So, they have linked different sexual reproductive strategies to differences in behavior. That cannot be that surprising, right? Different sexual reproductive strategies almost necessitate differences in behavior in general, if the strategies are different enough, which they most certainly are for any kind of mammal or bird. Given the many examples of wildly different behaviors between the sexes in other species - bower birds as an example - any lack of specific behavioral differences would be surprising. It's also no surprising that this sex differences (I don't think these are gender differences; these are the differences that shape gender) are more prevalent in societies with greater economic prosperity; it allows the individuals to follow their own generic preferences, unburdened by economic pressure.
