TL;DR: It is argued that inclusive fitness theory has been of little value in explained the natural world, and that it has led to negligible progress in explaining the evolution of eusociality, but these arguments are based upon a misunderstanding of evolutionary theory and a misrepresentation of the empirical literature.

TL;DR: Experiments demonstrate that immune factors have complex effects on each sex, ranging from reducing the ability of gametocytes to develop into gametes, to affecting the viability of offspring, and incorporate results into theory to predict how the evolutionary trajectories of parasite sex ratios are shaped by sex differences in gamete production, fertility and offspring development.

TL;DR: It is shown that several possible promoters of the haplodiploidy effect would have been unimportant on the route to eusociality, because they involve traits that evolved only after eussociality had become established and the level of promiscuity has a strong and consistently negative influence on selection for helping.

TL;DR: The results suggest that the transition into the nesting male tactic is accompanied both by an increase in testicular androgen production and by a higher conversion of androgens into estrogens in the brain.

TL;DR: Both T and E(2) failed to promote male-like behavior, suggesting that behavioral masculization during tactic switching depends on other neuroendocrine mechanisms or that the time length of the experiment was insufficient to induce male- like behavioral changes in sneakers.
