A sense of identity

There are some news items which carry with them an almost automatic sense of identification, much like the feeling when your local community is even mentioned in a national story. In this case that feeling, as a one-time readhead (but never a 'ginger') is even more potent.

Neanderthals 'were flame-haired'
Some Neanderthals were probably redheads, a DNA study has shown.

Writing in Science journal, a team of researchers extracted DNA from remains of two Neanderthals and retrieved part of an important gene called MC1R.

In modern people, a change - or mutation - in this gene causes red hair, but, until now, no one knew what hair colour our extinct relatives had.

By analysing a version of the gene in Neanderthals, scientists found that they also have sported fiery locks.

"We found a variant of MC1R in Neanderthals which is not present in modern humans, but which causes an effect on the hair similar to that seen in modern redheads," said lead author Carles Lalueza-Fox, assistant professor in genetics at the University of Barcelona.
