How do sticklebacks survive?
Stickleback fish are able to adapt their vision to new environments in less than 10,000 years, a blink of the eye in evolutionary terms, according to new research. The fish adapted by altering the expression of their opsin genes, which encode the light-sensitive receptors on retinal rod and cone cells.
