An enormous asteroid crashed into the Earth about 65 million years ago. While terrestrial dinosaurs like the famed Tyrannosaurus rex were wiped out, many avian animals really began to flourish. Considering that there are more than 10,000 species of birds on Earth, flourish may even be an understatement. Keeping birds organized in a neat family tree is a bit of a Herculean task, since there are so many species and their evolution has been a little unclear.
Edward Braun The team also found evidence that this spot on the bird chromosome has suppressed the recombination process since around the time the dinosaurs disappeared. It is not clear if the Cretaceous-tertiary Extinction that wiped out the dinosaurs and these genomic anomalies are related.
Jon Fjeldså and Josefin Stiller. “We found that our method of adding tens of thousands of genes to our analysis was actually necessary to resolve evolutionary relationships between bird species,” study co-author and University of California, San Diego computer engineer Siavash Mirarab said in a statement. “You really need all that genomic data to recover what happened in this certain period of time 65-67 million years ago with high confidence.
