IBERIANS.
The Iberians developed a surprisingly sophisticated culture in the Mediterranean coast of the Iberian Peninsula from the 6th century BC until their conquest by the Romans in the 2nd century BC. They spoke and wrote a non-Indo-European language that still cannot be understood; their origins and relationships with other non-Indo-European peoples, like the Etruscans, are unclear, since their funerary practices were based on the cremation of bodies, and therefore anthropology has been unable to approach the study of this people. We have retrieved mitochondrial DNA (mtDNA) from a few of the scarce skeletal remains that have been preserved, some of them belonging to ritualistically executed individuals. The most stringent authentication criteria proposed for ancient DNA, such as independent replication, amino-acid analysis, quantitation of template molecules, multiple extractions and cloning of PCR products, have been followed to obtain reliable sequences from the mtDNA hypervariable region 1 (HVR1), as well as some haplogroup diagnostic SNPs. Phylogeographic analyses show that the haplogroup composition of the ancient Iberians was very similar to that found in modern Iberian Peninsula populations, suggesting a long-term genetic continuity since pre-Roman times. Nonetheless, there is less genetic diversity in the ancient Iberians than is found among modern populations, a fact that could reflect the small population size at the origin of the population sampled, and the heterogenic tribal structure of the Iberian society. Moreover, the Iberians were not especially closely related to the Etruscans, which points to considerable genetic heterogeneity in Pre-Roman Western Europe.
The most frequent haplogroup is H (52.9%), followed by U (17.6%), J (11.8%), and pre-HV, K and T at the same frequency (5.9%). No samples were found to correspond to other haplogroups that are widely present in the Iberian peninsula populations (Table 7), such as V, X, I or W. The North African U6 subhaplogroup and Sub-Saharan African L lineages are also absent from the ancient Iberians analyzed so far; therefore, the possible entry of U6 lineages prior to the Muslim conquest in the 8th century A.D., as suggested by some authors, remains unproven. However, it is recognized that the sample size is at present too small to exclude any competing hypothesis about a possible North African genetic contribution to the genesis of the Iberian peninsula populations.
For the study, mitochondrial DNA was extracted from skeletal remains of individuals, some of them ritually executed. The most frequent haplogroups are:
H (52.9%)
U (17.6%)
J (11.8%)
pre-HV (5.9%)
K (5.9%)
T (5.9%)
It is shown that the composition of the ancient Iberian haplogroup is very similar to the current mainland population (although there is a lower genetic diversity in ancient remains.) However, no currently haplogroups found widely spread throughout the Iberian peninsula as V, X, I or W.
About the U6 found in Galicia.
Sequencing of 81 entire human mitochondrial DNAs (mtDNAs) belonging to haplogroups M1 and U6 reveals that these predominantly North African clades arose in southwestern Asia and moved together to Africa about 40,000 to 45,000 years ago. Their arrival temporally overlaps with the event that led to the peopling of Europe by modern humans and was most likely the result of the same change in climate conditions that allowed humans to enter the Levant, opening the way to the colonization of both Europe and North Africa. Thus, the early Upper Palaeolithic population carrying M1 and U6 did not return to Africa along the southern coastal route of the "out of Africa" exit, but from the Mediterranean area; and the North African Dabban and European Aurignacian industries derived from a common Levantine source.
