Big, flightless birds like the ostrich, the emu and the rhea are scattered around the Southern Hemisphere because their ancestors once flew around the world, a new study suggests.

With no threat of being eaten up by predators on the ground, birds found it easy to go foraging for food – seeds and worms – on the ground. They had nothing to fear, so there was no need to fly.

This means that a single species, the white-throated rail, evolved to be flightless twice — a phenomenon known as "iterative evolution," according to a statement from the University of Portsmouth.
