Darwin's Cathedral: Evolution, Religion, and the Nature of Society
One of the great intellectual battles of modern times is between evolution and religion. Until now, they have been considered completely irreconcilable theories of origin and existence. David SloanExpand
The evolutionary basis of risky adolescent behavior: implications for science, policy, and practice.
TLDR
The evolutionary model contends that understanding the evolutionary functions of adolescence is critical to explaining why adolescents engage in risky behavior and that successful intervention depends on working with, instead of against, adolescent goals and motivations. Expand
Character Release and Displacement in Fishes: A Neglected Literature
TLDR
It is shown that competition is frequently a diversifying force that creates differences between species and differences within species when other closely related species are absent, and the lake environment can be viewed as a set of non-Hutchinsonian or "environmental" niches that exist apart from the species that occupy them. Expand
Summary of: ‘Unto Others. The evolution and psychology of unselfish behavior'
Introduction: Bentham's corpse. Part 1 Evolutionary altruism: altruism as a biological concept a unified evolutionary theory of social behaviour adaptation and multilevel selection group selectionExpand
Shy-bold continuum in pumpkinseed sunfish (Lepomis gibbosus): An ecological study of a psychological trait.
TLDR
It is shown that a shy-bold continuum, which influences diet, predator risk, and parasite fauna, exists in juvenile pumpkinseed sunfish (Lepomis gibbosus), and phenotypic stability may not reflect innate tendencies to be shy or bold but rather environmental conditions that maintain differences between phenotypically plastic individuals. Expand
Adaptive individual differences within single populations.
TLDR
A general conceptual framework for thinking about adaptive individual differences within populations can unite subjects as seemingly different as speciation and personality psychology. Expand
Rethinking the Theoretical Foundation of Sociobiology
TLDR
This article takes a “back to basics” approach, explaining what group selection is, why its rejection was regarded as so important, and how it has been revived based on a more careful formulation and subsequent research. Expand
THE EVOLUTION AND FUNCTIONS OF LAUGHTER AND HUMOR: A SYNTHETIC APPROACH
TLDR
It is hypothesized that Duchenne laughter became fully ritualized in early hominids between 4 and 2 mya as a medium for playful emotional contagion and postulate that a generalized class of nonserious social incongruity would have been a reliable indicator of such safe times and thereby came to be a potent distal elicitor of laughter and playful emotion. Expand
Functional diversity among predators of a freshwater snail imposes an adaptive trade-off for shell morphology
TLDR
The physical tests, foraging trials and field survey of the present study demonstrate the functional basis for predator-induced plasticity, which has been documented elsewhere for physid shell morphology and serves as a fourth line of support for the existence of an adaptive trade-off. Expand
