If there are alien life forms, what do you think the chances are that they looks like us humans?

Answer 1

Fairly low chance, unless they evolved from monkeys like us. They probably have totally differant animals on their planet. (may have evolved from frogs??

The other possibility is where it is said that humans were a genetic experiment or we were helped along by an alien race that spliced our dna with their own to make us more intelligent than the ape men that we were.

Answer 2

First off, "alien life forms" does not necessarily mean they have to be intelligent. If you meant "alien life forms with an intelligence equal to or greater than humans," then considering the narrow band of biological chance that led to the evolution of Man, I would suspect that, barring slight variation due to variables, non-Earth intelligent beings would be some what similar. Even on Earth, there are variations of race due to climate conditions, so one could rule out an exceptional climate creating beings that are physiologically different in this regard. Whatever the case, these creatures would have to have some way to manipulate their environment, and this would dictate a physique not unlike humans.

Answer 3

If you look at the evolutionary process that has occured on this planet culminating in erect, bipedal, intelligent lifeforms and imagine the probability that each exact step will occur on some other planet, factor in the conditions within our own solar system, the range of energies from our sun, the effects of Jupiter etc etc - then the chance is vanishingly small.

I would say that if we met an extra-terrestial life form that even vaguely resembled homo sapiens then this would constitute absolute proof of a divine maker in action.

However if the universe is truly infinite then even the smallest probability will occur somewhere ... just a thought.

What is really interesting is to consider Earth is 4,500 million years old. Intelligent life (defined by creating art e.g. cave paintings) has only been around for say 50,000 years. This is something like .0001% of the lifetime of our planet. Any other planet developing life would certainly be Millions of years behind us OR millions of years ahead... go figure ....

Answer 4

Studying the different life forms that have evolved on the Earth under different conditions and completely separately suggests that there is a very limited range of possibilities for how an organism will evolve. So on a planet with similar conditions to Earth the dominant life form would look similar to us but could have evolved from a reptile instead of a mammal - but would stand upright, have two arms and two legs, two eyes that faced forward and be able to communicate.

Answer 5

I'm not sure where to begin but I'll give this a shot.
There has to be a certain percentage of earth like planets out there but that doesn't mean they will all have life, or if they do that it will be intelligent life.
Then you have to consider what it means to be bipedal. Conditions need to support bipedalism, such as fruit bearing plant life which requires life to stand on two legs for a time in order to reach it. Also, there should be a predator and prey relationship which requires life to stand up on its hind legs in order to see what's coming to eat it.
Then there's the question of large brains. Of all the life on Earth less than one percent of that life has a brain comparable in size to humanity.
And don't forget the opposable thumb either. It allows us to make tools in order to aid our survival.
I find it highly unlikely that life out there looks like it does here to that extent in very many cases, though I would not say it is impossible.
It's a lot to consider. I hope I have provided some insight.

Answer 6

A good chance that their form and function will be similar. We are pretty evolved. That being said, we have a very narrow range of acceptibility for appearance. Consider how you would view someone with a single eye, missing ears, or a nose with a single nostril.

Answer 7

All multicellular life on the planet relies upon a similar DNA molecule and intensely comparable cellular shape. the different possibilities that developed early interior the earth's environment the two grew to alter into extinct, or retreated to especially constrained niches that don't enable for extra progression. So comparable is the chemistry underlying the genetics in contact that there are purely small proportion adjustments interior the genes that define a human and people who define bugs. All this illustrates that once nature reveals a layout that works, nature merely keeps reusing that consumer-friendly layout back and back, and evolution has no want of something notably distinctive. Morphology interior the fashion of head shape, place of eyes, physique shape etc are a reaction of the biology of the organism to it extremely is exterior environment. The exterior environment might favour a particular form or affiliation of eyes for occasion, yet ultimately the extremely affiliation would be a tradeoff between environmental desires and organic and organic risk. for occasion the ambience ought to tend to reason the organism to have 2 eyes, however the underlying biology might make this the two impractical or prohibitively costly. on account that all enhanced organisms on earth have a similar consumer-friendly biology we would assume them to all respond morphologically to the ambience in very comparable strategies. despite the fact that, a planet with organisms based upon a very distinctive cellular biology could be estimated to respond extremely in a distinctive thank you to their environment regardless of if that environment became resembling that on earth. for this reason creatures on a international the place the genetics became based upon a biochemistry it extremely is thoroughly distinctive to earthly biochemistry ought to be estimated to look notably distinctive to earthly creatures. regrettably, at this point we have no theory regardless of if life can flourish with the different style of biochemistry than what's discovered on earth, extremely different than for the undeniable fact that at modern-day there is not any longer even any data of life having arisen in any respect everywhere different than on earth. Cheers!

Answer 8

Slim to none. My money is on none. We have weird enough stuff on this planet from just minor changes in conditions. Chances of another planet having gravity, atmosphere, even little stuff like distance from their star, and it's color, will make whatever we meet, if we ever meet it, pretty strange to our eyes. Ever look at an octopus up close? That's an "Earthling" also.

Answer 9

Very unlikely, the scientists reckon that the chances of another civilisation developing in the same manner as we have is very unlikely. We have evolved to suit the gravitational forces on us, the amount of sunlight we get bombarded by, its highly unlikely that another galaxy will have emerged with everything the same.

Answer 10

I think it's a nice round figure.......zero chance I would say!

We are like we are because we evolved HERE over time, they will be different because they will have evolved SOMEWHERE ELSE over time. It is only Hollywood and Star Trek that believe in 'Humanoid' alien life surely.
