The egg, Iife's perfect invention, nurtures and protects new Iife from the outside world. These remarkabIe structures are strong enough to withstand the fuIl weight of an incubating parent and weak enough to aIIow a chick to break free. But how is an egg made and what is its purpose? From creation to hatching, join host David Attenborough as he reveals the wonder behind these miracles of nature. |
