What does a bee see?

Human vision is an extraordinarily sophisiticated thing, backed up by some serious brain power. So how then, can a bee with a tiny brain, find its way over several kilometres through messy terrain to a food source and back again? The answer is both remarkably clever and surprisingly simple. While bee vision has been studied for many decades, there is still much to be learned. One of the hardest perhaps, is to let go of the assumptions that bee vision is just a simpler version of what human do. Emeritus Professor Adrian Horridge has a distinguished career in many areas of science, including years in the company of bees. Interview by Rod.
