A new family tree of birds evolutionarily distances pigeons from flamingos. About 66 million years ago, the impact of a huge asteroid caused the extinction of the dinosaurs and many other animal and plant species on Earth.

After that catastrophic event, the birds that had survived, and that can technically be considered relatives of the dinosaur, emerged and expanded throughout the world. The most detailed census reveals that there are 50,000 million birds around the world This updated family tree reveals patterns in the evolutionary history of birds after that catastrophic mass extinction and corrects relationships that had been wrongly established.
