Apparently the origin of such adaptive variations must be sought in mutations — the unadaptive mutations being eliminated in the struggle for Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Woodruff, Lorande Loss, 1879-1947.
