Social runaway: Fisherian elaboration (or reduction) of socially selected traits via indirect genetic effects Our understanding of the evolutionary stability of socially-selected traits is dominated by sexual selection models originating with R. A. Fisher, in which genetic covariance arising through assortative mating can trigger exponential, runaway trait evolution. To examine whether non- reproductive, socially-selected traits experience similar dynamics—social runaway—when assortative mating does not automatically generate a covariance, we modelled the evolution of socially-selected badge and donation phenotypes incorporating indirect genetic effects (IGEs) arising from the social environment. -

Reading: Masters of Light: the Science Behind Nature's Brightest
Masters of Light: The Science Behind Nature’s Brightest Colors JULIA ROTHCHILD DECEMBER 30, 2014 0 In the sands of the Yukon Territory in Canada, a scientist found a beetle embedded with nano-scale diamonds. The insect was a small, brown member of the weevil family. It was plated with hollow scales, inside each of which expanses of nano-crystals had grown. Every diamond was placed exactly the same distance apart, yielding a formidably regular array that extended up and down and side to side, filling the insides of the beetle’s scales with a rigid, repeating matrix. The insect unearthed in the Yukon sand had been preserved for over half a million years as a fossil. Yale researchers inspected the preserved material using high energy X-rays at Argonne National Laboratory in Chicago in order to study the configuration of crystals. Although the structures they discovered are especially beautiful and intriguing, diamond-filled scales are not unique: many creatures alive today grow identical or similar nano-size arrays. Animals grow these sorts of structures because they are optical powerhouses. By manipulating light, the crystals allow animals to produce brilliant colors that are otherwise unattainable. Making Blue Consider the color blue. There are no blue bears in the world. There are no blue crocodiles either. There are also no blue kangaroos, blue bumblebees, blue cats, or blue dogs. There aren’t very many blue animals in the world, period, because blue is a difficult color to make. Most of the other colors of the rainbow arise straightforwardly in nature from chemicals, called pigments, that animals collect in their skin, feathers, and hair. -

Recent milestone anniversaries of Darwin's birth and of the Subscribe publication of On the Origin of Species have prompted a plethora of material, so authors thinking of adding another volume had better have a good excuse for it. We have written another book about Darwinism, and we urge you to take it to heart. Our excuse is in the title: What Darwin Got Wrong. Much of the vast neo-Darwinian literature is distressingly uncritical. The possibility that anything is seriously amiss with Darwin's account of evolution is hardly considered. Such dissent as there is often relies on theistic premises which Darwinists rightly say have no place in the evaluation of scientific theories. So onlookers are left with the impression that there is little or nothing about Darwin's theory to which a scientific naturalist could reasonably object. -
Interspecific Social Dominance Mimicry in Birds
bs_bs_banner Zoological Journal of the Linnean Society, 2014. With 6 figures Interspecific social dominance mimicry in birds RICHARD OWEN PRUM1,2* 1Department of Ecology and Evolutionary Biology, Yale University, New Haven, CT 06520-8150, USA 2Peabody Natural History Museum, Yale University, New Haven, CT 06520-8150, USA Received 3 May 2014; revised 17 June 2014; accepted for publication 21 July 2014 Interspecific social dominance mimicry (ISDM) is a proposed form of social parasitism in which a subordinate species evolves to mimic and deceive a dominant ecological competitor in order to avoid attack by the dominant, model species. The evolutionary plausibility of ISDM has been established previously by the Hairy-Downy game (Prum & Samuelson). Psychophysical models of avian visual acuity support the plausibility of visual ISDM at distances ∼>2–3 m for non-raptorial birds, and ∼>20 m for raptors. Fifty phylogenetically independent examples of avian ISDM involving 60 model and 93 mimic species, subspecies, and morphs from 30 families are proposed and reviewed. Patterns of size differences, phylogeny, and coevolutionary radiation generally support the predic- tions of ISDM. Mimics average 56–58% of the body mass of the proposed model species. Mimics may achieve a large potential deceptive social advantage with <20% reduction in linear body size, which is well within the range of plausible, visual size confusion. Several, multispecies mimicry complexes are proposed (e.g. kiskadee- type flycatchers) which may coevolve through hierarchical variation in the deceptive benefits, similar to Müllerian mimicry. ISDM in birds should be tested further with phylogenetic, ecological, and experimental investigations of convergent similarity in appearance, ecological competition, and aggressive social interactions between sympatric species. -
The Evolution of Sexual Dimorphism: Understanding Mechanisms of Sexual Shape Differences
Chapter 1 The Evolution of Sexual Dimorphism: Understanding Mechanisms of Sexual Shape Differences Chelsea M. Berns Additional information is available at the end of the chapter http://dx.doi.org/10.5772/55154 1. Introduction Understanding the origin of biodiversity has been a major focus in evolutionary and ecological biology for well over a century and several patterns and mechanisms have been proposed to explain this diversity. Particularly intriguing is the pattern of sexual dimorphism, in which males and females of the same species differ in some trait. Sexual dimorphism (SD) is a pattern that is seen throughout the animal kingdom and is exhibited in a myriad of ways. For example, differences between the sexes in coloration are common in many organisms [1] ranging from poeciliid fishes [2] to dragon flies [3] to eclectus parrots (see Figure 1). A B Figure 1.

