There is no agreement as to the racial affinities of the earliest migrants. Most anthropologists still believe they were Mongoloids and therefore what they call Indians. Some go to the other extreme and declare they were Australoid, Negroid, and/or Caucasoid. Some, like Hooton, say the stock was drawn from a mingling of the three races in Asia. He thinks they “may have received some Mongoloid admixture before reaching the New World, but this is doubtful.”[3] Many of the skulls of early man resemble in certain respects those of that late arrival, the Eskimo, just as the Eskimo resembles some specimens of Magdalenian man. The skulls of the Eskimo are long-headed, and have keeled vaults and prominent cheekbones. But most early craniums have three features that are lacking in the Eskimo—receding chins, slanting foreheads and heavy brow ridges—all stigmata of the Australoid-Melanesian. It is rather puzzling to note that these early skulls are found with the bones of extinct animals in South America, but seldom with such fossils in North America, while they are not found with Folsom or Sandia or any form of ancient point. (There seem few points of definite-early type in South America.) It is possible, as Howard suggested, that the North American hunters practiced exposure of the dead instead of burial, while early man to the south left more burials for us than the few that have been found. The Puzzle of the Querns The next puzzle lies in the milling stones. Man in America not only starts off with an exceptionally fine type of spear point to thrust into elephant or bison, and uses pressure flaking far more extensively than man in the Old World; in addition, he develops the type of milling stone, or quern, that does not appear in Europe until man is coming out of the Old Stone Age and entering the neolithic period of agriculture. Milling stones might be used as an argument against the early appearance of man in America if it could be proved that they were made to grind agricultural products; but no kernels of corn or other cultivated seeds have been found with these querns.
