The insect dopaminergic system serves an important function in the regulation of ontogenesis and early development, contributing to the evolutionary processes that limit the ecological niche of Drosophila sechellia.

The optimal macronutrient composition, macronutrient space, varies strongly between closely related species and is determined by genetic changes in regulatory genes that globally reprogram gene expression profiles of metabolic pathways.

A 'hotspot' position in an olfactory receptor protein family underlies changes in odor tuning in different receptors at different times during evolution.

The evolutionary transition of the agricultural pest Drosophila suzukii to egg laying on ripe fruits was paralleled with several gustatory innovations.
