Family trees are useful in genetics and anthropology as they can trace families' geographic dispersal patterns. In order to understand human longevity and the geographic spread of families, the authors examined the pedigrees of 86 million individuals. Kaplanis et al. obtained their massive data set by collating data genealogy from Geni.com. Geni.com is a crowdsourcing genealogy website that allows users to upload their own family trees. The website also allows users to link there profiles with other users to create family trees. After cleaning and organizing the data they wound up with a pedigree of 13 million individuals. With this data set the authors found an increase of familial dispersal over time as well as a decline of genetic relatedness between couples over time. Overall, this paper represents a great step in the future of using publicly available genealogical data in research.
