Those data exist, and support an Iberian influence on the European
West Coast. I recently saw three book reviews in NATURE on precisely
that subject. One of them is "The Origin of the British - a genetic
detective story" by Stephen Oppenheimer, another by Richard Sykes who
has a name in genetics, I forgot the third one.

In my personal opinion the evidence for an Iberian colonization or
other strong cultural influence on Ireland is fairly convincing -
genetic, linguistic, and to some degree cultural. Of course we can
never really know, and I still take all this with a grain of salt, but
given that all the evidence in archaeology is circumstantial, this is
all we will ever get to make interpretations.

Sykes etc are talking about an entirely different time period, 6-10 KYA.

Possibly, I haven't seen Sykes, I just mentioned it. But I have some
figures from Oppenheimer which deal with younger migrations.

The only thing that worries me with these genetic studies that I do
not really understand how they arrive at their age data. I understand
isotopes, ok, but if a geneticist says, this gene developed x thousand
years ago, by which clock is that measured?

A lot of people have wondered.

AFAKI one basic assumption is, that the rate of mutation is the same, any
place, any time. If this was true, the number of mutations of a given
sequence, would allow a calcualation, of when this sequence first appeared.

Another basic assumption is, that the speed, with which a given mutation is
spread, is also a constant.

I see lots of problems with both assumptions.
