My Genography Report - My Haplogroup

After a long waiting I got result of my DNA test. I submitted my DNA to National Geography channel as a part of a project called Genography.
Genography is a project undertaken by IBM. NGC and Watts Family fund. The aim of this project is to find the migration route of ancient human. As per them the Early human evolved in Africa and later in some point of time went out of africa and populated the entire world. This is possible by analysing our DNA for Y chromosome mutation. Un like other chromosome, Y chromosome did not change much, change in Y chromosome is rare and the change is passed generation to generation. This mutation is called as Marker. These markers can be identified and classified with avilable data. In short humans can be classified in terms of Y chromosome mutation. They are classified as Y-DNA Haplogroup.

I was interested to know what group I belong to and here is the result.
I belong to Haplogroup H ( M 69)
This is the result send by National Geographic:

Your Y-chromosome results identify you as a member of haplogroup H.

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 M69, the defining marker of haplogroup H. Genetic marker M69 also defines haplogroup H*.

If you look at the map highlighting your ancestors' route, you will see that members of haplogroup H carry the following Y-chromosome markers:
M168 > M89 > M69

This lineage represents one of the very earliest pre-historic migrations into India, and today this line of descent is rarely found outside of India.

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/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.

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: Semi-arid grass plains
Estimated Number of Homo sapiens: Tens of thousands
Tools/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.

M69: The Indian Marker
Fast Facts:
Time of Emergence: 30,000 years ago
Place: India, or possibly southern Central Asia
Climate: Ice Age
Estimated Number of Homo sapiens: Hundreds of thousands
Tools/Skills: Upper Paleolithic
Your next male ancestor was part of the group that migrated east along the steppe superhighway, continuing toward India. He was born approximately 30,000 years ago, and gave rise to the M69 lineage. Although M69 is known as an "Indian Marker," this male ancestor may have been born in southern Central Asia. His descendants were part of the first major inland settlement of India.
Geneticists believe that this man and his descendants might have originated somewhere along the migration route of peoples carrying the M20 Y-chromosome marker (haplogroup L, known as the Indian Clan). The peoples of the Indian Clan migrated along the steppe highway from the Middle East, and then moved south of the mountainous Pamir Knot, and into India.

More on Haplogroup H (M69) - YDNA:
It is a branch of Haplogroup F, and is believed to have arisen in India between 20,000 and 30,000 years ago. Its probable site of introduction is India since it is concentrated there. It seems to represent the main Y-haplogroup of the indigenous paleolithic inhabitants of India, because it is the most frequent Y-haplogroup of tribal populations (25-35%). On the other hand, its presence in upper castes is quite rare (ca. 10%) (Cordaux et al. 2004, Sengupta et al. 2006, Thanseem et al. 2006).
