In the passage, it mainly talks about some theories about how agnostids behave. The writer illustrates that the agnostids are free-swimming predators, seafloor dwellers, and maybe they were parasites. But the speakers reckons that these theories all have serious weakness, and develops her perspectives in the lecture.
First of all, the author proposes that the agnostids may once been free-swimming because other arthropods were good at swimming and they are predators, hence, we can say agnostids preys in the sea as well. However, the lecturer pointed our that in order to hunt in the sea. the predators has to have large, well-developed eyes, they will need a great vision to capture the prey. But the agnostids only have tiny, poor eyes, while other arthropods have strong vision, agnostids are almost blind. Therefore, agnostids can not be predators, unless they develop some special sensory to help themsevles, which they do not have according to the fossils.
Second, the passage says that the agnostids might lived on the seafloor, because other arthropods living like that, and they can make a living by scaverning dead organisms or by grazing on bacteria. But, the speaker rebuts that the seafloor dwellers usually can not move very fast, so they will stay in local area instead of spreading to a new place. However, many anostids live in multiple geometry areas, this means they can move fast, and across long distance, which makes them very much unlikely to be seafloor dweller.
Third, the author demonstrates that the agnostids are possible were parasites. The women in the lecture retorts this theory by showing that the polulation of parasites normally will not be very large, because if their numbers are large, they will jeopardize the life of their host. But the populations of many agnostids, on the other side, are actually quite large, so this thoery also be ruled out.
So the writer's three thoeries are all proved unconvincing.
