At the time of 130 million years ago., some primitive species of birds live and adapt to the four wings on her body. This is the result of recent research team palentolog from China.
Theses findings revealed by the result of analysis carried out the research team of 11 specimens of primitive wingless birds, four were found in Liaoning province, Northeast China region.
In the report the study results published in the journal Science, a team of researchers led by zheng Xiaoting of the Shandong Tianyu Museum of Nature says that the bird originally had four wings before "scarping" plumage in the lower limbs.
According to the researchers, this species on an evolutionary transition "may have an important role in the procces of the evolution of flight ". The wings on the upper limb is maintained because it could support more efficient flying activity.
The researchers suspected, then the birds ancestors seems to replace their rear limbs feather on the scales and developing legs that resemble the feet of modren bird. Birds are also preparing to use the limb back to begerak like a bird on the ground, robin.
Fossils of primitive birds that were found this time includes several groups of sapeornis yanornis, and confuciusornis. Estimation by Xu Xing, a member of the team from the Institute of Vertebrate Paleontology and Paleoanthropology in Beijing, the fossils are estimated to live in the early cretaceous period.
This latest invention indeed confirm the presence of four winged Bird on bird kinship lines. How ever, the fuction of aerodynamic configuration of these species is still in debate.
Zheng argued that the wings on the lower limbs is owned by ancestors of these birds certainly has fuctions. "(The support) fuctions, such as lifting body aerodynamics of birds, and speed up or enhance the ability of the birds were flying manufer, " wrote Zheng in his report as quoted by the New York Times.
The research of Zheng and his team attracted the attention of another paleontologist, Mark a. Norell Paleontog dinosaurs at the American Museum of Natural History in New York said, the number of graves of cretaceous fossils, China has opened a dinosaurs existence view hairy and evolution of birds.
