Perhaps a partial explanation of this matter may be found when we consider all the circumstances of the case. The origin of man is generally assigned to some tropical country. Sir John Lubbock thus speaks of it: “Our nearest relatives in the animal kingdom are confined to hot, almost tropical climates; and it is in such countries that we are, perhaps, most likely to find the earliest traces of the human race.”24 This is also the opinion of other eminent scholars. M. Quatrefages thinks that man probably originated in Asia. He points out, however, that, during Tertiary times, the climate was much milder, and man might have originated in Northern Asia.25 Now, if it be true that a great mass of land has disappeared beneath the waves of the Pacific, why may we not suppose that, if this sunken land was not the original home of man, it was at a very early time inhabited by him; that here he passed through his experience in savagism?26 We know how suited the islands of the Pacific are to the needs of a savage people; and we must not lose sight of the probable ease with which they could reach the coast of California—and also of what Dr. Cooper has told us of the climate and geographical surroundings of California at that early time. So it may not be unreasonable to suppose that man reached California long ages before he wandered into Europe, and so reached the Neolithic stage of culture much earlier than he did in other parts of the world.27 It might be objected, that if a people in the Neolithic stage of culture lived in California in the Pliocene Age, they ought to have reached a very high stage of culture indeed when the Spaniards invaded the country. This is what we would expect had they been left to develop themselves. The great geographical changes that took place near the close of the Pliocene would cut off the primitive Californians from the Asiatics. Not only was the land connection—if it indeed existed—now destroyed, but causes were changing the climate. Ice and snow drove from the north life of both animals and plants, and for an entire geological period communications with Asia by way of the north must have been very difficult, if not cut off altogether. Who can tell what changes now came to the Asiatic branch of these people? We are but too familiar with the fact that nations and races sicken and die: many examples could be given. The natives of the Sandwich Islands seem doomed to extinction. In a few centuries, the Indians of America will live only in tradition and song.
