A "stronger biologically motivated interest" is different than your original stance of "nature of monogamy." I still don't agree, but it is different.

As I said before, there is no conclusive evidence regarding nurture but social scientists do not dismiss it altogether. It's simply the case that we have never studied the nature of humans and most animals before the social learning process began.

The problem comes with positing a nature argument for female monogamy and not for male monogamy. This is all very tautological and is working backwards to try to biologically explain gender norms.
