The reading and the lecture both are about Pterosaurs. The professor in the talk mentions that Pterosaurs were capable of powered flight. However, the article casts doubt on the claims made by the professor. The reading suggests that heavy Pterosaurs were not able to power flight and provides three explanations.
To begin with, the professor in the talk asserts that recent studies from fossils of Pterosaurs reveal that Pterosaurs have a dense thick hair-like covering, which is fur-like and this indicates that they are warm-blooded. In addition, he mentions that when the temperature outside is cold they increase their body temperature. If the metabolism is same as warm-blooded then it is evident that Pterosaurs have the energy for Powered-flight. The reading, on contrary, refutes the point made by the professor, the article states that modern-reptiles are cold blooded like their ancestors, and thus they have low-energy and metabolism and cannot power flight.
Moreover, The lecturer contends that though the pterosaurs have a huge and heavy body. Their bone is light and hollow, which makes them lightweight and thus they are able to fly. The article challenges the point made by the lecturer. According to the article, the pterosaurs are heavyweight reptiles, which cannot fly in the air.
Lastly, the professor posits that the pterosaurs use all the four-limbs to push themselves from the ground like the bat and it enables the pterosaurs to powered-flight. This point is contradicted by the article. It affirms that large reptiles need big powerful muscles in their back to launch themselves from the ground to fly, which pterosaurs don't have. Thus, this reptile cannot jump high in the air.
