SKINNER FAMILY NORTHWEST
GENETIC LINEAGE
The National Geographic Society has developed a program to track your original
genetic lineage from genetic analysis worldwide. The program is called Genographic
where DNA samples are provided and analyzed to track your original lineage.
Michael Kirtland Skinner provided his DNA and the information on the analysis
and lineage are provided below. The Skinner Family Northwest lineage came from
the Eurasian Adam as shown below over 30-80 thousand years. This indicates the
lineage came from Northern Europe and likely England to subsequently settle
on the Isle of Man. This indicates we did not come from Celtic background but
Northern Europe and English background. Therefore, the Ewan Skinner background
was likely English prior to 1600.
Skinner Family Genetic Migration Map
The genetic sequence and analysis described below provides the result for the
genetic lineage for the Skinner Family Northwest original migration from Africa
to Northern Europe.
YOUR GENETIC SEQUENCE
Type Y-Chromosome
Haplogroup R1b, M343 (Subclade R1b1b2, M269)
Your STRs
DYS393: 13 DYS439: 11 DYS388: 12 DYS385a: 11
DYS19: 15 DYS389-1: 13 DYS390: 23 DYS385b: 12
DYS391: 11 DYS389-2: NaN DYS426: 12 DYS392: 13
How to Interpret Your 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.
*NB: If your results indicate "null," this is a situation in which
the lab was unable to obtain a result for this marker (aka location) in your
DNA. Possible causes include a deletion in your DNA sequence that removed the
entire marker, or a mutation near the marker that causes the test to be unable
to "find" the marker in order to test it. While uncommon, this does
occur occasionally.
YOUR GENETIC HISTORY
Your Y-chromosome results identify you as a member of haplogroup R1b, M343 (Subclade
R1b1b2, M269).
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 M343, the defining marker of Haplogroup R1b.
If you look at the map highlighting your ancestors' route, you will see that
members of haplogroup R1b carry the following Y-chromosome markers:
M168 > P143 > M89 > L15 > M9 > M45 > M207 > M173 > M343
(Less is known about some markers than others. What is known about your journey
is reflected below.)
Today, roughly 70 percent of the men in southern England belong to haplogroup
R1b. In parts of Spain and Ireland, that number exceeds 90 percent.
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.
One of the goals of the five-year Genographic Project is to build a large enough
database of anthropological genetic data to answer some of these questions.
To achieve this, project team members are traveling to all corners of the world
to collect more than 100,000 DNA samples from indigenous populations. In addition,
we encourage you to contribute your anonymous results to the project database,
helping our geneticists reveal more of the answers to our ancient past.

about your own genetic history.
Your Ancestral Journey: What We Know Now
M168: Your Earliest Ancestor
Fast Facts
Time of Emergence: Roughly 50,000 years ago
Place of Origin: Africa
Climate: Temporary retreat of Ice Age; Africa moves from drought to warmer temperatures
and moister conditions
Estimated Number of Homo sapiens: Approximately 10,000
Tools and Skills: Stone tools; earliest evidence of art and advanced conceptual
skills
Skeletal and archaeological evidence suggest that anatomically modern humans
evolved in Africa around 200,000 years ago, and began moving out of Africa to
colonize the rest of the world around 60,000 years ago.
The man who gave rise to the first genetic marker in your lineage probably lived
in northeast Africa in the region of the Rift Valley, perhaps in present-day
Ethiopia, Kenya, or Tanzania, some 31,000 to 79,000 years ago. Scientists put
the most likely date for when he lived at around 50,000 years ago. His descendants
became the only lineage to survive outside of Africa, making him the common
ancestor of every non-African man living today.
But why would man have first ventured out of the familiar African hunting grounds
and into unexplored lands? It is likely that a fluctuation in climate may have
provided the impetus for your ancestors' exodus out of Africa.
The African ice age was characterized by drought rather than by cold. It was
around 50,000 years ago that the ice sheets of northern Europe began to melt,
introducing a period of warmer temperatures and moister climate in Africa. Parts
of the inhospitable Sahara briefly became habitable. As the drought-ridden desert
changed to a savanna, the animals hunted by your ancestors expanded their range
and began moving through the newly emerging green corridor of grasslands. Your
nomadic ancestors followed the good weather and the animals they hunted, although
the exact route they followed remains to be determined.
In addition to a favorable change in climate, around this same time there was
a great leap forward in modern humans' intellectual capacity. Many scientists
believe that the emergence of language gave us a huge advantage over other early
human species. Improved tools and weapons, the ability to plan ahead and cooperate
with one another, and an increased capacity to exploit resources in ways we
hadn't been able to earlier, all allowed modern humans to rapidly migrate to
new territories, exploit new resources, and replace other hominids.
