Aggressiveness, Territoriality, and Sexual Behavior in Field Crickets (Orthoptera: Gryllidae)
Most contacts between adult male field crickets involve aggressive behavior by one or both individuals and terminate with the obvious retreat of one individual. Aggressive behavior consists of one orExpand
The evolution of social behavior
TLDR
For several years the study of social behavior has been undergoing a revolution with far-reaching consequences for the social and biological sciences, partly due to growing acceptance of the evidence that the potency of natural selection is overwhelmingly concentrated at levels no higher than that of the individual. Expand
The biology of moral systems
TLDR
The author argues that the ultimate interests of humans are reproductive, and that the concept of morality has arisen within groups because of its contribution to unity in the context, ultimately, of success in intergroup competition. Expand
EVOLUTIONARY CHANGE IN CRICKET ACOUSTICAL COMMUNICATION
TLDR
The reconstruction attempted here comes from evidence accumulated by the participants in this symposium, and from a comparative examination of the various stridulatory patterns of about 100 cricket species, representing eight subfamilies, 20 genera, and 30 species groups. Expand
The Biology of the Naked Mole-Rat
TLDR
An international group of researchers covers such topics as the evolution of eusociality, phylogeny and systematics of the rodent family Bathyergidae, population and behavioral ecology and genetics of naked mole-rats in the field, vocal and nonvocal behaviors, social organization and divisions of labor within colonies, and climatic, social, and physiological factors affecting growth, reproduction, and reproductive suppression.

TLDR
The tendency of various field cricket species to become double-cycled at certain latitudes appears to have resulted in speciation without geographic isolation in at least one case. Expand
