The bird that came back from the dead: Extinction Flilus species comes back to life for second time & # 39;

A flying bird that became extinct when the ocean was flooded by the sea has been brought back to life.

Scientists have said the astonishing resurgence of the bird, a type of rail, has been the result of a rare process called iterative evolution.

It is the first time seen in rails and is one of the most significant in bird records.

Experts found that in two cases, separated by tens of thousands of years, a railroad was able to successfully colonize an isolated atoll called Aldabra in the Indian Ocean.

And at both times, the white-troubled rail – the Indigenous to Madagascar – evolved completely independently into a flying.

The University of Portsmouth and Natural History Museum's research found the last colony survival of the flying rails was still found on the island.

A University of Porsmoth's spokesman said: "This is the first time that ithering evolution – repeated evolution of like or parallel structures of the same ancestors but at different times – is seen in rails and one of the most significant in bird records. . "

He explained that rail types are persistent colonizers that would migrate from Madagascar during frequent population explosions.

One group was colonized by the Aldebra Atoll and because of the lack of predators, like the DoDo of Mauritius, they evolved in a way that they lost their ability to fly.

He explained: "Aldabra disappeared when it was completely covered by the sea during a major inundation event around 136,000 years ago, wiping out all the fauna and flora including the flying rail.

"The researchers studied fossil evidence of 100,000 years ago when the sea levels fell into the ice age, and the atoll was recalculated by flying rails.

"The researchers compared the bones of a fossilized rail from the inundation to bones of a rail after the inundation.

"They found that the wing bone showed an advanced state of flatness and the anxious bones showed outstanding properties that there was evolution to futility.

"This means that one species of Madagascar has risen to two different kinds of flying rail on Aldabra for a few thousand years."

The United States Naturalist Museum of Natural History, Humian Hume, said: "The unique fossils provide irreversible evidence that a member of the railroad family colonized the atoll, most likely from Madagascar, and was fleeing independently on every occasion.

"Fossil certificates here are unique to rails, and they help the birds to successfully colonize isolated islands and evolve their fleetlessness on multiple occasions."

The author of the study was published in the Zoological Journal of the Society of Lions, Professor David Martin – from the School of Earth and Environmental Sciences at the University of Portsmouth, "We do not know any other examples in rails, or Of birds in general, this demonstrably demonstrates this phenomenon.

"Only on Aldabra, which has the oldest political record of any oceanic island within the Indian Ocean area, Fossil Evidence is available that demonstrates the effects of changing sea levels on extinction and recolonization events.

"Conditions were similar to Aldabra, the most important being the absence of terrestrial predators and rival mammals, that a rail is capable of evolving independence independently on every occasion."
