Mean and Standard error (S.E.) of the Bayes Factor tests (n = 20) comparing the harmonic mean of the likelihoods of the Bayesian ancestral state reconstruction analyses with the common ancestor of corbiculates alternatively fixed as being solitary, social, primitively eusocial, advanced eusocial, a

Sol: Solitary.
Prim: Primitively eusocial.
Soc: Social.
Adv: Advanced eusocial.
Par: Parasitic.
*Bayes Factor test strongly supports a primitively eusocial ancestor over the other state (i.e. Bayes Factor >5 [34]).
