Animals with higher body temperatures are more likely to evolve into herbivores, study finds

A University of Arizona study has uncovered a surprising relationship between an animal's body temperature and its likelihood of evolving into an herbivore. The study, published in the journal Global Ecology and Biogeography, offers fresh insights into the evolution of plant-based diets across tetrapods, which include the land vertebrates—amphibians, birds, reptiles and mammals. The findings could reshape scientists' understanding of the evolution of animal diets.
