Evolution is not only the slow process that ruled the rise and fall of the dinosaurs over hundreds of millions of years. It also happens quickly -- so quickly and frequently that it changes how all of us live our lives: drugs fail because diseases evolve; insects overcome the most powerful pesticides; HIV and tuberculosis develop resistance to the newest drugs in a few months. This is evolution with teeth.While the ecological scars of human technology have been well publicized, the broad evolutionary consequences of antibiotic and antiviral use, insecticide applications, and herbicide bioengineering are largely unexplored. Does the human impact on evolution falter at the borders of our own species? Or do we, in fact, generate our own evolutionary pressure?Enthusiastically written for a wide audience, The Evolution Explosion examines these practical and critical aspects of modern evolution with simplicity, force, and humor.

As Palumbi explains, scientists now recognize that evolution is not some primordial force that disappeared with the dinosaurs. They can watch it transform animals and plants over the course of years, not eons.
...
Life has been evolving for four billion years, and the processes that Palumbi describes have been acting on it since the beginning. By comparing the genes and fossils on different branches of the tree of life, scientists can reconstruct the history that produced the animals, plants and microbes that are still evolving today. ''The Evolution Explosion'' is a good introduction to the Darwinian change that is taking place all around us, but it's far from the whole story.
