These rude tools and weapons of Paleolithic man, found in gravel beds and in caves, are the very oldest things in existence shaped by human hands.

Among the animals which lived with him on the continent of Europe—we know most of Paleolithic man there—were the mammoth, the cave bear, the elk, the rhinoceros, the wild horse, and the reindeer; species which are no longer found in the regions where primitive man hunted them. As the climate gradually grew warmer they either became extinct or retreated up the mountains or migrated towards the north.
