Guide to The Site

This site offers interactive maps and charts from the Atlas of Ancestral Genography, a database compilation of ancestral human DNA gathered from every corner of the globe. In addition to the latest haplogroup data, charted using some of the newest web graphics available, many visualizations incorporate socioeconomic and environmental footprint information as well, allowing for a unique glimpse at haplogroup genography in the light of political, economic, and ecological indicators. The interactive charts in the Atlas allow the viewer to modify views and even analyze and explore data directly within the graphic image. These visualizations take haplogroup mapping to previously unseen levels. How-to-use-this-site videos are available on YouTube.

            The organizing principle for these data is the ancestral haplogroup. If you are not familiar with the concept of haplogrouping, please read this introduction. For personal haplogroup testing, 23andme provides an inexpensive test (see link below for discounted pricing).

            The presentation here is organized in several ways. First, the data may be viewed as national data, indexed by country. Second, they are presented as ethnic data, indexed by cluster. Third, the data are viewable by gender-linked marker, indexed by haplogroup. Fourth, the data are presented according to ecosocionomic indicators, indexed by indicator. Fifth, the data are offered as a set of interactive maps that may be explored by the user. Sixth, the entire data set is available for download in a variety of file formats, allowing for scholarly use with statistical software. The entire list of visualizations is also indexed.

The rumination pages present interpretations of the genograpahic data. Any site contributor may propose new pages under this heading for presentation and discussion of ideas. The methods page explains how the data presented were assembled, compiled, calculated, and analyzed. The sources page cites each of the primary research papers providing the underlying haplogroup data, indexed according to People Cluster. The research aggregator displays the latest research in the field of genography. The headlines are active and lead to the original source materials. 

The data gaps page lists several areas where additional data is needed. For certain major people clusters Y-DNA haplogroup data has not yet been found. The Atlas asks for help in addressing these gaps. Furthermore, the Y-DNA side of the project presented here needs to be entirely reproduced for the MtDNA data. The Atlas is seeking a lead researcher to supervise this task. The Atlas also seeks individuals who are willing to adopt individual countries and to serve as data custodians for those countries. This task will involve keeping information updated and consistent with the latest primary research. Finally, several nations lack any ecological footprint data and the Atlas seeks to complete these. As the field of genography matures, there may be other types of data to be layered into what we already have. Please contact the site administrator for more information and offers of assistance:

It is my hope that the world community of scholars and amateurs who follow this field will find the Atlas a convenient concentration of data and will contribute some of their time to the understanding, perpetuation, expansion, and improvement of the Atlas.
