For many years now, I have had a deep interest in the prehistory of this area of Europe and the origins of my own Celtic ancestors and of their language and culture. Over the last twenty years, this branch of learning has been the scene of deep controversies and certainties which have turned out to be completely wrong. Less than twenty years ago, the first DNA analyses of modern European populations were suggesting strongly that our ancestors were mostly of hunter-gatherer ancestry. The complexities of this debate no longer seem very important but suffice it to say that up until a few years ago, the overwhelming position was that there was little evidence that the gene pool of Europe had been greatly added to or changed since the Neolithic.
About four years ago, improved technology brought a bombshell. As it became easier and easier to test ancient remains, the experts started to get DNA from ancient Europeans, which showed that the gene pool of Ireland and Britain had undergone an almost total replacement at the beginning of the Bronze Age. There was a clear DNA trail from Ireland and Britain to Central Europe and from there back to the steppe and the transition to Indo-European language was no longer a mystery. The level of population replacement meant that only about 10% of the ancestry of Bronze Age British and Irish people derived from before the Beaker arrival.
Recently, I discovered a very detailed account of the origin of the Celts and their place within the Indo-Europeans in the light of these discoveries. It is on a site called Fortress of Lugh and is entitled: Are the Welsh and Irish Celts? The name Fortress of Lugh is a little odd and I have come across some criticisms of its author, Kevin MacLean, which suggest that he may be rather right-wing in some of his political attitudes. As anyone who has followed this blog will know, I am left-wing and liberal in my attitudes. I do not know if these criticisms of MacLean are justified. All I will say is that if he does have unpalatable political opinions (and I am by no means convinced that this is the case), he does an excellent job of keeping them out of his content. And then again, perhaps a right-winger who respects the facts is preferable to left-wingers who don’t (like most of Cassidy’s supporters).
Anyway, MacLean’s presentation on the Celts is superlatively well-researched, with an intelligent analysis and informed speculation. There is virtually nothing in it that I would take issue with and I cannot recommend it highly enough as a clear and cogent introduction to the new information which is coming to the fore in our knowledge of European prehistory.
