"...anyone with even the most superficial acquaintance with embryology must have been struck by the marvelous way in which complexes of cells group themselves to form an eye that as yet has nothing to see, hands that have nothing to handle, feet that have nowhere to go, and so on. Everything, while contributing to the life of the embryo, seems subordinated to a life of a quite different and higher order yet to come. The embryo has an integrity dictated to it as it were by the future. The meaning of each organ is read back into it by the function it achieves after birth."- from Goddard's "The Meaning of Shakespeare"
