Abstract
Our phylogenetic comparative analysis to test the predictions of the superorganismal anisogamy model involved three steps: i) collecting data on queen and male ant sizes from digital museum images; ii) collecting data on colony size, worker caste number, and queen number for as many of these species as possible from published databases; iii) building statistical models to determine the effects of colony size, worker caste number, queen number, and their interactions, on the evolution of queen size and queen-male dimorphism.

Description: This CSV document contains raw data for the phylogenetic comparative analysis
Column descriptions:
A. subfamily = the ant subfamily to which each species belongs
B. tip_label = the Latin binomial of each species, matches the phylogeny
C. male_MW = maximum mesosoma width for the male of each species
D. male_ML = maximum mesosoma length for the male of each species
E. queen_MW = maximum mesosoma width for the queen of each species
F. queen_ML = maximum mesosoma width for the queen of each species
G. colony_size = number of workers in mature colonies
H. queen_number_continuous = average number of queens observed per colony
I. caste_number = binary number of worker castes (one or more than one caste)
File: Table_S2.csv
Description: This CSV document contains results from the statistical analyses using an inverse Gamma prior
column descriptions:
A. Fixed terms = the predictor variable(s) used in each model
B. parameter = name of the parameter estimate
C. estimate = value of the parameter estimate
D. Lwr CI = lower 95% credible interval of the parameter estimate
E. Upr CI = upper 95% credible interval of the parameter estimate
F. Phylogenetic H2 = the proportion of variance explained by phylogeny

Description: The R script contains all the code needed to replicate the comparative analyses
Note that these analyses can take multiple days to run.
