Their eye openings have beautifully sharp corners on each end as if cut by a scalpel.Lips are typically full and appear bright red against their white skin, even without makeup.The amino acid hydroxyproline (HYP), which accounts for 13% of the carbon in mammalian collagen, was targeted by the researchers.Dating this amino acid allows for the drastic improvement in the removal of modern contaminants from the specimens.
Diyendo Massiliani and colleagues reconstructed the complete mitochondrial genome of the specimen.
It falls within a group of modern human mt DNAs (haplogroup N) that is widespread in Eurasia today, confirming the view of some researchers that the cranium is indeed a modern human.
Further nuclear DNA work is underway to shed further light on the genetics of the cranium.'This enigmatic cranium has puzzled researchers for some time', said Professor Tom Higham, who leads the Palaeo Chron research group at the University of Oxford.
This theory appears true because Mongolian women have the most extreme manifestation of this trait.
It is not to say their eyes are squinty – some are quite open, but rather their eyes are subtly deeper set, resulting in a soulful gaze.
