Leon Vlieger in The Inquisitive Biologist:
Justifiably, the book opens with sensory biology. Before we understand what is in the mind of any organism, Chittka argues, we first need to understand the gateways, the sense organs, through which information from the outside world is filtered. These are shaped by both evolutionary history and daily life (i.e. what information matters on a day-to-day basis and what can be safely ignored). Chapter 2 deals with the historical research that showed that bees do have colour vision and furthermore can perceive ultraviolet (UV) light. Many flowers sport UV patterns invisible to us. Remarkably, UV photoreceptors are found in numerous insects and other crustaceans whose shared ancestry goes back to the Cambrian, predating the evolution of flowers in the Cretaceous by hundreds of millions of years. In other words, it seems flowers adapted to insect colour vision rather than the other way around.
