Christopher Ryan of Sex at Dawn has done a short and funny TED presentation:
I highly recommend Sex at Dawn (check out my previous blog post on this) but if you just have a few minutes, this is a fun one. Ryan explores why humans are so preoccupied with sex, what sperm competition means and the significance of the butt bra, among other things. Enjoy!
ps: yes, bit unfortunate to liken monogamy to vegetarianism but hey, we all get to make our own selective jokes! I prefer to liken non-monogamy to a smorgasboard and monogamy to having to eat processed food from the same menu over and over again. There.
