▶ Your Answer :
In the reading passage, there are three possible theories that how agnostics may have lived. But the lecturer contradicts the statement one by one and claims that the three theories are unreasonable.
First, the writer suggests that the agnostids were free-swimming animal and they ate smaller fishes. They were the primitive arthropods and the arthropods were normally swimming predators. Plus, there were many smaller preys to eat in the ocean. In the lecture, the claim is not true because of the physical characteristic. Predators have large and well-developed eyes to seek their preys. However, the agnostids have tiny eyes and it seems like they were almost blinds. According to the fossil records, there are is no evidence that they were able to chase their preys.
Next, the reading claims that the agnostics may have lived on the seafloor because many types of arthropods had that kind of lifestyle. They may have eaten dead organisms or bacteria in the deep sea. But, the professor disagrees with the theory because they had an ability to move far and fast. Typically, the seafloor animals are only living in small areas. The fossils of the agnostics have been founded in multiple geography areas. It means they were able to swim fast and far from one site to another site.
Last, the reading passage asserts that they could have been parasites. The agnostids were arthropods and many species of anthropods are living as parasites these days. In the lecture, the possibility of that the agnostids were parasites is a weakness. Normally, parasites species are not large population because they have a limited host. But the agnostids were a number of population and it proves that they were not living as parasites. |
