The ritual of decapitation among the autochthonous Americans has a recollective and deep history . Historical evidence for this practice has been found across both North and South Continent . And until now , the oldest reports were from archeological remains discovered in the Peruvian Andes , which escort to around 3,000 eld ago . Buta unexampled discoveryfrom Brazil now push the date back for the first known ritualized beheading of humans in the Americas by an incredible 6,000 year .

From shrunken heads made celebrated by the Jivaros in Ecuador , to the grisly practice session perform by the Munduruku Indians from northerly Brazil who would remove all flaccid tissue paper and then fume the remains and advert up the solvent , head - hunt was common among indigenous American communities . Even though some have suggest that trophy hunt was in fact a resultant of the requirement from European markets for the macabre keepsake , evidence seems to substantiate that head - hunting was dominant before European colonizers arrived . But how long ago did this ritual showtime ?

While excavating a rock shelter in east - central Brazil , the investigator of a new study   published inPloS Onefound something unexpected . Called Lapa do Santo , the rock music shelters are recognize to have been used by some of the earliest experience dweller of South America . “ They were   hunter - gathers or forager who lived in the area for at least 12,000 years , ”   explained Rodrigo Elias Oliveira , one of the coauthors of the study , in an electronic mail to IFLScience . In the protection , a total of 37   burials have been unearthed , but it was the 26ththat was   of most interestingness .

“ sepulture 26 ” was found in a circular grave roughly 40 centimeter ( 16 inches ) in diameter , and dwell of just the decapitated skull of an individual , with properly and get out severed hands covering the face . The researchers   from the Max Planck Institute   were able to find v - shaped cuts made into the vertebrae at the alkali of the skull , suggesting that the skull was forcibly removed from the body . In addition to this , marker on the jaw of the skull indicate that soft tissue was also removed .

Comparing the remain’sisotopicsignature to other burials found at Lapa do Santo , it seems that the individual   who met his or her sick closing 9,000 years ago was likely a local extremity of the group . All this grounds , the researchers take , suggests that this is the early ritualized decapitation of humans in the New World .   “ The implication of this find is a big change in the thought that beheading was an Andean phenomenon , ” says   Oliveira . If they are prove right , then it could lead to an overhaul of former theory about the origins of this exercise , and how it spread amongst endemic groups .
