However, the process of endothermy evolution and its timeline in birds and mammals remains controversial. In a new report on Science Advances, Enrico L. Rezende and a team of researchers at the Center of Applied Ecology and Sustainability, and the Institute of Environmental and Evolutionary Sciences in Chile, combined a heat transfer model with theropod body size data. The researchers then reconstructed the evolution of metabolic rates along the bird stem lineage. The results suggested that a reduction in size constituted the path of least resistance for endothermy to evolve\u2014maximizing thermal niche expansion, while reducing costs of elevated energy requirements.&#013;<br \/>\n&#013;<br \/>\n&#013;<br \/>\n Click here for original story, <a href=\"https:\/\/phys.org\/news\/2020-01-dinosaurs-evolution-endothermy-birds.html\" target=\"_blank\" rel=\"nofollow noopener noreferrer\">Shrinking dinosaurs and the evolution of endothermy in birds<\/a>&#013;<br \/>\n&#013;<br \/>\n&#013;<br \/>\nSource: Phys.org&#013;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The evolution of endothermy (thermoregulation by metabolic means) represents a major transition in vertebrate history.
