   When he started compiling an online database of seashells 15 years ago, Dr. Gary Rosenberg did not envision that his meticulous record-keeping would eventually shed light on a 40-year-old evolutionary debate. The debate involves the mechanism underlying the island rule: that small animals isolated on islands evolve to be larger than their mainland relatives, and large animals evolve to be smaller.
