Studies of

FUNAI, the Brazilian agency that regulates contact between the indigenous tribes and the outside world, and that the samples were being distributed for a fee with no benefit to the Karitiana, giving rise to claims of biopiracy.[4] The same newspaper report claimed that further samples were taken in 1996 by Dr. Hilton Pereira da Silva, a doctor on a documentary film crew, on the promise of medicinal supplies that were never fulfilled.[5] A response from Dr. Silva suggests that the news story was faulty and the medicinal samples he took were never used for any commercial purpose.[6]

Origins

A 2015 genetic study reached a surprising conclusion about the origins of the Karitiana people. While the Karitiana people are closely related to other Native Americans, they share closer relations to Southeast Asians & Polynesians compared with other Native Americans which are closest to Siberians and Northeast Asians.[7][8]

A study by Iosif Lazaridis (2014) found Karitiana to carry Mal'ta MA1 (41%) admixture while the other geneflow in Karitiana appears to have an Eastern Eurasian origin.[9] A study by Kanazawa-Kiriyama et al. (2017) detected gene flow from Karitiana to Mal'ta MA1 (21%) which is in the reverse direction of what was reported in previous studies such as Raghavan et al. 2014 who used a much larger sequence data. The authors speculate that the inverse flow could be due to Ancient Beringian migration in a westward migration into Eurasia.[10]
