The reading and the lecture are both about agnostids, which are the ancestors of anthropods and modern insects. While the author of the reading passage proposes three different hypotheses regarding how agnostids might have lived, the professor claims that all these theories have weaknesses. She casts doubt on the main points made in the reading by providing three controversial reasons.
In the reading, the writer begins by saying that agnostids may have been free-swimming predators and haunt tiny animals in the sea. However, the professor disagrees with this idea. She states that most marine animals have large eyes because they need to chase their prey in the sea. Evidence shows that agnostids had poorly developed eyes, and in some cases, they were blind. Also, there is no evidence of any other tracking organs in their fossils to confirm that they had the ability to track their prey.
Furthermore, according to the text, agnostids may have been seafloor dwellers, just like some other types of primitive arthropods. On the other hand, the professor asserts that almost all seafloor dwellers move slowly. Therefore, they usually occupy a limited area of the sea in the proximity of their habitat. Nevertheless, evidence has shown that agnostids spread in a large area of the sea, so they had the ability to move fast. Consequently, they could not have been seafloor dwellers.
Finally, the writer believes that agnostids may have been parasites living on larger animals. Not surprisingly, the professor refutes this assertion by contending that parasites usually do not have large populations because they would kill the host, but agnostids had large populations. This evidence rules out the possibility that they were parasites.
To sum up, both the author and the lecturer hold conflicting views on how agnostids were living.
