There
is a certain level of genetics involved. If your culture stimulates the right side of the brain, evolution will follow suit and also enhance the ease at which future generations develope the right side of the brain. Humans needed opposable thumbs, so we evolved with them. Humans did not need hands for feet, so we evolved out of that. Culture and environment play a large role in the genetic advancements of certain races.
Noting these truthful aspects of races is not an evil form of racism, but saying hat all janitors are mexican and all white rappers are gay
is evil racism. For that, I shall bap you! *baps*
Hmm... Well language as we know it as only existed for a few millenia, I'm not really an expert on the subject but I don't think that's going to have too much of a factor on brain development, evolution takes longer than that. It's true we are somewhat different in appearance from people thousands of years ago, but I think that's mostly an issue of different living conditions (enough food so that growth is not stunted, better medicine, etc.).
Ignoring that issue for a moment, if you are basing your 'race plays a factor' card on people evolving based on their language, then we're back to cultural issues as opposed to genetic ones. Language is entirely arbitrary and unnatural, so you're not so much talking about an inherent superiority or inferiority for certain activities based on race, but on the part that history and culture plays. Not to forget that language is in such a rapid state of flux that it seems doubtful that such a system would develop in any case. Our language was runic in nature until about 1400 years ago.
