Mav88, look what phoenix talk about.
Is this determinism he talk about?

Let's don't forget that was in response to ricters reply to mav below.

Quote from Ricter:

The important thing is that there are "black" people who are stronger, faster, more coordinated, more talented, more hardworking, and more intelliegent than Mav88. So, with equal opportunity and time, their offspring will, on average, advance further still, leaving Mav88's offspring far behind (on average).

You know what I see? I see many people of the politics thread always talking about American welfare system keep minoritys poor. The Republicnas say the democratic welfare keep them on the reservation because they tell minoritys you can not be successful with no help from welfare. But then some people like YOU want to say is some kind of genes that make some people never able to succeed. So I do not like politics, but really which of the party in USA, republican or Democrat really think some people are inferior? If I have to bet today, I will bet Republican.

Really! Name one so I can read about this person.

(based on your posting history)
If I carefully addressed your concerns you would still fail to understand, so I guess I'm passing the buck.
