Abstract:

Recent research on the Cambrian explosion, which occurred over 500 million years ago, is changing our understanding of evolution and the history of animal life. Geochemist Justine Ries sampled ancient rocks in Namibia and found evidence of sulfur isotopes. His findings provide insight to the environmental conditions of the Cambrian explosion.
