Thanks for sharing this website and the external link "Genealogy by DNA; Can it Deliver?" which includes the caution below retrieved from http://en.wikipedia.org/wiki/Melungeon_DNA_Project
:
Some firms require clients to sign psychological releases absolving companies from responsibility if results don't jibe with client expectations. However; Bruce Jackson, a molecular geneticist at Boston University, who has launched the African-American DNA Roots Project, along with biologist Bert Ely of the University of South Carolina, cautions that "like anything on the Internet, this is all a case of 'caveat emptor' - let the buyer beware. But the science is valid. There's no doubt about the science." He sees DNA as "the hottest new tool" in genealogy, which is why Web sites on the subject run second only in hits to pornography pages. With those kind of statistics, it is easy to see that this "hot new tool' is going to be marketed and hyped to the hilt.
Unfortunately, sometimes the hype exceeds the actual benefit that can reasonably be expected to accrue. Minorities, in particular, are targeted. Because most black African Americans do not know what part of Africa their ancestors came from, or what tribe, they are immensely interested to find out anything that will give them a connection to their mother country. So is learning that you have a genetic marker that is shared by a widespread group of people in Africa worth $349.? That would, of course, depend on your curiosity and finances. Is the hype promising a greater benefit than can be delivered? Some bio-ethicists say the sales pitch raises unreasonable expectations. "DNA is going to be very important and it’s on the cutting edge,” said professional genealogist Tony Burroughs, who teaches at Chicago State University. “But it’s not a panacea. You’re not going to discover your entire family tree from a little spit on a cotton swab.”Burroughs, author of “Black Roots: A Beginners Guide to Tracing the African American Family Tree” argues that DNA can’t replace old-fashioned reporting work.But rather, he feels genealogical breakthroughs will come from uncovering previously forgotten written records. He’s after names, addresses and other hard facts.
