Over your lifetime you undergo an extraordinary change - no other animal on earth goes through such a dramatic metamorphosis.

They uncover the reason our childhood is longer than any other creature on Earth and reveal the communities of microbes - our microbiome - that we cultivate throughout our lives. They uncover the mysterious trigger for our transformation from child to adult and, for the first time, show the remarkable spark of life that is emitted when sperm and egg first meet.

S1 E2 • Survive

In this programme Chris and Xand van Tulleken discover the everyday miracles that keep you alive. They explore the extraordinary lengths our bodies go through to keep our bodies and organs working every second, of every hour, of every day - through the process of homeostasis. From surviving Nordic ice swimming, to seeing how powerful reflexes of fear and disgust keep us safe from danger, and uncover the amazing mechanisms our bodies call on to repair damage. And for the first time ever they see exactly how our immune system's killer cells go into battle against deadly infection.

S1 E3 • Learn

This programme explores the way our experiences shape our minds and bodies as we make the journey from the most helpless to the most sophisticated organism on earth. Dr Chris and Dr Xand van Tullekan uncover how we develop new skills - whether riding a bike or learning to walk. They reveal the unexpected link between our heartbeat and our ability to talk. And they show, for the very first time, how memories are formed in our brains, and how our experiences continue to change our bodies and even our genes themselves throughout our lives.
