In terms of human history, how did the idea of "locking someone into a relationship" develop? Dr. Lisle discusses the evolution of relations in the human species eventually getting to why are people  winding up in a relationship that they feel they have to stay in.  There is a brief discussion about the book Sex at Dawn and the argument for polyamory.   We find out that the modern world brings modern dilemnas in dating but we still operate under the same psychology as that of our ancient ancestors.    Copyright Beat Your Genes Podcast Host: Nathan Gershfeld                               Interviewee: Doug Lisle, Ph.D. www.BeatYourGenes.org   Intro & outro song: City of Happy Ones · Ferenc Hegedus
