Children of Prometheus: The Accelerating Pace of Human Evolution

Ever since Darwin published The Descent of Man , we have wondered about the future of our species. Will we separate into H.G. Wells's Morlocks and Eloi, or will we stay pretty much the same? Biologist Christopher Wills tackles this big question in Children of Prometheus , claiming that yes, indeed we are changing in significant ways, despite assertions by many scientists to the contrary. Evolution can be seen as an improvisational dance performed by DNA and the environment--each equal partners until just a geological moment ago, when one species--ours--began to have a profound impact on the environment, changing everything. Wills describes how we have indirectly slowed, sped up, or stopped (through extinction) the evolution of many species, and suggests that our environmental manipulations are accelerating the rate at which we ourselves are changing with each generation. His lucid explanations of evolutionary mechanisms and heritability studies greatly help non-technical readers grasp his points, but even professional scientists will benefit from his review of the psychogenetic literature. In the end, Children of Prometheus can't tell us what our distant descendents will look like; we can only look in a mirror and wonder how they will differ. --Rob Lightner
