Document Summary
The ability to evolve eyes through natural selection over time is very important. Chlamydomonas eyespot it shares many characteristics with the human eye such as retinal and the 7 transmembrane protein. They types of cells that got recruited into becoming important to the eye are very different. Maybe pac6 used to do something else but through tinkering it became important to the. Development of the modern eye. Pax6 is seen as a global regulator of eye development. Two major types of photoreceptor cells. *it is important not to confuse photoreceptor (rhodopsin) with photoreceptor cells: ciliary photoreceptor cells, microvillar photoreceptor cells. If you knockout one of the domains, you knockout the function of pax6 and the development of the eye. Tinkering with heat shock proteins. Eye structure: we care about the photoreceptor cells (rod/cone) which is where the light gets absorbed. If you look at your cones, cones come in three types. You can have dichromats, trichromats, quatra, hexa, penta etc.
