Why do we love who we love? Why do we stay when we know it’s over? And how do some couples stay madly in love? These are just some of the questions Dr Justin Garcia has been exploring in a new book called ‘The Intimate Animal’. Justin is an evolutionary biologist and executive director at the Kinsey Institute for Research in Sex, Gender, and Reproduction. He’s been studying how humans have evolved to love, how that can sometimes be at odds with what we desire - and what that means for monogamy and fidelity. In this episode Justin tells Stephanie about his research into everything from the ways we commit to casual sex throughout human evolution, and how we can apply this knowledge to the modern world of relationships.
