Hierarchical selection theory and sex ratios. ii. on applying the theory, and a test with fig wasps.
TL;DR: Observations strongly support the qualitative prediction that fig wasp sex ratios (males/total) decrease with increasing amounts of both inbreeding and competition among male relatives for access to mates, but the observed sex ratio is consistently lower than predicted by previous quantitative models.

Interpreting the 'selection effect' of biodiversity on ecosystem function
TL;DR: Using the Price Equation, it is shown that the ‘selection effect’ only partially reflects dominance by species with particular traits at the expense of other species, and therefore is only partially analogous to natural selection.

On Modeling Cognition and Culture: Why cultural evolution does not require replication of representations
Joseph Henrich,Robert Boyd +1 more
TL;DR: Three formal models are used to show that very low fidelity replication of representations at the individual level does not preclude accurate replication at the population level, and therefore, accurate individual-level replication is not necessary for either cultural inertia or cumulative cultural adaptation.

The Schema Theorem and Price's Theorem
TL;DR: Dissenting arguments are reviewed and elaborated upon, explaining why the Schema Theorem has no implications for how well a GA is performing, and an alternative statistic is proposed as the optimal statistic for estimating GA performance from limited samples.

The Evolution of Strong Reciprocity: Cooperation in Heterogeneous Populations
TL;DR: In this paper, the authors suggest that many humans have a predisposition to punish those who violate group-beneficial norms, even when this imposes a fitness cost on the punisher.
