This dataset and associated phylogeny describes brain weights, body weights, dietary categories, social systems, mating systems, and group sizes for 143 primate species. These data were originally compiled in DeCasien et al. (2017). The phylogeny is a 50% majority rule consensus tree from the 10k Trees website.
primatesA list containing a dataset and an associated phylogeny. The phylogeny is a pruned consensus tree for 143 species of primate (excluding humans). The dataset is a data frame with 143 observations and 11 variables:
The primate species
The clade of the primate species
Average brain weight, in grams
Average body weight, in grams
A factor with four levels indicating whether the species' dietary category is folivore, frugivore, frugivore/folivore, or omnivore
Percentage of fruit in diet
A factor with four levels indicating whether the species' social system is solitary, pair-living, harem polygyny, or polygynandry
A factor with five levels indicating whether the species' mating system is spatial polygyny, monogamy, polyandry, harem polygyny, or polygynandry
Average group size
