Would aliens look like humans?
Is Earth’s DNA unique, or is it a universal constant?
Have you guys ever researched Biocentrism? If not, I strongly encourage you to do so. But if you’re unfamiliar with it, here’s a brief summary of what it’s about:
The theory states that life and biology are central to being, reality, and the cosmos — life creates the universe rather than the other way around. Biocentrism asserts that current theories of the physical world do not work, and can never be made to work, until they fully account for life and consciousness. While physics is considered fundamental to the study of the universe, and chemistry fundamental to the study of life, biocentrism tries to place biology before the other sciences to produce a theory of everything.
The reason I bring this up is because…according to this theory, DNA acts as the translator between consciousness and the physical world.
So if it’s true that consciousness gives rise to the universe, wouldn’t it make sense that DNA would be a universal constant?
Science demonstrates how our physical world has absolute physical laws and rules. These universal laws are all mathematical, but the idea is that mathematically our world manifests itself with such precise laws because it is the most probable outcome.
Again, if you’re wanting to know more about biocentrism or you find yourself with a lot of questions right now, I encourage you to look it up.
So….back to the question….would aliens look like humans? Or would they look totally different than us? Do you think they would be humanoid?
Here’s an interesting article for those interested: http://www.dailygalaxy.com/my_weblog/2011/08/is-dna-random-or-a-universal.html

@chodebalm, it depends. What animals would these aliens have evolved from? What is the environment of their home planet? Would they walk on land, or fly, or be aquatic lifeforms or even amphibians? My guess is that they would at least be mammalian in some way, the most highly developed animals here tend to be mammals.
I am just speculating, but consider this. It appears that more recent organisms have been building on the framework of older organism. This is like saying that the first organisms are like a rough draft and the other animals are DIFFERENT revisions of the same initial draft. As a result most reptiles and mammals are very similar. They usually have 2 eyes, legs, hands, etc. In addition, the development these animals is very similar in the initial stages. So if you look at a cow or a human during the initial stages of development they will look the same!
The idea of building on the organism before it can also be seen in the human brain. The brain has 3 parts the reptilian brain, the limbic system brain and the prefrontal cortex.
So it seems that animals have been evolving in a similar fairly rigid framework. So this means that every new animal is “similar” to the other animals because they all come from a similar basic framework.
So if a Alien planet started from a completely different framework their organism would look completely different from ours.
@brycemason well then yes, they might look different but only if those elements are apart of their genetic make up. we have man made elements that arent apart of us. and unless those certain elements were apart of them. im thinking if they were made of things like us. ie. carbon, iron(blood), and so on. then they would look like us. but if they need a different element to function and evolve then yea, they prolly gonna look different
I’d hazard a guess that we’ve evolved according to the nature of our planet. So if another planet was similar to Earth then I couldn’t see it being that far fetched that we’d at least look similar. But say we were talking an entirely different climate and potentially somewhere where conscience beings aren’t the ruler of their world, then we might find that they have evolved more to their surroundings.
@luzimzo, I get that, but there are only certain conditions from which intelligent life can evolve. It seems that the framework for building life is a constant thing. If the basis of reality is consciousness, and consciousness expresses itself as everything we perceive and experience in this physical realm, then the physical realm must adhere to whatever physical laws are set forth or created by consciousness. So ultimately, everything is the same thing. But I believe the physical conditions necessary for intelligent life would have to be similar if not the same as those here on Earth.
There are specific features that humans and any form of intelligent life that becomes capable of manipulating and mastering their environment need. First of all you need the environment that permits them to experience. Mammals were mostly underground, nocturnal or stuck in trees when dinosaurs roamed, they needed to stay small as a factor for their survival. They could lose predators in obstacles and they were not an attractive meal prospect because they were difficult to catch and there was little meat on them to satisfy a predator. Chasing a possum was not worth the effort.
Then dinosaurs left the scenario and mammals were free to come out and start really interacting with the environment, to experience is to form adaptions. With humans, we were not the dominant predator so this made us move about a lot, experiencing more and more things, a key to our intelligence is adapting to heaps of different situations.
An alien species would likely need such a factor because if a species is safe in its niche, it is not forced to adapt, it is not forced to change environment or experience new circumstances, intellect does not evolve.
Then you have the high protein diet, an abundance of the right proteins that are needed for brain development. Then finally a life form needs the hands to work with, we have the opposable thunbs to grab and manipulate things with, an alien species would need something similar to at least be able to build things that can build fiddlier things.
So precise hands, precise diet and precise experiences are what made us possible. I can speculate that there are likely a number of alternative opportunities, so I could say that it is possible that other species would have a similar history, but at this point it is guess work.
I know that dna can tell us if a species is from Earth or has a common source to all the life we have on Earth http://en.wikipedia.org/wiki/Distant_Origin
i believe here on earth we have a library of many different forms of different parts of our universe, all collectively living here, with man being the dominant/more evolved species.
