mt-DNA Haplogroup Descriptions
All Haplogroup Descriptions below are taken from FamilyTreeDNA, the company I am using for my project. I am using these descriptions with FamilyTreeDNA's permission.
Specific mitochondrial haplogroups are typically found in different regions
of the world, and this is due to unique population histories. In the process of
spreading around the world, many populations—with their special mitochondrial
haplogroups—became isolated, and specific haplogroups concentrated in geographic
regions. Today, we have identified certain haplogroups that originated in
Africa, Europe, Asia, the islands of the Pacific, the Americas, and even
particular ethnic groups. Of course, haplogroups that are specific to one region
are sometimes found in another, but this is due to recent migration.
H: Mitochondrial haplogroup H is a predominantly European haplogroup
that participated in a population expansion beginning approximately 20,000 years
ago. Today, about 30% of all mitochondrial lineages in Europe are classified as
haplogroup H. It is rather uniformly distributed throughout Europe suggesting a
major role in the peopling of Europe, and descendant lineages of the original
haplogroup H appear in the Near East as a result of migration. Future work will
better resolve the distribution and historical characteristics of this
haplogroup. Bryan Sykes in his Seven Daughters of Eve book named this mtDNA
haplogroup Helena.
K: The mitochondrial super-haplogroup U encompasses haplogroups U1-U7 and
haplogroup K. Haplogroup K is found through Europe, and contains multiple
closely related lineages indicating a recent population expansion. The origin of
haplogroup K dates to approximately 16,000 years ago, and it has been suggested
that individuals with this haplogroup took part in the pre-Neolithic expansion
following the Last Glacial Maximum. Bryan Sykes in his Seven Daughters of Eve
book named this mtDNA haplogroup Katrine.
U2: Mitochondrial haplogroup U2.
U5: The mitochondrial super-haplogroup U encompasses haplogroups U1-U7
and haplogroup K. Haplogroup U5, with its own multiple lineages nested within,
is the oldest European-specific haplogroup, and its origin dates to
approximately 50,000 years ago. Most likely arising in the Near East, and
spreading into Europe in a very early expansion, the presence of haplogroup U5
in Europe pre-dates the expansion of agriculture in Europe. Haplogroup U5a1—a
lineage within haplogroup U5—arose in Europe approximately 30,000 years ago, and
is mainly found in northwest Europe. In the context of its rather ancient
origin, the modern distribution of haplogroup U5a1 suggests that individuals
bearing this haplogroup were part the initial expansion tracking the retreat of
ice sheets from Europe. Bryan Sykes in his Seven Daughters of Eve book named
this mtDNA haplogroup Ursula.
U6: The mitochondrial super-haplogroup U encompasses haplogroups U1-U7
and haplogroup K. Bryan Sykes in his Seven Daughters of Eve book named this
mtDNA haplogroup Ursula.
U7: The mitochondrial super-haplogroup U encompasses haplogroups U1-U7
and haplogroup K. Haplogroup U7 has a Near Eastern origin approximately 30,000
years ago. Within Europe, it occurs at low frequency in the Caucasus. Bryan
Sykes in his Seven Daughters of Eve book named this mtDNA haplogroup Ursula.
HV: Mitochondrial haplogroup HV is a primarily European haplogroup that
underwent an expansion beginning approximately 20,000 years ago. It is more
prevalent in western Europe than in eastern Europe, and descendant lineages of
the original haplogroup HV appear in the Near East as a result of more recent
migration. One of the dominant mitochondrial haplogroups in Europe, haplogroup
HV pre-dates the occurrence of farming in Europe. Future work will better
resolve the distribution and historical characteristics of this haplogroup.
I: Principally a European haplogroup, haplogroup I is detected at very
low frequency across west Eurasia with slightly greater representation in
northern and western Europe. Given its wide, but sparse, distribution, it is
likely that it was present in those populations that first colonized Europe.
This hypothesis is supported by the estimate its age—approximately 30,000 years.
Bonnie Schrack in her mtDNA Haplogroup I project named this mtDNA haplogroup
Iris.
J*: The mitochondrial haplogroup J contains several sub-lineages. The
original haplogroup J originated in the Near East approximately 50,000 years
ago. Within Europe, sub-lineages of haplogroup J have distinct and interesting
distributions. Haplogroup J* — the root lineage of haplogroup J — is found
distributed throughout Europe, but at a relatively low frequency. Haplogroup J*
is generally considered one of the prominent lineages that was part of the
Neolithic spread of agriculture into Europe from the Near East beginning
approximately 10,000 years ago. Bryan Sykes in his Seven Daughters of Eve book
named this mtDNA haplogroup Jasmine.
J1b1: The mitochondrial haplogroup J contains several sub-lineages. The
original haplogroup J originated in the Near East approximately 50,000 years
ago. Within Europe, sub-lineages of haplogroup J have distinct and interesting
distributions. Haplogroup J1b is found distributed in the Near East and southern
Iberia, and may have been part of the original colonization wave of Neolithic
settlers moving around the Mediterranean 6000 years ago or perhaps a lineage of
Phoenician traders. Within haplogroup J1b, a derivative lineage haplogroup J1b1
has been found in Britain and another sub-lineage detected in Italy. Further
research will better establish the relationship of these two geographically
distant, yet evolutionarily related, haplogroups. Bryan Sykes in his Seven
Daughters of Eve book named this mtDNA haplogroup Jasmine.
N*: Haplogroup N*.
T: Haplogroup T is believed to have lived around 17,000 years ago in
Nothern Italy. Tara's people would have come from the Near East, and her
descendents spread all over Europe. Bryan Sykes in his Seven Daughters of Eve
book named this mtDNA haplogroup Tara.
V: Bryan Sykes in his Seven Daughters of Eve book named this mtDNA
haplogroup Velda.
A, B, C, & D: Haplogroups A, B, C, & D. Native American mtDNA Haplogroups.
X: Haplogroup X is found in Europe and Asia, and is believed to have
migrated to the Americas about 15,000 years ago, making up a very small
component of the Native American population. Bryan Sykes in his Seven Daughters
of Eve book named this mtDNA haplogroup Xenia.
