If there are Aliens what do you think they look like?

Answer 1

i think that Nature likes simple things, so I doubt that they have, say, multiples eyes on multiple tentacles and the like

we know, from stellar spectra, that pretty much the same elements are present, in the same proportions, pretty much anywhere in the universe

so there's a good chance that these same elements for the same molecules everywhere

so there's a good chance that the forms of life we see on Earth, or have seen on Earth, are good indicators

you could imagine intelligent reptiles. there's pretty good evidence that some dinosaurs were fairly intelligent, that some were hot blooded, so if we had not had that mass extinction, maybe we'd have had civilised reptiles, with mammals remaining marginal

other thoughts? two eyes are great to judge depth, so minimum of two eyes. must be in a rigid structure because two eyes on tentacles don't keep a constant distance so cannot be used to judge depth. what about more than two eyes? only if presents a huge survival advantage, because eyes are very complex units so Nature would have to have to implement many. evolution on Earth suggests that a rotating head is a cheaper way of producing something similar.

brain has to be close to eyes, and ears, etc., and all that stuff should be as high as possible for better detection (of predator, or prey) - so you'd have a head, with a brain in it, at the top of the body, with eyes and ears and nose attached

of course the eyes could vary a bit (look at a frog's) - but you'd most certainly have an organ to detect some part of the EM spectrum (maybe more than just our "visible light", for example infra-red, seen by snakes or sharks, or ultraviolet, seen by bees). the ears could also vary (look at a bat's) - but you'd certainly have something to detect vibrations of the milieu. the nose could vary a lot - but you'd certainly have something to detect what molecules are in the "air".

you could have other senses - for example sharks are able to detect electric fields.

bones? the nice thing about a skeleton, is that it saves a lot of effort. so very probably a skeleton.

arms? we've got just two. is three arms or more an advantage? not sure that it outweighs the complexity of adding arms. but who knows. maybe two arms, supplemented by a couple tentacles, could be useful. same reasoning for legs.

all in all, that's all i envision on small, rocky planets

now, of course, if you go for totally different setups (gas giants), then why not imagine giant, floating beasts? or why not imagine some de-incarnated intelligence living in the center of neutron stars?

hope this helps a bit?

Answer 2

Should alien life have evolved somewhere else, you would expect them to be a product of the environmental conditions of the would on which they evolved. If earth-like conditions existed elsewhere then terrestrial (land) species only have a limited amount of options for mobility etc. You would expect legs and arms and fingers as the beasts would need these in order to survive (at least bigger, flightless ones). However the different designs of animals on earth are almost limitless. The chance of an alien looking exactly the same as a human or even a humanoid is almost impossible. You can't escape your phylogeny and alien lifeforms would have different looking ancestors than we did. (That's if you take a scientific approach - personally I believe that there is no other life in the universe)

Answer 3

What aliens look like depends on there envirnment.

Example: We have legs because we have to walk, fish because they have to swim.

What ever the conditions are to survive on that planet would evolve the aliens to "fit its criteria".

Maybe if the aliens planet was closer to a star than earth is to its star, but the star was weak enough to sustain life but was so close that it blinded the eyes, then those perticular aliens would have black eyes. A natural tint to them.

What ever the condition.

I know its a gay example but you get the point damnit.

So before we can speculate what a alien race looks like we have to know the properties of the planet they live on.

Answer 4

Aliens proliferate throughout the universe.
You could never predict their appearence.
Imagine trying to predict what life looked like on earth.
One thing is certain they would need a DNA language to specify what they are and how they looked,

Answer 5

Some look like Fez on That's 70s show. I would think you couldn't tell, unless they told you. Or do you mean space aliens? I think they all look like ET. If they don't, they should. He's so cute.

Answer 6

they are brown and usually driving a full load of aliens in a dark green chevy van running away from the border patrol at a high rate of speed up the I5

Answer 7

Woody Allen

Answer 8

Do you think they'll be carbon-based beings like us? Or perhaps silicon-based. Either way, there's no intelligent design in our development, so i doubt aliens would be any different. Most likely, they'll be bugs.

Answer 9

some of the photos on the yahoo answers.
or take a look at bush, blair, the pope, cheney, qe2, prince charles. maybe the bullsh*t they tell you hides the truth.
look at these web site, david icke, artic beacon, bilderberg

Answer 10

Hard to say...look at how many different species there are just here on Earth!
They could evolve into beings we can't even imagine.
