Approximately two decades after the first pioneering analyses, the study of shape asymmetry
with the methods of geometric morphometrics has matured and is a burgeoning field. New …

Geometric morphometrics—a set of methods for the statistical analysis of shape once
saluted as a revolutionary advancement in the analysis of morphology—is now mature and …

The visual ecology of flies is outstanding among insects due to a combination of specific
attributes. Flies' compound eyes possess an open rhabdom and thus separate rhabdomeres …

Divergent populations across different environments are exposed to critical sensory
information related to locating a host or mate, as well as avoiding predators and pathogens …

G-protein coupled receptors (GPCRs) play important roles in cell biology and insects'
physiological processes, toxicological response and the development of insecticide …

Drosophila R7 UV photoreceptors (PRs) are divided into yellow (y) and pale (p) subtypes.
yR7 PRs express the Dpr11 cell surface protein and are presynaptic to Dm8 amacrine …

About two-thirds of the vital genes in the Drosophila genome are involved in eye
development, making the fly eye an excellent genetic system to study cellular function and …

Independent evolution has resulted in a vast diversity of eyes. Despite the lack of a common
Bauplan or ancestral structure, similar developmental strategies are used. For instance …

Radiodonts are nektonic stem-group euarthropods that played various trophic roles in
Paleozoic marine ecosystems, but information on their vision is limited. Optical details exist …

In this article, Matute et al. report an experiment in which they generated eight interspecific
admixed populations using two species pairs of Drosophila. They found that in both species …
