Genes don't determine our brains (or our bodies), but they do constrain them. The developmental possibilities for an individual are neither infinitely malleable nor solely in the hands of the environment. But the insight that thinking, behavior, and experiences change the brain, directly, or through changes in genetic activity, seems to strip the word "hardwiring" of much useful meaning.
