Adaptive genomic evolution of opsins reveals that early mammals flourished in nocturnal environments

BMC Genomics, 2018
Background Based on evolutionary patterns of the vertebrate eye, Walls (1942) hypothesized that early placental mammals evolved primarily in nocturnal habitats. However, not only Eutheria, but all mammals show photic characteristics (i.e.
