This is also the case in many Afro-Asiatic languages. Celtic languages that used to be spoken in continental Europe had the verb in the final or middle position. Irish and British people have different proportions of blood types to most Europeans. Where there are comparable proportions is in the Atlas mountains in Northern Africa, home of the Berber people. Berber is a branch of the Afro-Asiatic language group.
Geneticists say there is no evidence of North African ancestors in Irish genes.
There is no good genetic evidence to support what the linguists are saying. You have to keep an open mind though. While in general clues about the identity of prehistoric inhabitants are gleaned from archeological remains and DNA, linguists say that certain elements of a language can preserve information about ancient times. It is widely known that when the Celts invaded Ireland there were people already here. Archeologists are not sure of the origins of prehistoric immigrants to Ireland.
