A review of The Future of Aging: Pathways to Human Life Extension. The Longevity Project: Veronique Greenwood on how decades of data reveal paths to long life (and more). Technology advances, humans supersize: Nobel-winning economist Robert Fogel and his colleagues track the startlingly fast changes in human height and longevity since 1700. Do we want to be supersize humans? There's room for debate. On the plains of New Mexico, a band of elite marathoners tests a controversial theory of evolution: that humans can outrun the fastest animals on earth. Annalee Newitz on the first sign that humans are on the verge of evolving into another species. Harvey Fineberg shows us three paths forward for the ever-evolving human species: to stop evolving completely, to evolve naturally — or to control the next steps of human evolution, using genetic modification, to make ourselves smarter, faster, better. Julian Savulescu argues that moral enhancement using biological techniques may hold the key for the future of humanity, faced with problems such as global warming, terrorism, and poverty. Kyle Munkittrick on why cognitive enhancers are not “cheating”. Rise of the Machines: As computers get smarter, experts examine the potential implications. Even robots can be heroes: Researchers have challenged the idea that relatedness is necessary for altruism's evolution. Fight, Fight, Fight: Charles Q. Choi on the history of human aggression. Nice guys finish first: Developments in the study of evolution suggest that the survival of the fittest depends as much on cooperation as it does on a competition between self-interests. From Anthropology in Practice, does cooperation really make it happen? Where does good come from?: Harvard's Edward O. Wilson tries to upend biology, again. Researchers challenge E. O. Wilson over evolutionary theory.
