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 reading passage indicates that dinosaure was endotherms and shows three reasons behind this stand. However, the speaker in the lecture casts doubt on the claims made in the article. She strongly dinies and states that those logics are outdated and disproves all of them.
First and formost, the author claims that dinsours fossils have been found in the polar region. If they couldnt control body temperature, they must not have been found in the polar region. The lecturer claims that during that time polar region might be warmer than today. so, they can easily survived there. He adds that during cold temperature, they might migrate to a warmer area. Thus, this hypothesis couldnt be true.
Secondly, the writer claims that lag positions of dinosaurs was different from todays reptiles which helped dinosaurs in physical movement. The lecturer argues that dinosaurs weight was supported through legs. And not all high energy endotherms have leg position like this. hence , this argument lacks coherence.
Thirdly, the author claims that haversian canals found in the dinosaurs body which is the solid proof of endotherms.Due to presence of haversian canals living anmals grow quickly. The lecturer states that in dinosaurs fossils growth rings also have been found. this indicates thickness of bones stops growing or slow during cold time. so , both things couldnt be happened at the same time. hence, it disproves the third logic.
