This starfish fossil is about 500 million years old—a rare specimen whose characteristics have been very well preserved. The starfish"s characteristic five arms have come down to the present time unchanged. There is no difference between starfish that lived half a billion years ago and the starfish of today. Like hundreds of thousands of other fossils, this one also shows that living things did not evolve and have undergone no change for hundreds of millions of years.
