Fish adapted colour vision in blink of evolutionary eye

Discovery highlighted a new UBC study which found that stickleback fish adapted their vision to new environments in less than 10,000 years–a blink of an eye in evolutionary terms.

The process took less than 10,000 years but would have taken other animals at least 100 times as long, researchers said.

“This is a very short time scale for large changes in colour vision to evolve,” said lead researcher Diana Rennison. “We’d typically expect species to adapt their vision over time spans in the millions of years.”
