‘Tree of life’ links birds to 3 dinosaur lineages

Rick Prum, the senior author of the study and a professor of ornithology, ecology and evolutionary biology, said that this signifies the possible end of avian evolutionary theories.

Humming birds reply heavily on vision and arose from nocturnal ancestors.

Now understanding the family tree among the birds will not be hard as years of research has allowed scientists to derive and rearrange the species to present a comprehensive bird family tree.

Birds evolved from small featured dinosaurs. Among these, Archaeopteryx was estimated to be the one of the first to have evolved, about 150 million years ago. The early ancestors of thousands of these species appeared to have evolved suddenly within a few million years after the extinction the non-avian dinosaurs. Yale avian paleontologist Daniel Area stated the analysis indicated the newest frequent ancestor of all fashionable birds most likely lived about seventy five million years in the past. The three lineages of bird, which survived at that time, were responsible for the evolution of all the modern birds. “Any attempt to understand their biology at a broad scale requires an understanding of this deep historical context”, Berv said. Despite these huge findings, the evolutionary history of 90 percent of contemporary birds in the Neoaves group has remained a mystery.

The brand new research, printed within the journal Nature, additionally reveals fascinating relationships amongst dwelling birds throughout the group.

Through the study, it was found that the majority of the water birds have close associations, implicating that they came out to the world in aquatic places after the end of the dinosaurs. For instance, other than the ducks and the cranes, most of the world’s water birds are closely related – suggesting they radiated out across the globe in aquatic niches following the extinction of dinosaurs and did not, as previously thought, evolve from multiple independent lineages. Richard Prum, Yale University ornithologist, said that since the new family tree confirms the existence of hummingbirds and swifts, it raises question on how these birds are able to see so well.

Prum said the experts can begin to analyze the patterns and processes that resulted in the spectacular differences of living birds once the family tree has been completed.
