The Force is Strong With This One
The information about the genetic studies will be taken mainly from http://www.eupedia.com/europe/origins_haplogroups_europe.shtml, and its sub pages beside other sites which will be linked. Note that the genetic studies aren't taken as secure evidence, it's a young scientific branch, the interpretation varies between specific work and according specific result (which are not always 100% the same). I chose this site because averages the result of the studies. However, genetics can be good indication.
While your read this information and data, keep in mind the dates and geographical and historical (even celestal) events and locations which C's mentioned, and Laura wrote about and noted in the books. Generally you can find them here: http://cassiopaea.org/forum/index.php/topic,13982.0.html.
YBP - Year Before Present (universally considered before 1950).
Haplogroup - a population group who descended from a common ancestor, as evidenced by specific SNP mutations.
Clade/Branch - from the Greek word klados, meaning branch. A clade on the Y chromosome tree is also called a haplogroup.
Subclade/Subbranch - a term to describe the relationship between two clades with the subclade being downstream ie. sub-clades/branches of haplogroup.
Mitochondrial DNA (mtDNA) is inherited only through one's mother. As it does not recombine like chromosomes, it can be used in population genetics to trace back ancestry on the matrilineal side and to divide populations into haplogroups. In Europe, mtDNA haplogroups are quite evenly spread over the continent, and therefore cannot be associated easily with ancient ethnicities. This is generally explained because were send away to marry in another village or town, so that their lineages spread more evenly over time. This theory doesn't always abide with general historical events and the fact the males were the one who made raids and war – resulting with migrations.
According to the scholarship, since the time of the alleged Mitochondrial Eve, approximately 200,000 years ago (differs), modern humans have acquired in average 20 mtDNA mutations in each lineage - about one every ten thousand years. Even though the number of mutations has accelerated with the soaring of human population over the last 10,000 years, the dating of lineages based on mtDNA alone remains very approximate, and practically useless for historical times. However, mtDNA can sometime reveal some potential medical conditions.
For the extended (also in the geographical sense) basic knowledge on mtDNA see and research from https://en.wikipedia.org/wiki/Human_mitochondrial_DNA_haplogroup.
The Y-chromosome (Y-DNA) is inherited exclusively from father to son and does not recombine with the X chromosome. It is traced to the alleged Y-chromosomal Adam. Only a few mutations distinguish the Y chromosome of a man and his father. These mutations are cumulative from generation to generation, so it is easy to trace the family tree of humanity by analyzing these mutations (SNPs) on the Y chromosome and mtDNA.

I won't show images which depict Mesolithic Europe or Bronze Age Europe, because are heavly theorized on the contemporary historiography and archeology, while there's still serious lack of studies done on those ancient bodies which are dated to the respective time (even Middle Ages).

Now will mention the general distribution and pressumed initial age of origin of mtDNA haplogroups. From the link of "Haplogroup H" you can easly move on to other haplogroups, and read further information. Won't go into details and recent ages because for that need to know exact subclade, and the table does not show that (need to check individual studies).
All modern human mtDNA outside of Africa derive from the haplogroup L3, which is common in East Africa, but generally in other parts L1 and L2 represent 2/3 of mtDNA. It is more related to Eurasian haplogroups than divergent African clusters L1 and L2. From its (subclades) macro-haplogroups M and N the vast majority of non-Africans descend. It is dated between 80,000-104,000 or 60,000-70,000 YBP. It's relation with M and N is theorized as: "the lack of L3 lineages other than M and N in India and among non-African mitochondria in general suggests that the earliest migration(s) of modern humans already carried these two mtDNA ancestors, via a departure route over the Horn of Africa", "ancestral L3 lineages that gave rise to M and N have not been discovered outside Africa … lost by genetic drift". The N is by far the predominant haplogroup in Western Eurasia, and haplogroup M is absent in Western Eurasia, but is predominant in India and is common in regions East of India.
