Delivery time is estimated on our previous experiences. We give estimations only, because we order from outside Hungary, and the delivery time mainly depends on how quickly the publisher supplies the book. Faster or slower deliveries both happen, but we do our best to supply as quickly as possible.

Long description:
In this book, Itô 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 of social 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 lower relatedness 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 defence purposes in habitats with a high risk of predation, with mutualistic associations among many queens. Through parental manipulation and then kin selection, differentiation into within-generation castes may have followed.
Of interest to all students of ecology, evolution, and behaviour, this book beautifully illustrates the ability to combine wide-ranging data with thoughtful questions - the author's trademark.
'Ito is a wasp enthusiast and this book will be chiefly enjoyed by entomologists. He does not present major new ideas, but the book's strength is the careful experimental account of many years' study of paper wasps, mostly of the species whose biology was previously unknown, and much of it previously published in Japanese journals ... this is a worthwhile book that will materially contribute to a more pluralistic study of the evolution of advanced insect societies.'
