In the lecture, the professor makes a statement thatdinosaurs are not endotherms, casting doubt on the main idea of the readingpassage that the dinosaurs are endotherms.

Firstly, the speaker believes that the fossil of the polardinosaurs is not the enough evidence to support dinosaurs are endotherms. Inaccording to the speaker, the temperature of the polar in the past was warmerthan today, and the fossil is just partial, if the temperature became lower,dinosaurs could migrate or hibernate. While the reading passage clams thestandpoint that dinosaurs' fossils in the Polar Regions showed that dinosaurswere endotherms, in order to adapt the environment of the cold climates,dinosaurs had to keep a temperature well.

In the second place, the lecture states that the legs ofdinosaurs are underneath their body, which cannot explain dinosaurs areendotherms. The dinosaurs have that kind of structure because the legs are usedto support their weigh and they can grow big enough not because to run. On theother hand, the writer thinks that the physiological property of the dinosaurssuggests that dinosaurs are the endotherms.

Finally, the lecturer shows the viewpoint that the growthrinswhich is also in the dinosaurs' bone and this is a clue that dinosaurs grow indifferent speed when they are in the different period. When the climate iscold, dinosaurs stop growing or slow down the speed of growth, and if it becomeswarm, they are in rapid growth. On the contrary, the author states thatHaversian canals allow the alive animal to grow rapidly, and it is a characteristicof endotherms, so dinosaurs are endotherms.

To sum up, the professor illustrates her disagreement withthe general idea of the article by demonstrating the evidences motioned above.
