Everything You Never Knew About Sex

We had a fascinating guest on last night from the Field Museum, Robert Martin.  He has written a book called, How We Do It:  The Evolution and Future of Human Reproduction.  Among the questions we asked:

  • Why is it necessary for there to be millions of human sperm for every egg?
  • Penis bones are common in the animal kingdom, including primates.  Why don’t human males have one?
  • Are humans evolutionary programmed to be promiscuous or monogamous?
  • Why do women get morning sickness?
  • Why do men have nipples?

Check out my interview with him and hear his answers.  His book is smart, accessible and fascinating!
