Note 3 — III THE DEMONSTRATIVE EVIDENCE OF EVOLUTION

I use the word "type" because it is highly probable that many forms of Anchitherium-like and Hipparion-like animals existed in the Miocene and Pliocene epochs, just as many species of the horse tribe exist now; and it is highly improbable that the particular species of Anchitherium or Hipparion, which happen to have been discovered, should be precisely those which have formed part of the direct line of the horse's pedigree.
