The DNA Ancestry Blog has a new post about needs and concerns regarding Ancestry.com’s DNA project. If you have something insightful or valuable to share, the post lists an email address.
There’s a relatively new Genetic Genealogy blog called Haplogroup I which has some interesting information and news about the field. Welcome to the blogosphere, and I hope to learn more about you and about Haplogroup I!
The big news (ok, not really) in Genetic Genealogy this week is that Ben Affleck is joining the Genographic Project. The Boston Globe has a story here. My favorite part was the ending:
As with any other test, the project did lead to some bragging rights. Ramiro Torres, who hosts a morning show on radio station Jam’n 94.5, was pleased to learn his enterprising relatives trekked across all of Asia before crossing the ice bridge and populating North and South America.
I also saw a recent story in the IndyStar called “Unearthing Their Roots“, about African Americans using DNA in an attempt to identify their ancestral origin.Â Although this exact topic has been very popular in the press this year, this article is more balanced than some.
By the way, I would like to remind everyone that Roots Television is a great resource for anyone who might be interested in genetic genealogy, or genealogy in general.Â I especially enjoy seeing interviews and presentations from conferences that I am unable to attend.Â It’s a wonderful resource.
A lot of people write me to ask me questions about genetic genealogy, and a few have asked if there are any books on the subject that might help them learn more about it.Â I thought I should provide a list of great reading material to help someone who might not have time to ask (but keep the questions coming!).
Great beginner books which are specifically about genealogy and DNA:
Trace Your Roots with DNA: Use Your DNA to Complete Your Family Tree by Megan Smolenyak and Ann Turner (Published October 7, 2004):
The Seven Daughters of Eve: The Science That Reveals Our Genetic Ancestry by Bryan Sykes (Published July 9, 2001):
How to Interpret Your DNA Test Results for Family History & Ancestry: Scientists Speak Out on Genealogy Joining Genetics by Anne Hart (Published December 2002):
1.You got those big blue eyes from your grandmother, but chances are you inherited less desirable genes as well.We inherit our DNA from our parents, who inherited it from their parents.Since we all possess genes that can cause or contribute to disease, knowing oneâ€™s DNA and family medical history can be a great resource for someone who learns they have a genetic disorder.
2.Full genome sequencing is right around the corner!The X-prize quest for the $1000 genome will lead to efficient and affordable whole-genome sequencing.As commercial companies crop up and compete for customerâ€™s business, leading to even lower prices.
3.Your grandmotherâ€™s DNA contains clues to her ancestry.X-chromosome, mtDNA, and autosomal genealogy tests contain clues to a personâ€™s ancestry, both recent and ancient.
In the article, Mr. Elgan imagines an enormous future database that combines traditional genealogical records and DNA to link everyone together.Â Two individuals could then, for instance, search the database to find their closest relationship to each other.Â My first thought, of course, is of privacy issues and plain old bad genealogical data (of which the internet is full).
I’ve spoken before about the enormous effect that affordable SNP and whole-genome sequencing will have on genetic genealogy. In that previous article, I mentioned a study using SNP analysis to identify a person’s ancestry based on autosomal DNA (all the nuclear non-sex DNA). Another study, released today inPLoS Genetics, used SNP chips to identify SNP markers that are characteristic of a certain ancestral origins. According to the authors:
“We have developed a novel algorithm to identify a subset of SNP markers that capture major axes of genetic variation in a genotypic dataset without use of any prior information about individual ancestry or membership in a population.”
To accomplish this, the researchers:
“…studied here 274 individuals from 12 populations (20 Mbuti, 20 Mende, 22 Burunge, 42 African Americans, 42 Caucasians, 20 Spanish, 11 Mala, 20 East Asians, 20 South Altaians, 20 Nahua, 20 Quechua, and 19 Puerto Ricans). Three of these populations are admixed (Caucasians, African Americans, and Puerto Ricans). All individuals were typed using the 10K Affymetrix array.”
In todayâ€™s Washington Post thereâ€™s a story about The Boy in the Iron Coffin.This coffin was accidentally discovered by a construction crew in Washington, D.C. in 2003.Research conducted by the Smithsonianâ€™s Museum of Natural History discovered that the body inside, still wearing a white burial suit, was that of William T. White, about age 15.William, who appears to have had a heart defect that would have made him sickly, died on January 23, 1852:
â€œThe boy was extremely well preserved and clad in white cotton clothing that included a pleated shirt and vest with cloth-covered buttons, flared trousers, darned socks and ankle-length underdrawers.â€
According to the article, the body â€œhad been buried in a cemetery that probably belonged to Columbian College, the precursor to GeorgeWashingtonUniversity, in what is now Columbia Heights, and had been a student at the college preparatory school when he died.â€
On the heels of last week’s announcement that Sorenson Molecular Genealogy Foundation (SMGF) will be collecting DNA samples in Mongolia comes new information that the company will be conducting a similar project in Panama.
According to the announcement, SMGF has partnered with the Gorgas Memorial Institute (Instituto Conmemorativo Gorgas de Estudios de la Salud Panama) and will attempt to collect 1,500 to 2,000 DNA samples with pedigree charts.The project will gather DNA from each of Panamaâ€™s nine provinces and three territories and will include individuals from all major ethnic groups, and from both urban and rural areas:
“We are honored to join with Gorgas Memorial Institute, Panama‘s primary institute for health and population studies, to study this country’s diverse, multi-faceted populations,” said Dr. Scott Woodward, executive director of the Sorenson Molecular Genealogy Foundation. “Panama is a fascinating melting pot, its genetic and cultural mix having been influenced by a broad array of Native American populations, Africans from the slave trade, and Europeans and Asians from multiple eras.”
Commercially available genetic genealogy isn’t just for Americans and Europeans anymore. Eastern Biotech & Life Sciences, centered in Dubai, recently sent me an email announcing their new venture into the field of genetic genealogy testing.
Although it wasn’t apparent from the email that I received, Eastern Biotech & Life Sciences has partnered with Family Tree DNA to offer genetic genealogy testing. The following sentence comes from a press release at i-newswire: “Eastern Biotech & Life Sciences is proud to be associated with Family Tree DNA to create a database for the Middle Eastern population.”
From the Email:
“Dubai: 09/12/2007-Eastern Biotech & Life Sciences is set to launch a new Wall Chart of DNA Ancestry services to the people of the Middle East to help them invent their deep ancestors from 150,000 years ago. The roots of this tree lie more than 100,000 years in the past, at a time when our hunter-gatherer ancestors were living in Africa. As the branches of the tree multiply, they record the history of our species and the dramatic stories of how pioneering groups of humans explored and populated our planet. The different journeys they made shaped the world we know today.
