Essay topics: TPO-43 - Integrated Writing Task

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-day insects. However, the fossil information does not allow paleontologists to determine with certainty what agnostids ate or how they behaved. There are several different theories about how agnostids may have lived.

Free-Swimming Predators

First, the agnostids may have been free-swimming predators that hunted smaller animals. It is known that other types of primitive arthropods were strong swimmers and active predators, so it is reasonable that the agnostids may have lived that way as well And while the agnostids were small, sometimes just six millimeters long, there were plenty of smaller organisms in the ancient ocean for them to prey on.

Seafloor Dwellers

Second, they may have dwelled on the seafloor. Again, there are examples of other types of primitive arthropods living this way, so it is possible that agnostids did too. On the seafloor they would have survived by scavenging dead organisms or by grazing on bacteria.


Third, there is the possibility that the agnostids were parasites, living on and feeding off larger organisms. One reason that this seems possible is that there are many species of modern-day arthropods that exist as parasites, such as fleas, ticks, and mites. The agnostids might have lived on primitive fish or even on other, larger arthropods.

The reading passage claims that the Agnostids were a marine animal about 450 million years ago and because there are not any significant fossil records of them, so, it is not simple to clarify the way of eating or the space of they lived. In this way the reading claims that there are three specific reason for possibility of the lifestyle of these creatures. While, the lecturer on the other hand, claims that these three argument are erroneous and she states theses features undoubtedly are not possible for agnostids living situation.

First, the lecture claims that the possibility of being agnostids a free-swimming predator is nearly zero. Because, these modern predators have an incredibly powerful and well developed eyes for chasing the prays while, according to the fossil records, the agnostids had a exceptionally minuscule, tiny eyes which by these eyes they were virtually blind which as one of the consequences they can not find the prays by eye chasing. And maybe there was other chasing mechanism which it is not supported by any evidences, so this supposition is also ridiculous as a scientific prospective.

Secondly, the lecturer refuses the seafloor dwellers assumption and claims that it is wrong reason either. Most primitive arthropods had this way of living and for that they were so slow. Meanwhile, according to the evidenced, they can not go very long distance while the agnostids had a vast geographical area which they can go through it and gathering the foods and moreover as a mater of the fact, they were remarkabely a speady creatures for some specific body statues.

Finally, the speaker is not convinced by the parasite argument in the reading which claims that the modern parasites like fleas, taiks and mites and also the agnostids on the other hand were the same kind. While, as the parasites had a special behavior that they absolutely kill their host, so they have not an abundant population also, they had a lot of different kinds of the parasites. While, the agnostids had a widespread population in one area as the fossile recored show this fact by gathering prolifically remnants of the agnostids in their houses.

Conclusively, it can be said that the whole argument of the reading is misleading and it is very crucial that the scientist have an eye on this fact.
