The evolutionary origins of the three major families of chemoreceptors in arthropods—the
odorant receptor (OR), gustatory receptor (GR), and ionotropic receptor (IR) families …

Social insect colonies have evolved many collectively performed adaptations that reduce the
impact of infectious disease and that are expected to maximize their fitness. This colony …

Olfactory systems must detect and discriminate amongst an enormous variety of odorants.
To contend with this challenge, diverse species have converged on a common strategy in …

The olfactory system must recognize and discriminate amongst an enormous variety of
chemicals in the environment. To contend with such diversity, insects have evolved a family …

Around 150 million years ago, eusocial termites evolved from within the cockroaches, 50
million years before eusocial Hymenoptera, such as bees and ants, appeared. Here, we …

Epigenetic inheritance is fundamentally important to cellular differentiation and
developmental plasticity. In this review, we provide an introduction to the field of molecular …

Although DNA methylation is an important gene regulatory mechanism in mammals, its
function in arthropods remains poorly understood. Studies in eusocial insects have argued …

Walking is a rhythmic locomotor behavior of legged animals, and its underlying mechanisms
have been the subject of neurobiological research for more than 100 years. In this article, we …

Among the many wonders of nature, the sense of smell of the fly Drosophila melanogaster
might seem, at first glance, of esoteric interest. Nevertheless, for over a century, the 'nose'of …

Ants communicate via large arrays of pheromones and possess expanded, highly complex
olfactory systems, with antennal lobes in the brain comprising up to∼ 500 glomeruli. This …
