The reading article talks about three arguments to dismiss that Pterosaurs were capable of powered flight, which flying by flapping wings. The lecture refutes the claims presented in the reading article using supporting evidence.
First, the reading argues that, ancient reptiles were cold blooded like modern reptiles and had slow metabolism. Due to this, they were unlikely to produce enough energy required for powered flight. The lecture counters this claim and points out that, the fossils discovered show the presence of dense hair covering like fur on Pterosaurs. Warm blooded animals usually have fur to maintain body temperature, which indicates Pterosaurs were warm blooded and increases the chances of capabilities of powered flight.
Next, the reading presents an argument that, there is a weight limit to take powered flight and to stay airborne. Pterosaurs were large animals like Giraffe and were too heavy to fly and to flap wings fast to stay afloat.
However, the lecture dismisses the argument and states that, it is now known that modifications in anatomical features made Pterosaurs light. It had hollow bones that reduced the body weight and made flapping and staying afloat easier.
Lastly, the reading passage states that, for Ptersaurs lack large powerful leg muscles to take off from the ground for powered flight. The lecture refuses the claim and states that, birds use hind limbs to walk on the ground and for take-off. However, Pterosaurs used four limbs to push off from the ground. Moreover, the professor adds that, a study revealed that Pterosaurs used all four limbs to walk and for take-off to fly in the air.
In conclusion, the lecture counters the all three claims presented in the reading and states that research showed that Pterosaurs were capable to fly.