Many species also exhibit sexual differences in foraging behavior such as the Russian agamid lizard [7], and parental behavior and territoriality can be dimorphic in species such as hummingbirds [8, 9]. -

Kin Selection and Sexual Selection
Downloaded from rstb.royalsocietypublishing.org on July 16, 2012 Phil. Trans. R. Soc. B (2012) 367, 2314–2323 doi:10.1098/rstb.2011.0281 Review The sociobiology of sex: inclusive fitness consequences of inter-sexual interactions Tommaso Pizzari1,* and Andy Gardner2,3 1Edward Grey Institute, Department of Zoology and 2Department of Zoology, University of Oxford, South Parks Road, Oxford OX1 3PS, UK 3Balliol College, University of Oxford, Broad St., Oxford OX1 3BJ, UK The diversity of social interactions between sexual partners has long captivated biologists, and its evolution has been interpreted largely in terms of ‘direct fitness’ pay-offs to partners and their des- cendants. Inter-sexual interactions also have ‘indirect effects’ by affecting the fitness of relatives, with important consequences for inclusive fitness. However, inclusive fitness arguments have received limited consideration in this context, and definitions of ‘direct’ and ‘indirect’ fitness effects in this field are often inconsistent with those of inclusive fitness theory. Here, we use a sociobiology approach based on inclusive fitness theory to distinguish between direct and indirect fitness effects. We first consider direct effects: we review how competition leads to sexual conflict, and discuss the conditions under which repression of competition fosters sexual mutualism. We then clarify indirect effects, and show that greenbeard effects, kin recognition and population viscosity can all lead to episodes of indirect selection on sexual interactions creating potential for sexual altruism and spite. We argue that the integration of direct and indirect fitness effects within a sociobiology approach enables us to consider a more diverse spectrum of evolutionary outcomes of sexual interactions, and may help resolving current debates over sexual selection and sexual conflict. -

CHARLES DARWIN AND IDEOLOGY RETHINKING THE DARWINIAN REVOLUTION JANET BROWNE This short paper critiques the idea of any coherent Darwinian ideology. Charles Darwin himself did not adopt any obvious ideology, except perhaps that of anti-slavery. However, his published work, and that of other evolutionists, led to the emergence of social Darwinism. Herbert Spencer’s role in fostering social Darwinism, and the rise of eugenics, are briefly described. The connection, if any, between the historical figure of Darwin and the social movement that bears his name is discussed. While Darwin’s On the origin of species or The descent of man can hardly account for all the racial stereotyping, nationalism, or political bigotry seen in the half century after his death, there can be no denying the impact of his work in providing an authoritative biological backing for eugenics, colonial belligerence, and western notions of racial superiority.
