How to Interpret Results
Above are results from the laboratory analysis of your Y-chromosome. Your DNA was analyzed for Short Tandem Repeats (STRs), which are repeating segments of your genome that have a high mutation rate. The location on the Y chromosome of each of these markers is depicted in the image, with the number of repeats for each of your STRs presented to the right of the marker. For example, DYS19 is a repeat of TAGA, so if your DNA repeated that sequence 12 times at that location, it would appear: DYS19 12. Studying the combination of these STR lengths in your Y Chromosome allows researchers to place you in a haplogroup, which reveals the complex migratory journeys of your ancestors. Y-SNP: In the event that the analysis of your STRs was inconclusive, your Y chromosome was also tested for the presence of an informative Single Nucleotide Polymorphism (SNP). These are mutational changes in a single nucleotide base, and allow researchers to definitively place you in a genetic haplogroup.
YOUR GENETIC HISTORY
Your Y-chromosome results identify you as a member of haplogroup R1.
The genetic markers that define your ancestral history reach back roughly 60,000 years to the first common marker of all non-African men, M168, and follow your lineage to present day, ending with M173, the defining marker of haplogroup R1.
If you look at the map highlighting your ancestors' route, you will see that members of haplogroup R1 carry the following Y-chromosome markers:
M168 > P143 >M89 > L15 > M9 > M45 > M207 > M173
(Less is known about some markers thank others. What is known about your journey is reflected below.)
What's a haplogroup, and why do geneticists concentrate on the Y chromosome in their search for markers? For that matter, what's a marker?
Each of us carries DNA that is a combination of genes passed from both our mother and father, giving us traits that range from eye color and height to athleticism and disease susceptibility. One exception is the Y chromosome, which is passed directly from father to son, unchanged, from generation to generation.
Unchanged, that is unless a mutation—a random, naturally occurring, usually harmless change—occurs. The mutation, known as a marker, acts as a beacon; it can be mapped through generations because it will be passed down from the man in whom it occurred to his sons, their sons, and every male in his family for thousands of years.
In some instances there may be more than one mutational event that defines a particular branch on the tree. This means that any of these markers can be used to determine your particular haplogroup, since every individual who has one of these markers also has the others.
When geneticists identify such a marker, they try to figure out when it first occurred, and in which geographic region of the world. Each marker is essentially the beginning of a new lineage on the family tree of the human race. Tracking the lineages provides a picture of how small tribes of modern humans in Africa tens of thousands of years ago diversified and spread to populate the world.
A haplogroup is defined by a series of markers that are shared by other men who carry the same random mutations. The markers trace the path your ancestors took as they moved out of Africa. It's difficult to know how many men worldwide belong to any particular haplogroup, or even how many haplogroups there are, because scientists simply don't have enough data yet.
Your Ancestral Journey: What We Know Now
M168: Your Earliest Ancestor
Time of Emergence: Roughly 50,000 years ago
Place of Origin: Africa
The next male ancestor in your ancestral lineage is the man who gave rise to M89, a marker found in 90 to 95 percent of all non-Africans. This man was born around 45,000 years ago in northern Africa or the Middle East.
The first people to leave Africa likely followed a coastal route that eventually ended in Australia. Your ancestors followed the expanding grasslands and plentiful game to the Middle East and beyond, and were part of the second great wave of migration out of Africa.
Beginning about 40,000 years ago, the climate shifted once again and became colder and more arid. Drought hit Africa and the grasslands reverted to desert, and for the next 20,000 years, the Saharan Gateway was effectively closed. With the desert impassable, your ancestors had two options: remain in the Middle East, or move on. Retreat back to the home continent was not an option.
While many of the descendants of M89 remained in the Middle East, others continued to follow the great herds of buffalo, antelope, woolly mammoths, and other game through what is now modern-day Iran to the vast steppes of Central Asia.
These semiarid grass-covered plains formed an ancient "superhighway" stretching from eastern France to Korea. Your ancestors, having migrated north out of Africa into the Middle East, then traveled both east and west along this Central Asian superhighway. A smaller group continued moving north from the Middle East to Anatolia and the Balkans, trading familiar grasslands for forests and high country.
M9: The Eurasian Clan Spreads Wide and Far
Time of Emergence: 40,000 years ago
Place: Iran or southern Central Asia
Estimated Number of Homo sapiens: Tens of thousands
Tools and Skills: Upper Paleolithic
Your next ancestor, a man born around 40,000 years ago in Iran or southern Central Asia, gave rise to a genetic marker known as M9, which marked a new lineage diverging from the M89 Middle Eastern Clan. His descendants, of which you are one, spent the next 30,000 years populating much of the planet.
This large lineage, known as the Eurasian Clan, dispersed gradually over thousands of years. Seasoned hunters followed the herds ever eastward, along the vast super highway of Eurasian steppe. Eventually their path was blocked by the massive mountain ranges of south Central Asia—the Hindu Kush, the Tian Shan, and the Himalayas.
The three mountain ranges meet in a region known as the "Pamir Knot," located in present-day Tajikistan. Here the tribes of hunters split into two groups. Some moved north into Central Asia, others moved south into what is now Pakistan and the Indian subcontinent.
These different migration routes through the Pamir Knot region gave rise to separate lineages.
Most people native to the Northern Hemisphere trace their roots to the Eurasian Clan. Nearly all North Americans and East Asians are descended from the man described above, as are most Europeans and many Indians.
The next marker of your genetic heritage, M45, arose around 35,000 years ago, in a man born in Central Asia. He was part of the M9 Eurasian Clan that had moved to the north of the mountainous Hindu Kush and onto the game-rich steppes of present-day Kazakhstan, Uzbekistan, and southern Siberia.
After spending considerable time in Central Asia, refining skills to survive in harsh new conditions and exploit new resources, a group from the Central Asian Clan began to head west towards the European subcontinent.
An individual in this clan carried the new M207 mutation on his Y chromosome. His descendants ultimately split into two distinct groups, with one continuing onto the European subcontinent, making this man the ancestor of most Western European men alive today.
But your genetic lineage does not descend from this westward migrating band of hunter-gatherers. The second group did not head west into Europe, but rather likely turned south, ultimately ending their journey in the Indian subcontinent and giving rise to many men whose lineages survive there today. This distribution adds weight to linguistic and archaeological evidence suggesting that a large migration from the Asian steppes into India occurred within the last 10,000 years.
However, the ancient migrations of this second group, and the distribution of genetic lineages that it ultimately gave rise to, still remain largely a mystery. This is because we have precious little data with which to uncover the history of this haplogroup. We encourage you to contribute your anonymous results to the project database—click the "How you can help" button at the bottom of the page to learn more. By doing this you will be helping our geneticists learn more about your specific genetic lineage, the results of which will be communicated directly back to you via this results page
Members of haplogroup R1 are descendents of Europe's first large-scale human settlers. The lineage is defined by Y-chromosome marker M173, which shows a westward journey of M45-carrying Central Asian steppe hunters.
The descendents of M173 arrived in Europe around 35,000 years ago and immediately began to make their own dramatic mark on the continent. Famous cave paintings, like those of Lascaux and Chauvet, signal the sudden arrival of humans with artistic skill. There are no artistic precedents or precursors to their appearance.
