Extinct for over 130 thousand years ago species of flightless birds, kaviarov a newly re-discovered at Aldabra Atoll, part of the Seychelles, writes
Scientists explain the phenomenon of iterative evolution – a development of one and the same species from the same ancestor, but at different times.
Approximately 136 thousand years ago, the level of the Indian ocean has increased, and the Aldabra Atoll disappeared under the water. As a result, not able to fly kaviarov the rail (Dryolimnas cuvieri) died as a species. However, after about 36 thousand years the island appeared again above the water, and today the bird disappeared again it inhabits.
Kaviarov shepherd is a family of white birds the size of chicken.
Previously, scientists from Tsinghua University in Beijing established the ground feathered dinosaurs turned into birds. They recreated the model of caudipteryx that lived about 125 million years ago. Experiences with a robot dinosaur showed that when the wings started to clap spontaneously, there is a lifting force. The researchers believe that passive flapping wings could be a precursor to the active michaelnyc movements that have developed wings.
