They obviously do and just about any question in biology is going to be answered with "because it was evolutionary advantageous we'll come up with story how that advantage developed later".

Of course. What women are attracted to and their willingness to mate changes during their monthly cycle. Furthermore there's a peak in births during September. Sure there are psychological and sociological causes for preferring to mate in December but psychology and sociology are not separate from biology. I don't understand why you're pretending that his isn't common knowledge.

Menstrual cycles are not estrous cycles.
