There are several major questions concerning the Darkness in El Dorado. For example, the Yanomami has acquired false nicknames over the years, such as the "fierce and intractable," and also the measles from secret experiments conducted by the Atomic Energy Commission. It is still unclear to whether or not the Edmonston B gave the Yanomami people the direct virus or that the people who were vaccinated with Edmonston B transferred the measles. Either way, the Yanomami population was devastated because of these manipulative anthropologists.
