Stone Age Software

Your brain was built for a world that no longer exists.

Every week, you'll discover why you feel, fear, and do the things you do — explained through human evolution, psychology, and anthropology, drawn one doodle at a time. From why strangers make your heart race to what ancient humans actually did all day, every video takes something you experience daily and reveals the ancient machinery behind it.

New video every week. Subscribe and meet the stone-age brain you're still carrying around.
