about

In this book, Ito presents data on tropical wasps which suggest that kin-selection has been overemphasized as an evolutionary explanation of sociality. He concentrates on the Vespidae (paper wasps and hornets), a group much discussed by evolutionary biologists because it exhibits all stages ofsocial evolution: subsociality, primitive eusociality, and advanced eusociality. The author reports field observations by himself and others in Central America, Asia, and Australia, showing that multiple egg-layers in a nest are not uncommon. Because coexistence of many 'queens' leads to lowerrelatedness among colony members than in single-queen colonies, he suggests that kin-selection may not be the most powerful force determining observed social patterns. Instead, subsocial wasps may first have aggregated for defense purposes in habitats with a high risk of predation, with mutualisticassociations among many queens. Through parental manipulation and then kin selection, differentiation into within-generatio

`This book beautifully illustrates the ability to combine wide-ranging data with thoughtful questions. It offers a basis for further research in this respect, but is also of general interest to all students of ecology, evolution and behaviour.'Entomologia Generalis, Vol. 22 No. 1
