If I'm not mistaken, cell differentiation begins at the 32 cell stage. 
 Is this correct?  And if so, assume at the two-cell-stage there is 
separation of the cells resulting in identicle twins.  Will these two 
cells divide to the 16-cell stage before differentiation begins or 
will they divide to the 32-cell-stage.  In other words, is 
differentiation activated by the number of divisions or the number of 
cells?
