Colleen Fitzpatrick, Ph.D. is one of the most recognizable names in the field of forensic genealogy.Â She has authored two books entitled Forensic Genealogy and DNA & Genealogy, and continues to make headlines in this fascinating field.Â Here is just an excerpt from her biography, located at her website:
“Colleen Fitzpatrick, Ph.D., is the author of two of the best-selling books in genealogy.Â Forensic Genealogy has been widely recognized for its innovative forensic science approach to genealogical research.Â She has been featured on NPR’s Talk of the Nation radio program (July 2005), and has written cover articles for Internet Genealogy (June 2006), Family Tree Magazine (April 2006) and Family Chronicle (October 2005).Â Colleen writes a regular column for Ancestry magazine.”
See the new article at Seed Magazine “Inheriting Confucius,” which discusses efforts to generate a family tree containing the 2 million+ descendants of Confucius.
Kong De-Yong, a 77th(!) generation descendant of Confucius, has been compiling the tree for the last 10 years.Â Although the Committee is accepting submissions from women and other previously excluded groups, it is not accepting DNA contributions.Â According to the article, this “hints at the limits of Chinese engagement with the age of genomics, and demonstrates how high cultural stakes can constrain science.”Â Unfortunately, as the author of the article suggests, many people might be afraid of the results of such DNA testing: “Given the potential implications of genetic knowledge for long-presumed members of the [Confucius] family, they think it better not to know.”
Technology Review, an MIT publication, has an article entitled “Genealogy Gets More Precise: Rapidly growing databases enable a more complete picture of one’s ancestry.“Â The article, which is relatively balanced, discusses some of the benefits and challenges associated with genetic genealogy testing.
Also check out the article and video “Mapping Out a Nascent Market” at boston.com, which is directed towards personal genetic companies such as deCODEme, 23andMe, Navigenics, and Knome.
And lastly, scientists have sequenced and recreated the Neanderthal mtDNA genome.Â For more information see john hawks weblog, Genetic Archaeology, Genea-Musings (with a humorous twist), Anthropology.net, and The Spittoon.Â The original article is in Cell.Â Turns out there are roughly 206 differences between the CRS (the Cambridge Reference Sequence, the mtDNA to which all human mtDNA is compared) and Neanderthal mtDNA; 195 transitions and 11 transversions.
Yesterday, DNA Heritage issued a press release (reproduced below) regarding an opinion issued by the UK Intellectual Property.The opinion (available here) was the result of inquiry into whether claims 4-7 of a 2004 patent in England are valid.The patent, held by Bryan Sykes of Oxford Ancestors, was issued in 2004 and is directed at creating and using a database of Y-DNA haplotype information to examine surname relationships and determine the likelihood of common ancestry between individuals.The UK IPOâ€™s opinion holds that the claims are invalid because they are either not novel, or did not require an inventive step (i.e., they were obvious).Most intellectual property offices, such as those in the UK and the US, require that an invention at least be novel and nonobvious.
The eighth edition of the TGG Interview Series is with Max Blankfeld.Â Max is Vice-President of Marketing and Operations at Family Tree DNA, one of the largest genetic genealogy companies in the world.Â In addition, together with Bennett Greenspan, Max launched DNA Traits, a company that tests DNA for genetic diseases and inherited conditions.Â Max is a frequent contributor to genetic genealogy mailing lists and has answered many people’s questions about testing, results, an the field in general.
From the “About” page at Family Tree DNA:
“Originally from Brazil, received his BBA from FundaÃ§Ã£o Getulio Vargas, and MBA from Rice University. While his first college education was in the field of Aeronautical Engineering, he gave it up to become a foreign correspondent. After that, he started and managed several successful ventures in the area of public relations as well as consumer goods both in Brazil and the US.”
