    One gene, many mutations

    In a new paper, Harvard researchers show that changes in coat color in mice are the result not of a single mutation, but of many mutations, all in a single gene. The results start to answer one of the fundamental questions about evolution: Does it proceed by huge leaps — single mutations that result in…

    Designing gene

    Taking advantage of the simple color pattern of deer mice, Harvard researchers showed that small changes in the activity of a single pigmentation gene in embryos generate big differences in adult color pattern.
