Although males and females largely share the same genome and nervous system, they
differ profoundly in reproductive investments and require distinct behavioral, morphological …

The Drosophila sex comb (SC) has been hailed as a powerful tool for integrative studies in
development, evolution, and behavior, but its ontogeny is poorly understood, even in the …

Although nervous system sexual dimorphisms are known in many species, relatively little is
understood about the molecular mechanisms generating these dimorphisms. Recent …

How is cell fate diversity reliably achieved during development? Insect sensory organs have
been a favorable model system for investigating this question for over 100 years. They are …

Propagation in higher animals requires the efficient and accurate display of innate mating
behaviors. In Drosophila melanogaster, male courtship consists of a stereotypic sequence of …

Many traits responsible for male reproduction evolve quickly, including gene expression
phenotypes in germline and somatic male reproductive tissues. Rapid male evolution in …

Similar selective pressures can lead to independent origin of similar morphological
structures in multiple evolutionary lineages. Developmental mechanisms underlying …

Acquisition of distinct neuronal identities during development is critical for the assembly of
diverse functional neural circuits in the brain. In both vertebrates and invertebrates, intrinsic …

The origin of new morphological structures requires the establishment of new genetic
regulatory circuits to control their development, from initial specification to terminal …

The development of the Drosophila olfactory system is a striking example of how genetic
programs specify a large number of different neuron types and assemble them into …
