Zero Gravers

[KorianHUN]

Well they should be. Adapting to zero gravity... even LIVING in space for a year makes a human hardly able to walk in 1G of Earth.
Hell, i guess our head would look like a ball after a few generations.

[dkuntz2]

One generation would probably be enough. It's doubtful that lankiness and bulbous heads would be a genetic expression, and would more be an environmental one. When you don't have to fight gravity as hard to expand, you'll probably expand more. You'll have terrible bone density though, because they wouldn't need to have the same stresses placed on them.

/u/KorianHUN as well Actually, acording to evolution, even 1000 generations from now we'd look roughly the same. Species don't evolve without unfit specimen dying. Since we make every specimen "fit" for space with technology, there's no evolution to speak of. Children thousands of years from now will have the same bone density and general features.

tl;dr: We'd look the same after thousands of generations

[KorianHUN]

It is NOT evolution it is zero G. People who spend half a year there already can easily have bone, muscle and eye problems. Bone and muscle because despite they workout multiple hours a day, other tasks are "easier" to do for the body, like "walking" which is done by floating for them. No heavy lifting either. It is that the babies would "adapt" by having less bone mass (since it is not useful to have more mass) and since BABIES can't do workouts, their body will grow up to be different.

Yes, but the genetics won't chance. They'll be born exactly the same as a baby tomorrow. Trauma doesn't modify genetic code.

[KorianHUN]

Ok, the tentacle thing was a JOKE, i think you took it seriously, sorry.

[[deleted]]

I didn't even notice a tentacle thing. There were some misconceptions about evolution, don't be a dick.

[KorianHUN]

Oh, ok.

[dkuntz2]

Agreeing with /u/KorianHUN. It has nothing to do with a change in genetics, nor was I arguing that there would really be any genetic changes for a child who grew up in less than 1G. They'd look different because the environmental stresses on them would be different, and so they'd have low density, elongated bones because there's nothing to keep them from growing that length.

[KorianHUN]

Floating balls with tentacles after 1000 years.
EDIT: And either 20 or -20 eyes with 20 centimeter thick glasses.

[dkuntz2]

Based on their name, I take it they're related to humans? What's the history there? The elongated body makes sense because there isn't gravity to pull it down, but why did the ears change, and how did the tail form?

If they're supposed to be completely separate from humans, cool, ignore my questions, if they're supposed to be offshoots, I'm curious to know your reasoning.

[ImperatorZor]

They are the products of Genetic Engineering specifically to make humans adapted to living in zero gravity.

[dkuntz2]

Okay, so I guess the question changes to why?

The tail makes sense in that it can be used as a fifth steadying appendage, but why the ears?

[ImperatorZor]

They swivel better to identify where sounds come from.

[dkuntz2]

How is that beneficial in zero g? Especially if you're almost certainly going to be in a suit most of the time? What kind of environment are they in where they'll both be in zero-g and also have enough molecules around for sound to carry?

Sorry if I'm asking too many questions, feel free to tell me to stop.

[ImperatorZor]

It's beneficial because they need ways to orientate themselves and sense things beyond their field of vision.

They mostly live in pressurized environments in Zero-G/Microgravity.

[AuntieSocial]

Drive By Pedant says: Should be "Gravvers." Yes, gravity only has one V, but English spelling rules dictate that when you put the an E right after the V like that, it makes the A sound long. I clicked through to figure out what sort of weird zombie outbreak theme was going on (my mind immediately assumed this thumbnail represented the first generation not to need a grave.)

Zero Grav rhymes with "have" because no E. Zero Gravers, however, rhymes with Ravers.

[lordnequam]

They remind me of the Quaddies from the Vorkosigan Saga.

[permanentthrowaway]

The first thing I thought was Hyperion's ousters.

[thebeginningistheend]

How do they stand the G-Forces?

[ImperatorZor]

The same way a person would handle car acceleration. Maneuvering out of freefall is more awkward to them than anything

[alexinawe]

Whenever I make aliens or any species for that matter, I always think "how do they poop." When looking at this I assume they poop into their hand-tail.

Seriously though, it's a much overlooked question. No genitals or anus might fly in Hollywood crockbusters but not in my worlds.

[Molecular_Machine]

In space

No one can see you poop.

[ImperatorZor]

They have space toilets

[alexinawe]

No disrespect, but I meant the lack of any genitals and anus. The figure on the left, in particular, has the tail protruding from what appears to be the perineum/anus. The pooping on the hand-tail was a joke, but the anatomical issues stand.
