    Some primates undergo even more extreme childbirth than humans

    Listened

    In progress

    Human childbirth is often difficult and incredibly painful—just ask anyone who’s been through it. And for a long time, childbirth seemed to be uniquely difficult for humans. But a new study suggests that we aren’t alone: Some small primates birth offspring whose heads are nearly twice the size of the mother’s pelvic area.

    So how do those primates go through difficult childbirths? Why didn’t evolution make ours any easier? And what can this tell us about humankind? Flora explores these questions and more with anthropologist Lia Betti.
