What is the future of evolution? In the final essay in Science's series in honor of the Year of Darwin, Carl Zimmer explores the subject of human-driven evolution. Since Darwin's day, humans have gained an unprecedented influence over our own evolution. At the same time, our actions, be it causing climate change, modifying the genomes of other organisms, or introducing invasive species, are creating new sources of natural selection on the flora and fauna around us. If there's one thing that's certain, it's that humans, like other living things, will continue to evolve; medical advances and other changes to human life have not stopped natural selection, nor will they in the future.
