Evolutionary biologist Jay Storz and colleagues at UNL and Aarhus University, Denmark, found that whether a given mutation is good or bad often is determined by other mutations associated with it. Studying genetic variation in the hemoglobin protein in deer mice populations from different elevations, they found certain individual mutations that increased hemoglobin\u2019s binding affinity for oxygen in some mutational combinations, but decreased it in others. Because these mutations have context-dependent effects, the order in which mutations occur can determine which pathways evolution is more likely to follow, said Storz, Susan J.
