Blind Civilizations

Lol, sure, continue making up scenarios that are impossible.

This is going basically how I predicted, the way of the underwater civs discussion.

Blind underwater plant space whale Civ when

Plant civs actually went ok if you ignore that one really long mixotroph argument.

What do you mean

The space whales and underwater civs arguments went horribly, but the only horrible argument on plant civs was that one mixotroph one, if you don’t know what I’m talking about just look at the plant civ thread.

Edit: oh lol I’m sentient now.

Literally possible and basically like humans eating citrus for the vitamin C but more complex,
Also, 50gens is a plant civ confirmed.

are you joking?
do you realise the incomprehensibility of what you said?
that idea is so mind numbingly wrong and impossible that i cant even put into words how it wouldnt work

what i meant was this:
it would be possible for something to eat eyes and extract the photosensitive pigments from the cones and rods of the eyes by basically having a more complex and actually parasitic version of the relationship humans have with citrus(we eat part of the tree to get something we need but cannot make, they eat parts of animals to get things they cannot make, this is obviously an oversimplification but i don’t know how to make it readable and not an oversimplification so i cant really fix that)

also 50gens is tribal and a plant so 50gens is plant civ confirmed

Willow, Your idea has already been tried in the real world. Here are some parasites which cause blindness from the World Health Organization and Center for Disease Control.

For example, Onchocerciasis, Also know as river blindness, is a parasitic worm spread by black flies and infects eyes;
~220 million people are at risk of the parasite, of those ~1 million have gone blind, diseases like these were certainly extremely common or outright ubiquitous throughout most of history and nearly all species.
Despite this eyes are still everywhere, it is evident that parasites alone are not a good justification to not have eyes.

Unless they aren’t just eating the eyes and exist everywhere and are the dominant species because they did what the humans used to

I have one question
Do y’all realise what category this thread is in?
Its in the future game category
For Thrive
Things like parasites ending the existence of eyes will NOT be a thing

You don’t know that. I have two points to consider:

  1. It is generally impossible to say with certainty what the future will hold.
  2. The people who are obsessed with promoting far-flung ideas of barely feasible organisms and societies coming about could take over the game development, leading to all civs consisting of self-contradictory underwater-space whale-plant super-predator-pacifists, whose bodies are super-enduring, ultrafast, supersized, ultra-thin and probably banana-coloured.

Saying that eye eating organisms will make organisms with eyes extinct is like saying that carnivores will make herbivores extinct.

Needing to jump through a bunch of hoops to make an explanation work is not convincing at all.

Yea i doubt that such a thing will happen

i actually didn’t until’ you said something about it

Did a kleptoplast on me form a microcivilisation and became spacefaring?

That isn’t a creature that eats your eyes and leaves.

Why would a species evolve eyes, but not be able to synthesise all the molecules needed for sight? Humans stopped making vitamin C because they were already consuming a lot of fruits.

I thought of another motivation for targeting eyes. You can have an armor all over your body, but not in the eye, unless glass eyes evolve. If you are an animal like a rhino and an animal like bat approaches you, it can use the most vulnerable spot in your body to start drinking your blood. If those bats increase in population and there is now one bat for every other creature, then sight can’t be done in that patch anymore. The creatures then may devolve eyes to have a complete armor.

But other senses can do the same job as sight for an awakening stage species. But also an awakening species would have hands and could protect itself against bats approaching from above. Maybe this is a bad idea.

But there are also rogue planets without a star that are in complete darkness. They can stay in a habitable temperature with tidal heating*. The primary producers can do chemo or thermosynthesis, and intelligence can still evolve.

A lack of enough energy may be an issue. Hydrothermal vents are few and far between, also not abovewater. There wouldn’t be forests and wildlife without light, maybe only microbial or sessile life. Someone else may try to come up with an idea.

I don’t really see much of an issue with a blind species creating civilisation and advanced tech. Pretty much everything I can think of relating to our important scientific discoveries are either easy to hear, feel, or smell; or they are impossible to sense even with vision

The only real counterexamples are optics and the stars, though the latter is a rather important counterexample. Light generally would probably be easy to discover, as even if they couldn’t detect it themselves they would notice it clearly from the behaviour of sighted animals. From this basic knowledge they could probably get to a photodetector of some sort. The final hurdle would be to think of using light to make images, and to use this to image the sky

Imaging requires optics, which are another obstacle. However, the basics might be derived from the anatomy of animal eyes, and suitable materials could be discovered with photodetectors. With this knowledge making a camera is not that implausible

Finally, using this camera on the sky could easily come as an attempt to predict the weather

What about an animal that eats the eyes to reach the brain as that is more likely to happen without the player needing to make every species have armor on everything but the eyes
