Genetic analysis of individuals swallow in sepulchral monuments near a vent in southern Peru have unwrap the crime syndicate relationships and burial traditions of ancient Peruvian that inhabit before Christopher Columbus sail to the Americas .
Theancient Peruviansburied their dead in " chullpas , " structures resembling erect tomb , which can be up to 6.5 feet ( 2 meters ) high . researcher had n’t known how the individuals immerse within one chullpa were touch .
Ancient chullpas, or funeral towers, are yeilding insights into ancient peruvian famlies.
family were organise into " ayllu , " a group of relatives that shared common acres and province . historian think that men retained the ancestral land , and they trade in their sisters for wife , in a sort of " sis exchange . "
Ancient genes
In the new subject , researchers from the University of Warsaw , in quislingism with Universidad Catolica de Santa Maria , retrieved and analyze genomic successiveness of 41 individual buried in six chullpas located 13,000 feet ( 4,000 meters ) up the side of the Cora Cora Mountainin southern Peru . Though the site had been looted , the remains were well continue by the cold and the sobriety of the kingdom , and the researchers were able to isolate DNA from the bones and teeth of 27 somebody . [ Top 10 Weird Ways We shell out With the Dead ]
Researchers collected bone and teeth samples to analyze the ancient Peruvian’s genes.
They looked at the atomic DNA , which is our master genetic codification and is inherit from both parents , along with the motherly inherited mitochondrial genome ( which is separate from the nuclear genome , and pass the cellular telephone ’s energy manufactory , the mitochondria ) ; they also analyzed genetic sequences from the Y chromosome , which is inherit from the father and determines that an somebody is male .
They used this information to describe the sex of each individual and equate their genes so as to figure out the category relationship between them . They also compared their DNA with a sampling of 700 individuals from contemporary Amerindian populations from South America .
The researchers found that the the great unwashed from the chullpas were genetically interchangeable to modernAndean populationsfrom Peruvian neighborhood like Puno , San Martin , Ancash and Yungay . European colonisation of the area did n’t seem to have an wallop on the genetics of the hoi polloi live in the region .
family line connexion
The investigator also found that the crime syndicate connectedness between individuals were the strong within each chullpa , and most likely a given ayllu buried its members in
one chullpa for many generations .
Two of the chullpas contained set of males with very Y chromosomes , which meant these were two groups of directly related males ( fathers , sons , brothers ) of several generation inhume together . This finding mate the presently accepted male - command ayllu hypothesis .
There was an outlier , though . In a third chullpathree different male lineageswere found . compare of the parental deoxyribonucleic acid of these males suggests that two of the male had the same female parent but unlike fathers , and the third male person was relate to one of the mother ( but not the fathers ) , probably a half buddy .
The investigator explicate this oddity in their newspaper publisher , issue online April 23 in the journal BMC Genetics , by saying that " the rules govern marriage and societal organization were an idealization , and we can not exclude a situation that was on purpose or unintentionally violated in some situations .
