If the passage you are referring to is: "Dia de los Muertos - or "Day of the Dead" - is celebration held by Mexicans, Mexican Americans, and many who live in the Southwestern United States. Observed every November 2, the holiday occurs at the same time as "All Saints' Day," which is observed by Roman Catholics. It also incorporates many beliefs that pre-date European arrival in the Americas, such as honoring one's ancestors." 

you could conclude based on the passage above that Latin American cultures have blended together over time. Religiously and traditional cultures have mixed and have been a big influence and made it a part of the culture of the Latin American.
