Smith a co-author in proof of concept demonstration that epigenetic changes (cytosine methylation) can be found in ancient DNA in 2015. journals.plos.org/plosone/article?id=10.1371/journal.pone.0125344

The Wari Empire of the Peruvian Andes proves site for project studying epigenome and its relation to violence. Extreme changes in violence as evidenced by cranial trauma.

Quantitative work on violence in Wari is from Vanderbilt bioarchaeologist Tiffiny Tung sciencemag.org/news/2016/08/waris-grisly-end-fall-south-american-empire onlinelibrary.wiley.com/doi/abs/10.1002/ajpa.20565

Smith's Wari study shows major decline in LINE-1 methylation over the Wari errors, the expected response to worsening diet and increasing violence. meeting.physanth.org/program/2018/session33/smith-2018-line-1-methylation-in-ancient-dna-reflects-sociopolitical-transformation-in-peru.html

Meanwhile, a new study (2017–) of epigenetic of the effects of the Trail of Tears forced removal on descendant populations.

Initial results of Epigenome Wide Association Study... Removed/Non-removed populations don't cluster. But clusters of epigenome in local communities even when genetically dissimilar.

And... 200+ regions of epigenome significantly impacted by removal.

Smith: "rampant misappropriation of indigenous identity" via genetic claims in ignorance of tribal belonging, indigenous culture.

Blood banks as a site for blood quantum-labeled blood banks. Generally scientific work has preferentially consumed "pure blood" samples as representative of what indigeneity is.

Data from the re-study finds much more genetically diverse indigenous populations and presence of non-indigenous ancestry.

Smith: "So we asked, what would happen if... we did away with purity rubrics [and] center tribal sovereignty."

Actually existing population of tribally affiliated Native Americans is highly diverse in genetic ancestry. But the diverse majority left out of prior genetic studies.
