Essay topics:

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 modern 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.

Boh reading passage and lecture discuss whether dinosaurs are endotherms or not. The former argues that the three pieces of evidence supports that it is endotherms like humans, but the latter contradicts each of these three points.

First of all, the author of the passage claims that dinosaurs are endotherms as it's fossils records are found in Polar Regions and endotherms species can able to maintain its body temperature in that cold region. However, the lecture contends that dinosaurs were preferred to live in the warmer places, and its fossils suggested that this place was hot as the present climate. It migrated to other areas when this region turned into cold as like other reptiles.

Secondly, the text asserts that the leg position of the dinosaurs like it is underneath the body and is the same as endotherm species, and it helps the species to run rapidly. In contrast, the listening counters that the dinosaurs' legs were under the body due to support it's overweight. Dinosaurs were large animals, and their legs were not for running purposes.

In third, the reading article states that the bone structure of dinosaurs proves that it contains thick Haversian canals, and this allows endotherm species to grow faster. On the other hand, the lecture mentions that thick growth rings of the bone allowed dinosaurs to grow in hot temperatures. In the cold climate, the growth of dinosaurs retards. Therefore, it is clear that it is not like endotherms as it can grow in both warmer and cold weather because of its ability to maintain internal constant body temperature.
