no matter how many wavelengths of light it can see, they all fit into the spectrum of visible colors we call red, orange, yellow, green, blue, indigo, and violet. There are no mind-blowing new colors to look at. It's all just the seven visible shades, because that's everything you can comprehend.
Not just several colours, several PRIMARY colours. You mix our 3 with eachother and you get 3 additional secondary combinations (purple, green and orange). You look at the mantis shrimp's 16 total primary receptors, and imagine how 256 secondary colours would look and each tertiary shade of those colours -purple more on the blue side, or purple more to the red side. Mantis shrimp is so ******* pointlessly awesome
We actually have pretty good vision when compared to the rest of the animal world. Cats have pretty blurry vision. Same thing with dogs. That is why we are so dependent on vision and not smell.
We have pretty good detail and color vision, but in terms of seeing moving things, not that good. It's why dogs aren't interested in looking at televisions unless they're expensive one's with really high framerates; they can see the flickering frames on normal TV's so it doesn't look interesting.
Except that we don't override any instincts.
Instinct to eat, we eat.
Instinct to have sex = Tinder and hookup culture.
Instinct to procreate = majority of people have at least one child during their lifetime.
Instinct to kill = Hunting
If anything, we're even more slaves to our biology the more we engage in primal bestial behaviour that hookup culture encourages.
The only thing that put us on top was our ability to think forward and create tools and weapons.
Just because some of us don't override our instincts doesn't mean we can't. Obivously we eat because otherwise we would die, and instict to kill? wtf? I'm the only person I know who's under forty that hunts, is instict to kill even a thing?
I've seen this claim thrown around. I'm curious if you have a source for it. I've seen plenty of examples other mammals, let alone other clades of animals, wander around with injuries that would make people pass out.
If this claim hinges on modern medicine letting us recover that doesn't really count, then other animals could recover with the same treatment too, and before medicine people died all the time from even stupid little injuries, let alone major stuff.
Communication
Resilience (able to go on with broken bones, missing limbs, whatever)
Able to run, climb, and swim
Great hunting skills (Again, communication, plus the endurance, plus intelligence allowing to read tracks and strategise)
Also, humans are pretty much the only species able to actually really throw stuff (Monkeys can, too, but they don't even come close)
Our biggest thing is our versatility. There are animals that swim better than us, run faster, climb better. But we can do all three decently.
Most things humans can do, some animal can do better. But we got it all in one convenient package, plus the intelligence to figure out when to use what skill.
Our greatest asset is the sheer processing power that our brain possesses. How else do you think we would've created a civilization, nevermind harnessed nuclear fission, landed on the moon, and created the internet.
that is just blatantly false.
The human eye is well-capable of seeing UV light , our brain just finds it redundant to process and filters it out instead.
People can see UV light, your retina does respond to it, however the lens of your eye blocks it. People who had their lens(es) removed or replaced with artificial ones can in fact see UV light.
Some people can also see into the higher bands of infrared. I can.
ok that makes some sense. the eye "sees" the light, but the lense filters it out because i assume that **** isnt good for the squishy bits in your eye?
a squishy organ dedicated to absorbing light? extra defenses wouldn't surprise me. although, as i write this, i recall that skin in general is fairly UV resistant. Perhaps UV resistance is a human thing overall, not just dedicated to eyes... idk, just thinking aloud.
I feel inclined to disagree with your original comment. A rare few people will actually see UV light, because you require Aphakia to be able to have the capacity to truly see it. UV is just outside of the visible spectrum, so we cannot naturally observe it, so I would say your original point is wrong. If, according to your logic, redundant wavelengths were filtered out, then that would mean we see ALL wavelengths of light. However, you are correct in the sense that it goes through the eye and is ignored, but in technical terms, that's not strictly a true statement. It's purely subjective opinion as to whether your statement is true or not, but because the eye lens absorbs the UV to prevent it entering, I'll take my side and say you were wrong. I can see that you've provided the actual facts elsewhere in the comments though, but I'll confirm for you that the lens DOES absorb UV because of it's danger to the eyesight.
In case you're interested in any further information, the damage that causes the ability to see UV is simply the absence of the lens. UV light is seen as it's closest wavelengths, which is a purple-blue blend or white. When seen, it can cause direct damage to the cells, but the interesting thing is that some animals see 4 colours instead of 3, and observe UV as an entirely different colour we cannot comprehend. Pretty ******* cool. I dunno if you needed any more information, so just shout if you need me.
alright, cool thanks. it just seems odd to me, y'know? like if its just inane useless information, then why would other animals ever use it? and on top of that, why would specifically UV be useless? what makes it less useful then other colours in the spectrum
well, the best possible vision id say is the ability to percieve the whole spectrum of light. but no creature we know of can, the mantis shrip i think is the best vision, but no creatue can see all wavelengths of light.
if you could, youd see heat, youd see colours which humans cant even percieve, youd see radiation, gamma rays and such,
I believe we can tell based on their brain structure, eye structure, and the number of retinal cones(red,green,blue) and rods(black,white) the animal has. Possibly along with some behavioral observations.
What colors you see is determined by these little tube thingies filled with pigment inside your eyeballs. You can tell what colors an animal can see by just looking at the pigments inside.
The fish one is false, as is the bird one.
Each species sees the world differently.
Robins can see the curvature or the magnetic field of the earth.
Goldfish can see colour but not UV light, they have the same cones in their eyes and see the world the same as we do.
Its a similar mechanism to what happens to people in extreme situations- the senses go into emergency mode, and the brain starts processing things extremely quickly, giving you a chance to react (so everything looks like tis inw lsow-motion), but it usually also looks black and white because the brain is using all the possible processing power to analyse every little moment and can't bither with unnecessary things like information from the rods, i.e. colour.
Like bruh what if we had different pigments we woud have totally different concepts of color. Like if you pointed at something "green" it wouldnt look green to the other person.
