Does Evolution give us shape of eyes, lips, breadth of nose and skin color?

But ';NOT'; intelligence I find it very odd that intelligence is the only thing evolution will not touch? Hummmm I guess mother nature is Politically correct too





';there is no firm reason to anticipate that the intellectual capacities of peoples geographically separated in their evolution should prove to have evolved identically. Our wanting to reserve equal powers of reason as some universal heritage of humanity will not be enough to make it so';





do you agree or disagree? Also does reality change cause you agree or disagree?Does Evolution give us shape of eyes, lips, breadth of nose and skin color?
Your retarded. Everyone knows Chinese people are smart.





Why TF would reality change, numbnuts?Does Evolution give us shape of eyes, lips, breadth of nose and skin color?
Not even wild animals have evolved the same mentally. That's why mothers eat their young. To thin the herd of the slow and weak. You need to keep the breed strong.





Besides, do you know how boring it would be if we were all the same? Granted you won't see too many rednecks hanging out in Manhattan on Wall Street but then again you don't see too many 3 piece hand made suits at the tractor pulls.





The only way that my reality has ever changed was by ingesting too many illegal chemicals or money related.
Go to R%26amp;S if you want to talk about stuff like this.
There's genotype and then there's phenotype. Just because a trait is heritable (influenced by genes) does not mean that's it's not also influenced by the environment.

Intelligence is controlled by thousands of genes - many more than the other traits you mention. Intelligence is also variably defined, difficult to measure, and culturally relative.

Any environmental influences or developmental issues that affect any of the genes that control intelligence will alter the phenotypic expression in spite of the genetic potential. In Africa, over 20,000 children die every day from starvation. Many of the children that do survive have still suffered from malnutrition during a vitally important period of brain development, including the time spent in their mother's womb. These children will never live up to their genetic potential - we've probably lost several Einstein's just because we don't have the will to feed starving babies. War zones present a similar scenario.

Environmental chemicals are also a huge developmental factor that is largely ignored by industrial societies. We have released thousands of synthetic chemicals into our environment and have no idea what their affects are on our own offspring; most of what we do know is bad, but we don't have the will to limit this practice.

';There is no firm reason to anticipate that the intellectual capacities of peoples geographically separated in their evolution should prove to have evolved identically.'; This may be true. In fact there are also genes that control stupidity, a trait that may sometimes offer evolutionary benefits, and these certainly interact in complex ways with intelligence genes.

But there's also every reason to suspect that the intellectual capacities of peoples geographically separated - and subject to variable degrees of environmental stress - will produce variable powers of reasoning regardless of their genetic potential, and measuring the resulting individual intelligences will not mean a thing unless these environmental factors are taking into account.





The world has never been a level playing field, but our modern society has further polluted the possibility of teasing out the truths concerning intelligence and genotype from data that is subject to such varied phenotypic expression. As it is, I鈥檓 not sure your question has any real-world relevance.
Well it does in some ways.


';black'; people are said to have a better sense of smell (and taste) than white people, possible because of the wider nasal cavities.





Though I don't know if you would consider that to make them ';more intelligent';.








Everything evolves to suit it's lifestyle best. That's why animals in cold regions have thick fur and animals in hot areas have less dense fur.





Humans are generally similar enough in lifestyle that their capacities for math and language are roughly equivalent as far as we can tell but then not everyone is pushed to their furthest limits. So ';intelligence'; is relative to what is best for survival and that can vary with environment.





Someone in a strongly religious area is said to be ';intelligent'; if they believe in God because that's the social standard there where as they would be called a dumbass amongst a strong atheist community.





Someone who is good at hunting wild game is said to be more intelligent if that's what another community depends upon for survival. Though in an office environment it would be considered useless and absurd.





Certain physical characteristics do lead to increased mental ability but we are able to understand ';why'; with humans. A person who is colorblind is not considered ';stupid'; they're considered ';disabled';.





My opinion has the potential to change the perception of reality but things will always be as they are regardless of how we see them.
