This is obviously false as evolutionary theory has branched us for a reason, for efficient fulfillment of sexually divergent roles & tasks - changing brain structure is such obvious low hanging fruit for role specialization, dimorphic evolution would mandate differing gene expression.
In order to defend the OA you would have to invent a way to specialize at fulfilling a new biological role environment without using any of the tools available to evolution and just as well as if you did, ie differing regional brain size and connection densities - among thousands of other variables.
"...there are sex/gender differences in brain and behavior... some more common in females compared with males, some more common in males compared with females"
"Our study demonstrates that... there are sex/gender differences in the brain"
"Most brains are comprised of unique mosaics of features, some more common in females compared with males, some more common in males compared with females, and some common in both females and males. Our findings are robust across sample, age, type of MRI, and method of analysis..."
