"What we see of the real world is not the unvarnished real world but a model of the real world, regulated and adjusted by sense data - a model that is constructed so that it is useful for dealing with the real world. The nature of that model depends on the kind of animal we are. A flying animal needs a different kind of world model from a walking, a climbing or a swimming animal. Predators need a different kind of model from prey, even though their worlds necessarily overlap. A monkey's brain must have software capable of simulating a three-dimensional maze of branches and trunks. A water boatman's brain doesn't need 3D software, since it lives on the surface of the pond in an Edwin Abbott Flatland. [...] The point is that the nature of the model is governed by how it is to be used rather than by the sensory modality involved. [...] The general form of the mind model - as opposed to the variables that are constantly being inputted by sensory nerves - is an adaptation to the animal's way of life, no less than its wings, legs and tail are." Richard Dawkins - The God Delusion
