In PLoS Medicine, vol 2, issue 7, DOI: 10.1371/journal.pmed.0020215 The following sentence contains an incorrect number: “Only by massaging the numbers could one figure out that physicians would need to put 700 women on statins to eliminate one cancer case (in medical parlance, this is called number needed to treat)....

Introduction It has long been hypothesized that the increased complexity and genome size of vertebrates has resulted from two rounds (2R) of whole genome duplication (WGD) occurring in early vertebrate evolution, thus providing the requisite raw materials [1]. This seemed to be supported by the long-standing speculatio...

As one of the most important sources of novel gene functions, gene duplications play a major role in evolutionary change. Though a gene copy will generally become inactive after duplication, it can be saved—either by acquiring a new function or dividing aspects of the original gene's function—on its way to becoming ubi...
