350 million years ago, eggs could not survive far from water, therefore animals were water-bound. That is, until the amniotic egg, which allowed animals to live a fully terrestrial life. April Tucker peels back each layer of the amniotic egg, revealing how truly extraordinary this evolutionary marvel is.
