Reading treads I encountered very interesting problem : why there is no G2a in west Pirinei ? G2a is present in whole Europe , except in that region , east Baltic coast, central and northern Scandinavia .Lack of it in east Baltic coast , central and north Scandinavia can be explained by the fact that Neolitic farmers that use to carry G2a havent reached that regions , but that explanation is not god enough for west Pirinei. What is even stranger , that region is mountain , and G2a is elevated exactly in mountain regions : Apenini , Alps , Caucasus , ... Sometimes it is even described like haplogroup of goatbriders . Lack of G2a seems to corespond with spread of Basque ( in Spain and in France ) .
if someone can share some light on this mistery , please do .
