Theoretical considerations of eye design allow us to find routes along which the optical structures of eyes may have evolved. If selection constantly favours an increase in the amount of detectable spatial information, a light-sensitive patch will gradually turn into a focused lens eye through continuous small improvements of design. An upper limit for the number of generations required for the complete transformation can be calculated with a minimum of assumptions. Even with a consistently…

The developed simulated eye model demonstrates that the requirement to detect the direction of an approaching predator does produce a gradual evolutionary transition from a flat light sensitive surface to the pinhole camera eye which models how eyes evolved in biological creatures.

The selective advantages of using light as a source of information are reflected in the diverse types of extant eyes, and specific genes and their products are used repeatedly, making causal relationships more difficult to discern.
Vision in nature through GRIN media: smart optical design
The role of the GRIN structure in the lens will be closely examined using optical models with ray-tracing and the overview of various solutions in nature for clear vision is presented and discussed with the emphasis on the optical design.
Eye evolution simulation with a genetic algorithm based on the hypothesis of Nilsson and Pelger
This work addresses for the first time the simulation of the evolution of an elemental eye by means of a simple genetic algorithm and shows how eye evolution could take place gradually applying the principle of natural selection.
Superior to one of Glass: Natural Gradient index Lenses via Patchy Particle Self-Assembly
To achieve acute and sensitive vision in a camera-like eye in the ocean, a graded refractive index spherical lens is required to maximize the photon flux on the retina, while leaving an eye structure

The spiders are the only other group to make use of a single cornea as the optical system in their main eyes, and some of these – the salticids – have evolved a remarkable system based on image scanning.

It is suggested that a corresponding evolutionary sequence is suggested, starting at non-directional monitoring of ambient luminance and leading to comparisons of luminances within a scene, first by a scanning mode and later by parallel spatial channels in imaging eyes.

This collection of observations strongly suggests that eyes have had multiple origins with remarkable convergence due to physics and molecular conservation of the opsin protein.

The optical system of fishes
This chapter will discuss two major features of fish visual systems: optics, which is the collection of light and formation of an image by the lens, and accommodation,Which is the focusing of images on the retina.
The evolution of eyes.
This review of the diversity of eye types and their optical evolution suggests that once suitable biochemical solutions are found, they are retained, even though their "packaging" varies greatly.

Genetic Variation and Phenotypic Evolution During Allopatric Speciation

It is concluded that Mayr's theory of allopatric speciation overemphasized both the genetic cohesion of widespread species and the founder effect on heterozygosity and quantitative genetic variation, and data on the strength of natural selection and the spontaneous mutability of quantitative characters provide a feasible microevolutionary mechanism for substantial and geologically rapid phenotypic evolution in small isolated populations.
