ThinkGenealogy Presents "Are You Smarter than a Grade School Genealogist?"

ThinkGenealogy introduces episode 1 of “Are You Smarter than a Grade School Genealogist?“: “Match your genealogy knowledge against a grade schooler to determine: Are You Smarter than a Grade School Genealogist? In this episode, Nathan, a 4th grader from Arizona introduces DNA for the genealogist.” The episode is just over 4 minutes long and is a great introduction to genetic genealogy.

Genetic Genealogy on TV – Meeting David Wilson

MSNBC will air a documentary tomorrow evening about the journey of 28-year-old African American David Wilson as he discovers his genealogical roots. Wilson uses both traditional genealogical research as well as DNA testing to learn more about his ancestry. Along the way, Wilson meets another David Wilson, a white 62-year-old descendant of the slaveowners who owned the other’s ancestors. From the Meeting David Wilson website:

“Coinciding with the 40th anniversary of the assassination of civil rights leader Dr. Martin Luther King, Jr., MSNBC will premiere “Meeting David Wilson,” the remarkable and inspiring story of a young man’s reconciliation with his ancestors’ history as slaves. The world premiere of “Meeting David Wilson,” on April 11 at 9 p.m. ET will be hosted by “Today” Correspondent Tiki Barber and followed by a 90-minute live discussion of racial issues in America. The live event will be moderated by “NBC Nightly News” Anchor and Managing Editor Brian Williams and held at Howard University in Washington, D.C.”

Navigenics Open For Business

Navigenics, a genome scanning company, officially launches their genome service today – called the “Navigenics Health Compass”, with a cocktail reception in NYC tonight at 6:00PM. Thomas Goetz of Epidemix writes an article in Wired today about some of the differences between Navigenics and other large-scale genome scanning companies.

The launch is also mentioned in an exclusive interview at Genetics and Health with Navigenics’ medical director, Dr. Michael Nierenberg. This piece is the first article in a seven article series, including the future article 6, which discusses some of my favorite things: “Privacy, insurance, GINA, and ethics.” I’ll be sure to link to that article when it comes out. The launch is also discussed over at ScienceRoll.

Genetic Testing Under the Microscope

Genetic Testing Under the Microscope Genetic testing has once again come under the microscope, triggered by an article in the journal Science: “A Case Study of Personalized Medicine.”

In my opinion, adding to the conversation about genetic testing is always a good thing.

That being said, my biggest complaint with many of these articles (especially in the popular media) is that they tend to lump together every test that examines DNA. There are different types of genetic testing with different levels of quality control, interpretation, etc. The results, scientific background, and effects of tests offered by large-scale genome scanning companies, clinical entities, direct-to-consumer companies, and pharmacogenetic companies are not the same. When dealing with a readership that does not have a background in genetics (which is probably 99% of the readership), the media should take extra care to note these differences. Lumping every DNA test together does little to properly educate the public.

The 2010 Census

At 12:01 on April 1, 2082, millions of genealogists around the solar system will be able to instantaneously download every image from the 2010 census into their neural storage chip, and within minutes these images will be linked to the ancestors in their 3D holographic family trees. Almost all of these genealogists will be able to find themselves in these census images and index.

Okay, maybe it’s a little premature to guess about the use of a census that hasn’t even been enumerated yet, but as most genealogists know, census results are the backbone of the genealogical world. Only one census has been released since the advent of the internet. In 2002 the 1930 census was released, and the countdown to the April 2, 2012 release of the 1940 census has already begun.

Abstract From the New Y-Chromosome Haplogroup Tree Article

Here is the abstract of today’s Y-chromosome haplogroup tree paper in Genome Research, I’m still working to get a copy of the actual paper (unfortunately, it’s not open access at this time):

Markers on the non-recombining portion of the human Y chromosomecontinue to have applications in many fields including evolutionarybiology, forensics, medical genetics, and genealogical reconstruction.In 2002, the Y Chromosome Consortium published a single parsimonytree showing the relationships among 153 haplogroups based on243 binary markers and devised a standardized nomenclature systemto name lineages nested within this tree. Here we present anextensively revised Y chromosome tree containing 311 distincthaplogroups, including two new major haplogroups (S and T),and incorporating approximately 600 binary markers. We describemajor changes in the topology of the parsimony tree and providenames for new and rearranged lineages within the tree followingthe rules presented by the Y Chromosome Consortium in 2002.Several changes in the tree topology have important implicationsfor studies of human ancestry. We also present demography-independentage estimates for 11 of the major clades in the new Y chromosometree.

The New Y-Chromosome Tree to be Released Tomorrow

A long-anticipated new version of the Y-Chromosome Tree will be released in the journal Genome Research tomorrow (Wednesday, April 2nd). In the paper, scientists from the University of Arizona and Stanford University use recent SNP data and research to reformulate the familiar Y-chromosome tree (see, for example, the current tree at ISOGG). Here is the full text of the press release.  The paper should appear here as soon as it is made available by Genome Research tomorrow.

From the press release:

In an article published online today in Genome Research (www.genome.org), scientists have utilized recently described genetic variations on the part of the Y chromosome that does not undergo recombination to significantly update and refine the Y chromosome haplogroup tree. The print version of this work will appear in the May issue of GenomeResearch, accompanied by a special poster of the new tree.

Interesting DNA Links – March 26, 2008

Here are a few of the many interesting links from the DNA blogosphere:

  • DNA Testing Firms Eye Consumers (BBC) – yet another article that looks at both sides of the “should you test” debate.
  • Genetic Testing Gets Personal (Washington Post) – a lengthy discussion of many different types of DNA testing.
  • The Scientific Studies/Papers Page at ISOGG – I’ve been meaning to share this one for a while. The page describes methods for obtaining and reading scientific papers about genetic genealogy (or any other scientific topic, for that matter). This is a helpful resource for anyone who is interested in learning more about the science behind genetic genealogy.
