Scientifically speaking explain how the fuck people think ayys of all things would look like a modified human

Convergent Evolution

Earth has a lot of intelligent animals and tool using animals. Yet only hominids rose up. As they have the all the right set of features. So it is a logical extrapolation. That aliens capable of space travel will look roughly humanoid.

IIRC it has something to do with the way we expect biology to develop based on how gravity effects bones, tissue, etc.

The assumption goes that for an animal to reach the same technological level as us or further, they would likely need to have some physiological similarities including large brains and limbs to create and operate tools.
I think sci-fi artists could be more creative than humans with slightly different facial features without being unrealistic but you can't really say "anything goes" when it comes to technologically advanced, alien life.

[Anonymous No.12122555]

I think its perfectly reasonable to assume that intelligent, space-traveling aliens would look similar to humans but only if they arose on a planet with similar environmental conditions (atmosphere, gravity) otherwise it becomes much more unrealistic

Greys are an extrapolation of human evolution. As we have evolved we've traded a lot of our physical ability for bigger brains, and we compensate with technology. They are logically what advanced creatures might look like, but still similar enough for us to relate to them in fiction.

There's also of course the idea that we are directly related and ayys are either ancient visitors that created us or time travelling future-humans.

Given how intelligent some birds are, could dinosaurs have replaced hominids as the first tool using, intelligent species if the meteor never hit?

[Anonymous No.12122613]

>>12122589
Which dinosaurs would it be though? It would likely be a bipedal, large brained species, basically as close to human physiology as dinosaurs got.

Its a big universe and much older than this planet. Given enough time and opportunity eventually something would evolve somewhere that looks like us. They would probably be especially interested in the planet with people that look just like them.

It's very unlikely that a sentient extraterrestrial life form would look exactly like a human, but there are some things we can expect with moderate confidence. Assuming they are carbon-based, they would have a comparatively large brain and a body to support it, at least two eyes, a set of manipulative limbs and locomotive limbs, no more than 8 in total due to their large energy consumption.

X number of limbs are needed to be functional
Y number where Y<=X are needed for interacting with the environment.
Not including the head, mouth, or tongue humans have four limbs they use to interact with their environment.
Say cellular life is the easiest to come into being, from that you'd need to be multi-cellular, likely.
The planet likely gets decent light for heat from a star.
So it forms.
it creates features that are effective at specialized tasks, these can be considered essentuial structures or organs.
Sexual reproduction or a kind, assuming DNA is the easiest way to create and manage life, is most effective, especially for variation.
so a limbed being like we see commonly i most animals, and all intelligent animals, is very likely.
having many limbs cost a lot fo energy and would be indicative of their environment.
Four limbed fish succeeded most on our earth.
It'll need lots of competition to force it into the niche of intelligence.
it needs to be social probably to develop even more intelligence and commutative work.
it probably needs to be a certain size too.
but aside from that how it looks exactly would be based off its environment.
it's unlikely it'll look like modified humans.

If anything they would be a central brain and organ sac surrounded by manipulator limbs. Like an octopus but with more fine motor control.

They would be silicon based and also based as fuck

Those who think about probably imagine convergent evolution. Those who go with modern traditions are likely influenced by generations of human actors portraying aliens in make-up. Those who actually imagine they see humanoid aliens I believe are the results of human brain wiring preferentially generating certain kinds of hallucinations. (Although my own experiences with hallucinations tend to be more towards spiders.)

because source for that type of ayylmaooo is earth. It's earth based phenomenon (other dimension). That's why they got so mad after first nukes got detonated. It disturbed their world.

Aquatic life cannot into technology. They can't use fire. So no external energy to help process food, keep warm, and make tools.

Hard to make tools and other shit when not humanoid. If they were to also evolve it would make sense if they were Atleast some what humanoid.

Can’t make tools and fire really underwater. Without fire can’t really do much. Also on land being an octopus isn’t the best.

I'd like to think they would advance as a civilization in a completely, otherworldly different way to how apes/humans advanced as a civilization but I realize this starts going into more science fiction then anything.

[Anonymous No.12126707]

the occurrance of life like ours would possibly share more similarities than differences. A seemingly emergent property of our diverse life no matter the ecosystem or cellular dna structure.

The environments for planets we have discovered for our dfinition of habitability of carbon based biochemistry to take place for carbons abundance and rare elemental property for forming 4 stable bonds (with silicon only stable with 3) is in the millions or possibly billions; more accurate looks into probablility that for a species to technologically evolve with stable non extinction level carbon oxygen climate than whose to say they wouldn't be so different after our initial shock. Unless they are advanced enouhg to travel here they can look however they want.

I don't see why more limbs would consume more energy (they need to divide the same amount of work), the difference more likely is the impossibility of running with more than four and climbing with more than two.

You lot are assuming conditions far too similar to that those on Earth, citing that fire is needed for progression and comparing number of limbs etc. What about a gas planet? Or Venus, where the chemistry is so utterly different on the surface that fire cannot even exist, let alone what reactions could be taking place that we haven't understood yet. There are way too many factors at play to even think about convergent evolution
