Around 136,000 years ago, a flightless bird became extinct.

The bird resided on the Indian Ocean atoll of Aldabra, which had its flora and fauna wiped out when the island was completely flooded by the sea. 

Now, scientists from the University of Portsmouth and Natural History Museum say the bird managed to return from the dead. 

It's thanks to a rare event called iterative evolution, in which the process of evolution from a same ancestor is repeated along different points in history.
