The article and the lecture are both about theories of dinosaur extinction. Whereas the author of the reading states three theories which explains the dinosaur extinction. The lecturer casts doubt on the main points made in the reading by providing three reasons.
According to the reading, asteroid theory explains the extinction. The article mentions that the presence of iridium in earth surface is due to collision with meteorites which has large quantities of iridium. This specific argument is challenged by the lecturer. He claims that earth core is rich in iridium. Additionally, he points out that earth core magma contains iridium which is leaked due to volcanic eruption.
Secondly, the author suggests other theory about extinction of dinosaur which is known as ice age theory. The article notes that glacial period affected dinosaurs. He also states that dinosaurs does not have thermoregulatory systems to survive in extreme weather conditions. The lecturer rebuts this argument. He suggests that there is no evidence of glacial and ice age periods at the time of dinosaurs. She elaborates on this by mentioning that there is evidence of tropical species and the sea levels are high which results in melting of ice caps.
Finally, the author posits that bird evolution theory is another reason for dinosaur extinction. He contends that dinosaurs may be evolved as modern birds. The lecturer, on the other hand, posits that birds have different abilities when compared with dinosaurs. He puts forth the idea that dinosaurs have limited moving abilities. Consequently, there is no logical explanation of evolution of modern birds from dinosaurs.
