Human history in one click: For the first time, numerous sites relating to the early history of mankind from 3 million to 20,000 years ago can be accessed in a large-scale database.
Scientists from the research center ROCEEH (The Role of Culture in Early Expansions of Humans) have compiled information on 2,400 prehistoric sites and 24,000 assemblages from more than 100 ancient cultures. The digital data collection is available for free and was published in the journal PLoS ONE.
The research center is located at the University of Tübingen and the Senckenberg Society for Nature Research.
ROAD (ROCEEH Out of Africa Database) represents one of the largest digital collections of information about archaeology, anthropology, paleontology and botany based on 150 years of research history, says Dr. Andrew Kandel, University of Tübingen. By joining information about cultural remains, human fossils, animal bones and plants into a unified geographical and chronological framework, the team created a tool that helps analyze the complex aspects of human evolution.
Since 2008 an international team of six scientists and dozens of research assistants painstakingly compiled the data. More than 5,000 publications in multiple languages were analyzed, including Chinese, Russian, English, German, French, Italian, Spanish and Portuguese.
An easy-to-use map interface shows the distribution of sites across the globe. It also allows users to graphically present the results of simple queries, so a user can make their own map by selecting a specific culture, period or region of interest. In addition, a user can also download a PDF "ROAD Summary Data Sheet" containing a site summary.
The majority of the prehistoric world remains uncharted, as shown by the blank areas. This visualization is based on a Kernel Density Estimate of assemblages in ROAD. Sites with higher densities of assemblages appear more intense in color.

ROCEEH designed ROAD to better understand the deep history of our human past. "We examine the multi-faceted relationship between culture and environment and observe its impact on human expansions." In the spirit of open science, the team makes this data freely available to the general public, students, and researchers across the globe.
The collection of these data has already shown that much of the scientific knowledge about our past comes from just a few, very well studied regions such as Southern and Eastern Africa and Europe, as well as Central and East Asia. However, Oceania was not part of the study. The blank spots hint at the expectation of exciting future discoveries about our species' past from the fields of archaeology and anthropology.
