Humans are unusual dads. Across the animal kingdom, dads are often absent from child-rearing altogether. But among humans, fatherhood takes many forms, and in the last half century, it has changed dramatically. College-educated American fathers now spend nearly four times as much time caring for their children as they did in the 1960s.

And according to new research, this new type of fatherhood doesn't just change a man's schedule or priorities—it can literally change his brain.

Today, Derek talks with USC psychologist Darby Saxbe, author of 'Dad Brain,' about the science of modern fatherhood. They discuss how active parenting affects men's psychology and how changing expectations around fatherhood are reshaping families and men themselves.
