Mexican photographer Diego Huerta has spent the past four years on a quest to photograph all of the indigenous groups in the country. He publishes select images on his website and on his instagram account and the collection of images makes for compelling viewing, hence articles about him in the press, including one entitled “Photographer Captures The Breathtaking Beauty Of Mexico’s Indigenous Communities” in the Huffington Post.
For an introduction to Mexico’s indigenous peoples see An overview of Mexico’s indigenous peoples. Recent research has shown that the indigenous groups are more genetically diverse than was previously thought. They add a very significant diversity to the languages spoken in Mexico. See, for example, The geography of languages in Mexico: Spanish and 62 indigenous languages, and Is the number of speakers of indigenous languages in Mexico increasing? The many indigenous languages have resulted in some very distinctive place names.
At least one of the indigenous languages in Mexico is very unusual – Whistling your way from A to B: the whistled language of the Chinantec people in Oaxaca – and some have no words for “left” or “right”, while others are now spoken by only a very small number of people. The extreme example of this is Only two native speakers remain of Ayapaneco, an indigenous language in Tabasco.
