Not only people were suspected to have immigrated to Machu Picchu, there were several animal bones found that were not native to the site. Most animal bones found were from llamas and alpacas. These animals naturally live in altitudes of 14000 ft above sea level rather than the mere 8000 ft Machu Picchu rests on.
