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.

The reading and lecture are both about whether dinosaurs are endotherms or not. The author feels that they are endotherms and there are reasons that support this idea. However, the lecturer challenges the claims made by the author. She is of the opinion that these explanations are faulty.

Firstly, the reading states that, the endotherms can well afford cooler temperature and so fossils of polar dinosaurs are discovered from the Polar Regions. This argument is refuted by the professor by stating that, polar regions are much warmer than now a days, when cooler climate occurs they tend to migrate or hibernate to other areas. So onlt non-endotherms can do a moving pattern like this.

Secondly, the author posits that, the position of legs was more suitable for the dino's to run. Therefore the endotherms had asustained physical activity which favors the claim of the reader. On the contrary, the lecturer said that the legs position is for bearing the enourmous weight of the animal not that it is endothermic. So that she is proving that dinosaurs are non -endothermic like crocodiles and other reptiles.

Finally, the author tells that, the fossils of the dinosaurs had an extensive harvesian system that is inevitable for the rapid body growth of the animal. Moreover this bone structure is strongly suggestive of endothermy. But the lecturer asserts that the growth ring pattern of the dino bones so extensive and the pattern grew slower in cooler temperature confirms that tgey are non endothermic.

The reading and lecture are both about whether dinosaurs are endotherms or not. The author feels that they are endotherms and there are 3 reasons to support this idea. However, the lecturer challenges the claims made by the author. She is of the opinion that these explanations are faulty.

Firstly, the reading states that the endotherms can well afford cooler temperature and so fossils of polar dinosaurs are discovered from the Arctic Regions. This argument is refuted by the professor by stating that, polar regions are much warmer than nowadays. When the cooler climate occurs, they tend to migrate or hibernate to other areas. So only non-endotherms can do a moving pattern like this.

Secondly, the author posits that the position of legs was more suitable for the dinos to run. Therefore the endotherms had a sustained physical activity that favors the claim of the reader. On the contrary, the lecturer said that the legs position is for bearing the enormous weight of the animal not that it is endothermic. So that she is proving that dinosaurs are not -endothermic like crocodiles and other reptiles.

Finally, the author tells that the fossils of the dinosaurs had an extensive harvesian system that is inevitably showed the rapid body growth of the animal. Moreover, this bone structure is strongly suggestive of endothermy. But the lecturer asserts that the growth ring pattern of the dino bones is so extensive and the pattern grew slower in cooler temperature confirms that they are non-endothermic.
