The passage and the lecture debate on whether pterosaus were capable of powered flight. The passage points out that pterosaurs were cold-blooded and thus unable to produce enough energy for flight, too heavy to flight and could not take off from the ground. Finding these claims arguable, the lecture casts doubt on these and count them weak.
To begin with, according to the passage, it is said that large pterosaus were cold-blooded animals so that they were not able to provide enough energy for flight. The lecture, though, dismisses it by saying that the fossils of the pterosaurs show that they were coverd with fur. In this case, they were like warm-blooded animals that could generate enough energy to maintain metobolism when temperature was low. As a consequence, they could produce energy for flight.
What is more, the passage contends that pterosaurs were so large that they could not flap their wings fast enough to stay aloft. By constrast, the lecture disputes that because they actually were light. Although they were large, their bones were hollow rather than solid, contributing to the low weight. Under this curcumstance, the pterosaurs could fly.
Finally, the passage is favor of the idea that the back legs of pterosaurs were too small and weak to allow them run fast enough or jump high enough to launch into the air, which is contradicted by the lecture. The lecture holds the opinion that the birds is not a good example to illustrate. Birds had two legs on the ground, nevertheless, pterosaurs had four legs on the ground, just like those of bats. Bats could push themselves off and launch themselves into the air using four legs. Assembly, pterosaurs could also do that. By and large, large pterosaurs were capable of powered flight.
