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-

The reading and lecture are both about Agnostids, and what kind of creature they were. The author of the reading believes that arthropods were primitive arthropods-relatives of present insects.The lecturer casts doubts made on the claims in the article. He thinks that Agnostids were not primitive arthropods.

First of all, the author points out that they were free swimming predators. It is mentioned that primitive arthropods would usually swim freely and find preys smaller than themselves. This point is challenged by the lecturer. He says that the Agnostids could not be predators, because most arthropods had very good eyes. Furthermore, she argues that the they usually had very bad eyes, even sometimes blind.

Secondly, the author contends that the Agnostids were seafloors surface dwellers. The article notes that the primitive Arthropods would usually act like this. The lecturer rebuts this argument. He suggests that the these creatures could never be seafloors dwellers Furthermore, he added that seafloor dwellers would usually be slow, and travel locally.

Finally, the author states that the Agnostids were parasites. The article establishes that again most primitive Arthropods were parasites. The lecturer, on the other hand posits that the parasites would usually have a small population. He puts forth the idea by mentioning that the they fossils show a huge community, which means they most likely would not be parasites.
