The evolution of vinegar flies is based on the variation of male sex pheromones

Max Planck researchers decipher the chemical language underlying mating in 99 species of the genus Drosophila. By analyzing the genomes of 99 species of vinegar flies and evaluating their chemical odor profiles and sexual behaviors, researchers at the Max Planck Institute for Chemical Ecology show that sex pheromones and the corresponding olfactory channels in the insect brain evolve rapidly and independently.
