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.
The article states that Agnostids, a group of marine animals which became extinct 450 million years ago. The passage mentions three theories about agnostics' way of living. However, the professor refutes each of these theories.
First, the reading claims that the agnostics probably were free-swimming predators, and they chased little animals like other primitive arthropods were solid swimmers and active predators. However, the professor refutes this idea by saying that we know that other arthropods have large eyes, but the eyes of Agnostids are too small. Some of them were blind, so they should have another organ help them prey, and there is no evidence of fossil record of their particular prey organs.
Second, the article posits that the agnostics, like other primitive arthropods, may have inhabited on the seafloor. In contrast, the professor says that the marine animals that live on the seafloor don't could move very fast and far. However, Agnostids were able to live in various areas. That spread across a far distance, showing that they could move fast so they couldn't be seafloor dwellers.
Finally, the passage claims that Agnostids may also be parasites living on and feeding larger organisms like primitive and more extensive arthropods. On the contrary, the professor refutes the argument by saying that the population of parasites can't be too much because the parasites can kill the host organism they live. But results show that Agnostids populations were large so that they couldn't be parasites.
