In Why Are We Like This? science journalist Zoe Kean takes us behind the scenes of the evolutionary paradoxes that make up life on this planet. Exploring with scientists, from freezing in Tasmanian sleet to a laboratory of sleeping sharks in North Queensland, we see how these evolutionary mysteries might just uncover the secrets of a better life for humans and the creatures we share the planet with. The ancient ancestors of life on Earth faced the same challenges we do, so let's learn a lesson or two about how they dealt with them.
