Evolution’s 180-Million-Year-Old Secret: Scientists Discover Potential Origin of the First “Warm-Blooded” Dinosaurs

Newer discoveries suggest some dinosaur types were most likely capable of creating their own body heat but when this adaptation took place is unknown.Research Methods and FindingsThe brand-new study, released in the journal Current Biology, looked at the spread of dinosaurs throughout different environments on Earth throughout the Mesozoic Era (the dinosaur age lasting from 230 to 66 million years ago), drawing on 1,000 fossils, environment designs and the geography of the period, and dinosaurs evolutionary trees.The research study team found that 2 of the 3 main groupings of dinosaurs, theropods (such as T. rex and Velociraptor) and ornithischians (including family members of the plant eaters Stegosaurus and Triceratops), moved to colder climates during the Early Jurassic, recommending they might have developed endothermy (the ability to internally create heat) at this time. It sheds new light on how birds may have inherited a distinct biological characteristic from dinosaur forefathers and the different ways dinosaurs adjusted to complex and long-term ecological modifications.
