Improbable Destinies

Good popular science book. Losos gives a good overview of the state of experimental evolutionary science, focusing on the concepts of convergence and contingency. Well written, Losos's book is accessible to interested non-specialists as well as professional evolutionary biologists and paleontologists.
Vincent Poirier's review is the one to read. He says what I was thinking, but more eloquently.
4.5 stars.
