Archaeologists have found 6000 -year -old skeletons from Colombia with ancient DNA that could rewrite the history of mankind.
The amazing remains belonging to the fisherman's college at the old Checua site of Checua do not have the DNA that matches any number of indigenous people known in the region today.

Their genetic signature revealed the bomb about distinct and extinct proportions.
This can descend along the way from the closest people to reach South America.
These proportions diverged early and remained isolated genetically for thousands of years.
The researchers managed to rebuild a rare genetic schedule by DNA of 21 people who lived in Bogotta Altbeliano between nearly 6000 to 500 years.
DNA samples extracted from bones and teeth showed that the oldest people in Checua carried a distinctive signature of ancestors.
This has completely disappeared from the modern gene Swimming pool.
“This field is the key to understanding how the Americans are suitable,” said Kim Louise Cretic, the main author and doctoral student at the Cenkkenberg Center for Human Development in Germany.
“The land bridge between North and South America and the meeting point for three major cultural areas: Central America, Amazon, and Andes Mountains.”
The first people were not associated with other old groups in South America genetically.
They also did not participate in the origins of the early North American residents.
“Our results showed that Checua personnel derive from the first population to spread and distinguish throughout South America very quickly,” Krettek added.
“We could not find the descendants of these first hunters of the Supreme Colombian plains, and the genes were not passed.
“This means in the area surrounding Bogota, there was a complete exchange of the population.”
About 2000 years ago, the genetic scene in the Bogota highlands turned.
The distinctive proportions discovered in the oldest remains of Checua were disappeared and replaced with new residents.
The DNA bear has a close similarity to the old Banmeans and the modern -speaking groups Costa Rica and Panama.
Participant author and researcher at the University of Nacional D. Colombia Andrea Kasas Vargas explained how the strange disappearance of the genetic effects of the indigenous population is rare in South America.
She said: “Until now, a strong genetic continuity has been observed in the residents of the Andes Mountains and the southern cone of South America for a long time Periods Cultural changes. “
As new arrivals reach the Bogota highlands, the population has changed dramatically over time.
But the shift did not come with any signs of war or invasion, nor violence, according to archaeologists.
The change may have occurred gradually through migration, cultural exchange, or mating.
Therefore, the unique DNA of the Checua people faded – and finally faded.
The incredible discovery is the first example Colombia Looking at the old DNA – but experts say it is just a beginning.
The surrounding areas such as West Colombia and Venezuela and Ecuador You did not receive genetic analysis.
Krettek said: “The old DNA from those areas will be decisive in understanding how humans migrated to South America.”
