The article focuses on the findings of the study conducted by Catherine Peichel and colleagues on genes underlying behavioural evolution in a population of sticklebacks in Japan. They found in their DNA testing that male fish that showed aggressive bumping had inherited a piece of chromosome 9. After five-year plus of work, the team found genetic evidence that a stickleback population in the Japan Sea has a new sex chromosome that explains the aggressive mating behavior of its males.
