And yet all these diversefore-feet, as also the hand of the Ape (Fig. 271) and thehuman hand (Fig. 272), have originated from the samecommon live-lingered parent-form. This is proved, not onlyby the rudiments of the aborted digits, but also by thehomologous disposition of the wrist-bones (Fig. 273, a-p).(Vide supra, p. 124.) The same story is also told by the germ-history of thelimbs, which is originally identical, not only in all Mammals,but in all Vertebrates. However different the limbs of thevarious Skulled Animals (Cvaniota) afterwards appear intheir fully developed state, they nevertheless all originatefrom the same simple rudiment. (Cf.
