Human perspective of human perception

How do we actually see the world? Do we see it as it actually is, or do we see it exclusively through the human lense?

Take a spoon, when you look at the inside of a spoon, you see the image upside down. Our human eyes are also concave, just like a spoon. Our visual cortex at the back of our brain automatically flips it around to view it in the orientation we perceive to be "correct" because the little ingeniously crafted bone/fluid system in our inner ear sends a little electrical signal to another part of our brain that tells us we're all lined up.

Take the ability for animals like squid and octopus to alter their physical appearance so well, to the extent they fool even human intelligence;


At the end of this clip, one of the scientists wonders what the implications of this discovery are. These things are colorblind, they're performing this level of camouflage by some other mechanism than is currently known by humans.

My initial perception was that we pretty much know how things work, there are small tweaks here and there and sometimes you'll come across a big discovery that changes the way we think about something, but overall, we have a pretty good grasp on things.. Stuff like this makes me question that thought. It makes me wonder how other animals and ultimately, how an alien species might evolve.
