This post shows a lack of basic intellect and a commitment to a faith based dogma without regard for reason or science. There is nothing remotely more parsimonious about biological and genetic explanations for complex human behaviors than environmental/learning explanations. That there are some genetic influences on behavior and that there are some environmental/learning influences on behavior are both established empirical facts beyond reasonable doubt. In fact, since no two persons can be in exactly the same place and time at all moments, we know that the environments each person experiences is different from every other person, whereas genes are not always different, such as with identical twins. So, we always know as fact not assumption that there is variation in environment between the people whose behavior varies in any particular way. And with non-identical twins, we know there is also genetic variation between those persons. Genetic science shows expression of even a single gene is a highly complex process, and that most genetic influence on complex human behaviors results from multiple aspects of the genetic code interacting in countless ways with each other the environmental conditions. Thus, by no stretch is any "natural" or genetic explanation for a complex behavior more parsimonious than one involving learning from the environment. The biological explanation for sex differences in violence gets its support from empirical evidence that shows a causal pathway via testosterone along with other evidence, and NOT b/c biological explanations for behaviors have some inherently a priori benefit in terms of parsimony.
