Abstract
Ovaj seminar bavi se osnovama građe očiju beskralješnjaka te njihovim evolucijskim razvojem. Različiti tipovi oka u životinjskom svijetu razvili su se više puta tijekom evolucije, a njihova sličnost među različitim koljenima dobar je primjer konvergentne evolucije. U jednostaničnih organizama nalazimo fotoreceptore u obliku očnih pjega, ekvivalentnih pigmentnim pjegama primitivnih višestaničnih organizama. Pigmentne pjege se tijekom evolucije produbljuju u čašice i razvijaju dodatne strukture sa svrhom usavršavanja vida, povećavajući preciznost, oštrinu i lom svjetlosti. Istovremeno se događa i razvoj dijela živčanog sustava zaduženog za obrađivanje podataka koje šalje oko. U člankonožaca se razvijaju i usavršavaju složene oči sastavljene od mnogo omatidija, dok se u glavonožaca, kralješnjaka te u nekih žarnjaka razvijaju jednostavne oči kompleksne građe. Možemo zaključiti da složenost građe očiju odražava okolinu i način života pojedinog organizma.
Abstract (english)
This paper deals with the basic builds of invertebrate eyes and their evolutionary development. Different types of animal eyes developed multiple times over evolution's course, their similarity among various phyla serving as a good example of convergent evolution. In single-cell organisms, photoreceptors most commonly take the form of eye spots, corresponding to pigment spots in primitive multicellular organisms. Over the course of evolution, pigment spots deepen into pigment cups, acquiring additional elements with the purpose of enhancing vision by increasing precision, acuity and refraction of light. The nervous system grows simultaneously in order to process information from the eye. Arthropods evolve multi-faceted compound eyes, while cephalopods, vertebrates and some cnidarians evolve simple eyes of complex build. We can conclude that the complexity of eyes reflects the environment and mode of existence of various organisms.
