Vine Deloria Jr.'s book is a very useful and merited challenge to a whole host of theories, especially the Bering Strait land bridge, magafauna extinction ("Overkill") and some other things in which U.S. racism, capitalist waste and ruthlessness towards the environment, and scientistic narrowness are shown to be the underlying roots of these theories. However, I can't help but feel that Deloria both throws the baby out with the bathwater based on a kind of "multicultural creationism". For example, his attacks on Stephen J. Gould are almost ridiculous at times (given his prominence, not as a mainstream Darwinian, but as a 'catastrophist' and anti-sociobiologist) and represent the fact that he never got past Gould's first collection of essays. Also, Gould and others have for years defended allopatric speciation, which would allow a species' 'gestation' in 5-10,000 years. This type of narrow, shotgun scholarship makes Deloria subject to exactly the type of criticism he so correctly levels at academia. Also, his knowledge of genetics and evolution seem to leave a lot to be desired, and he clearly does not expect the reader to be scientifically literate (otherwise, he would not be able to make some of the peculiar remarks he makes about speciation). Anyone familiar with modern biology cannot but be amazed at how his work is little more than a reworking of Christian Fundamentalist creationism (or vice versa). Having said that, Deloria's value as an anti-racist, as a defender of the worth and validity and richness of non-white, non-European sources of knowledge is more than worth the occaissional bad science and anti-intellectualism. All I can say is that this is essential reading for anyone learning about the material he covers, and for thinking about how racism and power can determine whose knowledge is 'myth and fantasy' as much as it determines who is the 'terrorist' and who is the 'freedom fighter'. A must read book.
