Da te stvarno zanima procitao bi clanak u kojem je detaljno objasnjena evolucija oka.
Imamo razne stadijume evolucije vida , od bukvalno jedne celije koja moze da razlikuje samo svetlo i mrak do izuzetno naprednih ociju koje imamo mi i mnoge druge zivotinje.

okejj ali kako je nastala osnovna/ prvobitna ćelija/senzor za detekciju svetlosti ...na osnovu čega ?

The basic light-processing unit of eyes is the photoreceptor cell, a specialized cell containing two types of molecules bound to each other and located in a membrane: the opsin, a light-sensitive protein; and a chromophore, the pigment that absorbs light. Groups of such cells are termed "eyespots", and have evolved independently somewhere between 40 and 65 times. These eyespots permit animals to gain only a basic sense of the direction and intensity of light, but not enough to discriminate an object from its surroundings.[22] "
"
A photoreceptor cell is a specialized type of neuroepithelial cell found in the retina that is capable of visual phototransduction. The great biological importance of photoreceptors is that they convert light (visible electromagnetic radiation) into signals that can stimulate biological processes. To be more specific, photoreceptor proteins in the cell absorb photons, triggering a change in the cell's membrane potential. "

Ako te dalje zanima kako su nastali najjednostavniji oblici zivota za to niko nema odgovor trenutno.

ovo je objašnjenje funkcije svetlosnog senzora ali ne i nastanka, ali kao što ti reče još nije utvrđeno
kao i čula ukusa, mirisa, sluha, dodira...

teorija evolucije se dovede u sumnju svaki put kada udari u zid pitanja o prapočetku nastanka osnove
