As Professor Osborn says: "the structure of the hand is a matter of the highest interest in connection with the implement-making powers of the Neanderthals". He notes that in the large and robust Neanderthal hand, "the joint of the metacarpal bone which supports the thumb is of peculiar form, convex, and presenting a veritable convex condyle, whereas in the existing human races the articular surface of the upper part of the thumb joint is saddle-shaped, that is concave from within backward, and convex from without inward". The Neanderthal fingers were "relatively short and robust".[5]

The Crô-Magnons present a sharp contrast to the Neanderthals. In all essential features they were of modern type. They would, dressed in modern attire, pass through the streets of a modern city without particular notice being taken of them. One branch of the Crô-Magnons was particularly tall and handsome, with an average height for the males of 6 feet 1-1/2 inches, with chests very broad in the upper part, and remarkably long shin-bones that indicate swiftness of foot. The Neanderthals had short shins and bent knees, and their gait must have been slow and awkward. The Crô-Magnon hand was quite like that of the most civilized men of to-day.
It is of importance to bring out these facts in connection with the study of the development of early civilization in our native land, because of the prevalence of the theory that in collections of stone implements, dating from remote Palæolithic times till the Neolithic Age, a complete and orderly series of evolutionary stages can be traced. "As like needs", says one writer in this connection, "produce like means of satisfaction, the contrivances with which men in similar stages of progress overcome natural obstacles are in all times very much the same."[6] Hugh Miller, the Cromarty stonemason and geologist, was one of the first to urge this view. In 1835, he wrote in his _Scenes and Legends_, (1st edition, pp. 31, 32):
"Man in a savage stage is the same animal everywhere, and his constructive powers, whether employed in the formation of a legendary story or of a battleaxe, seem to expatiate almost everywhere in the same rugged track of invention. For even the traditions of this first stage may be identified, like its weapons of war, all the world over."[7]
