“When Gehring injected Mouse PAX6 into fruit fly embryos, the resultant fruit flies had eyes all over where they had been randomly injected, but these eyes were fruit fly eyes, not mouse eyes.”

In general, mammals don’t have the best color vision. In part, that’s because our ancestors developed trying to see in the dark, not out in the bright sunlight. “There was a time where to be a mammal was to be a small, nocturnal, rodent-like mammal,” said Duke’s Sonke Johnsen, author of the book, The Optics of Life. Both humans and whales retain the marks of that evolutionary path. “Our color vision is kind of a kluge,” Johnsen continued. “If you look at the color vision of birds and reptiles and fish. It’s very well put together, nicely optimized. You look at our trichromatic vision, it’s really kind of pieced together.”
