  PRIMEVAL 
  MAN. 
  

  

  different 
  species, 
  even 
  when 
  standing 
  in 
  close 
  

   natural 
  relation 
  to 
  each 
  other, 
  is 
  absolutely 
  

   forbidden 
  by 
  the 
  sentence 
  of 
  sterility 
  which 
  

   Nature 
  pronounces 
  and 
  enforces 
  upon 
  all 
  

   hybrid 
  offspring. 
  And 
  so 
  it 
  results 
  that 
  Man 
  

   has 
  never 
  seen 
  the 
  origin 
  of 
  any 
  species. 
  

   Creation 
  by 
  birth 
  is 
  the 
  only 
  kind 
  of 
  creation 
  

   he 
  has 
  ever 
  seen 
  ; 
  and 
  from 
  this 
  kind 
  of 
  

   creation 
  he 
  has 
  never 
  seen 
  a 
  new 
  species 
  

   come. 
  And 
  yet 
  he 
  does 
  know 
  (for 
  this 
  the 
  

   science 
  of 
  Palaeontology 
  has 
  most 
  certainly 
  

   revealed), 
  that 
  the 
  introduction 
  of 
  new 
  species 
  

   has 
  been 
  a 
  work 
  carried 
  on 
  constantly 
  and 
  

   continuously 
  during 
  vast 
  but 
  unknown 
  periods 
  

   of 
  time. 
  The 
  whole 
  face 
  of 
  animated 
  nature 
  

   has- 
  been 
  changed, 
  not 
  once, 
  but 
  frequently; 
  

   not 
  suddenly 
  for 
  the 
  most 
  part, 
  perhaps 
  not
