“In a world of relentless environmental change, occurring at a rate unprecedented in human history, the issue of the speed of evolutionary adaptation has taken on great significance. Which species and populations will be able to adapt and continue to deliver natural services to humanity? What rates of change will still make adaptation possible and maintain ecosystem functioning? We know that evolution is not the gradual process once imagined, and that natural selection can act very quickly, but when, where, and how will evolution be fast enough to help civilization to survive? Relentless Evolution, written by a distinguished evolutionary biologist, brilliantly provides the scientific background against which these and related questions can be addressed. Everyone who cares about the environment will want it on their shelf.”
