Endotherms are animals such as modern birds and mammals that keep their body temperatures constant. For instance, humans are endotherms and maintain an internal temperature of 37°C, no matter whether the environment is warm or cold. Because dinosaurs were reptiles, and modern reptiles are not endotherms, it was long assumed that dinosaurs were not endotherms. However, dinosaurs differ in many ways from modem reptiles, and there is now considerable evidence that dinosaurs were, in fact, endotherms.
Polar dinosaurs
One reason for believing that dinosaurs were endotherms is that dinosaur fossils have been discovered in polar regions. Only animals that can maintain a temperature well above that of the surrounding environment could be active in such cold climates.
Leg position and movement
There is a connection between endothermy and the position and movement of the legs. The physiology of endothermy allows sustained physical activity, such as running. But running is efficient only if an animal's legs are positioned underneath its body, not at the body's side, as they are for crocodiles and many lizards. The legs of all modern endotherms are underneath the body, and so were the legs of dinosaurs. This strongly suggests that dinosaurs were endotherms.
Haversian canals
There is also a connection between endothermy and bone structure. The bones of endotherms usually include structures called Haversian canals. These canals house nerves and blood vessels that allow the living animal to grow quickly, and rapid body growth is in fact a characteristic of endothermy. The presence of Haversian canals in bone is a strong indicator that the animal is an endotherm, and fossilized bones of dinosaurs are usually dense with Haversian canals
The passage stated three evidence that dinosaurs were endotherms. However, the speaker pointed out three explanations opposed the passage.
The author said, because of finding the dinosaurs in a cold region that indicates that dinosaurs were endotherms to survive in such cold climate. On the other hand, the lecturer stated that fossils discovering are not necessarily referring to endotherms identity, but dinosaurs were migrating to warmer places.
Second, the writer stated that dinosaurs had legs under their body like other endotherms animals, which is clear evidence that dinosaurs belong to endotherms. However, the speaker contradicted that by giving an explanation for why dinosuars' legs were under their body, that because of dinosaurs had a huge body with a big size that could be the reason for the under body legs.
Third, based on the writer explanation,dinosaurs had Haversian canals ,which in turn allows the body to grow quickly, and because of the endotherms' characteristic is to grow very fast, that a direct evidence proofs that dinosaurs were endotherms. On the other hand, the speaker pointed out that although dinosaurs had Haversian canals, they did not rapid quickly. Dinosaurs were growing reapidly then slowly which is not related to enotherms animals.
