In DNA and American Ancestry, TallBear
argues for the inadequacy of using DNA testing for determining Native American
citizenship. The big problem is that, race and ethnicity are not completely
determined by genetics. She mentions that although genetics are supposed to
tell where people were originated in the past, the fact that human beings move
around makes things more complicated. Using DNA testing to determine racial and
ethnical identity implies biological essentialism and ignores the social and
cultural factors of human communities. Furthermore, TallBear points out that
although DNA fingerprint tests are sometimes regarded an objective criterion in
kinship tests, they are in fact not objective, and that to consider them as
superior to other criteria for enrollment purposes “gives priority to
techno-scientific knowledge of certain kinship relations over other types of
knowledge and relationships”. Another drawback of genetic ancestry testing that
she mentions is that by only identifying biological descent along strict
bloodlines, it narrows down ones’ links to ancestors. TallBear finally compares DNA
testing to blood quantum testing, claiming that DNA testing can be even more
problematic although it has started to take the place of blood tests.
In Native American DNA: Ethical, Legal, and Social Implications of an Evolving Concept, Bardill
shows very similar concerns regarding the DNA tests in determining Native
American ancestry. I think TallBear’s and Bardill’s worries can be grouped into
roughly two categories: technical issues, such as the inadequacy of data and
the information stored in certain genes, which should be left for scientists,
statisticians and engineers, and the cultural implications of DNA testings.
Bardill echoes TallBear’s idea that the making of a community is not purely
biological, and therefore DNA evidence alone is not enough for determining
ancestry. Morever, she mentions the “power structure that puts scientists on
the top of the recreated colonial chain” in the practice of using DNA to
determine Native American ancestry.
Bolnick et al. raise some similar concerns. They point out that the
tests can provide information of some but not all of the subject’s ancestry.
Like TallBear and Bardill, they also argue that statistically some of these
tests are not qualified be used for diagnostic inferences, and that social and
cultural experiences are important factors in influencing racial identity
besides biology. They also mentioned the effects of the commercialization of
these tests. They argue that financial incentives might influence how the tests
are done and interpreted and make peer-review hard to achieve. For these
reasons, the authors urge the scientific community to speak out about the
limitations of genetic testing.
