The Mystery of the Cambrian Explosion
Darwin’s Dilemma explores one of the great mysteries in the history of life: the “Cambrian Explosion,” the geologically-sudden appearance in the fossil record of most major animal phyla during a span of less than ten million years. The Cambrian Explosion, which took place about 530 million years ago, provides a major challenge to the traditional mechanisms of Darwinian evolution. In the words of one evolutionary biologist: “The extreme speed of anatomical change and adaptive radiation during this brief time period requires explanations that go beyond those proposed for the evolution of species within the modern biota.” (R. L. Carroll, “Towards a new evolutionary synthesis,” Trends in Ecology and Evolution, Vol. 15(1):27-32 (2000))
Darwin’s Dilemma provides a tantalizing glimpse into the world of the Cambrian explosion through computer animation and the amazing fossils in the Burgess Shale of British Columbia, Canada and the Maotianshan shales of Chengjiang, China.
