Why do some animals have weird genitalia? Why is there conflict between males and females when it comes to producing offspring? Tune into this podcast to hear Art and Marty talk with Patty Brennan about how sex in the animal kingdom is not always about love and cooperation; often it's also about conflict. And, this conflict can lead to some pretty crazy genitalia. Patty is an evolutionary biologist at Mount Holyoke College. Her research shows that the birds and the bees aren't so simple for the birds (or, as it turns out, for most other animals). Follow Patty on Twitter: @sexinnature
