We have no idea what became of this early Paleolithic man. None of the present-day races in any of the areas where he existed, even in India, can be considered as descending from him. The implements of this extinct race have been discovered in the caves of England, France, Switzerland, Belgium, and Southern Germany, mostly in the undermost layers of soil deposit. Above this lowest level of culture, frequently separated from it by a thick or thin layer of stalactite, is a second layer containing implements. Belonging to a later period, these are far more skilfully crafted and made of various materials. True, the stone implements are not polished, but they are designed and executed so as to be more expedient. Next to these we discover spear- and arrow-heads of stone, reindeer antlers and bones, daggers and sewing needles made from bones or antlers, as well as necklaces made of bored animal s teeth, etc. Some implements bear vivid drawings of animals reindeers, mammoths, aurochs, seals, whales and hunting scenes with figures of naked men, even the beginnings of sculpture in horn. Early Paleolithic man occurred together with animals of largely southern origin, while late Paleolithic man existed alongside animals of northern origin: two extant species of northern bears, the polar fox, the glutton, the snow owl. Late Paleolithic. man probably moved down from the north-east together with these animals. The Eskimoes are probably his last surviving descendants. The implements of both cultures correspond fully not only in isolated instances, but as a totality. The same is true of the drawings. Both derived their sustenance from nearly the same animals, and the mode of life of the extinct race, insofar as we can ascertain it, was absolutely the same.
