I think its incredible that these Inca families are still showing continuity since before the Americas were "discovered". I also think its very important to study these groups of people, it is a good feeling when you know some history about your past and the people you come from. The colonization of the globe by europeans, really messed this up for people across the globe. Not only were the lives of these people ruined but it makes many feel like they don't fit in anywhere and do not know their family history. Of course the people of South America are not the only ones studies like this should continue around the world.
