Figure 1 The Evolution of an Enhancer and Skeletal Variation (Top) Illustration of the cross between the marine and freshwater sticklebacks used for the quantitative trait loci analysis that led to GDF6 enhancer identification. Note the difference in armor plates in the flank of the two fish populations. (Lower-left) Mouse hindlimb autopod showing the expression pattern in the posterior digits driven by the conserved mammalian enhancer deleted in humans. (Right) Comparison between human and chimpanzee hand and feet morphology. The posterior digit size is reduced in humans, but not in chimpanzees, thus correlating with the acquisition of bipedalism.
