Yanomami Blood Controversy
Yanomami Blood Controversy (1967-2010) was a controversial study involving anthropologist Napoleon Chagnon and geneticist James Neel. who took blood samples of the Yanomami without their consent. Since this has been uncovered, both researchers have gained a substantial amount of backlash and accused of performing unethical practices. The return of the blood samples took almost four decades so they could be turned over to the Yanomami.

Background
In the years between 1960 and 1970, Chagnon and Neel obtained the blood samples from the Yanomami tribe that reside at the border of Brazil and Venezuela, believing that it would help them with their current health situations, the Yanomami's blood were retrieved. The Yanomami were the main center of an ethnographic research during the time and Chagnon has studied the tribe for several years. They initially had brought pots and pans and their aide to battle the diseases ravaging their tribes but in exchange they wanted blood samples. The Yanomami never received help. The blood samples were never used in ways that would aid the Yanomami and were mostly used for other types of studies that benefitted the researchers own personal needs. Another use for the blood was that Neel wanted to explore the genealogy of the tribe. It was until several years later that the Yanomami learned that their blood were being kept in refrigerators in several universities, most notably Pen State. The Yanomami claimed that the researchers didn't specify a clear reason why their blood was being drawn.

Affects on the Yanomami
Obtaining the blood of the Yanomami, caused several problems within the tribe. Their funerary processes are very scared. When one of the members of the tribe dies, they and all of their belongings are burned in order to ensure that the individual leaves this world. Since blood samples were taken from now deceased individuals, the process of their metamorphism has failed and the individual could not leave this world.