The M originate from c. 60,000-71,000 YBP, and is generally theorized from South Asia. The obvious South Asia origin of M is shown from being the most common mtDNA in Asia, it peaks in Japan and Tibet (70%), India and South Korea (60%), China (50-60%). Its subclades C and D exist in North Eurasia (Siberia) and Native American populations, E is observed in Southeast Asia, while Q in Melanesia.
The N originate from c. 71,000 YBP, and is generaly theorized from Asia, ie. between East Africa and Persian Gulf. Its subclades O (small group) exist in Australia-Oceania, A in East Asia (Eskimo, Tibetans) and Native Americans (Navajo, Apache), S (small group) in Australia, I in Eurasia (Iran, Western and Eastern Europe) and East Africa (few Kenya-Ethiopia tribes), W in Western Eurasia, X (small group) in Europe and Native Americans, Y (small group) in East Asia (Sea of Okhotsk). The subclade R is the most common in West Eurasia, and is dated c. 66,000 YBP. Its subclades are B, P, F, JT (pre-JT; sub J and T), R0 (HV; sub H and V), U (sub K).
Haplogroup H is the most common and most diverse maternal lineage in Europe, in most of the Near East and in the Caucasus region. The Saami of Lapland are the only ethnic group in Europe who have low percentages of haplogroup H, varying from 0% to 7%. The frequency of haplogroup H in Europe usually ranges between 40% and 50%. The lowest frequencies are observed in Cyprus (31%), Finland (36%), Iceland (38%) as well as Belarus, Ukraine, Romania and Hungary (all 39%). The only region where H exceeds 50% of the population are Asturias (54%) and Galicia (58%), in northern Spain, and Wales (60%). The mutation defining haplogroup H took place at least 25,000 years ago, and perhaps closer to 30,000 years ago. Its place of origin is unknown, but it was probably somewhere around the northeastern Mediterraean (Balkans, Anatolia or Levant), possibly even in Italy. Roostalu et al. (2006) estimate that H1 arose around 22,500 years ago.
HV is found at a frequency ranging from 4% to 9% in most of the Middle East. Its highest frequency is observed in Iraq and Kurdistan (9%), as well as among the Dargins (9%) of Dagestan, in the north-east Caucasus. HV is unevenly spread around Europe. Haplogroups HV0 and V are relatively evenly distributed across all Europe and North Africa, with a frequency ranging from 2% to 8% in practically all countries and regions. The only populations with substantially higher incidence of HV0 or V are the Saami (42%) of northern Scandinavia and Finland, and the Cantabrians (19%), isolated in mountains in northern Spain.
The mutation defining haplogroup HV0 is thought to have taken place around the Last Glacial Maxium (c. 19,000 to 26,000 years ago), while haplogroup V would have arisen in the Late Glacial period, some time between 16,000 and 12,000 years ago. The extremely high prevalence of haplogroup V among the Saami, who do not seem to possess any Near Eastern admixture, and maintained a hunter-gathering lifestyle throughout the ages, is the best proof that haplogroup V did not originate in the Near East but in Mesolithic Europe. The origin of haplogroup HV0 is less clear since HV is clearly Near Eastern. It is not possible to say at present whether HV0 developed in the Near East then moved into Europe during the Late Glacial period (Upper Paleolithic), or if it arrived to Europe as HV then became HV0 in Europe.
Haplogroup J is relatively evenly distributed across all Europe. The only population in which it is absent are the Saami from Lapland. The highest frequencies of mtDNA J in Europe are found in Cornwall (20%), Wales (15%), Iceland (14%), Denmark (13.5%), Sardinia (13%), Scotland (12.5%), England (11.5%), Switzerland (11.5%), the Netherlands (11%) and Romania (11%). In the Middle East, it is most common in Saudi Arabia (21%), followed by Kuwait (16%), Yemen (15%), Kurdistan (15%), south-west Iran (14%), Iraq (13%), and the United Arab Emirates (12%). The mutation defining haplogroup J is thought to have taken place some 45,000 years ago, probably in West Asia.
