Squid eye different from human eye

I need better wording to be able to understand this..

As animals evolved, many of the shared traits between species are the same or at least similar because the two species at some point shared a common ancestor that had that trait.

Humans and squids are very distantly related, meaning our last common ancestor with squids had lived a really really long time ago. This common ancestor did not have eyes like the ones seen today (if anything it may have had little sensors that somewhat recognized light). This means that the eyes that humans have and the eyes that squids have both evolved completely separately, even though they are so similar. This type of phenomenon is known as convergent evolution.

i find that impossible to believe. my cousin is a squid and we have the exact same eyes.

.............seriously, no shit our eyes evolved separately

Yeah?! Well why do monkeys have eyes?!

Now it is such a bizarrely improbable coincidence that anything so mindbogglingly useful could have evolved purely by chance TWICE that some thinkers have chosen to see it as a final and clinching proof of the non-existence of God.
The argument goes something like this: "I refuse to prove that I exist," says God, "for proof denies faith, and without faith I am nothing."
"But," says Man, "the eye is a dead giveaway isn't it? It could not have evolved by chance. It proves you exist, and therefore, by your own arguments, you don't. QED."
"Oh dear," says God, "I hadn't thought of that," and promptly vanishes in a puff of logic.

Did they actually evolve separately?
I wish to see evidence.
Because this is badass.

No problem, bud. Because I'd love to dig up science docs for a website with pictures of cats browsed primarily by twelve-year-olds.

People honestly believe that it all happened by chance, I just don't get it

The way you worded this explains exactly why you disagree
"I just don't get it"

Actually over 50 completely different eyes have evolved at different times. Eyes are complex, they just happen to be easy to build as well.

The idea that all life on Earth came form a common ancestor is scientific fact. I don't see how it's debatable.

Regardless, nature is frickin' sweet just as long as you're not int he thick of it.

As a bio major, I give you my two cents FJ:   
   
One common ancestor that squids and humans shared was a strange little creature called Anomalachairus, a kind of pre-chordate who's decendants would go on to develop a notochord (primitive spinal chord).  It was part of a class of creatures called the eurypterids.     
   
It was aquatic and looked a lot like a scorpion but swam and was about a meter long.  Fossils of it can be found in the Burgess Shale from 500 million year ago (Cambrian period).     
   
It had simple eyes that were raised on stalks and could sense light and simple shapes, enough so that it could use them to locate food and predators, ect...   
   
Eyes were a pretty fucking revolutionary thing and two very different creatures evolving in the same way (i.e. squids & humans) is called convergent evolution and happens all the time in biology:  Sharks and dolphins evolving some of the same traits for an open ocean pelagic existence.     
   
TL;DR:  Useful things often evolve at different times in nature and this is incredible.  Squids & humans shared ancestors way back in the day.

Actually some would say more evolved than mammals, the eyes of a cuttlefish with their w shape allow for a really dynamic view of their world.

This is further proof that evolution is bullshit and there is a creator behind everything.

I always find it funny when people say "Eyes are too complex to have evolved!"

It's really not that far-fetched/complicated. Photoreceptive cells are beneficial to just about any organism, so it's no wonder that organisms who developed them survived to reproduce; and with time and numerous changes (for example, the number of the cells, the shape that they form) eyes as we understand them would of course develop.

I don't see what's so hard for people to understand about this and evolution in general.

I'm dubious about this. Not hating on you, but can you give me a citation? There are examples of eyes on life forms dating back to some of the earliest life forms so I think it might be a homologous structure. I could be wrong since I have no idea, but it makes sense to me that we are both evolved from a previous ancestor. Most multicellular life forms have eyes after all.
