Is That True That People Can Trace Their Ancestor Lines Via Ancestor Dna Testing?
Genealogy research has been one upcoming and popular thing when one of the most sought talk show celebrities, Oprah Winfrey announced on her show that DNA testing has managed to track her origin ethnic to a Kpelles tribe located in Liberia.
Then, with all the extensive studies and affordability of genealogical DNA tests like the Genographic Project, annual sales have been increasingly rising where an estimated $60 million was recorded in year 2006.
Then, why people are interested in finding their origin? Is it because they are looking to validate or invalidate their genealogical records? Do they have or suspected any surname change or adoption in the line?
Are they looking to verify the relationships with a family from a region where they believed their family has lived? Or do they believe that they have a common ancestor with another individual or group? Actually all the reasons mentioned are true.
However, the right reasons for the existence of DNA test kits seem rational but whether the $70 to $900 ranging DNA testing provided could pinpoint exactly your ancestor origin is another story.
The two most common tests in genealogy kits examine the paternally inherited Y chromosome (Y-DNA), which is passed down from father to son, and the mtDNA (mitochondrial DNA) that is passed down from mother to child.
Another test links to autosomal DNA, which is inherited from both parents. However, it is most likely that one small part of your family tree can be concluded. Like the mtDNA test, the information only could track you back to only one of your 16 great grandparents.
Referring to the lack of approach in ancestry testing technology, Professor Easteal – a leading molecular geneticist has quickly slammed online and availability of direct-to-customer DNA ancestry testing in the markets now.
He claimed that they only helped to track down human variation that emerged in population over time and not individual ancestry information.
Your DNA information is just many of the tools that we can use to confirm what we know, or find out something new about your ancient heritage.
It’s fascinating that our cells contain information about our history and that we hold on to the hidden treasure for eternity.

Deep Ancestry (Paperback) $21.97 The fossil record locates human origins in Africa, but little is known about the great journey that took Homo sapiens to the far reaches of the Earth. How did we, each of us, end up where we are? Why do we appear in such a wide array of different colors and features? Such questions are even more amazing in light of genetic evidence that we are all related–descended from a com- mon African ancestor who lived only 60,000 years ago. Thanks to new genetic testing methods, we now know that the greatest history book ever written is the one hidden in our DNA.In Deep Ancestry, geneticist and explorer Spencer Wells unravels the slight changes in our DNA over time to tell the ancient story of our shared human journey. He also details the current work of Genographic Project–the landmark study that will assemble the world`s largest collection of DNA samples to map how humankind populated the planet. He describes how the Project uses sophisticated computer analysis of DNA contributed by hundreds of thousands of people–including indigenous populations and the general public–to reveal man`s migratory history and to better understand the connections and differences that make up the human race. The narrative works backward, starting from today and gradually working its way to humankind`s common ancestors. From the beginning, the book taps into a reader`s interest in genealogy, family history, and ethnic identity. Most of us have a decent sense of our family history, but eventually we all hit a brick wall. DNA takes us beyond it, and this is the unifying theme that will lead us from the stories of the present into the realm of deep ancestry. Now in a thoroughly revised second edition, Deep Ancestry represents the very latest research on where we came from and relates it to our own personal quest to discover the deep ancestry behind our family genealogies and touch the depths of our common origins.For more information about the Genogr |