Haplogroup T is composed of two main branches T1 and T2. The two of them have very different distributions, which are diametrically opposed in most regions. Haplogroup T1 is not found among the Saami, the Jews, or the Avars of the Caucasus, and is extremely rare in Jordan, Morocco, northern Spain, Bosnia and Croatia. The highest frequencies of mtDNA T1 are observed among the Udmurts (15%) of the Volga-Ural region of Russia, followed by Romania (6%) and the southern Balkans (Bulgaria, Macedonia, Albania, all 4.5%), the northern Fertile Crescent (Lebanon, Iraq, eastern Turkey, all around 5.5%), the South Caucasus (Armenia, Georgia, Azerbaijan, 4.5% to 5.5%), then Austria and the Czech Republic (3.5%). Haplogroup T2 peaks among the Udmurts (24%) and the Chechen-Ingush of Daghestan (12.5%). After that T2 is most frequently encountered in the Netherlands (12%), Sardinia (10%), Iceland (10%), Switzerland (9.5%), Hungary (8.5%) and Ukraine (8.5%), as well as among many ethnic groups around the Caucasus such as the Kumyks (10%), Azeri (9.5%) and Georgians (9%). The mutation defining haplogroup T happened some time around 29,000 years ago, probably in the East Mediterranean region. T1 and T2 split from each others some 21,000 years ago, toward the end of the Last Glacial Maximum (c. 26,500 to 19,000 years before present).
Haplogroup U5 is found throughout Europe with an average frequency ranging from 5% to 12% in most regions. U5a is most common in north-east Europe and U5b in northern Spain. Nearly half of all Sami and one fifth of Finnish maternal lineages belong to U5. Other high frequencies are observed among the Mordovians (16%), the Chuvash (14.5%) and the Tatars (10.5%) in the Volga-Ural region of Russia, the Estonians (13%), the Lithuanians (11.5%) and the Latvians in the Baltic, the Dargins (13.5%), Avars (13%) and the Chechens (10%) in the Northeast Caucasus, the Basques (12%), the Cantabrians (11%) and the Catalans (10%) in northern Spain, the Bretons (10.5%) in France, the Sardinians (10%) in Italy, the Slovaks (11%), the Croatians (10.5%), the Poles (10%), the Czechs (10%), the Ukrainians (10%) and the Slavic Russians (10%). Overall, U5 is generally found in population with high percentages of Y-haplogroups I1, I2 and R1a, three lineages already found in Mesolithic Europeans. The age of haplogroup U5 is uncertain at present. It could have arisen as recently as 25,000 years ago, or as early was 50,000 years ago. In any case, U5 appeared to be the dominant maternal lineage among Paleolithic and Mesolithic European hunter-gatherers, until the arrival of farmers and herders during the Neolithic. Haplogroup U2 is rare lineage very homogeneously spread across most of Central Asia, Europe, the Middle East and North Africa, with a frequency typically ranging from 0.5% to 2%. Haplogroup U3 is primarily a Near Eastern and Caucasian lineage, being found only at a frequency exceeding 3% in the eastern Mediterranean and in the Caucasus. U3 is almost completely absent from Finland, Scandinavia, the Netherlands, Wales, and interestingly also Sardinia (despite the high level of Near Eastern ancestry among Sardinians).
In Europe, K is particularly common in Northwest Europe, with peaks observed in Belgium (14%), Ireland (12%), the Netherlands (10%), Iceland (10%), Denmark (9%) and France (8.5%). In the Eastern Mediterranean and the Middle East, haplogroup K reaches high frequencies in Cyprus (20%), among the Druzes of Lebanon (13%), in Georgia (12%), as well as among the Avars (13%) and the Dargins (12%) of Daghestan. Haplogroup K originated in West Asia as a subclade of haplogroup U8 some time between 20,000 and 38,000 years ago. Based on ancient DNA tests, haplogroup K appears to have been absent among the Western Hunter-Gatherers (WHG) who occupied western and central Europe before the Neolithic period.
