The majority of mexicans are indigenous
so called mexicans arent indigenous, they are first wave invaders that occupied the new world prior to the second wave involving european powers. The first wave were a mongoloid people, these are the progenitors of the midern day occupants of mexico.
The aboriginal population was dark skin, the mixture of blood would create the typical "indio". They are simply mongrelized mutts, no different from south east asians that have darker features compared to their eastern counterparts due to the admixture of the original inhabitants of the land (pic below). Spain would have a large genetic contribution as well creating a more pronounced population of mutts in the new world, though mexico seems the most dedicated to the concept of blanqueminto, to whiten up their population. The belief that they hold inheritance to the land is laughable, these people live a false identity and largley coopted a legacy that they had no relation to
