In 1970, Professor Geoff Parker alerted biologists to the fact that sexual selection proceeded after the act of mating, at the level of the gamete.The exciting and novel research outcomes of a micro-revolution in sexual selection are reported here across the chapters of 'Sperm Evolution'.
The editors have gathered a veritable glitterati of reproductive biologists to author this book, with outstanding records in sperm evolution, from broad to intimate perspectives. Sperm Evolution does an excellent job of breaking down boundaries between biological disciplines, and without taxonomic bias, by integrating current knowledge across a wide range of expertises within sperm biology, from protein biochemistry and biophysics to evolutionary theory and social aspects of human fertility. The overall package provides an in-depth understanding of this important cell from a questions-driven research perspective, within the simple Darwinian framework that underpins all biology.
There is plenty in this book for both researchers and lay-readers. For the latter, amazing facts such as the 6cm long sperm of Drosphila bifurca will surely impress even the most cynical of cocktail-party guests. For the researchers, this book is packed with up-to-date facts and concepts by true leaders across the field.
Readers of this book can be confident that they are absorbing information about an exponential rise in reproductive biology with broad perspectives, which is set to continue; there remains great potential for important scientific discoveries to be developed and many are identified throughout. What explains the exceptional variety in sperm morphology? Sperm of some species show profound changes in behaviour throughout their life-history, such as hyperactivation or immotility: what mechanisms control this and why? We know that female-derived signals can attract sperm: how do sperm orientate across such gradients? Evidence is increasing that female differential sperm selection is a real phenomenon: how does it happen and how much haploid information do sperm express? On entering the egg, are there undiscovered mechanisms within the ovum before haplotype fusion? Fertilization is a remarkably important, yet still poorly understood, mechanism across the majority of taxa, and this book addresses these questions and develops answers from what is currently known.
