The egg is right up there with Earth’s greatest creations. Over 99 percent of all animal species that have ever lived on the planet have emerged from some kind of egg, and a few of them have been huge.
Just take the South Island giant moa, for example. A flightless giant that once roamed around New Zealand right up until the first humans arrived around 700 years ago. We were instrumental in its extinction, but there is hope the world could see a moa-like bird again. Thing is, with no animal left alive that’s comparable in size, we’re gonna need a bigger egg.
