In one recent study, scientists discovered coca leaf in between the teeth of a mummy. This actually suggests how she was killed.
One mother of a 15 – year old girl, who was frozen for 500 years, was found in 1999 in Argentina. Even though it has been concluded that this body of the girl was lifeless for five centuries, when she was found, her body was actually perfectly preserved. According to some foreign media, this girl was actually chosen as a sacrifice to the gods for some religious reasons.
There is one belief that in the early ages in Argentina, all the teenagers were taken to the high mountain tops, were they have been fed with coca leaves and upon reaching the burial site, the children were given an intoxicating drink.
In recent times, some scientists have discovered that this girl actually had a bacterial infection during the time she was sacrificed. They say that that kind of bacterial infection was similar to tuberculosis.
They also think that this discovery could potentially help in the treatment of some modern illnesses.
