The stone tools help us most. They have lasted, and we can find them. As they come to us, from this cave or that, and from this layer or that, the tool industries show a variety of combinations of the different basic habits or traditions of tool preparation. This seems only natural, as the groups of people must have been very small. The mixtures and blendings of the habits used in making stone tools must mean that there were also mixtures and blends in many of the other ideas and beliefs of these small groups. And what this probably means is that there was no one _culture_ of the time. It is certainly unlikely that there were simply three cultures, “Acheulean,” “Levalloisian,” and “Mousterian,” as has been thought in the past. Rather there must have been a great variety of loosely related cultures at about the same stage of advancement. We could say, too, that here we really begin to see, for the first time, that remarkable ability of men to adapt themselves to a variety of conditions. We shall see this adaptive ability even more clearly as time goes on and the record becomes more complete. Over how great an area did these loosely related cultures reach in the time 75,000 to 45,000 or even as late as 35,000 years ago? We have described stone tools made in one or another of the flake and core-biface habits, for an enormous area. It covers all of Europe, all of Africa, the Near East, and parts of India. It is perfectly possible that the flake and core-biface habits lasted on after 35,000 years ago, in some places outside of Europe. In northern Africa, for example, we are certain that they did (see chart, p. 72). On the other hand, in the Far East (China, Burma, Java) and in northern India, the tools of the old chopper-tool tradition were still being made. Out there, we must assume, there was a different set of loosely related cultures. At least, there was a different set of loosely related habits for the making of tools. But the men who made them must have looked much like the men of the West. Their tools were different, but just as useful. As to what the men of the West looked like, I’ve already hinted at all we know so far (pp. 29 ff.). The Neanderthalers were present at the time. Some more modern-like men must have been about, too, since fossils of them have turned up at Mount Carmel in Palestine, and at Teshik Tash, in Trans-caspian Russia. It is still too soon to know whether certain combinations of tools within industries were made only by certain physical types of men. But since tools of both the core-biface and the flake traditions, and their blends, turn up from South Africa to England to India, it is most unlikely that only one type of man used only one particular habit in the preparation of tools. What seems perfectly clear is that men in Africa and men in India were making just as good tools as the men who lived in western Europe. EARLY MODERNS [Illustration]
