NATURE: The Egg: Life's Perfect Invention The egg is perhaps nature's most perfect life support system. These remarkable structures nurture new life; protecting it from the outside world at the same time as allowing it to breathe. They are strong enough to withstand the full weight of an incubating parent and weak enough for a hatchling to break free. But how is an egg made? Why are they the shape they are? And perhaps most importantly, why lay an egg at all? Step by step as the egg hatches, host David Attenborough reveals the wonder behind these incredible miracles of nature.

VIDEO USAGE RIGHTS

Why the AV version? Because it provides additional usage options for PBS videos. AV versions come with limited performance rights so they can be shown in classrooms, at PTA meetings, during after school programs, and transmitted on a closed-circuit system within a building or on a single campus. They also can be enjoyed in admission-free public screenings, which also makes them ideal for use by library patrons and businesses involved in community clubs and organizations.
