The Egg: Life's Perfect Invention

The Egg

The egg is perhaps nature’s most perfect life support system. These remarkable structures nurture new life; protecting it from the outside world while still allowing it to breathe. Eggs 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.

Watch Nature: The Egg: Life's Perfect Invention April 10 at 8:00 p.m. on WCVE/WHTJ/WVPT. Check listings for additional air-times.
