Nassim Nicholas Taleb: “The math comes first, words later.”(facebook.com)

  For lay spectators, the row is a symptom of the long and controversial
  evolution of the very idea of evolution.  At root it is a dispute about
  whether natural selection, the theory of "the survival of the fittest" first
  put forward by Charles Darwin in 1859, occurs only to preserve the single
  gene. Wilson is an advocate of "multi-level selection theory", a development
  of the idea of "kin selection", which holds that other biological, social and
  even environmental priorities may be behind the process.
  
  But Dawkins is far from convinced: "Wilson now rejects 'kin selection' and
  replaces it with a revival of 'group selection' – the poorly defined and
  incoherent view that evolution is driven by the differential survival of
  whole groups of organisms."
