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.

Whether dinosaurs were endotherms is the focus of both the writer and the professor. In the writing, three pieces of evidence, including polar dinosaurs, leg position and movement, and Haversian canals, have been elaborated. The professor, however, claims that many scientists do not think these pieces of evidence are convincing.

An opposed to the writer's idea that the dinosaur fossils were found in the Polar Regions where only endotherms can be alive. The professor states that this evidence can not figure out that dinosaurs were endotherms. He advances the theory by saying that the Polar Regions were warmer at that time, so dinosaurs could live in these places, and when these places became colder, dinosaurs could migrate to other warmer places.

The professor continues to discredit the writing's assertion that dinosaurs' leg positions were underneath the body, which indicated dinosaurs were endotherms, by examining the fact that the leg position can not be evidence for endotherms. In detail, he points out that dinosaurs had legs underneath the body only because they were necessary to develop larger size.

It is the professor's third argument that Haversian canals can not prove that dinosaurs were endotherms, which contradicts the view of the writer that Haversian canals can credit that dinosaurs were endotherms. To explore deeper, the professor contends that the dinosaurs had growth rings that indicated the growth rate, and these growth rings showed that dinosaurs were growing more slowly or even stopped growing when the climate became colder; however, endotherms are growing stably at these extreme climates.

An apparent divide exists between the writer and the professor on whether the dinosaurs were endotherms.
