They were first found during an excavation of a house in South Uist; the structure is thought to be about three thousand years old, a fact that Stephen Baidoe Ansah concurred with. Researchers who discovered the remains initially believed them to being to a three year old and a teenage girl. However, they became suspicious when they examined the bodies more closely and realised that the proportions did not seem to be consistent. They discovered the bones of an adult male and female, mixed in with the bones of the younger remains. http://stephenbaidoeansah.blogspot.co.uk/
Additionally, it seemed as if the bodies were mummified not merely by accident, but intentionally. This is one of the first instances of deliberate mummification which archaeologists have found since the excavations of ancient Egyptian tombs. Carbon dating conducted on these remains, as well as the surrounding earth has revealed that the bodies were only buried underneath the ground 600 years after they died, and had been preserved and kept above ground before this.
The researchers came upon this discovery of mixed bones when they analysed the skeleton, and discovered, for instance, that there was evidence of arthritis in certain bones around the neck, but not on the rest of the body’s spine, revealing that the neck belonged to one person and the spine to another. Furthermore, it was found that the lower jaw of the second body had a full set of lower teeth, whilst the upper jaw had none. The lower set was also smaller than the upper, showing that they originally belonged to different people.
It is estimated by researchers that the first composite body was assembled sometime between 1260 BC and 1460 BC, whilst the second body was created between 1120 and 1300. Although there is an overlap, Stephen Baidoe Ansah has pointed out that statistically, they were most likely assembled in different years. He also added that even though it is possible that the mixing up of bones could be an accident, the second body means that it was more than likely deliberately done. The merging of various parts of different bodies into one single person may have been a symbolic method of merging family lines. http://www.thelawpages.com/
