The reading passage focuses on evidence that is believed to prove dinosaurs were warm-blooded animals. The lecture, on the other hand, offers alternate explanation for each of the arguments.
According to the article, the fact that dinosaurs once lived in Polar Regions suggests that they were endotherms since only warm-blooded animals could be active in such cold climates. In contrast, the professor correctly notes that Polar Regions were actually not as cold as it is today and were once warm enough for cold-blooded animals to survive. When the environment got colder in winter, dinosaurs might have migrated to other locations or hibernated just like how other ectotherms do. Therefore, dinosaur fossils found in Polar Regions can't prove they were endotherms.
Second, the writer claims that the legs of dinosaurs, like the legs of all modern endotherms, were built for sustained physical activity, indicating that dinosaurs belonged to endothermy class. The speaker rebuts this argument when he says such leg position was not necessarily for the purpose of running. He further explains dinosaurs' legs located underneath their bodies could have help support their body weight so they could grow larger, which brought them advantages in survival.
Third, although the professor agrees that there were Haversian canals in the bones of dinosaurs, he doesn't think it is evidence that dinosaurs were warm-blooded. He points out the growth rings discovered in fossilized bones of dinosaurs indicate that they didn’t grow rapidly irrespective of the temperature. In fact, dinosaurs stopped growing or grew more slowly in cooler periods, which is not a characteristic that presents in endotherms, thus it is unlikely that dinosaurs were the same as other birds and mammals.
