Pennsylvanian sea urchins are echinoderms that can be found today in all seas of the world. Sea urchin fossils dating back 300 million years reveal that these invertebrates with their complex structures have existed for millions of years. During all that time, no change have occurred in their structure, and they have undergone no intermediate stages. Darwinists are desperate when confronted by these fossils, for they prove that the evolution process has never existed.
