Scientists Gather at National Geographic Headquarters

The Genographic Project scientists gathered at National Geographic headquarters in early November for a week of scientific discussion and global collaboration. In from the field from over 14 different countries in some of the most remote areas of the world, the scientists discussed their recent research and upcoming opportunities to collaborate.

Genographic Scientists on NG Weekend

"There is a lot of commonality among all of us, and it is fairly recent," says Genographic scientist Pierre Zalloua (Principal Investigator, Middle East). Pierre and Lisa Matisoo-Smith (Principal Investigator, Oceania) explain how the Genographic Project enhances our understanding of shared heritage on National Geographic Weekend radio. Tune in.

Genographic Collaboration

Genographic research finds that modern humans first migrated out of Africa via a coastal route through Arabia, rather than Egypt. Genographic Principal Investigator Jaume Bertranpetit and team member Marta Mele, along with IBM's Laxmi Parida, worked together to develop a new analytical method that traces the relationship between genetic sequences from patterns of recombination. Learn more about the research.

Frequently Asked Question

Q: I have received my results and would like to learn more about my recent ancestry. Do you have any tips for me?

A: You can explore more recent ancestry once you have received your results. Go to the bottom of your Genographic Project Results page and click on the Learn More link, and you will find directions on how to transfer your results at no extra cost to Family Tree DNA's database, which you can query for genealogical matches. Family Tree DNA (a Genographic Project partner) will ask for your GPID and personal information, which will waive your anonymity.

"Haz tu Arbol Genealogico...El Arbol mas Hermoso de la Creacion"
Por medio de la historia familiar descubrimos el árbol más hermoso de la creación: nuestro árbol genealógico. Sus numerosas raíces se remontan a la historia y sus ramas se extienden a través de la eternidad. La historia familiar es la expresión extensiva del amor eterno; nace de la abnegación y provee la oportunidad de asegurarse para siempre una unidad familiar".
(Élder J. Richard Clarke, Liahona julio de 1989, pág.69)

Los primeros colonizadores tienen más éxito al transmitir sus genes

Por Agencia EFE

Washington, 3 nov (EFE).- Una nueva investigación sobre la genealogía de los primeros pioneros humanos en Canadá indica que los pobladores que fueron los primeros en colonizar una nueva región tienen más éxito en transmitir sus genes que los colonizadores que les siguieron, según publica hoy la revista Science.

Hasta ahora, pocos estudios han explorado las consecuencias de las migraciones en el genoma del humano moderno, pero un equipo multidisciplinar ha analizado la expansión de las colonias humanas en Quebec (Canadá) entre 1686 y 1960.

Damian Labuda de la Universidad de Montreal, Lauren Excoffier de la Universidad de Berna y el Suiss Insitute of Bioinformatics, (Suiza) y Héléne Vézina de la Universidad de Québec (Canadá) han estudiado los efectos de la rápida expansión territorial y demográfica en la reciente evolución humana en esta zona.

El estudio sugiere, después de analizar más de un millón de individuos de la región Charlevoix-Saguenay Lac St-Jean, que la expansión de la población crea oportunidades para que se dé la selección natural.

Utilizando viejos registros de iglesias, los investigadores analizaron la genealogía de los habitantes y descubrieron que los pobladores que colonizaron la nueva región tuvieron significativamente más hijos que aquellos que vivieron dentro del centro o núcleo de una colonia existente.

Estos primeros colonos vivieron en la zona del ámbito de expansión llamado "frente de onda", durante la colonización de Quebec, y las mujeres en este grupo tuvieron tasas de fertilidad un 15 por ciento más altas que las que se unieron a las colonias más tarde, según los investigadores.

El estudio sugiere que puede deberse a que, en promedio, las mujeres que estaban en esa parte de los asentamientos se casaron un año antes que las mujeres que se establecieron en el núcleo de población.

El "frente de onda" es una especie de punto base desde el que los colonos empiezan a desplazarse a otras zonas y comienzan a asentarse en una región y cuando el territorio ha sido conquistado desaparece.

Dado que este éxito reproductivo solo parece ocurrir en este punto, los investigadores argumentan que la fertilidad es una característica que puede evolucionar rápidamente durante la expansión, pasando de una generación a la siguiente.

"Encontramos que las familias que están a la vanguardia de una expansión hacia un nuevo territorio tienen mayor éxito reproductivo. En otras palabras, que tenían más niños y más niños que también tenían niños", explicó Labuda.

"Como resultado, estas familias hicieron una mayor contribución genética a la población contemporánea que aquellos que se quedaron en los que llamamos el núcleo de rango, en comparación con el frente de onda", agregó.

DNA takes genealogy to next level : Technology aids family tree formation

DNA takes genealogy to next level

Technology aids family tree formation

The Salt Lake TribuneOctober 2, 2011

When they run into those inevitable brick walls in search of their ancestors, more and more genealogists are turning not to census data, military logs or death notices, they're spitting into vials.

Genetic testing can enable researchers to identify living people with whom they share common kin and figure out where in the world distant ancestral homes were and long forgotten ethnic roots.

Such testing services are widely available and steadily improving, but there are limits to what they can accomplish. To maximize its potential, Utah-based GeneTree (genetree.com) now provides counselling to help genealogical searchers determine what they can learn through genetic tests, which tests to take and who in your family can provide useful samples.

"If you get a little creative and test your mother's brother, you can extend Y chromosome into different areas in your pedigree," said Scott Woodward, chief scientific officer at the Sorenson Molecular Genealogy Foundation, which operates GeneTree. "We can help identify collateral people in your pedigree."

Bennett Greenspan, founder and president of Houston-based Family Tree DNA (familytreedna.com), estimates 90 per cent of genealogical searchers have tapped their genes, or those of a surrogate.

"The problem with genealogy, especially before the Internet, is you always run into a roadblock," Greenspan said. "This could be my surrogate piece of paper."

Greenspan, whose company was among the first in 2000 to offer genetic tests for genealogy, used genetic testing on his own pedigree to determine whether his cousin descended from someone he found in an online database who lived in a Ukrainian village and had the same surname.

The two men's Y chromosomal DNA matched up, proving what Greenspan couldn't using traditional genealogical tools such as birth and marriage certificates, census data, immigration documents and military records.

These paper resources are indispensable, but they don't always survive and are not much help for unravelling adoptions and "illegitimate" births. While records might be destroyed in a fire or a flood, DNA abides and never lies. Increasingly, genetic testing is examining autosomal DNA. Because these tests cast a much wider net, the information they yield is harder to interpret.
