The researchers in Peru think they can follow the origins of the Incas, the greatest pre-Spanish civilization in America, through the DNA of their emperors' present-day grandchildren.
The Incas in the ancient capital Cusco controlled a vast empire called Tahuantinsuyo, which dates from present-day Argentina to the south of Colombia.
In the twentieth century, they ruled for more than 200 years before being conquered by the invading Spaniards.
The Empire, in present-day Peru, now includes the UNESCO World Heritage Site and the hilltop in Machu Picchu, a major tourist attraction.
Fascinated by Inca culture, organizational skills and engineering mastery, researchers Ricardo Fujita and Jose Sandoval began to take care of their genetic profile
(19459013) No Hierarchy in Pre-Income Community Living in Andlarda Impressive )
Researchers say that their purpose is to reveal whether they are a unique Inca patriot.
Fujita says, "It's like a paternity test among people, not between the father and the son."
Scientists want to confirm two common myths about the origin of the Incas. One of these myths, The Innocent is connected to a pair around Lake Titicaca in Peru's Puno district. The other is that the first Inchanges are defined as Pals from the village of Pacaritambo in the Cusco region. DNA samples were also taken from the remains of people who lived in these two places.
Fujita, "Three years after we followed the genetic fingerprints of the Grandson, we confirmed that two legends describing the origins of the Inca civilization could relate."
"More than 3,000 people were compared on a hereditary basis to reconstruct the genealogy of all the individuals."
"We eventually landed down to almost 200 people who share genetic similarities close to the Inca nobility."
Sandoval said, "The result we have is that two of the nobles of Tahuantinsuyo come from Lake Titicaca, the other on the Pacaritambo mountain in Cusco. This confirms the legends. "
But at the same time it shows that both myths are connected.
"Probably the first migration came from the Puno region and it was established in Pacaritambo for a few decades without going to Cusco and building Tahuantinsuyo."
But the researchers' work does not end here. Now they want to go back in time.
Therefore, to make the most complete picture of the origin of the most important pre-Hispanic civilizations, they have to test the DNA of ancient remains like mummies.
The task seems quite complicated because the Spanish invaders who arrived in 1532 destroyed the Incan mummies as they tried to convert their families into Christianity.
Researchers are now looking for where they buried to follow the history of the most direct descendants of the Incas.
DNA analyzes to be made will also contribute to archaeological and anthropological research to understand the true origins of humans.
