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 several different theories about how the Agnostids ate, behaved, and lived and provided three reasons for support. However, the professor explains that these theories had severe weakness and refutes each author's reasons.
First, the reading states that the Agnostids were Free-swimming creatures since there were plenty of smaller organisms in the ancient ocean for them to feed on. The professor refutes this point by stating that they were advanced-swimming animals; due to the well-developed eye, they could track prey and feed them. In Agnostid's fossil, the scientist did not find any sensory organ to catch prey.
Second, the article claims that they dwelled on the seafloor and might have survived by eating dead animals or feeding on bacteria. However, The professor contends that the floor-dweller animals can not both move very fast and go far away, so the studies have shown the Agnostids spread all over the sea in a large distance.
Third, the reading avers that the agnostids were parasites creatures and feed off larger fish or other animals. The professor opposes this point by saying that the parasite population is not very large and limited, although scientists have found the vast and generous size of the population this creature thereby, we role out the last option, for if this was true, the agnostids killed of all organism such as fish.
