The question could be "What did the Yaqui tribe need?
If that is the case, the correct answer is "Yaqui needed the cooperation of the museums."
After some tense negotiations, the Mexican government could have the support of New York's American Museum of Natural History (AMNH) and finally could have the bones. These bones were given back to the Yaqui tribe members because Native Mexican tribes are very respected in Mexico. So instead of putting them in a museum's exhibition, the government gave it back to the Yaquis because it understood the religious customs, culture, and traditions of this tribe.
Yaqui people live in the North region of the state of Sonora (border state to Arizona, US). They have a series of religious traditions and ceremonies and the tribe considered correct to bury the bones to give peace to the souls of those Yaquis.
