Step-by-step explanation:
The term 'mestizo' refers to 4) a person of mixed European and American Indian ancestry.
It originated during the time of the Spanish conquest of the Americas when Spanish men, who were largely soldiers and explorers, intermarried or had relationships with Native American women.
This led to the creation of a new ethnic group that combined the cultural and genetic heritage of both European Spaniards and indigenous peoples.
The mestizo population grew to become a significant part of the social fabric in Latin America, affecting social dynamics and creating a new cultural identity unique to the region.
