And so I was like, how am I going to study women's brains?

Well, why don't I scan the dads?

And then as soon as I thought of that, I got really interested because I kind of dug into the research on fatherhood.

And there's so much.

And I got fascinated with that.

Exactly.

So our parenting research, research on the parent-child bond, research on the transition to parenthood, it's completely mother-centric.

So we just don't really understand men's experiences of parenting as well.

And I think there are emerging research programs that are attempting to answer these questions.

And that was one reason I was interested.

excited to write the book.

So in the book, I kept calling it hands-on fatherhood.

And then I was like, I'm talking about mammals.

So should it be like paws on fatherhood?

You know, like tendrils on fatherhood, depending on... So I guess active fatherhood is a good term, right?

So you can sire offspring, but to be involved in their actual rearing, turns out humans are pretty unusual because we do have human fathers who are actually involved in day-to-day care.

And so actually, if you look across all the species, fish, males are primary parents.

Birds, biparental.

Males do a ton of parenting.

Frogs, lots of male parenting.