Haplogroup I is a fairly rare haplogroup, being found in average in 2% of Europeans and under 1% of Near Easterners. Slightly more elevated concentrations are found in Daghestan, notably among the Dargins (6.5%), Chechens (6%) and Kumyks (5.5%), as well as in isolated parts of Europe such as Mordovia (6%), Latvia (4.5%), Lithuania (3%), Finland (4%), Brittany (3%), Great Britain (4%), Ireland (3%) and Iceland (4%), but also Serbia (3.5%), Croatia (3%), Bosnia-Herzegovina (3%) and parts of Italy. Haplogroups N1a and I have never been found in ancient samples from Paleolithic or Mesolithic Europe. N1a is thought to have originated in Southwest Asia.
Haplogroup W is particularly common in the eastern half of Europe, in the North Caucasus, in Central Asia, in Iran and in the north-west of the Indian subcontinent. In Europe, the maximum frequencies of W are observed in Finland (9.5%), Hungary (5%), Latvia (4%), Macedonia (4%) and Belarus (3.5%, but over 5% if we exclude the south). Haplogroup W is also well represented among some ethnicities of the North Caucasus, such as the Karachay-Balkars (8%), Avars (8%), Svans (8%) and Adyghe-Kabardin (5%). Haplogroup W is descended from haplogroup N2. It is defined by 11 new mutation thought to have arisen during the Late Glacial period, probably somewhere around the Caspian Sea some time between 16,000 and 20,000 years ago. The geographic distribution of haplogroup W suggests at a strong correlation with the historical population movements of Y-haplogroup R1a, the Balto-Slavic and Indo-Iranian branch of the Indo-European speakers.
Haplogroup X is one of rarest haplogroups in Europe, being found only in about 1% of the overall population. The highest incidence of haplogroup X is observed in Greece (4%), Macedonia (3%), Romania (2.5%) and around the Caucasus, notably among the Avars (5%), Adyghe-Kabardin (5%), Karachay-Balkars (4.5%), Nogays (4%), Dargins (3.5%), Armenians (3.5%), Azeri (3.5%). The only Eurasian ethnic group possessing a relatively high percentage of haplogroup X are the Druzes of Lebanon, Syria and Israel, among whom X makes up 15% of maternal lineages. The X2a subclade is also found among many indigenous Amerindian people from North America, notably among the Sioux (15%), the Nuu-Chah-Nulth (11%–13%), the Navajo (7%), and the Yakama (5%). The mutation defining haplogroup X is thought to have taken place during the late Upper Paleolithic, some time between 20,000 and 35,000 years ago, probably in West Asia. Haplogroup X has never been found among Mesolithic hunter-gatherers from Europe or North Africa.
The Y haplogroup will be analyzed separately in more details in the next post because it can be more easly compared with migrations and specific cultures.

The highest incidence of haplogroup X is observed in Greece (4%), Macedonia (3%), Romania (2.5%) and around the Caucasus, notably among the Avars (5%), Adyghe-Kabardin (5%), Karachay-Balkars (4.5%), Nogays (4%), Dargins (3.5%), Armenians (3.5%), Azeri (3.5%). The only Eurasian ethnic group possessing a relatively high percentage of haplogroup X are the Druzes of Lebanon, Syria and Israel, among whom X makes up 15% of maternal lineages. The X2a subclade is also found among many indigenous Amerindian people from North America, notably among the Sioux (15%), the Nuu-Chah-Nulth (11%–13%), the Navajo (7%), and the Yakama (5%). The mutation defining haplogroup X is thought to have taken place during the late Upper Paleolithic, some time between 20,000 and 35,000 years ago, probably in West Asia. Haplogroup X has never been found among Mesolithic hunter-gatherers from Europe or North Africa.
The Y haplogroup will be analyzed separately in more details in the next post because it can be more easly compared with migrations and specific cultures.
