Cambrian Fossils Still a Dilemma for Darwinism 100 Years After Discovery of Burgess Shale

Exactly one hundred years ago leading American paleontologist Charles Doolittle Walcott (right) was hiking along Burgess Pass in the Canadian Rockies when he found a slab of shale containing fossil crustaceans. His interest piqued, Wolcott made return trips to the Burgess Shale in the following years where he ultimately collected tens of thousands of fossils. Many of these fossils were extraordinarily well-preserved, and they were mysterious. They included strange forms like Anomalocaris, Opabinia, Wiwaxia, and Hallucigenia. These fossils revealed a mystery: like other Cambrian fauna, these strange soft-bodied fossils appeared in the fossil record abruptly, without evolutionary precursors. Darwin himself was aware of this problem in his own day, writing that the lack of fossil evidence for the evolution of Read More ›
