Many animals regulate their population density by patterns of behavior that would be easy to explain if the forces of natural selection acted to optimize group properties. But Darwinian selection acts on individuals, not groups, and most simple theories have shown group selection to be too slow ever to oppose individual selection successfully.In this book Michael Gilpin presents a model, based on predator-prey dynamics, wherein nonlinear effects are important, so that small advantages to the selfish individual are nonlinearly amplified into disaster for his group. The result is that group selection can be rapid and powerful. Of course many instances of apparent group selection can be explained by kin selection; in other cases, close examination reveals that seemingly altruistic behavior directly benefits the individual genotype as well as the group. The value of the monograph is that it provides a robust model in which group selection, pure and unadulterated, can be seen to work.

How the urban spectator became the archetypal modern viewer and a central subject in late nineteenth-century French artGawkers explores how artists and writers in late nineteenth-century Paris represented the seductions, horrors, and banalities of street life through the eyes of curious viewers known as badauds. In contrast to the singular and aloof bourgeois flâneur, badauds were passive, collective, instinctive, and highly impressionable. Above all, they were visual, captivated by the sights of everyday life. Beautifully illustrated and drawing on a wealth of new research, Gawkers excavates badauds as a subject of deep significance in late nineteenth-century French culture, as a motif in works of art, and as a conflicted model of the modern viewer.Bridget Alsdorf examines the work of painters, printmakers, and filmmakers who made badauds their artistic subject, including Félix Vallotton, Pierre Bonnard, Henri de Toulouse-Lautrec, Honoré Daumier, Edgar Degas, Jean-Léon Gérôme, Eugène Carrière, Charles Angrand, and Auguste and Louise Lumière. From morally and intellectually empty to sensitive, empathetic, and humane, the gawkers these artists portrayed cut across social categories. They invite the viewer’s identification, even as they appear to threaten social responsibility and the integrity of art.Delving into the ubiquity of a figure that has largely eluded attention, idling on the margins of culture and current events, Gawkers traces the emergence of social and aesthetic problems that are still with us today.
