Evolution of sensory systems in the dark biosphere. This project utilises a unique Australian model system based on multiple, independently-evolved subterranean water beetles to explore the adaptive and regressive changes in the genome that occur when surface species colonise subterranean habitats. We aim to characterise and investigate the evolution of chemosensory and circadian rhythm genes, which play critical roles in the fitness of animals, including the ability to find food and mates in a ....Evolution of sensory systems in the dark biosphere. This project utilises a unique Australian model system based on multiple, independently-evolved subterranean water beetles to explore the adaptive and regressive changes in the genome that occur when surface species colonise subterranean habitats. We aim to characterise and investigate the evolution of chemosensory and circadian rhythm genes, which play critical roles in the fitness of animals, including the ability to find food and mates in a dark, thermally stable environment. Knowledge of chemosensory and circadian genetic systems and how they dynamically evolve is fundamental to a variety of fields, including the process of speciation and biological adaptation (for example, to permanent darkness, pollutants and insecticides).Read moreRead less
