Life Story BBC1, 9pm
Naturalist David Attenborough documents the universal story that unites humanity with every other animal on the planet – the journey through life, and the goal to continue the bloodline through offspring. This edition focuses on the first hurdle any animal will face, surviving infancy. Cameras follow flightless barnacle goose chicks as they strive to find food, leaping 400ft down a cliff from the ledge where they hatched. Meanwhile, in New Zealand, young fur seals have stumbled across a safe haven in which they can learn how to avoid predators.
