Three-Spined Sticklebacks
Three-Spined Sticklebacks possess the ability to evolve remarkably quickly. Their species is a master at adaptive radiation, producing over ten new variations in less than 20,000 years - a mere blink of an eye in the ordinary evolution timeline. These fish frequently interbreed, producing stable and healthy offspring, ready to foster new species.![Three-Spined Sticklebacks](https://learning.royalbcmuseum.bc.ca/wp-content/uploads/2017/12/three-spined-stickleback-480x360.jpg)
