The volume of ancient genomic data from the Americas has increased by orders of magnitude, and the picture of the deep human history of the hemisphere continues to become more detailed and more complex.

The ethical frameworks for this research have evolved as well, though not uniformly and not always in directions that Indigenous scholars consider adequate.

Some research groups have developed extensive consultation protocols and long-term partnerships with Native communities that give those communities meaningful input into research design, data use, and publication.

Others have conducted research on ancient remains from the Americas with minimal or no Indigenous engagement, relying on the legal framework — which permits research on remains that predate NAGPRA’s coverage or that cannot be culturally affiliated under the law’s standards — as justification for proceeding without community consent.

The debate between these approaches reflects genuine disagreements about the appropriate balance between scientific freedom and Indigenous sovereignty — disagreements that are unlikely to be resolved by consensus in the near term.
