This article is about a collection of soft-bodied fossils from the Burgess Shale in British Columbia, and likened such fossils to an explosion; hence the name, "Cambrian Explosion." The article considers how such an explosion may have happened. It also considers the discovery of other soft-bodied fossils in the world, and how these complex animals leave evolutionits scratching their heads. It concludes by suggesting these animals were pre-flood, and suddenly buried when the flood came.
