Major Hurdles for the Evolution of Sociality
Judith Korb,Jürgen Heinze +1 more
TL;DR: Here, concepts and theories in social evolution are synthesized and the evolution of helping is shaped by direct and indirect fitness options and helping is only altruism if it reduces the helper's direct fitness.

Very low levels of direct additive genetic variance in fitness and fitness components in a red squirrel population
S. Eryn McFarlane,Jamieson C. Gorrell,David W. Coltman,Murray M. Humphries,Stan Boutin,Andrew G. McAdam +5 more
TL;DR: It appears that there are very low levels of direct genetic variance in fitness and fitness components in red squirrels to facilitate contemporary adaptation in this population.
Journal ArticleDOI
Reactive strategies in indirect reciprocity.
TL;DR: All of the reactive strategies that are stochastic, including deterministic ones as special cases, are investigated, and it is found that only the mean 'discriminatoriness' in the population is the parameter that affects the evolutionary dynamics.
Journal ArticleDOI
An exact form of the breeder's equation for the evolution of a quantitative trait under natural selection.
TL;DR: It is shown that all five components of phenotypic evolution will generally have nonzero values as a result of various combinations of the normal features of Mendelian populations, including biparental sex, allelic dominance, inbreeding, epistasis, linkage disequilibrium, and environmental covariances between traits.

Multilevel selection with kin and non-kin groups, experimental results with Japanese quail (Coturnix japonica).
TL;DR: In terms of a sustainability of breeding programs, multilevel selection is easy to implement and is expected to give near optimal responses with reduced rates of inbreeding as compared to group selection, the only requirement is that animals be housed in kin groups.
