title: The neurogenetics and evolution of food-related behaviour.
abstract: All organisms must acquire nutrients from the ambient environment to survive. In animals, the need to eat has driven the evolution of a rich array of complex food-related behaviours that ensure appropriate nutrient intake in diverse niches. Here, we review some of the neural and genetic components that contribute to the regulation of food-related behaviour in invertebrates, with emphasis on mechanisms that are conserved throughout various taxa and activities. We focus on synthesizing neurobiological and genetic approaches into a neurogenetic framework that explains food-related behaviour as the product of interactions between neural substrates, genes and internal and external environments.
