Oh, to have been a fly on the wall for the gathering that resulted in this volume!
It is the battle cry for modern evolutionary biologists who see phenotypes as the targets of selection and thus feel shut in by the reductionist, modern synthesis approach to evolution (read: population genetics). There's something here for everyone, and whether or not you agree that it's really necessary to call for an "extended synthesis," the contents of this book show that evolutionary biology is alive and well.
Perhaps the most influential book I've read about evolutionary theory since Developmental Plasticity & Evolution, I will without a doubt be returning to the wisdom in this volume over and over again.
Livro denso, com uma boa revisão sobre a síntese moderna e perspectivas sobre o que tem mudado e para onde estamos rumando. Ótimos capítulos, escritos por gente competente e com uma visão bem ampla.
