One of the most ancient of all known fossils is the trilobite. Fortunately, a large number of well-preserved examples exist that allow a detailed study of this complex animal. As a result, much is known about it, including its external morphology and even its advanced, welldesigned, complex eye. Research on the trilobite eye shows that it is far more complex and better designed than thought, even just a few years ago. This paper concludes that no evidence exists in the fossil record for trilobite evolution from lower forms of life and that the first trilobite was unequivocally a trilobite.
