Reasons why Pterosaurs were not capable of powered flight.

The text and the lecture offer two opposing views on whether Pterosaurs were able to powered flight or not. While the reading passage asserts that they were not capable of power flying, the professor claims that recent researches confirm the possibility of Pterosaurs' powered flight, and refutes each of the reasons author has given.
First, the article posits that powered flight saps a lot of energy from an animal, and because Pterosaurs were cold-blooded, so they had not enough energy to be able to fly as such. On the other hand, the lecturer refutes this by stating that recent discoveries substantiate that Pterosaurs had some kind of hair cover over their skins which means, based of our knowledge of biology, that they were warm-blooded animals. Thus, their metabolism was sufficient to provide them with enough energy required for powered-flight.
Next, the passage claims that Pterosaurs were not able to powered-flight since they were extraordinarily heavy. On the contrary, the professor refutes this assertion by explaining that Pterosaurs were even light compared to their size. According to the professor, new findings have shown that those animals had hollow bones which makes them so light compared to their giraffe-scale height and 12-meter wings that it is reasonable to assume that they could remain in the air flying as long as they wanted.
Finally, the author avers that Pterosaurs were not capable of powered-flight since they had not strong back legs. In contrast, the lecturer rejects the basis of the author's reasoning. The lecturer states that comparing Pterosaurs with birds is not correct because birds in flying depend on their hind limbs while Pterosaurs were relying on all their 4 limbs in flight. She adds that observations of some modern flyers confirm this idea. For example, bats are dependant on their four limbs in flying.
