Mitochondrial lineages in Iron Age Fennoscandinavia, comments

The distribution between lines U and H in Finland has been a point of discussion now.  Many thinkers have underlined that in a big view H is connected to Neolithic farmers and U to Mesolithic hunter gatherers.  Although it is interesting to combine different point of views, sometimes people forget the context and tend to overreact, as in this case has happened too.   Overall the transition to farming happened in Southern Europe around 7000-5000 BCE and in Northern Europe 3000-2000 BCE.  In light of this history all settlements in Finland are extremely young and in Southern Finland differences between female and male haplogroups manifest more migration routes from different compass points and different farmer populations, rather than introduction of Finnish agriculture.  Although I don't believe that this fact is totally missed, wrong highlighting can't be any good. Populations and migrations varied depending on time, during the latest 2000 years especially in the East Europe.   In my opinion in this point researchers have lost the substance, which would hold a question "where did they come and why so much later than in most other places in Europe".  The answer is to be discovered by comparing female and male haplogroups and types in Finland and in possible contact areas.
