  But whales have, as in all mammals, median elements that were originally
not paired, and a slit would be secondary to the nature as a single
element, not a reversal to an original condition of paired xiphisternal
bones. Do you have a citation for the above?

  Little steps are often the hardest to take.  We are too used to making leaps 
in the face of adversity, that a simple skip is so hard to do.  We should all 
learn to walk soft, walk small, see the world around us rather than zoom by it.
