Evolutionary Models of Music: From Sexual Selection to Group Selection
TL;DR: The authors argue that music and group rituals co-evolved during human evolution such that ritual developed as an information system and music its reinforcement system, and music is a type of social reward system analogous to the neuromodulatory systems of the brain.
Journal ArticleDOI
The group selection controversy.
TL;DR: To grasp fully how cooperation and altruism evolve, most biologists need more concrete concepts like kin selection, group selection and selection among individuals for their common good.

The consistency of individual differences in behaviour: temperature effects on antipredator behaviour in garter snakes
TL;DR: Temperature had substantial effects on the average expression of each behaviour; snakes crawled more slowly, for shorter distances, and performed fewer reversals at cooler temperatures, while individuals showed significant consistency in their behaviour, and this consistency of expression was not affected by temperature.

Heritability, covariation and natural selection on 24 traits of common evening primrose (Oenothera biennis) from a field experiment.
TL;DR: The combination of genetic covariances and directional selection acting on multiple traits suggests that adaptive evolution of particular traits is constrained, and that correlated evolution of groups of traits will occur, which is expected to drive the evolution of increased herbivore susceptibility.

TL;DR: Although the BE predicts increasing size, the STS does not, which is a discrepancy that suggests unmeasured factors are upwardly biasing the authors' estimates of selection on phenotype, and it is suggested wider application of theSTS could offer at least a partial resolution to the common discrepancy between naive expectations and observed trait dynamics in natural populations.
