Ah, I see. You don't actually understand the differences between a race, culture, or ethnicity. Jere is a light overview:

1. Race is ONLY applicable to humans. It's just a social classification, not actually a scientific designation in any way shape or form.
2. Culture is a collective set of a group of people's customs, arts, achievements, traditions, etc.
3. Ethnicity is a quality of belonging to a group who share a culture.

Again, none of these are the same as being indigenous, even though there is a lot of cross over since indigenous peoples (in a specific area) usually are of one race, may share a common culture (or set of cultures), and arguably may be of the same ethnic group.
