The reading explains several different theories about how Agnostids, a group of marine animals that became extinct about 450 milion years ago, may have lived. However, the lecturer casts doubt on the all theories.
First, the author asserts that the agnostids may have been free-swimming predators that hunted smaller animals. Because agnostids were primitive arthropods, and there were other types of primitive arthropods which were strong swimmers and active predators. Also, there were smaller organisms in ancient occean for them to prey on. In contrast, the professor rebuts the idea, for agnostids did have tiny poorly eyes, and they could not track their preys. Also, they did not have any alternative organisms to help them find preys.
Furthermore, the reading mentions another possibility of the way of agnostids living. This possibility is based on some other types of primitive arthropods which they dwelled on the seafloor, and it is possible that the agnostids survived by scavenging dead organisms or by grazing on bacteria. On the contrary, the lecturer refutes this theory with mentioning the fact that agnostids were living in multiple areas, and they were spreading in a large geographic area. Hence, this issue shows that they moved fast, and they had ability to reach far distance; while , seafloor dwellers did not have these abilities, and it is unusual for them to move fast or far.
Finally, the reading passage brings up the idea that the agnostids may have been parasites, living on and feeding off larger organisms. Moreover, there are some modern-day arthropods that exist as parasites. Conversely, the professor contends that parasites typically live in small population while the agnostids had great size of population. In fact, if parasites are too many, their host organism may have been killed; therefore, this fact rules out the last theory too.
