A major new article on the H Haplogroup was published in Nature Communications on April 23, 2013. The link is: ... s2656.html

The research examined 39 complete H Group sequences from skeletons of the early Neolithic to early Bronze age, and noted that there was a major shift of populations (H sub-clades) around 4,000 BC, with more major changes in the Bell Beaker Culture period, around 2,500 BC.

Abstract says:
Haplogroup H dominates present-day Western European mitochondrial DNA variability (>40%), yet was less common (~19%) among Early Neolithic farmers (~5450 BC) and virtually absent in Mesolithic hunter-gatherers. Here we investigate this major component of the maternal population history of modern Europeans and sequence 39 complete haplogroup H mitochondrial genomes from ancient human remains. We then compare this ‘real-time’ genetic data with cultural changes taking place between the Early Neolithic (~5450 BC) and Bronze Age (~2200 BC) in Central Europe. Our results reveal that the current diversity and distribution of haplogroup H were largely established by the Mid Neolithic (~4000 BC), but with substantial genetic contributions from subsequent pan-European cultures such as the Bell Beakers expanding out of Iberia in the Late Neolithic (~2800 BC). Dated haplogroup H genomes allow us to reconstruct the recent evolutionary history of haplogroup H and reveal a mutation rate 45% higher than current estimates for human mitochondria.

This is a massively important paper, with more than 20 authors. If you are ANY subgroup of Haplogroup H, you will want to track down the article. It is extremely meaty, and requires at least three readings to gain the full meaning of the results.
