Paternal Ancient Ancestry Haplogroup R1b first arrived in Europe from West Asia during the Upper Paleolithic period (35,000-40,000 years ago) at the beginning of the Aurignacian culture. This culture is one of the first within Europe to leave cave art, and their stone tools were more refined than previous periods. The Périgordian culture is also thought by some to have existed at this time.
As the last ice age began, it became necessary to move down to below the tree line to hunt game. At its peak, the ice shelf within Europe extended down as far as southern Ireland, the middle of England and across northern Germany. Scandinavia was entirely covered. The sea ice pack extended as far as northern Spain, and tundra covered much of continental Europe. The tree line at the height of the ice age extended as far south as southern France, northern Italy, the northern Balkans and across the Black Sea.
People with Haplogroup R1 Y-chromosomes retreated to below these regions where they established themselves. As the ice age ended and the fauna and flora were able to move northward again, people in R1b also migrated north. Haplogroup R1 appears in about 50% of the total European population whereas R1b remains by far the most common haplogroup in western Europe (Spain, Portugal, France, UK and Ireland). R1b3, one of the most successful clades, has its origins about 11,800 years ago. Within the British Isles, a genetic pattern called the Atlantic Modal Haplotype (AMH) features greatly among the Irish and Welsh. Some researchers consider this haplotype to be representative of the early Celtic migrations. Haplogroup R1b is prevalent within South America because of the influx of Iberian Y chromosomes to the continent over the last 500 years.
- Y-DNA Results
The Y-chromosome results consist of a table of markers tested (numbering from 1 to 33 see above) and a corresponding value for each. Each marker is a specific location on the Y-chromosome and is referred to by its DNA Y-chromosome Segment number (DYS number).
The portions of the Y-chromosome tested are known to produce repeating patterns of nucleotides (the building blocks of DNA.) These Short Tandem Repeats (STRs) are counted at each marker and reported as the DNA result. The profile of repeats is inherited from my father and is what differentiates my specific paternal lineage from another's.
The extent to which the Y-DNA results match other participants will determine how closely related I might be by providing an estimate of how far in the past I shared a common ancestor.
Each of the names of the Y-chromosome locations available for testing are presented in the table. A dash, "-", shown in specific boxes in the table means that results were not produced for that particular location because of two possible factors. First, for markers DYS19b, DYS464e and DYS464f, a lack of result may be due to the fact that these allele results are very rare. Second, the dash may signify the presence of a marker value that cannot be obtained using the current testing methodology.
