Neanderthals, extinct cousins of modern humans, occupied Western Eurasia before disappearing and although it was once thought that they traveled as far east as Uzbekistan, in recent years an international research team with the participation of the University of Valencia discovered that they reached two thousand kilometers further East, to the Altai Mountains of Siberia. An international research team led by Domingo Carlos Salazar, CIDEGENT researcher of excellence at the University of Valencia, published today in the Journal of Human Evolution the first attempt to document the diet of a Neanderthal through a unique combination of stable isotope analysis and identification of plant micro-remnants in an individual.
