This list stems from the database of Dyen et al. 1992 (see also the Dyen 1992 200) and is supposed to directly reflect the list by Swadesh 1952 200, yet the concept labels slightly differ from the original concept list. The list presents ranks for the 200 basic concepts, which are retrieved from the calculation of evolutionary rates from phylogenetic analyses on the database by Dyen et al (1992).
