“…This approach can be extended to more complex cases, including so-called emergent traits that cannot be observed on a single individual, as illustrated by examples in Wilson et al (2011) and Bijma (2011); see also Linksvayer et al (2012) and Bailey (2012).…”

“…In natural populations, in contrast, the potential impact of IGEs for response to selection seems almost unlimited because the social organisation of the population is itself evolving. At present, models including IGEs are finding widespread application in natural populations, which may considerably broaden our quantitative genetic understanding of evolution by natural selection (Bailey, 2012). Examples are the impact of IGEs on the evolution of social interactions due to sexual selection (Chenoweth et al, 2010;Bailey and Moore, 2012) and the extension of gene networks to societies (Linksvayer et al, 2012).…”

The quantitative genetics of indirect genetic effects: a selective review of modelling issues

Indirect genetic effects (IGE) occur when the genotype of an individual affects the phenotypic trait value of another conspecific individual. IGEs can have profound effects on both the magnitude and the direction of response to selection. Models of inheritance and response to selection in traits subject to IGEs have been developed within two frameworks; a trait-based framework in which IGEs are specified as a direct consequence of individual trait values, and a variance-component framework in which phenotypic variance is decomposed into a direct and an indirect additive genetic component. This work is a selective review of the quantitative genetics of traits affected by IGEs, with a focus on modelling, estimation and interpretation issues. It includes a discussion on variance-component vs trait-based models of IGEs, a review of issues related to the estimation of IGEs from field data, including the estimation of the interaction coefficient W (psi), and a discussion on the relevance of IGEs for response to selection in cases where the strength of interaction varies among pairs of individuals. An investigation of the trait-based model shows that the interaction coefficient W may deviate considerably from the corresponding regression coefficient when feedback occurs. The increasing research effort devoted to IGEs suggests that they are a widespread phenomenon, probably particularly in natural populations and plants. Further work in this field should considerably broaden our understanding of the quantitative genetics of inheritance and response to selection in relation to the social organisation of populations.

“…Today we call such a process niche construction, but the new name does not alter the fact that evolutionary biologists have been studying feedback between organisms and the environment for well over a century 13 . Stunning adaptations such as termite mounds, beaver dams, and bowerbird displays have long been a staple of evolutionary studies.…”

“…Under the extended fitness hypothesis, selection would favor groups that develop extended phenotypes that only their members can use. The horn-shaped subterranean burrows built by male mole crickets are extended phenotypes that are species-specific (Bailey, 2012). The morphology of oak galls built by gallwasps in their oak hosts is also species-specific (Bailey et al, 2009).…”

Short Communication "Extended Fitness" hypothesis: a link between individual and group selection

ABSTRACT.What are the targets of natural selection remains a controversial issue in Biology. Here I propose the "Extended Fitness" hypothesis, in which extended phenotypes emerge as a link between individual and group selection. The basic premise of the extended fitness hypothesis is that extended phenotypes can be used by members of the same group since they are adapted to use them. Thus, extended phenotypes can also contribute to the fitness of members of the same species. Group selection emerges as a natural consequence of the shared use of extended phenotypes, which allow the evolutionary forces acting on individuals to become effective at the group level. The extended fitness hypothesis is supported by several observations found in nature. The hypothesis presented here provides a theoretical framework for the design of both modeling and experimental approaches to studying the role of extended phenotypes in group selection.
