Recent studies found that the long lost species of flightless bird Aldabra Atoll which were normally found in the Indian Ocean has returned to its habitat and is returning back to back surprisingly. Which proves that the long gone species of Aldara can return very soon. According to the studies, this species vanished around 136,000 years ago due to the rise in the water level of the Indian Ocean. But when the water level fell down again, the fossils proved that the species re-colonized again but lost its flying abilities.
Dr. Julian Hume, avian paleontologist and research associate at the Natural History Museum, said in a statement, “These unique fossils provide irrefutable evidence that a member of the rail family colonized the atoll, most likely from Madagascar, and became flightless independently on each occasion, Fossil evidence presented here is unique for rails, and epitomizes the ability of these birds to successfully colonize isolated islands and evolve flightlessness on multiple occasions.”
Aldabra has again found its home on its island where it used to be and it is the last one of its species of flightless bird in the Indian Ocean. According to scientists, this is the first time ever that this kind of evolution is discovered again in rails which are the most significant incident ever in terms of birds. In the verge of extinction, where around 1 million species of animals and plants have almost gone missing, Aldabra rails have occurred like hope to the world indeed.
Co-author Professor David Martill, a paleobiologist at the University of Portsmouth, said, “We know of no other example in rails, or of birds in general, that demonstrates this phenomenon so evidently, Only on Aldabra, which has the oldest palaeontological record of any oceanic island within the Indian Ocean region, is fossil evidence available that demonstrates the effects of changing sea levels on extinction and recolonization events.”
