  So ... another apomorphic _suite_ rather than a single apomorphy; what's
more, an "apomorphy" that has nothing to do with the name ("spheniscus"
comes from the Greek for "wedge-like," which can be a referrence to the
wing shape [not function] or to the bill shape).

  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.
