then just as there is a little diversity between big groups of types of creatures there would be after all that time fantastic diversity in EYES.
There is but you expect to see square eyes that use sound waves to see that just does not work evolution cant make something that does not work or ever will.
All eyes are round because it works
All eyes have some thing that allows light to enter them because that is how they work
All eyes range in diameter from x cm to y cm because they cant get any smaller, and any larger is a waste of resource

there is only so much diversity an eye can have that utelises its best efficiency for the task.
We dont have the eyes of a Hawk because the need was never selected for that strongly we have the optimum eye for our environment, the positive efects of a hawks eyes are smaller in comparrison for the resources it would use that we spend on other parts, Better eyesight would need a larger portion of the brain devoted to it and so limiting other parts of the brain like the ones responsible for logic and reasoning thus making us actually far less effective at passing on our gens because we would be out competed.
Perhaps what you are really asking is why dont we see different sense organs.
Well we do
You have the eye
The sonar
Normal ear function
taste
tuch
infraread
and you have various ways in the way they are utilized like the snake smelling with its tung.
The eyes of mammals alone should be almost unrecognizable compared to each other.
So how do you really think they should look? Give me an example of the difference one would see.
P.s. i really should not post stuff when im stoned so if all this makes no sense just ignore it
