TL;DR: It is demonstrated that cooperative breeding is associated with low promiscuity; that in cooperative species, helping is more common when Promiscuity is low; and that intermediate levels of promiscity favour kin discrimination, which suggests that promiscuit is a unifying feature across taxa in explaining transitions to and from cooperative societies.

TL;DR: It is argued that a move from purely gene-focused theories of sexual selection towards research that explicitly integrates development, ecology and evolution is necessary to break the stasis in research on sexual traits.

TL;DR: The results indicate that female promiscuity leads to the evolution of sophisticated male sexual behaviour in birds, and male sperm allocation of unprecedented sophistication in the fowl Gallus gallus is demonstrated.

TL;DR: The results conflict with the conventional view that coexistence promotes trait divergence among co-occurring organisms at macroevolutionary scales, and instead provide evidence that species interactions can drive phenotypic convergence across entire radiations, a pattern generally concealed by biases in age.

TL;DR: Both transmission mode and symbiont function are correlated with host dependence, with reductions in host fitness being greatest when nutrient-provisioning, vertically transmitted symbionts are removed and results suggest that both function and population structure are important in driving irreversible dependence between hosts and symbions.
