New Study Challenges Theory on Tuna Evolution and Dinosaur Extinction

Tuna’s speed and warm blood evolved over 50M years, not from dinosaur asteroid

A long-standing scientific theory linking the extinction of dinosaurs to the evolution of modern tuna has been challenged by a new Yale University study. Researchers have found that the asteroid strike that wiped out non-avian dinosaurs 66 million years ago did not directly trigger the evolution of large, fast-swimming, warm-blooded predators such as tuna.
