Nicolas Claidière and Dan Sperber - Imitation explains the propagation, not the stability of animal culture (2008) - Proceedings of the Royal Society B, Biological Sciences
For acquired behaviour to count as cultural, two conditions must be met: it must propagate in a social group, and it must remain stable across generations in the process of propagation. It is commonly assumed that imitation is the mechanism that explains both the spread of animal culture and its stability. We review the literature on transmission chain studies in chimpanzees (Pan troglodytes) and other animals, and we use a formal model to argue that imitation, which may well play a major role in the propagation of animal culture, cannot be considered faithful enough to explain its stability. We consider the contribution that other psychological and ecological factors might make to the stability of animal culture observed in the wild. -- Keywords: imitation, cultural evolution, animal culture -- See addendum commentary "The natural selection of fidelity in social learning" in Commun Integr Biol, volume 3 (2010) -- Both downloaded to Tab S2

Krasnow et al - Group Cooperation without Group Selection: Modest Punishment Can Recruit Much Cooperation, PLoS ONE (April 2015) | via Researchgate
Max M Krasnow, Andrew W Delton, Leda Cosmides, John Tooby -- PLoS ONE 04/2015; 10(4):e0124561. DOI: 10.1371/journal.pone.0124561 (Impact Factor: 3.23). -- ABSTRACT -- Humans everywhere cooperate in groups to achieve benefits not attainable by individuals. Individual effort is often not automatically tied to a proportionate share of group benefits. This decoupling allows for free-riding, a strategy that (absent countermeasures) outcompetes cooperation. Empirically and formally, punishment potentially solves the evolutionary puzzle of group cooperation. Nevertheless, standard analyses appear to show that punishment alone is insufficient, because second-order free riders (those who cooperate but do not punish) can be shown to outcompete punishers. Consequently, many have concluded that other processes, such as cultural or genetic group selection, are required. Here, we present a series of agent-based simulations that show that group cooperation sustained by punishment easily evolves by individual selection when you introduce into standard models more biologically plausible assumptions about the social ecology and psychology of ancestral humans. -- downloaded pdf to Note

Inclusive fitness theory and eusociality, Nature, 2011 - Everybody & his cousins reckoned by the dozens defending the theory | via Researchgate
Nature, 03/2011; 471(7339):E1-4; author reply E9-10. DOI: 10.1038/nature09831 (Impact Factor: 41.46). STRATOSOHERIC IMPACT, 100+ cites, so see Researchgate for bibliography -- Source: PubMed -- ABSTRACT -- Arising from M. A. Nowak, C. E. Tarnita & E. O. Wilson 466, 1057-1062 (2010); Nowak et al. reply. Nowak et al. argue that inclusive fitness theory has been of little value in explaining the natural world, and that it has led to negligible progress in explaining the evolution of eusociality. However, we believe that their arguments are based upon a misunderstanding of evolutionary theory and a misrepresentation of the empirical literature. We will focus our comments on three general issues. -- downloaded pdf to Note

Todd K Shackelford and James R Liddle - An overview of evolutionary psychology, Wiley interdisciplinary reviews. Cognitive science (2014) | via Researchgate
Understanding the mind from an evolutionary perspective: An overview of evolutionary psychology, Wiley interdisciplinary reviews. Cognitive science, 05/2014; 5(3). DOI: 10.1002/wcs.1281 (Impact Factor: 0.79). -- ABSTRACT --
The theory of evolution by natural selection provides the only scientific explanation for the existence of complex adaptations. The design features of the brain, like any organ, are the result of selection pressures operating over deep time. Evolutionary psychology posits that the human brain comprises a multitude of evolved psychological mechanisms, adaptations to specific and recurrent problems of survival and reproduction faced over human evolutionary history. Although some mistakenly view evolutionary psychology as promoting genetic determinism, evolutionary psychologists appreciate and emphasize the interactions between genes and environments. This approach to psychology has led to a richer understanding of a variety of psychological phenomena, and has provided a powerful foundation for generating novel hypotheses. Critics argue that evolutionary psychologists resort to storytelling, but as with any branch of science, empirical testing is a vital component of the field, with hypotheses standing or falling with the weight of the evidence. Evolutionary psychology is uniquely suited to provide a unifying theoretical framework for the disparate subdisciplines of psychology. An evolutionary perspective has provided insights into several subdisciplines of psychology, while simultaneously demonstrating the arbitrary nature of dividing psychological science into such subdisciplines. Evolutionary psychologists have amassed a substantial empirical and theoretical literature, but as a relatively new approach to psychology, many questions remain, with several promising directions for future research.

Melissa Emery Thompson and Alexander V Georgiev - Issue Intro - High Price of Success: Costs of Mating Effort in Male Primates, International Journal of Primatology (2014) | via Researchgate
Melissa Emery Thompson, U of New Mexico, and Alexander V Georgiev, U of Chicago -- Issue Intro -- International Journal of Primatology, 08/2014; DOI: 10.1007/s10764-014-9790-4 (Impact Factor: 1.99). -- ABSTRACT
While males are generally the low investing sex when it comes to offspring care, males of many species experience intense and persistent mating effort. Mating effort incurs a variety of costs which are expected to have non-negligible effects on fitness, as well as how reproductive tactics are selected and investment in mating activity is moderated over time. This special issue features contributions investigating the costs of male mating effort across primate species. Here, we place these exciting new works in context, addressing the specific types of mating effort expected for male primates and the significance of these costs for our understanding of primate life histories and socioecology. -- downloaded pdf to Note

Jonathan Kaplan - The end of the Adaptive Landscape metaphor?, Biology and Philosophy (2008) | via Researchgate
Biology and Philosophy (Impact Factor: 1.19). 11/2008; 23(5):625-638. DOI: 10.1007/s10539-008-9116-z -- ABSTRACT -- The concepts of adaptive/fitness landscapes and adaptive peaks are a central part of much of contemporary evolutionary biology;the concepts are introduced in introductory texts, developed in more detail in graduate-level treatments, and are used extensively in papers published in the major journals in the field. The appeal of visualizing the process of evolution in terms of the movement of populations on such landscapes is very strong; as one becomes familiar with the metaphor, one often develops the feeling that it is possible to gain deep insights into evolution by thinking about the movement of populations on landscapes consisting of adaptive valleys and peaks. But, since Wright first introduced the metaphor in 1932, the metaphor has been the subject of persistent confusion, from equivocation over just what the features of the landscape are meant to represent to how we ought to expect the landscapes to look. Recent advances—conceptual, empirical, and computational—have pointed towards the inadequacy and indeed incoherence of the landscapes as usually pictured. I argue that attempts to reform the metaphor are misguided; it is time to give up the pictorial metaphor of the landscape entirely and rely instead on the results of formal modeling, however difficult such results are to understand in ‘intuitive’ terms. -- downloaded pdf to Note
