Speed Limit To The Pace Of Evolution, Biologists Say
November 3, 2009 | Source: ScienceDaily
University of Pennsylvania researchers have developed a theoretical model that provides quantitative predictions for the speed of evolution on various “fitness landscapes,” the dynamic and varied conditions under which bacteria, viruses and even humans adapt.
A major conclusion of the work is that for some organisms, possibly including humans, continued evolution will not translate into ever-increasing fitness.
