Although dinosaurs are considered as the strongest creatures that have ever lived on Earth, they were not strong enough to defy extinction. Since there are no definite data that could identify the cause of extinction, many theories have been suggested. These three theories are the most convincing ones.
The first hypothesis is the asteroid theory. This theory gained support from the discovery of an element called "Iridium," which was extracted from a layer of rock. Iridium is a rare element on Earth. In contrast, it is commonly found in meteorites. This led scientists to claim that iridium was scattered widely when a giant asteroid hit the Earth during the time dinosaurs were alive.
The second hypothesis is the ice age theory. It is well known that the glacial period comes every 20,000~40,000 years on Earth. Supporters of this theory say that the glacial period adversely affected nature and influenced the lives of dinosaurs. As many dinosaurs were not equipped with strong thermoregulatory systems, they were vulnerable to extreme weather conditions.
The third hypothesis is the bird evolution theory. Some people argue that dinosaurs evolved into modern birds that we are now familiar with. When researchers compared the body structures of contemporary birds to those of dinosaurs, their characteristics showed striking similarities. Many anatomical features of modern birds, including their skeletons, hearts, and lungs, show high complexity similar to those of dinosaurs.
Recently, there has been a ton of debate as to the causes of extinction of dinosaurs. More specifically, in regardes to the passage, the writer puts forth the idea that there are three convincing causes for the extinction of dinosaurs. However, the lecturer is quick to poin out that there are some serious flaws in the writer's claims. In facts, the professor believes that these three causes is not correct for difining the cause of extinction, and addresses, in details, the trouble with each point made in the reading text.
To begin with, the author states that by the astroid hitting on the earth is one of the causes and he says taht Iridium comes to the earth through astroids and it destroyed the dinosaurs. Some professional in the same field stands in firm opposition to this claims. In the listening, however, the professor calaims that Iridium found in the core in the earth. He goes on to say that by volcanic activity the iridium came to the surface and destroy the dinosaurs.
Secondly, one group of scholar represented by the writer thinks that due to high coldness and ice age dinosaurs were extinct. Of course, though, not all experts in the same sector believes this is accurate. Again, the lecturer specifically addresses this point when he says that at that time the earth were hot . Additionally he notes that due to the hotness of the earth the ice in the polar region is malted and the extinction of dinosaurs were occured.
Finally, the author wraps his argument by positing that dinosaurs were evoluted to birds as there are many structural similarities between dinosaurs and birds. Not surprisingly, the lecture takes issues with this claim by contending that there are no similarity in the movement activities of birds and dinosaurs.
To sum up, both the writer anf speaker hold conflicting view about the causes of extinction of dinosaurs. It is clear taht they will have trouble in finding common grounds on this issue.
