Relatedness and inclusive fitness with inbreeding.
TL;DR: General inclusive fitness formulations of kin selection models based on a variable of relatedness taking as values two pedigree indices in populations with inbreeding when selection is weak are proposed.

Evolutionary transitions in heritability and individuality
TL;DR: A highly idealized model is presented to study the relationship between particle-level and collective- level heritability both when a collective-level trait is a linear function and when it is a nonlinear function of a particle- level trait.

Evolutionary stasis of a heritable morphological trait in a wild fish population despite apparent directional selection

TL;DR: Direction selection for larger female size in Atlantic salmon is documented, using pedigree‐derived estimates of lifetime reproductive success as a fitness measure and it is shown the trait is heritable and, thus, capable of responding to selection.

Defector clustering is linked to cooperation in a pathogenic bacterium.
TL;DR: Competing siderophore-producing cooperator and defector strains of the opportunistic pathogen Pseudomonas aeruginosa in experimental microhabitats found that at the spatial scale of individual interactions, cooperator clustering lowers cooperation, but defector clustering favours cooperation.

Cultural selection and biased transformation: two dynamics of cultural evolution.
TL;DR: The authors discusses two broad versions of human cultural evolution which currently exist in the literature and which emphasize different underlying dynamics, including cultural selection and biased transformation, and concludes that cultural evolution is characterized by one or the other of these dynamics.
