A comprehensive and authoritative review of the current scientific knowledge of how evolution has shaped the brains of Australian marsupials.

Marsupials differ from most other mammals in their method of reproduction, in that they have chosen, in an evolutionary sense, to develop lactation rather than placentation for the nurture of their young. The neonate is therefore born with a mixture of advanced and embryonic characters, and yet is readily accessible within the pouch, providing a unique system for the study of the ontogeny of various physiological and endocrinological parameters. Marsupials are therefore ideal animals for research into mammalian reproductive physiology. The results of this exciting new research are summarized in this book by two of the foremost workers in the field. Individual chapters analyse the genetic and hormonal control of sexual differentiation, male and female reproductive structures and their functions, the role of the corpus luteum in the oestrous cycle and pregnancy, the hormonal control of embryonic diapause and the role of the marsupial placenta in the development of the embryo. This book is more than just a straightforward review of marsupial reproduction for its detailed analyses and broad comparative coverage will attract mammalogists and reproductive physiologists with a wide range of research interests.

The aim of this book is to examine a variety of problems in the understanding of the evolutionary history of the marsupials. In his exposition, the author covers developmental and reproductive biology, the cranio-skeletal system (including dentition, skull and postcranial morphology) and the ecologically related aspects of skeletal morphology. In reviewing the evidence from bones, he presents much new information on both living and fossil groups of marsupials. All groups of marsupials are treated in detail, and in the final chapter their history in space and time and their palaeobiogeography are considered.
