I would like more convincing retorts than this (and I have seen some when during my research). Well, go and do some research on the Internet and find information to prove me wrong.
The brain is largely determined by genetics. If it wasn't then a chimpanzee would be able to do everything that a human can do, for example. Chimpanzees have almost the same genetic information as our species, and we have a fairly recent common ancestor, but it's the "small" number of genetic mutations that causes the differences. Brains are mouldable by your life experience, but there is a certain amount of your brain that is set in stone, programmed in your DNA before birth, so to speak (there's a good documentary series about the brain on BBC at the moment). There are some species of fish and reptile that are able to go into the wild from their moment of birth, without their parents, and survive. This is because a lot of information is already programmed into their brains.
You get genetics from your parents, NOT from a racial group. All humans share genes, they are not separated into ethnic classes. People have similar skin colours because their parents did and so on and so forth. It comes from a SINGULARITY - a shared ancestor, "racial" similarities are mere coincidence.
