In the reading passage, the author asserts three reasons why the Pterosaurs are not capable of powered flight, which was refuted by the professor in the lecture who claims Pterosaurs could be capable of powered flight.
First, the author suggests that the Pterosaurs, might as other ancient reptiles, are cold-blooded, meaning they cannot offer enough energy for powered flight. However, the professor indicates that the Pterosaurs' fossil shows that the Pterosaurs have fur covering which is the main feature of the modern bird. Therefore the Pterosaurs could be warm-blooded. With fur covering and being warm-blooded. The Pterosaurs could produce enough energy for powered flight.
Second, the author mentions that the Pterosaurs is too heavy to fly. In contrast, the professor points out that there is plenty of characteristic of Pterosaurs' body making it light enough to fly, like the hollow bones.
Finally, the author insists that the Pterosaurs' back leg are too weak to run fast enough to take off as the modern bird. Nevertheless, the professor refutes that there is the difference between the modern birds and the Pterosaurs. The modern birds use two legs to take off while the Pterosaurs use all four limbs. According to the recent research, even the most largest Pterosaurs could use their four limbs to run as fast as the modern birds. Therefore, Pterosaurs are capable of powered flight as the modern birds do.
