Darwin Comes to Town: How the Urban Jungle Drives Evolution

by Menno Schilthuizen
Menno Schilthuizen is a Dutch biologist based at Leiden University, in a country whose population is more urban than rural. In other words, he inhabits the future. His new book, Darwin Comes to Town alerts us to new evidence about the pace of evolution. By watching the evolutionary play as it runs in urban theaters, not just wildish ones, Schilthuizen and some colleagues—you might think of them as postmodern biologists, making the best of highly urbanized twenty-first-century landscapes—have noticed that evolution’s tempo can be surprisingly brisk. Fast evolution in cities is the theme here, unfolding toward a suggestion that perhaps new species are being born in our time, while many older ones are being driven to extinction.
