Most adaption processes have a polygenic genetic basis, but even with the recent explosive
growth of genomic data we are still lacking a unified framework describing the dynamics of …

The field of population genomics has grown rapidly in response to the recent advent of
affordable, large-scale sequencing technologies. As opposed to the situation during the …

Melanins are widespread pigments in vertebrates, with important roles in visual signaling,
UV protection, and homeostasis. Fossil evidence of melanin and melanin-bearing …

Experimental evolution is well-suited to test the predictability of evolution without the
confounding effects of inaccurate forecasts about future environments. Most of the literature …

Birds exhibit remarkable variation in plumage patterns, both within individual feathers and
among plumage patches. Differences in the size, shape, and location of pigments and …

Repeated evolution can provide insight into the mechanisms that facilitate adaptation to
novel or changing environments. Here we study adaptation to altitude in two tropical …

With novel human–wildlife interaction, predation regimes, and environmental conditions, in
addition to often fragmented and smaller populations, urban areas present wildlife with …

Adaptation is central to population persistence in the face of environmental change, yet we
seldom precisely understand the origin and spread of adaptive variation in natural …

Coloration has been associated with multiple biologically relevant traits that drive adaptation
and diversification in many taxa. However, despite the great diversity of colour patterns …

Albinism is a conspicuous and distinctive phenotype arising from the absence of melanin in
the integument that has been documented in all major vertebrate groups. With few …
