It seems clear that the production of blade tools did not immediately swamp the set of older habits in Europe, too; the use of flake tools also continued there. This was not so apparent to the older archeologists, whose attention was focused on individual tool types. It is not, in fact, impossible--although it is certainly not proved--that the technique developed in the preparation of the Levalloisian tortoise core (and the striking of the Levalloisian flake from it) might have followed through to the conical core and punch technique for the production of blades. Professor Garrod is much impressed with the speed of change during the later phases of the last glaciation, and its probable consequences. She speaks of “the greater number of industries having enough individual character to be classified as distinct ... since evolution now starts to outstrip diffusion.” Her “evolution” here is of course an industrial evolution rather than a biological one. Certainly the people of Europe had begun to make blade tools during the warm spell after the first phase of the last glaciation. By about 40,000 years ago blades were well established. The bones of the blade tool makers we’ve found so far indicate that anatomically modern men had now certainly appeared. Unfortunately, only a few fossil men have so far been found from the very beginning of the blade tool range in Europe (or elsewhere). What I certainly shall _not_ tell you is that conquering bands of fine, strong, anatomically modern men, armed with superior blade tools, came sweeping out of the East to exterminate the lowly Neanderthalers. Even if we don’t know exactly what happened, I’d lay a good bet it wasn’t that simple. We do know a good deal about different blade industries in Europe. Almost all of them come from cave layers. There is a great deal of complication in what we find. The chart (p. 72) tries to simplify this complication; in fact, it doubtless simplifies it too much. But it may suggest all the complication of industries which is going on at this time. You will note that the upper portion of my much simpler chart (p. 65) covers the same material (in the section marked “Various Blade-Tool Industries”). That chart is certainly too simplified. You will realize that all this complication comes not only from the fact that we are finding more material. It is due also to the increasing ability of men to adapt themselves to a great variety of situations. Their tools indicate this adaptiveness. We know there was a good deal of climatic change at this time. The plants and animals that men used for food were changing, too. The great variety of tools and industries we now find reflect these changes and the ability of men to keep up with the times. Now, for example, is the first time we are sure that there are tools to _make_ other tools. They also show men’s increasing ability to adapt themselves. SPECIAL TYPES OF BLADE TOOLS
