The reading considers that dinosaurs are endotherms, while the lecturer opposes the point by providing contradict evidences.
The reading says the polar dinosaurs must be endotherms because they have to adapt to the surrounding cold weather. However, the speaker argues that the weather billions of years ago were warmer than that of today, so the animals could be capable of enduring it during warm monthes. Additionally, during cold months, the dinosaurs can move to warmer places or herbinate. Therefore, the evidence in the reading is unconvicing.
It is stated in the reading that dinosaurs’ leg position differs from that of reptiles, which can support that dinosaurs must be endotherms. But according to the speaker, the dinosaurs’ legs are under their body because the legs can hold their large body in order to grow to a big size. Thus their legs’ position is just because of their adjustment to live and have nothing with movement, which can opposes reason mentioned in the reading.
The speaker also says that although the dinosaurs have haversian canals, the fact cannot be the evidence of they being endotherms. Because dinosaurs have a kind of ring in bone to limit the growth of dinosaurs during cold months. Thus the dinosaurs don’t grow quickly all the time, but grow in a cycle of slow, normal and rapid speed, which is totally not a character of endotherms.
