�Evolutionary biology�s deepest paradox concerns this strange discontinuity. Why haven�t new animal body plans continued to crawl out of the evolutionary cauldron during the past hundreds of millions of years? Why are the ancient body plans so stable?� Jeffrey S. Levinton, �The Big Bang of Animal Evolution,� Scientific American, Vol. 267, November 1992, p. 84.

�Granted an evolutionary origin of the main groups of animals, and not an act of special creation, the absence of any record whatsoever of a single member of any of the phyla in the Pre-Cambrian rocks remains as inexplicable on orthodox grounds as it was to Darwin.� T. Neville George (Professor of Geology at the University of Glasgow), �Fossils in Evolutionary Perspective,� Science Progress, Vol. 48, No. 189, January 1960, p. 5.

b. Strange Cambrian fossils, thought to exist only in the Burgess Shale of western Canada, have been discovered in southern China. See:

L. Ramsk�ld and Hou Xianguang, �New Early Cambrian Animal and Onychophoran Affinities of Enigmatic Metazoans,� Nature, Vol. 351, 16 May 1991, pp. 225�228.

Jun-yuan Chen et al., �Evidence for Monophyly and Arthropod Affinity of Cambrian Giant Predators,� Science, Vol. 264, 27 May 1994, pp. 1304�1308.

Evolving so many unusual animals during a geologic period is mind-boggling. But doing it twice in widely separated locations stretches credulity to the breaking point. According to the theory of plate tectonics, China and Canada were even farther apart during the Cambrian.
