Welcome to Amy Alkon's HumanLab: The Science Between Us, a weekly show with the luminaries of behavioral science.

On this show, anthropologist Dr. Kermyt Anderson will lay out what the research says about fathers, stepfathers, grandparents, and how children are transformed by and transform the men who care for them. 

Dr. Anderson’s book we’ll be discussing tonight is Fatherhood: Evolution and Human Paternal Behavior. It was co-authored with fellow anthropologist Peter B. Gray. Also check out Anderson and Gray’s blog at Psychology Today, “The Evolving Father.” 

Join me and all my fascinating guests every Sun from 7-7:30 pm PT and 10-10:30 pm ET, here at blogtalkradio.com/amyalkon or subscribe on iTunes or Stitcher.

And please support the show by buying my science-based, funny book, "Unf*ckology: A Field Guide to Living with Guts and Confidence."
