I’m not sure I understand the question yet.
What gap?
It’s unlikely that I can’t explain any and all behavior.
It’s likely that like a small number of other human differences, that there is no solution other than political choice. (though that will take explaining). For example, marriage is of questionable post-agrarian value. Abortion is a killing but its it murder. Homosexuality is a developmental defect not a baiting into hazard, but does public tolerance or acceptance impeded family formation? There are a number of these questions.
