Is Evolution Responsible for Girls not farting?

loll loved your ogy and way of synthesizing what would appear to be a logically plausible and intuitive theory..however truth holds that the process of "farting "is a basic requirement,one could not makes such an umption and if we are going back to erectus (the predecessor of -sapiens (us) i think that women in this case lacked the intelligence to visualize the consequences of such actions and when people become more intelligent they evolved logical reasoning and accept this process as a natural one,There is no such thing as farting DNA however their DNA fragments (example metabolic rate of the thyroid gland) etc may have indirect causes,still there is no correlation to support your theory though :P.
