Agnostids were a group of marine animals that became extinct about 450 million years ago Agnostid fossils can be found in rocks in many areas around the world From the fossil remains we know that agnostids were primitive arthropods relatives of modern

According to the reading passage, it is stated that since the determination of Agnostids' living conditions and behavior through the fossil remains is not possible, paleontologists have proposed different theories about it. The article presents several theories in this regard. However, the lecturer challenges the assumptions made by the author, and refutes them by presenting three key reasons.
Firstly, the reading contends that just like the primitive arthropods, Agnostids were strong swimmers and preyed on smaller animals. The professor, however, raises skepticism about this assertion by explaining that while animals that are swimming predators have large developed eyes and a good vision, Agnostids have tiny poorly developed eyes or are mostly blind. She emphasizes that Agnostids may have a special sensory organ to catch their prey.
Secondly, the article asserts that Agnostids were living on the seafloor and they survived by scavenging and grazing on bacteria. On the contrary, the lecturer counters this idea by pointing out that seafloor dwellers lack the ability to go around swiftly, and they mostly occupy a small geographic area. According to her, because Agnostids were inhabited in multiple and distant geographic areas, they are not likely to be seafloor settlers.
Finally, the reading posits that another theory for Agnostids is that they were parasites that were living on and feeding of larger organisms. The professor disputes this claim by elaborating that parasite populations cannot be very large, and if they do not be within a certain limit, they will kill off their host. She states that unlike what is mentioned in the passage, Agnostids rule out of this theory as vast amounts of their fossils have been discovered in a single area.
