Evolution’s 180-Million-Year-Old Secret: Scientists Discover Potential Origin of the First “Warm-Blooded” Dinosaurs
21st May 2024
A new study led by researchers from UCL and the University of Vigo suggests that the ability to regulate body temperature, a characteristic shared by all mammals and birds, may have first evolved in some dinosaurs during the early Jurassic period, around 180 million years ago.
In the early 20th century, dinosaurs were considered slow-moving, “cold-blooded” animals like modern-day reptiles, relying on heat from the sun to regulate their temperature. Newer discoveries indicate some dinosaur types were likely capable of generating their own body heat but when this adaptation occurred is unknown.
