FISHING and hunting by humans may drive evolution in a way unlike anything else on Earth, and the rapid changes triggered in wild species risks severe damage to ecosytems. Chris Darimont, an evolutionary ecologist at the University of California at Santa Cruz, and his team, reviewed 34 studies that measured how fast traits such as body size and growth rate had changed in 29 species that people harvest for food. The average rate of change was three times as fast as comparable changes seen in unhunted populations, they found (Proceedings of the National Academy of Sciences, DOI:
