Context:

  • Researchers in Peru believe they have traced the origins of the Incas — the largest pre-Hispanic civilisation in the Americas — through the DNA of the modern-day descendants of their emperors.

Background:

  • From their ancient capital Cusco, the Incas controlled a vast empire called Tahuantinsuyo, which extended from the west of present-day Argentina to the south of Colombia.
  • They ruled for more than two hundred years before being conquered by the invading Spanish in the 16th century. The empire included the mountain-top citadel of Machu Picchu in modern-day Peru — now a UNESCO World Heritage Site and a major tourist attraction.
  • Probably the first migration came from the Puno region and was established in Pacaritambo for a few decades before heading to Cusco and founding Tahuantinsuyo.
