Fruit fly sex drive hints at how animals choose behaviors [Phys]

Male fruit flies have a mating drive, and its rise and fall is controlled by dopamine levels in one area of the brain, a team of Harvard Medical School neurobiologists has found.
The discovery provides insight into the nature of motivation across species, the researchers said.
"None of us is really interested in flies or their sexual behavior," said Dragana Rogulja, assistant professor of neurobiology at Harvard Medical School and co-senior author of the study. "We’re trying to understand how animals make and carry out decisions to perform or not perform a behavior."

Yet one of our most important biological traits, consciousness, is rarely studied in the context of evolution. Theories of consciousness come from religion, from philosophy, from cognitive science, but not so much from evolutionary biology. Maybe that’s why so few theories have been able to tackle basic questions such as: What is the adaptive value of consciousness? When did it evolve and what animals have it?
