TupiGuarani Brazilian ethnic groups: Asurin, Parakan, Chasteen (2004:4): "between the White elite and the mass of [Indigenous Americans] and Negroes there existed by 1700 a thin stratum of population subject neither to Negro slavery nor [Indigenous American] tutelage, consisting of the products of racial interbreeding among Whites, [Indigenous Americans], and Negroes and defined as mestizos, mulattoes and zambos (mixture of [Indigenous American] and Negro) and their many combinations.

Native Americans are 500% more likely to experience alcohol-induced deaths and 20% more likely to die from drug use, according to a 2021 report by Arizona's Department of Health Services. Genetic evidence for Paleo-Indigenous Americans consists of the presence of apparent admixture of archaic Sundadont lineages to the remote populations in the South American rain forest, and in the genetics of Patagonians-Fuegians. Haplogroup R1 is the second most predominant Y haplotype found among Indigenous Americans after Q (Y-DNA). It has been identified in many dogs with white or merle coloring around the head.

[59], Some researchers feel that this may indicate that the Na-Dene migration occurred from the Russian Far East after the initial Paleo-Indigenous American colonization, but prior to modern Inuit, Inupiat and Yupik expansions. [19] Observed is a decreasing genetic diversity as geographic distance from the Bering Strait occurs, as well as a decreasing genetic similarity to Siberian populations from Alaska (the genetic entry point). The authors explained that these previous claims were based on a misinterpreted genetic echo, which was revealed to represent early East-Eurasian gene flow (close but distinct to the 40,000 BCE old Tianyuan lineage) into Aboriginal Australians and Papuans. However, Heterochromia caused by an underlying disease or an injury is a cause for concern because an injury to the eye can be fatal.
