History
In a recent podcast from The Naked Scientists, research has shown that people in the San Antonio de los Cobres area have remarkable developed a mutation in their genes to cope with the high levels of Arsenic in the area. Having concentrations about ten times higher that those deemed safe by the World Health Organization (WHO), naturally occurring Arsenic has created a very toxic environment in this region contaminating the water supplies. Evolutionary processes resulting from long term exposure have caused a specific mutation within the DNA of this population allowing them to process Arsenic more quickly throughout their systems and preventing the formation of poisonous byproducts that would normally form within the body with exposure to the element. This is the first adaptation in humans regarding a toxic chemical to ever be documented. http://www.thenakedscientists.com/HTML/podcasts/specials/show/20150312/
Economy
San Antonio de las Cobres takes its name from the nearby Sierra de Cobre, or Copper Mountain, which is rich in that mineral. Economic activity in the town is based on mining of the mineral-rich surrounding mountains, and weaving using local llama fibers. The town is also a stop along the Tren a las Nubes (Train of the Clouds), on the Salta-Antofagasta rail line.
