had diverged from each other. Now, this divergence almost 

 certainly took })lace as early as the Miocene period, because in 

 the Upper Miocene deposits of Western Europe remains of two 

 species of ape have been found allied to the gibbons, one of 

 them, Dryojiithecus, nearly as large as a man, and believed by 

 M. Lartet to have approached man in its dentition more than 

 the existing apes. We seem hardly,, therefore, to have reached, 

 in the Upper Miocene, the epoch of the common ancestor of 

 man and the anthropoids. 



The evidence of the antiquity of man himself is also scanty, 

 and takes us but very little way back into the past. We 

 have clear proof of his existence in Europe in the latter stages 

 of the glacial epoch, with many indications of his presence in 

 interglacial or even pre-glacial times ; while both the actual 

 remains and the works of man found in the auriferous gravels 

 of California deep under lava-flows of Pliocene age, show that 

 he existed in the New World at least as early as in the 

 Old.i These earliest remains of man have been received 

 with doubt, and even with ridicule, as if there were some 

 extreme improbability in them. But, in point of fact, 

 the wonder is that human remains have not been found 

 more frequently in pre-glacial deposits. Referring to the 

 most ancient fossil remains found in Europe — the Engis 

 and Neanderthal crania, — Professor Huxley makes the follow- 

 ing weighty remark : "In conclusion, I may say, that the 

 fossil remains of Man hitherto discovered do not seem to me 

 to take us appreciably nearer to that lower pithecoid form, by 

 the modification of which he has, probably, become what he 

 is. " The Calif ornian remains and works of art, above referred 

 to, give no indication of a specially low form of man ; and it 

 remains an unsolved problem why no traces of the long line 

 of man's ancestors, back to the remote period when he first 

 branched off from the pithecoid type, have yet been discovered. 



It has been objected by some writers— notably by Professor 

 Boyd Dawkins — that man did not probal)ly exist in Pliocene 

 times, because almost all the known mammalia of that e})Och 

 are distinct species from those now living on the earth, 

 and that the same changes of the environment which led to
