In this episode, we climb up, down and all around our evolutionary family tree. When did we branch off from our more ape-like ancestors? And will we evolve one day into a different species altogether? We'll meet a bearded scientist from 160 years ago (no, not Charles Darwin) and eat some sundaes (thanks lactase persistence!). Plus a brand new Moment of Um answers the question: Do insects have the same blood as humans?