But i think on other planets instead of the ape being the dominant species and revolutionizing, maybe in another it was the feline, and eventually went thru the same steps like a monkey, evolving and walking upright. I think this is where we subconsciously get all these fictional stories of elves and animals speaking. I wouldnt be surprised if there was a more advanced human looking cat race, with basic human style body but skin is covered in fur instead of singular strands of hair like we all have on our bodies (look at your arm) and their ears would be pointy shaped like an elf for example in stories instead of round like chimps.
In another planet maybe dolphins (which some actually believe to be aliens !) are the more advanced species or theres something like mermaids human type beings underwater in a planet similar to earth but covered in 90-100% water.
Some could be lizard type aliens which many actually believe there to be a kind like this called reptilians!
if you look at the universe, where you are located in it, what speck of dust you are compared to the whole that we’ve managed to observe, how many more planets/stars/galaxies there are out there, its infiniteness, well the possibilies literally are…endless!
@dalniente, It’s a fun idea though, isn’t it?
So if gravity falls apart when quantum theory is applied, what about the many-worlds interpretation of quantum mechanics? I’m sure you know more about wave function collapse and quantum decoherence while my game is just general philosophical ontology, but it implies that all possible alternative histories and futures are real, each of them representing a real universe. Before a successful theory of quantum gravity is made, however, as well as a theory for everything, we can’t be sure if it’s true. :( One can dream…
@linnea, in the many-worlds interpretation, linearity is assumed. The linear formulation of QM relies on a classical spacetime manifold, which breaks down at the Planck scale. So, like I said before, quantum gravity is non-linear. My point was that MWI does not seem to be very promising.
@chodebalm, The answer depends entirely on what you consider intelligence. What if that other species experienced reality completely different from us. Their brains would look different and act different therefore they would not be confined by the conditions for intelligent life.
Evolution is not linear. Things species branch off of other species. What if the dinosaurs did not get exterminated. Could you imagine what type of intelligent life form could be created. Maybe super smart birds or super smart reptilians.
Also remember DNA has made some diverse and crazy things from cats to chickens and it’s still not done. Even if DNA is universal think of the other possible lifeforms it could create on a different planet.
@dalniente, you’re crushing my scifi fantasies :c but thanks for clearing that up. I just have always felt that if you can think of it, it exists somewhere. Kind of like strange porn and the internet.
That kind of thinking puts me in a position to believe that thoughts are real and have power. But if our thoughts are real, then could we be thoughts? Are we real? So if nothing is real then can everything and anything be possible? I’m going to… stop derailing now with my existential mumbo jumbo … but that’s just my stance and why I think that there are other humans out there. If anyone has any more insight for me, please share, or message me to avoid derailing this great topic. :]
Would spirits look like staplers?
How long is a rope?
Just face the truth, you have no idea what an alien would look like, or if there even is such a thing in the first place.
Making things up doesn’t change anything, it’s just imagination, projection, UNTRUTH.
It’s no good, it doesn’t make anything better. Only worse.
@chodebalm, “according to this theory, DNA acts as the translator between consciousness and the physical world.”
That would mean that the founders of this theory know exactly what consciousness is, and where it comes from and how to deal with it.
To my recollection it is still unknown what exactly consciousness is, but I am not familiar with biocentrism, so maybe it explains it. Could you elaborate a little more?
I believe there is life in the Universe, and since the Universe is infinitely large, I am sure there is life that resembles our life.
@linnea, oh no, I’m sorry!
Some sci-fi is great though. The philosophical issues it can break up are often overlooked. I’ve been really into Ted Chiang lately. You can find many of his short stories online, but I bought “Story of Your Life and Others” off of Amazon.
“Dr. Louise Banks is enlisted by the military to communicate with a race of radially-symmetrical aliens who initiated first contact with humanity. Woven through the story are remembrances of her daughter.
The heptapods have two distinct forms of language. Heptapod A is their spoken language, which is described as having free word order and many levels of center-embedded clauses. Understanding Heptapod B, the written language of the aliens, is central to the plot. Unlike its spoken counterpart, Heptapod B has such complex structure that a single semagram cannot be excluded without changing the entire meaning of a sentence.
When writing in Heptapod B, the writer knows how the sentence will end. The phenomenon of Heptapod B is explained by the alien’s understanding of mathematics and Fermat’s principle of least time.
Dr. Banks’s understanding of the heptapods’ writing system affects the way she perceives time and suggests a deterministic universe where free will is exercised by not affecting the outcome of events.”
We’re at fault for frequently anthropomorphizing aliens. It’s possible that we could share similar characterisitcs, but they would have evolved in a different area. It is also very likely that they would have a different “DNA-like” molecule. We’re limited by what we know about life on Earth.
Considering how ubiquitous carbon is (and how much more common than silicon), I’d say it’s very likely that they would be carbon-based. But keep in mind that carbon has four valence electrons; we can’t even begin to comprehend how many possible combinations there are.
@chodebalm i think that they might be the same. seeing as elements of space are the same as elements from earth. So we are made from elements, i would think that aliens might be the same as us because elements everywhere are the same?
