The WHIPPO-1 Dataset


John Gatesy and his colleagues (1999) compiled 17 data sets to examine the phylogenetic relationships between Artiodactyla (even-toed ungulates) and Cetacea (whales). The datasets include molecular sequences, other molecular characters and morphological data. They include representatives of 13 taxonomic groups. While each taxon is not represented in each dataset, the data sets all include representatives from each of the four major clades of extant artiodactyls. The primary goal of this analysis was to look at the phylogenetic position of the Cetacea with respect to the Artiodactyl groups. This data provides a rich resource for looking closely at the use of multiple sources of data for establishing phylogenetic hypotheses.
