London, Jan 20 (ANI): Birds survived the catastrophe that wiped off dinosaurs from the face of earth because of their well-developed brains, claims a new study of fossils.
Dinosaurs and early birds such as Archaeopterix, were killed because of a mass extinction, which is believed to be caused by a meteor 65 million years ago.
However, modern-style birds, which had bigger brains, survived extinction from the big calamity.
"Life must have been challenging," Times Online quoted Stig Marsh, of the Natural History Museum, as saying.
He added: The flexible behaviour of the large-brained individuals would have allowed them to think their way around the problem."(ANI)
