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 ...

The Y-DNA haplogroups contain R1 and other haplogroups found primarily in European regions. Similarly, the frequencies of Haplogroup J reach their highest levels across the Middle East region.
