According to the punctuated equilibria model,

  1. A.    natural selection is unimportant as a mechanism of evolution.
  2. B.     given enough time, most existing species will branch gradually into new species.
  3. C.     most evolution occurs in sympatric populations.
  4. D.    most new species accumulate their unique features relatively rapidly as they come into existence, then change little for the rest of their duration as a species.
