I've deleted this recently added text because no supporting evidence was provided. See Wikipedia:No original research. Until hard evidence (DNA from ancient remains) is found, it's premature and speculative to draw these links between haplogroups and ancient migrations.Agiseb (talk) 22:50, 31 July 2010 (UTC)
- Principally a European haplogroup, haplogroup I is detected at very low frequency across west Eurasia with slightly greater representation in northern and western Europe. Given its wide, but sparse, distribution, (2.37%) it is likely that it was present in those populations that first colonized Europe. This hypothesis is supported by the estimate its age—approximately 30,000 years.
- I individuals descend from a woman in the N branch of the tree. This woman was the common ancestor of what can be described as a western Eurasian lineage, the descendants of whom live in high frequencies in northern Europe and northern Eurasia. Descendants from this western Eurasian lineage used the Near East as a "home base" of sorts, radiating from that region to populate much of the rest of the world. Today, members in the Near East belonging to haplogroup I have more divergent lineages than those found in northern Europe, indicating a greater time in the Near East for those lineages to accumulate mutations.
- Therefore, early members of this haplogroup likely moved north across the Caucasus, their lineages being carried into Europe for the first time during the middle Upper Paleolithic. This wave of migration into western Europe marked the appearance and spread of what archaeologists call the Aurignacian culture. The culture is distinguished by significant innovations in methods of manufacturing tools, standardization of tools, and a broader set of tool types, such as end-scrapers for preparing animal skins and tools for woodworking.
- In addition to stone, the first modern humans to reach Europe used bone, ivory, antler, and shells as part of their tool kit. Bracelets and pendants made of shells, teeth, ivory, and carved bone appear at many sites. Jewelry, often an indication of status, suggests a more complex social organization was beginning to develop.
- Today, only about ten percent of the mitochondrial lineages found in Europe reflect the original early Upper Paleolithic movements into the continent, and about 20 percent reflect the more recent Neolithic movements. The rest of the European mtDNA, including haplogroup I, are the result of migrations into Europe during the middle Upper Paleolithic around 25,000 years ago. These took part in the post-glacial re-expansions around 15,000 years ago as the ice sheets receded during the late Upper Paleolithic.
what constitutes central Europe?
Slovakia, Poland, and Hungary (among other nations or parts of nations) are in Central Europe. And so, with the ethnic group with the highest percentage of mtDNA Hg I being the Lemkos in SE Poland, eastern Slovakia, extreme SW Ukraine, and NE Hungary... how can the author of this article (or the reference cited therein) state that I is not found in Central European populations?
During the Cold War, this part of Europe was often thought of as Eastern Europe. It made things easier. West vs. East. Us vs. them. 'Free' states and Soviet-controlled states. However, geographically, Slovakia is in Central Europe. Kosice and Bratislava are closer to Paris than they are to Moscow. Eastern Europe is most of Russia, eastern Ukraine, European nations in the Caucasus, Moldova, etc. Hungary and Slovakia and southern Poland are basically in the very heart of Europe, both based on culture and latitude and longitude. Lemkos are Central Europeans. — Preceding unsigned comment added by 220.127.116.11 (talk) 01:59, 15 February 2012 (UTC)
