Las aves sobrevivieron a los dinosaurios gracias a sus mayores cerebros

Esta es la conclusión de un estudio del que se hace eco este artículo del Natural History Museum de Londres, del que copio y pego el siguiente extracto:

"Birds today are the direct descendents of the Cretaceous extinction survivors, and they went on to become one of the most successful and diverse groups on the planet", says Natural History Museum palaeontologist (fossil expert), Dr Stig Walsh. "There were other flying animals around, such as pterosaurs and older groups of birds, but we’ve not really known why the ancestors of the birds we see today survived the extinction event and the others did not. It has been a great puzzle for us – until now."
