However, recent studies (for a review see ref. 6) have revealed that well developed color vision appeared long before the evolution of fruits and flowers.
Based on the analysis of (a) Current economic, ecological and socio-cultural dynamics, (b) Currently planned future technologies, as well as (c) Currently developed visions of the future and future plans of individuals and institutions, plausible hypotheses about future developments are possible with all the requisite circumspection.
Due to four distinct cone receptor visual pigments in vertebrates, color vision is well developed in fishes, reptiles, and birds., These pigments, which provide sensitivity to light in the UV to infrared range, are thought to have been present in ancestral vertebrates.
Because vision is important in the life of a trout, the eyes are well developed; the retina possesses both rods (for vision in dim light) and cones (for perceiving more acute images and for colour vision).
A koala's vision is not well developed, and its relatively small eyes are unusual among marsupials in that the pupils have vertical slits.
Color vision in fishes is taxonomically widespread and well developed (Loew and Lythgoe 1978; Lythgoe et al. 1994).
Fast predatory sharks tend to have more acute vision, and in some deep-diving species the eyes are well developed to maximize detection of ambient light.
Because of the well developed visual and locomotor system, predatory teleosts are excellent models for studying the relationship between vision and body movement [24].
Vision, of little importance in the caecilian's environment, is not acute; however, the nasal organs are well developed, and chemosensory perception is greatly enhanced by the existence of a tentacle (see chemoreception).
Wine tourism is well developed.
Commercial poultry farming is well developed.
