This multi-authored book edited by Philip G. Cox and Lionel Hautier highlights the evolutionary history of rodents, as revealed by complementary fields such as phyloge-netics, paleontology, functional morphology, biomechanics, and developmental biology. It is the fifth published volume of a new Cambridge University Press series entitled "Cambridge Studies in Morphology and Molecules: New Paradigms in Evolutionary Biology". As such it allows for positively reconciling molecules, fossils and morphology as irreplaceable clues of a sole story. I guess that for virtually any paleomammalogist, this book would irredeemably recall the volume "Evolutionary Relationships Among Rodents: a Multidisciplinary Analysis" edited thirty years ago by W. P. Luckett & J.-L. Hartenberger. The latter authors were opportunely invited to sign a foreword, punchy as usual and pointing wisely the rise of novel approaches
