Darwin’s Dilemma – The Significance of Sponge Embryos

Dr. Stephen Meyer, author of Darwin’s Doubt, talks about a significant discovery in China of tiny sponges in the pre-Cambrian layer of the fossil record. Having studied these fossils alongside Chinese paleontologist and Cambrian explosion scholar Jun-Yuan Chen, biologist Paul Chien describes the technique used to analyze the sponge embryos’ complexity.
