Techartlead,

You response is just irrelevant. IQ scores are derived from specific learned behaviors such as knowing how to read and write in a particular learned language. So there have to be environmental factors involved.

Human behavior is extremely complicated and it's just not a straight deterministic connection between behavior and genetics. If what you say is correct would you say that behavioral syndromes such as pedophilia, serial killing, serial raping, necrophilia, toe-sucking, shoe fetishism, behavioral homosexuality, kleptomania, transgendering, etc. all have a genetic base?

And for people like you who believe in the primacy of genes in human behavior, waht specific genes are involved in seemingly non-learned behaviors like tongue-rolling, ear wiggling, eyeball-contortions{scary], extreme body contortions, etc. And how come such interesting(humor here) genes are not selected for and passed on. In other words, who do do you think would select as a preocreational mate someone who is an eyeball-contortionist?
