Brucie,

maybe that would have been a matter for PM, but perhaps someone else reading was interested as well.

I think I have it from Luigi Luca Cavalli-Sforza's book that I have read in German. The original Italian title was Geni, popoli e lingue which, if it has been translated into English may have been Genes, People, Languages.

He tells a lot about old migrations and how findings from linguistics and genetics (his own field) converge to tell a similar story about our past. Many things are still unclear, but the overall picture is much clearer than it was even ten years ago. I very much liked reading this book, but since I'm far from being an expert either in linguistics or in genetics I can't really tell how good it is.

Some bites about the Basques (my translation):
Let me point out that the region that most reliably represents the descendants of the first Europeans at the time of the arrivals of the Neolithians are the Basques....the Basques very probably descend directly from the Paleolithians who habitated the North of Spain and the Southwest of France....The Basque language has been spoken earlier in a much larger region than today....I deem it probable that the Basque language comes from the languages spoken by modern Cro-Magnon people when they first came to France and Spain.

He later cites linguistic results showing (perhaps better: claiming/interpreting) that the Basque language belongs to the sinodenekaukasian language superfamily that once was spoken nearly universally in Eurasia, but now is restricted to the Basques (only member of that family in Europe), to a language in the South of the Kaukasus and to Tibet and (parts of) China.
