Final answer:
The inter-marriage and mixing of cultures can be traced back to the movement of people, the spread of cultures, and technological innovations. In the sixteenth century, the interaction among Europeans, Native Americans, and Africans in cities led to transculturation, resulting in inter-cultural interactions and inter-marriages.
Step-by-step explanation:
The mixing of cultures and inter-marriage can be attributed to various factors such as the movement of people, the spread of cultures, and technological innovations of diverse groups.
One example of this is the interaction among Europeans, Native Americans, and Africans in the sixteenth century, which led to transculturation. In cities, where different ethnicities lived closer together, inter-cultural interactions were more common, leading to the inter-marriage and mixing of cultures.
For instance, on plantations in Spanish America and Brazil, African slaves and indigenous peoples worked alongside mestizos, resulting in cultural blending.
