Larval swimming in the sea anemone <i>Nematostella vectensis</i> is sensitive to a broad light spectrum and exhibits a wavelength‐dependent behavioral switch Open
In nearly all animals, light‐sensing mediated by opsin visual pigments is important for survival and reproduction. Eyeless light‐sensing systems, though vital for many animals, have received relatively less attention than forms with charis…

Multiple parallel expansions of bilaterian-like phototransduction gene families in the eyeless Anthozoa Open
Opsin-mediated phototransduction cascades in photoreceptor cells are primarily responsible for light-mediated behaviors in animals. Although some visual cascades are well-studied, phototransduction mediated by non-visual opsins and in non-…

Sex-linked gene traffic underlies the acquisition of sexually dimorphic UV color vision in <i>Heliconius</i> butterflies Open
The acquisition of novel sexually dimorphic traits poses an evolutionary puzzle: How do new traits arise and become sex-limited? Recently acquired color vision, sexually dimorphic in animals like primates and butterflies, presents a compel…

<i>Nematostella vectensis</i>exemplifies the exceptional expansion and diversity of opsins in the eyeless Hexacorallia Open
Background Opsins are the primary proteins responsible for light detection in animals. Cnidarians (jellyfish, sea anemones, corals) have diverse visual systems that have evolved in parallel with bilaterians (squid, flies, fish) for hundred…

Insect opsins and evo-devo: what have we learned in 25 years? Open
The visual pigments known as opsins are the primary molecular basis for colour vision in animals. Insects are among the most diverse of animal groups and their visual systems reflect a variety of life histories. The study of insect opsins …

Sex-linked gene traffic underlies the acquisition of sexually dimorphic UV color vision in <i>Heliconius</i> butterflies Open
Butterflies have photoreceptor cells that are sensitive to the ultraviolet part of the spectrum due to ultraviolet-sensitive rhodopsin ( UVRh ), a gene that has been duplicated in the Heliconius genus. In individuals expressing UVRh1 and U…

Multiple Mechanisms of Photoreceptor Spectral Tuning in<i>Heliconius</i>Butterflies Open
The evolution of color vision is often studied through the lens of receptor gain relative to an ancestor with fewer spectral classes of photoreceptor. For instance, in Heliconius butterflies, a genus-specific UVRh opsin duplication led to …

Cephalopod Retinal Development Shows Vertebrate-like Mechanisms of Neurogenesis Open
Neurogenesis, the regulation of cellular proliferation and differentiation in the developing nervous system, is the process that underlies the diversity of size and cell type found in animal nervous systems. Our understanding of how this p…

Co-option of the Limb Patterning Program in Cephalopod Lens Development Open
Across the Metazoa, similar genetic programs are found in the development of analogous, independently evolved, morphological features. The functional significance of this reuse and the underlying mechanisms of co-option remain unclear. Her…

Multiple mechanisms of photoreceptor spectral tuning following loss of UV color vision in<i>Heliconius</i>butterflies Open
Color vision modifications occur in animals via a process known as spectral tuning. In Heliconius butterflies, a genus-specific UVRh opsin duplication led to the evolution of UV color discrimination in Heliconius erato females, a rare trai…

Krüppel-like factor/specificity protein evolution in the Spiralia and the implications for cephalopod visual system novelties Open
The cephalopod visual system is an exquisite example of convergence in biological complexity. However, we have little understanding of the genetic and molecular mechanisms underpinning its elaboration. The generation of new genetic materia…
