How does bat wing development differ from other tetrapod limbs? The humerus forms first, followed by more distal structures. The digits form first, followed by more proximal structures. Increased expression of Bmp2 drives more cell division in developing digits. Bat wing development does not differ from other tetrapod limbs; there is simple a gene that codes for longer digits.
