Convergent spectral shifts to blue-green vision in mammals extends the known sensitivity of vertebrate M/LWS pigments.
(PNAS, 2020-04-14)
Daylight vision in most mammals is mediated predominantly by a middle/long wavelength-sensitive (M/LWS) pigment. Although spectral sensitivity and associated shifts in M/LWS are mainly determined by five critical sites, ...
Nectar-feeding bats and birds show parallel molecular adaptations in sugar metabolism enzymes.
(Elsevier, 2021-08-27)
In most vertebrates, the demand for glucose as the primary substrate for cellular respiration is met by the breakdown of complex carbohydrates, or energy is obtained by protein and lipid catabolism. In contrast, a few bat ...
Parallel independent losses of g-type lysozyme genes in hairless aquatic mammals.
(Oxford University Press, 2021-08-27)
Lysozyme enzymes provide classic examples of molecular adaptation and parallel evolution, however, nearly all insights to date come from c-type lysozymes. G-type lysozymes occur in diverse vertebrates, with multiple ...
Convergent phenotypic evolution of rhodopsin for dim-light sensing across deep-diving vertebrates.
(Oxford University Press, 2021-08-31)
Rhodopsin comprises an opsin attached to a retinal chromophore, and is the only visual pigment conferring dim-light vision in vertebrates. On activation by photons, the retinal group becomes detached from the opsin, which ...