On June 9, 2008, the California Department of Public Health sent cease and desist letters to 13 companies that offer genetic testing. According to the letters, the companies are in violation of certain sections of the Business and Professions Code of California, including offering “a clinical laboratory test directly to the consumer without a physician order” since such tests “must be ordered by a physician or surgeon” (according to these officials). Copies of the letters are available here. The companies receiving letters are:
- CGC Genetics
- deCODEme Genetics
- DNA Traits
- Gene Essence
- HairDX LLC
- New Hope Medical
- Sciona Inc
- Smart Genetics
- Suracell Inc
I’m entering this discussion late, although I’ve been watching with great interest. What I’ve noticed is that much of the discussion, both in the blogosphere and the media, is confusing or ignoring the fact that there are actually two questions involved here.
GenomeWeb Daily News published a story on Friday entitled “En route to Neandertal Genome, Researchers Analyze Its Complete Mitochondrial Genome” which revealed the results of recent Neanderthal mtDNA analysis.
On Thursday May 9th, Svante PÃ¤Ã¤bo spoke at the Biology of Genomes meeting at Cold Spring Harbor Laboratory. PÃ¤Ã¤bo’s group, along with 454 Life Sciences, is currently engaged in a project to sequence the Neanderthal genome. The researchers have been able to sequence the complete Neanderthal mtDNA genome with 35-fold coverage. The genome is approximately 16 kilobases long and differs from the CRS at 133 positions. From what I’ve been able to find online, it doesn’t appear that the actual sequencing results have been released to the public. Given current estimates of mtDNA mutation rates, the number of differences between human and Neanderthal mtDNA suggests that the branches diverged approximately 600,000 years ago.
Last week I received a press release announcing the creation of a non-profit organization to raise and disseminate funds to increase original research in genetic genealogy testing (some of which will undoubtedly be reported in the open-source Journal of Genetic Genealogy). The DNA Fund also has a blog, available here. Following is the press release:
SALIDA, CA â€“ The DNA Fund, (www.dnafund.org), a new non-profit organization has been established to fund DNA testing scholarships and grants for ancestral DNA studies. Currently in Phase 1 of the Fundâ€™s launch, testing monies will be raised through fundraising affiliates. Scheduled for Phase 2, the Fund will accept donations and in Phase 3, coordinate grants for DNA projects and studies.
Around the year 1700, a relatively healthy young hunter was walking along a glacier in land that would one day be British Columbia in Canada. He wore a robe of 95 animal skins, perhaps gopher or squirrel, stitched together with sinew, and carried a walking stick, iron-blade knife, and spear thrower. For some reason, the young man, aged 17 to 22, died on the glacier and was quickly incorporated into the ice. There he remained, frozen, for the next 300 years.
In August 1999, three hikers noticed a walking stick, fur, and bone lying on a melting glacier (60′ N 138′ W). The young hunter, renamed KwÃ¤day DÃ¤n Tsâ€™Ã¬nchi in the Southern Tutchone language of the Champagne and Aishihik First Nations, was removed by scientists for analysis (see the NY Times article, and the Journal of Canadian Archaeology article). From an article in the Sydney Morning Herald:
Yesterday, a very interesting paper was published in the American Journal of Human Genetics by the Genographic Project Consortium entitled “The Dawn of Human Matrilineal Diversity.” The results of the study, which examined the 624 mtDNA genomes from sub-saharan Haplogroup L lineages, suggests that humanity once split into two small groups with one group in eastern Africa and the other in southern Africa, and that humanity bottlenecked into a relatively small number of individuals (as few as 2,000 based on results from a previous study). Note, as always, that these are hypotheses based upon the results of this and other studies, and will require further research to support or refute.
Two mtDNA Branches
The human mtDNA tree has two main branches, the L0 branch which includes individuals concentrated in southern and eastern Africa, and the L1’2’3’4’5’6′ branch (aka the L1’5 branch), which includes the entire remainder of humanity including non-Africans (see the figure to the left). Based upon the analysis of the 624 genomes, the researchers hypothesized that the L0 and L1’5 branches diverged into two small populations around 140,000 to 210,000 years ago, with one group settling in eastern Africa (the L1’5 branch) and the other settling in southern Africa (the L0 branch). Interestingly, the results also suggest that there was little to no intermingling of these branches for the next 50,000 to 100,000 years!
