Both the reading passage and lecture discuss about several characteristics of agnostids, a group of marine species that became extinct long ago. The author presents some hypotheses regarding eating habit and behaviors of agnostids. However, the lecturer casts doubt on those theories and refutes each of them by providing several counter-arguments.
First of all, the reading posits that agnostids were active predators which lived by eating smaller organisms. In the contrary, the lecturer refutes the idea mentioning that it is required to have large well developed eyes and high quality vision to be a hunter. As agnostids' eyes were not well developed and they were almost blind, it is highly unlikely that they were active predators. She also points out to the fact that agnostids did not have other sensory organs required for hunting.
Secondly, the author brings up the idea that agnostids were seafloor dwellers and survived by eating dead organisms or bacteria. Nevertheless, the lecturer finds this idea dubious and she states that most of seafloor dwellers are slow and they are mostly localized to some places. However, agnostids were tremendously fast species and they were found across a large area. Thus it invalidates the assumption that agnostids dwelled on the seafloor as their nature contradicted general characteristics of seafloor dwellers.
Finally, according to the article, it is possible that agnostids were parasites and lived on primitive fish or other larger anthropods. On the other hand, the speaker dissatisfied with the idea and claims that if it is expected that population of parasite is small as if there are numerous members in parasite group might kill off the host they live on. She also points out the fact that vast amount of fossilized agnostids proves that population of those species were very large which invalidates the assumption that agnostics were parasites.
