Episode 2: Your Inner Reptile
Neil travels back over 200 million years to a time when our ancestors were reptiles with features that we have inherited today.
Neil reveals how our reptilian past has left its mark on the structure of our skin, the shape of our teeth, and even our ears. The journey takes him from his dentist in Chicago, to the Karoo desert in South Africa, where he uncovers a key moment in our evolutionary past – the transition from reptile to mammal.
