Data demolishes dogma, July 18, 2004
As a young science, archaeology is necessarily dynamic. New discoveries, fresh insights, novel concepts emerge with almost dizzying frequency. Science is supposed to work on hypothesis testing - evidence confirms or refutes ideas. To discover that entrenched dogmas have been established, battlelines drawn and still contested, careers launched and destroyed is disheartening. To realise that the issue centres on a few stone tools renders the situation almost ludicrous - until we remember archaeology is the study of humanity. And humans, as Adovisio points out vividly, can cling tenaciously to favoured ideas - particularly those concerning humanity.Adovasio briefly relates the African origins and distribution of humanity across the globe. However, this story truly starts with the 1937 discovery of some finely crafted stone spearpoints in New Mexico. Debate over Indians as "noble savage" or "barbarous native" was sharply interrupted by this find. The workmanship and novel design of the "Clovis Points" demanded reconsideration of Native Americans - particularly of their origins and dispersal in the Western Hemisphere. Knowledge of the extent of the massive glaciers covering North American many millennia ago left but a small time window for Asian peoples to cross the Bering land bridge exposed during the glacial period. Who were these people? Adovasio asks. When did they arrive? How long did it take them to inhabit the hemisphere? What was their environmental impact? All these questions have been asked for many years. Adovasio's own research made a significant contribution when he excavated a rockshelter at Meadowcroft, Pennsylvania. Artefacts there were dated to a time far earlier than the Last Glacial Maximum [LGM] of just over eleven thousand years ago. Other sites, most notably the Monte Verde site in Chile have added data positing an earlier emigration from the Old World to the New. All this new information has challenged the dogma of "Clovis" being the "earliest Americans". It's not just an academic debate, Adovasio points out. Questions of site selection, investigation, testing procedures, retention of artefacts and human remains have all be raised. Indeed, with the Native American Graves Protection and Preservation Act [NAGPRA] some of these issues have been enshrined in law. He examines all the issues in exquisite detail, readily dismissing the more bizarre, such as the contention that the Western Hemisphere is the cradle of all humanity. Data must not only support or demolish dogma, it must support or demolish poorly conceived law. Adovasio's narrative becomes vigorously polemical at times. His stridency is forgiven when you recall he's spent three decades of defenders of the Clovis Bar shutting their minds to evidence - his and that of others. Although this is hardly an academic study, his assemblage of evidence and logic underpinning his assertions is a standard that any researcher would do well to review. He gives Paul Martin's "Pleistocene blitzkrieg" of the new human arrivals a thorough airing, but rejects it. In Adovasio's view, it was the climate or disease that drove the large fauna extinct, not human hunting. He examines a wide variety of emigration scenarios, including the "coastal enclave" idea, in explaining how this Hemisphere was populated. He admits defeat in selecting any one, but declares the first humans arrived here before the LGM. Only from that basis, he argues, can we establish not only when humans occupied this region, but how. This book is both a scholarly and entertaining read. Adovasio builds his case well, even adding cartoons to his collection of photographs and diagrams. Instead of footnotes, he provides per-chapter references, a nuisance to the novice in this topic. [stephen a. haines - Ottawa, Canada]
