Tutankhamen's filiation remains subject to debate, as is the case for several Egyptian sovereigns. In the Journal of the American Medical Association of 17th February 2010, Zahi Hawass, the very media savvy head of the Supreme Council of Egyptian Antiquities, revealed the results of a DNA analysis carried out on a dozen or so mummies from the New Empire period, including that of Tutankhamen. According to this study, the 'child king,' who died at the age of 19, was the fruit of an incestuous union between his father, Akhenaton, and one of his sisters. His mother was thus also his aunt, and thus not queen Nefertiti. Dimitri Laboury's book, brought to completion before this announcement, does not raise the subject. Questioned on the point the author, whilst stressing the importance of this new research, emphasises the fact that it is necessary to be remain very prudent concerning DNA analyses of ancient times, because it is a question of material which is highly contaminable and corruptible. Over the course of the millennia which have followed their burial, the royal mummies of the New Empire have been regularly moved and intermingled. They could thus have been in contact with the DNA of other mummies, without taking into account the risks of contamination by modern DNA. It is thus that a DNA analysis carried out on a series of human mummies and that of a dog, who there is no doubt whatsoever lived at different times, spread over a period of 150 years, led to the conclusion that they were all brothers and sisters. Even the dog… If it is true that incest was not at all exceptional in the Egypt of Antiquity, it is thus still difficult to establish the absolute certain proof of it in this particular case. The innovatory research carried out by Z. Hawass' team thus opens up new perspectives, which is without doubt necessary to extend by other supplementary samples.
