An early volume (the first?) in a new series which will feature a diversity of innovative studies with some preference toward the organismic level. In this investigation into butterfly color patterns, Nijhout (zoology, Duke U.) integrates the results of comparative morphology, experiments on pattern development, the genetics of color patterns, and theoretical modeling of pattern formation to show that the enormous diversity of natural patterns arises largely from quantitative variations in a small set of generating rules involving size, shape, position, and color.
