Damian Moran, who led the study, says vision is costly because “of energy-hungry photoreceptive cells and neurons.”

As underground caves are often poor in food and oxygen, natural selection “would favor individuals with reduced visual capacity,” he says.

“Any animal that lives in permanent darkness and doesn't need vision to find food or avoid predators won't really need their eyes or visual centers in the brain,” adds Moran, currently a researcher at Seafood Technologies Group, Nelson, New Zealand.

Now if science could only figure out who rigs every Oscar night.
