Question

explain the evolution of eyes

Answer 1

The evolution of the eye has attracted significant study, with the eye distinctively exemplifying an analogous organ present in a wide variety of taxa. Complex, image-forming eyes have evolved independently some 50 to 100 times.

Complex eyes appear to have first evolved within a few million years, in the rapid burst of evolution known as the Cambrian explosion. No evidence of eyes before the Cambrian has survived, but a wide range of diversity is evident in the Middle Cambrian Burgess shale, and in the slightly older Emu Bay Shale.Eyes show a wide range of adaptations to meet the requirements of the organisms which bear them. Eyes vary in their visual acuity, the range of wavelengths they can detect, their sensitivity in low light, their ability to detect motion or to resolve objects, and whether they can discriminate colours.

Answer 2

$\large\bold{ Evolution \:of\:eyes}$

➡ the eye is a very important organ for animals. The eye is a complicated organ which cannot be separated by a single DNA change. The complete body organs of animals such as eyes have been created in "stages" over many generations. First of the all rudimentary I like that of a flat warm was formed. The eyes of flatworm was very simple that are actually just spots which can detect light. Even these rudimentary eyes provide a survival advantage to platform. Starting from this basic design more and more complex as where then evolve in various organisms. Most of the animals have eyes. For example, the insects, Octopus and invertebrates, all have eyes. The structure of eyes in each of these organisms is, however, different with suggest there separate evolutionary Origins. $<b>$The evolution of eye is an example of evolution by stages.
