I just re-read your post. Excellent.
Biochemistry and pheromones etc play a huge part in partner selection.. It is all based on immune system compatibilities and genetic
imperfections. You do not want a mate whose immune sysytem is identical to yours = you'd want to combine two different
immune systems, threrefore affording your offspring a stronger chance of survival, same with genetic imperfections.
You know how certain people just don't smell good to you ? It's not that they are unclean, it is just that their body's natural
odor/aroma is not pleasing to you. That's your senses/pheromones doing the pre-selection of a potential mate..
A good, simple summary you put up, interesting to read it from a philosopher's point of view
