I am a descendant of Katrine (sometimes I find it is spelled Katrina) (K2a7). What an awesome time we live in…. to be able to find onesself in the vastness of humanity dating back to the stone age. Unvelievable, and thank you wikipedia. I cant wait to add to this post. And a toast to my ancient grandmother Eve, or mt-Eve or mt-MRCA, as the historical beginning of us all, again, thank you wikipedia.
K2a7 : found in France and Britain
Uncle Otzi : the iceman (“hypervariable segment (HVS-I). Two nucleotide transitions, at positions 16224 and 16311, indicate that Ötzi’s mtDNA belonged to haplogroup K, (but K1 apparently not K2 like me) a subclade of the major west Eurasian haplogroup U”)….
It would behoove us all to examine our expansive backgrounds and unity in ancestry, there are no walls, no borders, no exclusions… we are a collective humanity. The dots on the map for my ancestors is enormous…. “I might be a lot like stone soup….. a little piece of this and that, from here and there, contributed by countless these and those”
“Haplogroup K originated in West Asia as a subclade of haplogroup U8b some time between 20,000 and 38,000 years ago……It is now certain that haplogroup K was a major maternal lineage of Neolithic farmers and herders before they entered Europe.”
This reference provides a long table of K origins, including this below which includes K2a7. (14,000 – 7,000 years ago; Behar, et al.)
K2
K2a : found in Late Neolithic England (Bell Beaker) and in Bronze Age Poland
K2a1 : found in Britain / found in EBA England
K2a2 : major Ashkenazi Jewish subclade
K2a3 : found in northern and eastern Europe
K2a4 : found in northern Europe
K2a5 : found in north-western Europe and Iran (Persians) / found in Bronze Age France and Russia (Fatyanovo culture)
K2a6 : found in the North Caucasus, central and north-western Europe
K2a7 : found in France and Britain
K2a8 : found in Spain and the Canaries
K2a9 : found in Neolithic Alsace
K2a10 : found in north-western Europe
Wikipedia states “A study involving Caucasian patients showed that individuals classified as haplogroup J or K demonstrated a significant decrease in risk of Parkinson’s disease versus individuals carrying the most common haplogroup, H”
L(mtDNA Eve)-N-R-U-K
Haplogroup K, formerly Haplogroup UK, is a human mitochondrial DNA (mtDNA) haplogroup. It is defined by the HVR1 mutations 16224C and 16311C. It is now known that K is a subclade of U8.
