Phillipson's observation holds for Greenberg, Renfrew, and for others of their ilk, EVEN IF they are "pointing the way to an important methodo- logical opportunity. As the Wegener case shows, even a well-argued and potentially productive hypothesis can still fail to "make a contribution" if it does not cross the threshold of connectedness with the body of already accepted hypotheses at the time. Greenberg and Renfrew are egregiously short on such connectivity. I regret the following ad hominem remarks, but it is necessary to make them to show this particular problem in the clearest light. The root cause of Renfrew's and Greenberg's failure to gain acceptance for their ideas -- Cavalli Sforza is another matter -- is that they are lazy. They have indeed glimpsed certain possibilities and syntheses. But they have laid their work on the table in the shoddiest of states, with little attention to the historical details as they are understood by informed specialists. Scott DeLancey and Jeffrey Wills have already described Greenberg's sins of ommission and commission in the comparative vocabularies of _Language in the Americas_. Let me cite a typical gaffe of Renfrew's. In the article he published in the January issue of _Scientific American_, he explains the dispersal of the "Na-Dene" language stock as one of the "climate-related dispersals" of the late Holocene. By this he means that, like the expansion of the Eskimo-Aleuts along the Arctic coast, or of other language families in Siberia, the Na-Dene expansion was probably motivated by the opening up of an ecological niche on the northern periphery of human settlement. The initial Na-Dene dispersal, he believes, represents "an early adaptation to the tundra environment." -- Plausible enough to the non-specialist, but the "Na-Dene" language family is a historic relationship linking Athabaskan, Eyak, and Tlingit (some--including Greenberg--also add Haida). Of these Na-Dene subgroups, only Athabaskan has a "tundra" location; the other languages are deeply entrenched in Northwest Coast environments. Renfrew presumably derives the latter from the former, by social mechanisms unspecified. While the origins of Northwest Coast populations are far from clear (here is where genetics may have a lot to say), this is certainly not the most likely scenario. This, however, is a small embarrassment compared to what comes next. To explain the wide dispersal of Athabaskan speech communities throughout much of Western North America -- including enclaves on the Pacific coast of Oregon and California as well as the Navajo and Apache of the Southwest -- Renfrew invokes another mechanism, "elite dominance," by which he means military conquest and similar agressive expansions of populations. I cite the passage in full (p.120): > Later, when climate or ecological factors rendered the area [i.e., > the "tundra"] less hospitable to them, they moved south. Some speakers > of Proto-Na-Dene penetrated as far as Arizona and New Mexico. Elite > dominance, amplified by horeseback riding, accounts for the presence > of the cultures related to this language group throughout much of the > continent. This howler, I think, gives the game away. Renfrew is so profoundly ignorant of North American culture history that he believes (a) that the Athabaskan expansion of ca. 700-1200 AD was part of the "Proto-Na-Dene" expansion of 2000 to 2500 years earlier (to cite the usual glottochronological estimates); and (b) that this was accomplished by Genghis-Khan-like mounted horse warriors, when every schoolchild, at least in the United States, knows that the horse was brought to the Western Hemisphere by Europeans after 1492. In other words, Renfrew couldn't be bothered to look up some elementary facts in a desk encyclopedia before commiting his "new synthesis" to writing in a journal that has a circulation in the millions. The sad truth is, both Renfrew and Greenberg have taken advantage of their considerable seniority (both Renfrew and Greenberg are well past 60 and heaped with academic honors) to publish and publicize some half-baked, overweening claims to significant breakthroughs. In so doing, they have not only failed to gain acceptance for what might well be "true" hypotheses, but have brought a certain odor of disrepute on the whole enterprise of interdisciplinary prehistory. Historical science must be cumulative, and new hypotheses and syntheses must work hard to integrate with previous schemata. Historical facts will not go away or change their color to suit the integrating fad of the day, and most of the hypotheses we work with in one generation will be equally "true" (or "false") in the next. A meaningful and productive marriage of genetics, archaeology, and historical linguistics can only be the product of years of research, by teams of researchers confident of the worth of the enterprise and respectful of every shard of data. Arrogant balderdash, promulgated largely in a journalistic mode, cannot speed this process, and may indeed significantly retard it by stirring the anger and resentment of the very individuals on whose specialized work it must build.
