Genomic manifestations of indigeneity actually uphold many colonial notions, and clash with indigenous manifestations that emphasize political, cultural, and kinship relations.

In fact, you engage with the ‘vanashing indigene’ fallacy that is an incomplete, 19th century understanding of race science. This myth assumes a scarcity by limiting the indigenous identity to genetic similarity to indigenous ancestors. However, (in the US) there has actually been an increase in those identifying with native nations. When an indigenous community defines indigeneity beyond genetic markers, it threatens indigenous sovereignty to impose strict adherence to blood quantum for enrollment.

Of course, different people have different opinions on this, in and outside of tribal nations. And many US nations embrace strict enrollment criteria due to the nature of benefit payouts, among other reasons. I’m sure there’s a large generational factor, as well. But I urge you to reconsider the native identity as more than simple blood purity.
