(Phys.org) —A pair of researchers from the University of Zurich in Switzerland has found that pre-adaptive traits, (which they call exaptations) appear to be far more common than adaptive traits. In their paper published ...
(Phys.org) —Scientists at NASA's Ames Research Center, Moffett Field, Calif., now have the capability to systematically investigate the molecular evolution of cosmic carbon. For the first time, these scientists are able ...
