Exploring The National Genographic Project

By Ronald Watson


The National Genographic Society often hosts a number of projects and studies. Currently, the National Genographic Project is in phase 2.0 Next Generation. The project is aimed at studying and mapping migration patterns of humans by analyzing and collecting DNA samples. With over 140 countries having joined as of 2018, there are now approximately one-million participants which have joined the study.

Created by Spencer Wells in April of 2005 as a non-profit partnership between the National Geographic Society and the Waitt Foundation, the studies and trials are still ongoing and most likely will continue for quite some time. The organization, being a non-profit, received funding for the project through private donations. Once enough funding was available, DNA samples were collected from different cultures and populations.

In Autumn of 2012, the project received a new array with which to use in genotyping. The array is dedicated to the study of genetic anthropology and has been provided the name of GenoChip. Designed specifically as a tool for genotyping, the array has the capability of testing a multitude of DNA types.

A second new chip was introduced in 2015 in which Genographic Lead Scientists, Vilar and Family Tree joined forces. In addition, a test known as Admixture was developed by Wells and Elhaik which works to classify individuals based on an assessment of genomic ancestral factors related to different regions of the world. Between the new chips and this new test, the society has made a great deal more progress when it comes to testing and sorting different types of DNA.

The society began using Helix DNA sequencing for the first time in Geno 2.0 Next Generation. Unlike earlier phases, the current phase is focused on analyzing populations based on modern day demographics using between eighteen and twenty-two populations. By collecting DNA samples from these groups, Helix acquires samples of saliva from participants which is then analyzed for genetic and genomic markers.

Since the beginning, volunteers have been participating by providing DNA samples along with participating in citizen scientific projects. The Genographic Society now sells non-profit self-testing kits to members of the public whom wish to participate as citizen scientists. As a method of outreach to the general public, participation has often been encouraged by a number of genealogical organizations which are seeking to promote benefits from different research programs and scientific research.

The society has used the latest technology related to genetic and DNA testing since the beginning phase in 2015. In doing so, the organization hopes to expand knowledge of the overall human story and the connection between various populations. As such, Geno 2.0 expands the scope by harnessing the power of larger populations to discover new information about the history of human populations.

While researchers have been successful in collecting a number of DNA samples, there has also been criticism, most notably by the Indigenous People's Council on Biocolonialism. For, it appears that some Native American tribes are concerned that DNA tests have the potential to incorrectly identify tribal members as not being indigenous to North America. As a result, not only have some Native Americans refused to provide DNA samples, many have also been boycotting corporations associated with the study including IBM and Gateway.
