A research published in the Proceedings of the National Academy of Sciences has shed light on the Inca practice of child sacrifice. The research, which was carried out by a group of researchers from University of Bradford, has found that children were sacrificed for a number of reasons.

Some of the many reasons for which children were sacrificed were at the times of war and natural disasters, on the important life milestone taking place in the lives of the Incas.

Study researchers have carried out tests on a teenage girl. After carrying out tests on her, it was unveiled that the girl was heavily sedated before she died.

Dr Emma Brown said that they have found mummified remains in 1999. After carrying out further study, it was revealed that three children were buried in a shrine that was discovered near the summit of Llullaillaco volcano in Argentina.

Among the three buried children, there was a 13 year old girl and remaining two were a younger boy and a girl. All three of them had consumed alcohol and cocoa leaves before their demise.

Dr Brown said that their analysis has unveiled that the manner of preservation of three remains is phenomenal.
