Although it's a quote from another site, I believe this is her viewpoint:
In the course of the debate, Bint links to several resources on Native identity. One is worth noting here:
Genetic "Markers"--Not a Valid Test of Native Identity
But there are problems with using genetics to determine whether or not one has Native American ancestry, and/or alternatively to determine tribal membership. The most obvious problem is that being Native American is a question of politics and culture, not biology; one is Native American if one is recognized by a tribe as being a member. And one is not necessarily a member of a tribe simply because one has Native American ancestors. Another problem is that genetic analysis, and some of the processes involved, can be problematic for indigenous people in terms of their own cultural knowledge. Put simply, there are things involved in genetic analysis that some indigenous cultures consider violations of their principles or values.
But the most important argument against this type of testing to establish tribal affiliations is that biology (and genetics) track just part of our tribal inheritance. These DNA tests treat Native American biology as though all Indians were essentially the same. But in reality, our traditions make us who we are, not just our biology.
The debate is long and difficult to summarize. But to support her claims with evidence, Bint eventually says
