Stephen, There are absolutely thousands of well-documented studies revealing the impact of gene-environment interactions. What about the behavior of children raised in deprived environments, like low-interactive orphanages? Whatever predispositions they were born with are almost totally extinguished during their early years--as per example, energy levels, verbal abilities, extroversion, etc. This somewhat follows the logic of the statement by Chris that "a gene with no environment is a dead gene."
