Thanks for the information, I was not aware they could break it down like this.
U5: The mitochondrial super-haplogroup U encompasses haplogroups U1-U7 and haplogroup K. Haplogroup U5, with its own multiple lineages nested within, is the oldest European-specific haplogroup, and its origin dates to approximately 50,000 years ago. Most likely arising in the Near East, and spreading into Europe in a very early expansion, the presence of haplogroup U5 in Europe pre-dates the expansion of agriculture in Europe. Haplogroup U5a1—a lineage within haplogroup U5—arose in Europe approximately 30,000 years ago, and is mainly found in northwest Europe. In the context of its rather ancient origin, the modern distribution of haplogroup U5a1 suggests that individuals bearing this haplogroup were part the initial expansion tracking the retreat of ice sheets from Europe. Bryan Sykes in his Seven Daughters of Eve book named this mtDNA haplogroup Ursula.
