Interesting comments that really cut to the nature of who we are, how we're meant to act and how we live lives that are inconsistent with our genetic upbring. I'm going to stay off of the monogamy aspect as it is too emotion laden (though the interplay of our genetic upbringing combination with societally imposed norms is fascinating). However, it is very sad the extent to which non-sexual touch has a decreasing role in our lives. It seems like a weird mix of puritan morality in combination with commercially driven hypersexuality that causes there to be no friendly/warm touching. Look at a two year old, prior to being polluted by our crass, commercialized, sexualized culture they grab your hand to pull you around, go for hugs, etc.
Also, thanks for posting the question, I greatly enjoy reading about sociologically oriented paleo topics. By virtue of the introspective nature of the individuals on this site, the responses are really interesting.
