Sebastian is not afraid to admit that he lacks natural rhythm. But Rutendo thinks he’s too hard on himself – perhaps the world is just out of sync with him. Besides, every living thing is built upon natural rhythms, from our response to night and day, to the beating of our hearts.

Kristina Bolinder leads us on an exploration of a plant with a very unusual habit: it only flowers under the light of the full moon. The reason why connects a century of lunar records with the latest in botanical research.

Deep in the Budongo Forest in Uganda, a team of researchers has been following a group of chimps for several years, and learning that they each have their own signature rhythm, expressed through drumming on the base of trees. What’s more, they can choose when to reveal their identities through their drumming, and when to keep them hidden.

Frozen Planet II Producer Rachel Scott tells us about the rhythm of life in the Arctic, from the devastating effects of climate change, to a beautiful and unexpected

sequence featuring polar bears dancing on ice.

We close with the friendly tap-tapping sounds of the Great Spotted Woodpecker – who reveals much within its rhythm.
