Journal ArticleDOI
Variation in the strength and softness of selection on deleterious mutations.
TL;DR: It is shown that the softness of selection is not determined by ecological conditions alone, and that wild‐type individuals tend to benefit more than mutants from being reared with competitors of low genetic quality.
Journal ArticleDOI
Evolution of helping and harming in viscous populations when group size varies.
TL;DR: It is found that spatial and temporal heterogeneity in individual fecundity may interact with patch-size heterogeneity to change these predictions, promoting the evolution of harming in big patches and of helping in little patches.
Journal ArticleDOI
Social selection and the evolution of cooperative groups: the example of the cellular slime moulds
TL;DR: A possible route to the evolution of social groups that involves many steps: individuals that happen to be in spatial proximity benefit simply by virtue of their number; traits that are already present act as preadaptations and improve the efficiency of the group; and new adaptations evolve under selection in the social context--that is, via interactions between individuals--and further strengthen group behaviour.

The major transitions in the evolution of language
TL;DR: The main challenges in evolutionary linguistics are to explain how three major linguistic innovations could have spread through a population where they are initially rare, and how universal properties and tendencies in natural languages can result from the intricate interaction between innate learning biases and a process of cultural evolution over many generations.
Journal ArticleDOI
Joint phenotypes, evolutionary conflict and the fundamental theorem of natural selection.
TL;DR: The evolution of joint phenotypes in quantitative genetic terms is described, where a joint phenotype for multiple species evolves as the sum of additive genetic variances in each species, weighted by the selection on each species.
