Darwin Comes to Town

A growing band of 'urban ecologists' is beginning to realize that natural selection is not so easily stopped. They are finding that more and more plants and animals are adopting new ways of living in the seemingly hostile environments of asphalt and steel that we humans have created. Carrion crows in the Japanese city of Sendai, for example, have learned to use passing traffic to crack nuts for them; otters and bobcats, no longer persecuted by humans, are waiting at the New York City gates; superb fairy-wrens in Australia have evolved different mating structures for nesting in strips of vegetation along roads; while distinct populations of London underground mosquitoes have been fashioned by the varied tube line environments.

Menno Schilthuizen shows us that evolution can happen far more rapidly than Darwin had dared dream
