A new method of establishing hair and eye colour from modern forensic samples can also be used to identify details from ancient human remains, finds a new study published in BioMed Central's open access journal Investigative Genetics.

The HIrisPlex DNA analysis system was able to reconstruct hair and eye colour from teeth up to 800 years old, including the Polish General Wladyslaw Sikorski (1881 to 1943) confirming his blue eyes and blond hair.

A team of researchers from Poland and the Netherlands, who recently developed the HIrisPlex system for forensic analysis, have now shown that this system is sufficiently robust to successfully work on older and more degraded samples from human remains such as teeth and bones. The system looks at 24 DNA polymorphisms (naturally occurring variations) which can be used to predict eye and hair colour.

Dr Wojciech Branicki, from the Institute of and Jagielonian University, Kraków, who led this study together with Prof Manfred Kayser, from the Erasmus University Rotterdam, explained, "This system can be used to solve historical controversies where colour photographs or other records are missing. HIrisPlex was able to confirm that General Wladyslaw Sikorski, who died in a in 1943, had the blue eyes and blond hair present in portraits painted years after his death. Some of our samples were from unknown inmates of a prison. In these cases HIrisPlex helped to put physical features to the other ."

For medieval samples, where DNA is even more degraded, this system was still able to predict eye and hair colour (for the most degraded eye colour alone), identifying one mysterious woman buried in the crypt of the Benedictine Abbey in Tyniec near Kraków, sometime during the 12th-14th centuries, as having dark blond/brown hair and brown eyes.

It would be neat to find out how the hair and eyes of the neanderthals looked like. Also, were they more hairy (ape-like) than the modern human?

I realize that the above described method can not work with such old samples, but perhaps some day in the future it might..
