(PhysOrg.com) -- New research in the U.S. has discovered that fruit fly larvae have a series of photoreceptors covering the body that can detect light even when their primitive "eyes" are covered or removed.
The more complex a plant or animal, the more difficulty it should have adapting to changes in the environment. That's been a maxim of evolutionary theory since biologist Ronald Fisher put forth the idea in 1930.
