The February issue of National Geographic features an extraordinary up-close look at the eyes of various animal species.
As part of the magazine feature, British science journalist Ed Yong discusses the anatomy and evolution of eyes, including how an animal’s environment contributes to the function and appearance of its eyes, and how it sees the world.
Yong discusses the science behind animal eyes with zoologist Dan-Eric Nilsson of Lund University in Sweden. “If you ask people what animal eyes are used for, they’ll say: same thing as human eyes,” says Nilsson in National Geographic. “But that’s not true. It’s not true at all.”
