Differences that were already noted include size, gestation time, and time spent in courtship display, but these differences did not lead the team to find a way to save the biologically threatened species of chipmunks that live on St. Kitts. As a result of this study, the researchers began to understand why the two closely related species were having so much trouble mating.
