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 article introduces the topic of views on dinosaurs were endotherms or not. The writer in the reading passage states three reason to believe that dinosaurs comes under endotherms whereas the lecturer refute this theory and attack each of the claim.
Firstly, writer states that dinosaur's fossil have been found in polar region, which led to one reason that they are active in cold climate and maintained the temperature well. The speaker disagree with this argument and states that polar region was warm enough as compare by today's polar temperature and it could be possible that dinosaurs were migrated or hibernated like reptiles in cold polar regions.Hence , according to leacture fossils discovery in polar region doesn't gurantee dinosaurs to be endotherms.
Also , reading passage points to the leg position of dinosaur which is below it's body and supports the idea that this physical position gives physical activity such as running, which is a strong suggestion that dinosaurs were endotherms. On the other hand, speaker believes that this physical structure had other benefits to dinosaurs such as giving support to big body size. Therefore, speaker suggests that leg position doesn't proves that dinosaurs comes under endotherms.
At last , writers supports his theory by saying that Haversian canals in dinosaur's bone is strong point to believe that it allows dinosaurs to grow quickly that is endotherm's characterstic whereas lecturer believes that dinosaurs have growth rings which thicken their bones and stop growing in cold region. So growing rapidly and then stop and again growing , that doesn't suggests that dinosaurs were endotherms.
As we can see both speaker and writer holds different view on the topic.
