Reproductive skew in Japanese sardine inferred from DNA sequences [PDF]
ICES Journal of Marine Science, 2016 AbstractAn excess of low-frequency mutations is a ubiquitous characteristic of many marine species, and may be explained by three hypotheses. First, the demographic expansion hypothesis postulates that many species experienced a post-glacial expansion following a Pleistocene population bottleneck. The second invokes some form of natural selection, such
