Of especial geographic interest is the discovery by Nicolle and Sinel(47) of thirteen human teeth in a Mousterian cavern on St. Brelade's Bay, on the Island of Jersey,(48) which furnishes proof of the extension of the Neanderthal race to the Channel Islands, when these were, in all probability, still a part of the mainland. The teeth were associated with bones of the woolly rhinoceros, of the reindeer, and of two varieties of the horse, as well as with evidences of Mousterian hearths and flint implements. The distinctive features of the Neanderthal grinding-teeth are the stout size, deep implantation, and expanded form of the roots, which, with the heavy jaw, point to the toughness of the food and to the muscular strength exerted in mastication. The roots, instead of tapering to a point below, as in modern man, form a broad, stout column, supporting the crown, adapted to a sweeping motion of the jaw. This special feature alone would exclude the Neanderthals from the ancestry of the higher races. Thus, through a long series of discoveries, beginning in 1848 and rapidly multiplying during the last few years, we have found the materials for a complete knowledge of the skeletal structure of the men, women, and children of the Neanderthal race; we know the relative brain development as well as the stature of the sexes; we have determined that this race, and this only, extended over all western Europe during late Acheulean and the entire period of Mousterian times, and we have also learned that it was a race imbued with reverence for the dead and therefore probably animated by the belief in some form of future existence. CHARACTERS OF THE NEANDERTHAL RACE The skulls and skeletons(49) of Neanderthal, Spy, Krapina, Le Moustier, La Chapelle, La Ferrassie, and Gibraltar have so many distinctive features in common that it is beyond question that they must be classed in a closely related group. The distinctive features of this group are: First, features found also in the different existing races of man, but never in the anthropoid apes, and therefore human; second, features, all of which have never been found combined in any race of recent man, the group, therefore, represents a distinct species of man; third, features outside of the limits of variation in the recent races of man, and intermediate between them and the variation limits of the anthropoid apes.
