CAIRO, Egypt – Egyptian scientists are carrying out DNA tests on two mummified fetuses found in the tomb of King Tutankhamun to determine whether they are the young pharaoh's offspring, the antiquities authority said Wednesday.
The two tiny female fetuses, between five to seven months in gestational age, were found in King Tut's tomb in Luxor when it was discovered in 1922.
DNA samples from the fetuses "will be compared to each other, along with those of the mummy of King Tutankhamun," the head of the Supreme Council of Antiquities, Zahi Hawass, said in a statement.
The testing is part of a wider program to check the DNA of hundreds of mummies to determine their identities and family relations.
Hawass said the program could help determine Tutankhamun's family lineage, which has long been a source of mystery among Egyptologists.
The identity of Tut's parents is not firmly known. Many experts believe he is the son of Akhenaten, the 18th Dynasty pharaoh who tried to introduce monotheism to ancient Egypt, and one of Akhenaten's queens, Kiya.
But others have suggested he was the son of a lesser known pharaoh who followed Akhenaten.
Scholars believe that at age 12, Tutankhamun married Ankhesenamun — a daughter of Akhenaten by his better known wife Nefertiti — but the couple had no surviving children.
There has been no archaeological evidence that Tut, who died around the age of 19 under mysterious circumstances over 3,000 years ago, left any offspring.
Tutankhamun was one of the last kings of Egypt's 18th Dynasty and ruled during a crucial, turmoil-filled period when Akhenaten's monotheism was ended and powers were returned to the priests of ancient Egypt's multiple deities.
The council said that if the tiny mummies are unrelated to Tut, they may have been placed in his tomb to allow him to "live as a newborn in the afterlife."
Ashraf Selim, a radiologist and member of the Egyptian team, said the tests could take several months. So far, the team has carried out CT scans on the two fetuses and taken samples for DNA tests.
"We want to find out the truth and facts relevant to the history of these kings," Selim told The Associated Press.
Since they were found in King Tut's tomb, the mummified fetuses were kept in storage at the Cairo School of Medicine and were never publicly displayed or studied, Selim said.
Hawass has announced ambitious plans for DNA tests on Egyptian mummies, including tests on all royal mummies and the nearly two dozen unidentified ones stored in the Egyptian Museum in Cairo.
He has said the tests may show that some royal mummies on display are not who archaeologists thought them to be.
One of his top goals is to find the mummy of Nefertiti, the queen legendary for her beauty.
Last year, Egypt announced that archaeologists had identified the mummy of Hatshepsut, Egypt's most powerful queen and the only female pharaoh. But scientists later said they were still analyzing DNA from the bald, 3,500-year-old mummy to try to back up the claim.
There is some secrecy surrounding Egypt's DNA testing of mummies.
Hawass has long rejected such testing by foreign experts, and only recently allowed it on condition the tests be done exclusively by Egyptians.
A $5 million DNA lab was created at the Egyptian Museum, with funding from the Discovery Channel.
Some experts have warned that Hawass is making claims like that of Hatshepsut too quickly, without submitting samples to a second lab to corroborate DNA tests or publishing the results in peer-reviewed journals, both common practice.
The council announced in its statement Wednesday that the government had agreed with Cairo University's Faculty of Medicine to open a second DNA testing lab, though it did not give details on funding for the lab or when it could begin work.
Abdel-Halim Nour el-Deen, a former head of the council and a leading Egyptologist said DNA testing on mummies thousands of years old is very difficult.
"It is doubtful that it could produce a scientific result to determine such important issues such as the lineage of pharaohs," Nour el-Deen told the AP.
Nour el-Deen also criticized the antiquities authority for not making public the results of the tests already carried out.