M89: Moving Through the Middle East
Fast Facts
Time of Emergence: 45,000 years ago
Place: Northern Africa or the Middle East
Climate: Middle East: Semiarid grass plains
Estimated Number of Homo sapiens: Tens of thousands
Tools and Skills: Stone, ivory, wood tools
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
Fast Facts
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.
M45: The Journey Through Central Asia
Fast Facts
Time of Emergence: 35,000
Place of Origin: Central Asia
Climate: Glaciers expanding over much of Europe
Estimated Number of Homo sapiens: Approximately 100,000
Tools and Skills: Upper Paleolithic
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.
Although big game was plentiful, the environment on the Eurasian steppes became
increasing hostile as the glaciers of the Ice Age began to expand once again.
The reduction in rainfall may have induced desertlike conditions on the southern
steppes, forcing your ancestors to follow the herds of game north.
To exist in such harsh conditions, they learned to build portable animal-skin
shelters and to create weaponry and hunting techniques that would prove successful
against the much larger animals they encountered in the colder climates. They
compensated for the lack of stone they traditionally used to make weapons by
developing smaller points and blades—microliths—that could be mounted
to bone or wood handles and used effectively. Their tool kit also included bone
needles for sewing animal-skin clothing that would both keep them warm and allow
them the range of movement needed to hunt the reindeer and mammoth that kept
them fed.
Your ancestors' resourcefulness and ability to adapt was critical to survival
during the last ice age in Siberia, a region where no other hominid species
is known to have lived.
The M45 Central Asian Clan gave rise to many more; the man who was its source
is the common ancestor of most Europeans and nearly all Native American men.
M207: Leaving Central Asia
Fast Facts
Time of Emergence: 30,000
Place of Origin: Central Asia
Climate: Glaciers expanding over much of Europe and western Eurasia
Estimated Number of Homo sapiens: Approximately 100,000
Tools and Skills: Upper Paleolithic
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, and the other group turning south and eventually
making it as far as India.
Your lineage falls within the first group, M173, and gave rise to the first
modern humans to move into Europe and eventually colonize the continent.
M173: Colonizing Europe—The First Modern Europeans
Fast Facts
Time of Emergence: Around 30,000 years ago
Place: Central Asia
Climate: Ice Age
Estimated Number of Homo sapiens: Approximately 100,000
Tools and Skills: Upper Paleolithic
As your ancestors continued to move west, a man born around 30,000 years ago
in Central Asia gave rise to a lineage defined by the genetic marker M173. His
descendants were part of the first large wave of humans to reach Europe.
During this period, the Eurasian steppelands extended from present-day Germany,
and possibly France, to Korea and China. The climate fostered a land rich in
resources and opened a window into Europe.
Your ancestors' arrival in Europe heralded the end of the era of the Neandertals,
a hominid species that inhabited Europe and parts of western Asia from about
29,000 to 230,000 years ago. Better communication skills, weapons, and resourcefulness
probably enabled your ancestors to outcompete Neandertals for scarce resources.
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, more 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.
The large number of archaeological sites found in Europe from around 30,000
years ago indicates that there was an increase in population size.
Around 20,000 years ago, the climate window shut again, and expanding ice sheets
forced your ancestors to move south to Spain, Italy, and the Balkans. As the
ice retreated and temperatures became warmer, beginning about 12,000 years ago,
many descendants of M173 moved north again to repopulate places that had become
inhospitable during the Ice Age.
Not surprisingly, today the number of descendants of the man who gave rise to
marker M173 remains very high in Western Europe. It is particularly concentrated
in northern France and the British Isles where it was carried by ancestors who
had weathered the Ice Age in Spain.
M343: Direct Descendants of Cro-Magnon
Fast Facts
Time of Emergence: Around 30,000 years ago
Place of Origin: Western Europe
Climate: Ice sheets continuing to creep down Northern Europe
Estimated Number of Homo sapiens:
Tools and Skills: Upper Paleolithic
Around 30,000 years ago, a descendant of the clan making its way into Europe
gave rise to marker M343, the defining marker of your haplogroup. You are a
direct descendent of the people who dominated the human expansion into Europe,
the Cro-Magnon.
The Cro-Magnon are responsible for the famous cave paintings found in southern
France. These spectacular paintings provide archaeological evidence that there
was a sudden blossoming of artistic skills as your ancestors moved into Europe.
Prior to this, artistic endeavors were mostly comprised of jewelry made of shell,
bone, and ivory; primitive musical instruments; and stone carvings.
The cave paintings of the Cro-Magnon depict animals like bison, deer, rhinoceroses,
and horses, and natural events important to Paleolithic life such as spring
molting, hunting, and pregnancy. The paintings are far more intricate, detailed,
and colorful than anything seen prior to this period.
Your ancestors knew how to make woven clothing using the natural fibers of plants,
and had relatively advanced tools of stone, bone, and ivory. Their jewelry,
carvings, and intricate, colorful cave paintings bear witness to the Cro-Magnons'
advanced culture during the last glacial age.
