The American Anthropological Association is called on to take action on the allegations made by Patrick Tierney, an investigative journalist, about the genetic and medical experiments conducted by James Neel, Napoleon Chagnon, Marcel Roche and Timothy Asch among the Yanomami people of Venezuela. Tierney accuses the Yanomami project of being a secret experimental program that is a continuation of the Atomic Energy Commission. The article presents an accusation stating that Neel's associate, Marcel Roche, is guilty of injecting the people of Venezuela with radioactive isotopes in order to study the effects of radiation. Evidence that Neel and Chagnon probably started a measles epidemic is also presented by Tierney. Questions arise concerning the theoretical motives of the project, the blatant disregard of ethics , and the dangers of uncontrolled science and ego.
