A friend tells you that he has found a small animal with a segmented body and jointed appendages. On the basis of these two features, he concludes that the animal is an arthropod. Evaluate his conclusion.
One reason that is cited for the evolutionary success of insects is that many young insects differ from adults in appearance and feeding methods.
