The team also found the grave of another infant near that of the twin boys. This was no surprise, as in ancient societies the morality rate among newborns was very high. The child was determined to have died at about three months old and it was once swaddled by a cloth that was probably tied together with a pin. The Daily Mail quotes the researchers as saying that “the third infant who had been deposited in the second grave turned out to be their third-degree relative.” In other words, the baby found in the single grave was the cousin of the twins.
