Abstract The colorful phenotypes of birds have long provided rich source material for evolutionary biologists. Avian plumage, beaks, skin, and eggs—which exhibit a stunning range cryptic conspicuous forms—inspired early work on adaptive coloration. More recently, avian color has fueled discoveries the physiological, developmental, and—increasingly—genetic mechanisms responsible phenotypic variation. relative ease with which traits can be quantified made an attractive system uncovering links between phenotype genotype. Accordingly, field coloration genetics is burgeoning. In this review, we highlight recent advances emerging questions associated genetic underpinnings bird color. We start by describing breakthroughs related to 2 pigment classes: carotenoids that produce red, yellow, orange in most psittacofulvins similar colors parrots. then discuss structural colors, are produced interaction light nanoscale materials greatly extend plumage palette. Structural remain understudied—but paradigm changing. next explore how arise from interactions among pigmentary may controlled genes co-expressed or co-regulated. also identify opportunities investigate mediating within-feather micropatterning bare parts eggs. conclude spotlighting research areas—mechanistic vision production, speciation—that been invigorated insights, trend likely continue as new genomic approaches applied non-model species.

Abstract Some butterfly species such as the orange oakleaf ( Kallima inachus ) have strikingly different colors on dorsal (front) sides of their wings compared to those ventral (back) wings, which helps camouflage butterflies from predators and attract potential mates. However, few human‐made materials, devices, technologies can mimic differential coloring for a long time. Here, new type Janus‐structured two‐sided electrochromic device is developed that, upon application voltages, exhibits coloration state one side that distinctly other side. This achieved by inserting an optically thin (4–8 nm) metallic layer with complex refractive index, composed tungsten, titanium, copper or silver, into typical structures.

Drosophila melanogaster males perform a series of courtship behaviors that, when successful, result in copulation with female. For over century, mutations the yellow gene, named for its effects on pigmentation, have been known to reduce male mating success. Prior work has suggested that influences behavior through wing extension, song, and/or vigor. Here, we rule out these explanations, as well nervous system more generally, and find instead success are mediated by pigmentation male-specific leg structures called sex combs. Loss expression modified bristles reduces their melanization, which changes structure causes difficulty grasping females prior copulation. These data illustrate why mechanical properties anatomy, not just neural circuitry, must be considered fully understand development evolution behavior.

In diverse organisms, nanostructures that coherently scatter light create structural color, but how such structures are built remains mysterious. We investigate the evolution and genetic regulation of butterfly scale laminae, which simple photonic nanostructures. a lineage buckeye butterflies artificially selected for blue wing we found thickened laminae caused color shift from brown to blue. Deletion optix patterning gene also altered via lamina thickening, revealing shared pigments thickness. Finally, show thickness variation contributes diversity distinguishes sexes species throughout genus Junonia. Thus, quantitatively tuning one dimension architecture facilitates both microevolution macroevolution broad spectrum hues. Because is an intrinsic component typical scales, our findings suggest available mechanism across Lepidoptera.

Synopsis The concept of trade-offs permeates our thinking about adaptive evolution because they are exhibited at every level biological organization, from molecular and cellular processes to organismal ecological functions. Trade-offs inevitably arise different traits do not occur in isolation, but instead imbedded within complex, integrated systems that make up whole organisms. genetic mechanistic underpinning can be found the pleiotropic nodes pathways shared between traits. Yet, often only understood as statistical correlations, limiting ability evaluate interplay how selection constraint interact during evolution. Here, we first review classic paradigms which physiologists evolutionary biologists have studied highlight ways network pathway approaches unify these paradigms. We discuss allow researchers why act overcome trait correlations constraints. argue understanding conserved functions provides a conceptual framework for biologists, physiologists, meaningfully work together toward goal briefly melanocortin system hormonal control osmoregulation two case studies where an reveals seemingly unrelated While recognize applying such poses challenges limitations particularly context natural populations, advocate view focusing on responsible unified accessible broad range integrative biologists.

In Lepidoptera (butterflies and moths), a genomic region around the gene cortex is hotspot locus, repeatedly used to generate intraspecific melanic wing color polymorphisms across 100-million-years of evolution. However, identity effector regulating within this locus remains unknown. Here, we show that none four candidate protein-coding genes including cortex, serve as major effectors. Instead, micro-RNA (miRNA), mir-193, serves three deeply diverged lineages butterflies, its function conserved in Drosophila. Lepidoptera, mir-193 derived from gigantic long non-coding RNA, ivory, it functions by directly repressing multiple pigmentation genes. We miRNA can drive repeated instances adaptive evolution animals.
