tion deeply hidden in the nuclear architecture, the enormously 

 complex physico-chemical structure of the genetic basis, or genes, 

 and therefore the origin of the individual, though obviously through 

 epigenesis, is fundamentally from a sort of preformed basis. We 

 no longer bother ourselves with the old conundrum as to which is 

 more complex, the egg or the adult, but recognize that each is com- 

 plex in its way — the simplicity of the egg being more apparent 

 than real, as is convincingly attested by every endeavor to analyze 

 cytoplasm, nucleus, chromosomes, genes, and beyond.
