David Attenborough examines animals with extreme young. The panda gives birth to the smallest baby of any mammal, while the kiwi's egg is almost too large to lay.

The giant panda gives birth to the smallest baby of any mammal and has to care for and protect it for many months. Why don't they give birth to more developed, robust young? The kiwi lays one of the largest eggs in the bird world, which produces a very well-developed chick. Why do kiwis produce a single egg that is a quarter of its body mass and almost too big to lay?
