What do you think of red hair being a trait supposedly originating in Neanderthalsâthat's what's being shown [they say] from the genome the Max Planck Institute has just recently sequenced. Another thing being bandied about at this relatively early juncture is that Neanderthals were a matriarchal society, with women ruling the roost (read, "fiery redhead"!)
The type of melanin responsible for red hair is actually a different chemical compound, pheomelanin, that requires a different gene for expression.
Answer
This could explained how those tall, broad-shouldered, red-haired Vikings were able to survive & do so much invading and pillaging, plus leaving many local women pregnant after long sea voyagers in open boats across the frigid north seas.
The present Scandinavian people would have less Neanderthal blood now due to the diluting gene-pool factor from the captive foreign women interbreeding with them.

Do you believe that the red hair gene comes from Neanderthals?
Q. A study was conducted in the U.K. in 2001 which determined that the gene that causes red hair + freckles in people is a very old gene (dating 50,000 - 100,000 years).
Modern man (Cro-Magnons) didn't come about until approximately 40,000 years ago, so it is believed that the red hair gene comes from Neanderthals. What are your thoughts on this?
I think it's possible, especially because Neanderthals lived in a very cold environment (Ice Age Europe). Red heads are pale, and pale skin is associated with cold environments. I could easily picture Neanderthals being pale and having red hair.

Answer
no serious scientist could say, that modern humans and neanderthals never intermixed. They could only say, that surveys, this far, have no evidence for such an occurence. but as they were conducted on a very tiny bit of the dna (mtDNA, most notoriouisly) this surveys have no wight for this kind of assumption. they are nothing more than a hint so far. as you are reading this, some scientist are sequencing the genome of the neanderthal. (they hope have the whole genome by 2008).if they succeed and the validity of their research is confirmed, we will be able to shed some more light on the question of intermixing of these two human kinds. but we will haave to bear in mind, that we are comparing with the genome of only one individual of the neanderthals.
the medias tend to simplify the facts to the points to present them in a false light. we can not reject the hypothesis of the neanderthals and modern humans intermixing today.
As far as i remember, the assumption, that this red hair-gene (it's called ginger-gene, i think). is a "gift" from our neanderthal cousins is far fetched and merely based on a synchronicity. with the help of a so called molecular clock, the scientist tracked back the age of this gene to an age, when neanderthals were still around and concluded, that it must have come from that from this fact. That's all. Methodically that's very weak. modern humans did also exist at that time, so it could be inherent of the modern humans too. today, it is most parsimonious explanation and thus the most probable. however, as stated above, intermixing can't be refuted. If we do not, by chance, find the ginger-gene in the neanderhtal-genome, we may never know if it came from the neanderthals or not.
