How agnostids may have lived
There is a long-running debate about how agnostids, a kind of ancient marine animals, have lived in the sea. The passage mentions that servel hypothesis have been proposed to answer the question, including free-swimming predators, seafloor dwellers, and parasites. However, the lecture considers them unconvincing.
The passage begins by arguing that agnostids may have been free-swimming predators which hunted smaller animals, since there are other similar primitive arthropods which were also good at swimming and predation. Nevertheless, the lecture counters this, pointing out that preying under the sea require specific ability on eyes or other sensor organisms, which helps perdators to precisely locate their perys. However, agnostids did not show any evidence about unique sensor ability on their fossils. Therefore, the assertion of the passage does not sound reasoning.
Furthermore, the passage assumes that agnostids may dwelled on the seafloor, just like other types of primitive arthropods. The lecture, however, suggests this may not be merited by the evidence. Living on the seafloor limits the movement of animals. Therefore, these animals were only able to move in such a slow mode that they could not occupy areas which seperate far away. However, analysis on the behavior of agnostids suggests they had occupied many areas that are scatted in different locations, thus they must swimming fast enough to move among these areas. The passage cannot bolster the recommendation without ruling out the refutation.
Last but not the least important, even if the evidence turns out to support the passage that agnostids were possible parasites, one critical fact was left out of consideration. The lecture points out the passage neglects the truth that the number of agnostids are in such a high level that they cannot be parasites on any type of other animals, since they may quickly deplete the nutruion of their host, and themselves would lose of energy. The passage must explain more persuasively to reach the cited conclusion.
