I would use this current science discovery during a unit on speciation and/or genetics. I would love to hear students’ ideas as to what factors they think caused or resulted in the Cambrian Explosion. To my knowledge, much of the explanation for the appearance of so many new body forms in such a small period of time is not yet understood. Thus, students could apply their new knowledge of speciation and/or genetics to “unknown” areas of science in the search of greater understanding.
