I hypothesize that any truly advanced species would at some point attain the qualification of autotroph. This would be either as a consequence of evolution, or as a consequence of advancements in technologies that allow the individual species to modify its homeostasis.

Given that, by definition, heterotrophic life is only sustainable when a source of autotrophic life is present, we can conclude an immediate necessity for autotrophic life. As observed here on earth, biological systems are poorly adapted. The inefficient transfer of energy through trophic levels further necessitates a larger population--or at minimal a population with a high turn over--of autotrophic life to sustain a reasonable population of heterotrophs. This being said, any evolved heterotroph that would be willing and capable of performing self modification of homeostasis, would only logically do so to become an autotrophic organism and further its chances of survival.

I would further like to conjecture, as a consequence of my former hypothesis, that aliens are in fact highly probably green.

So given the highly probabilistic tendency of evolved species towards being autotrophic, I believe that there is an equally large probability that such a species would be green. Species can be chemoautotrophic or photoautotrophic. By a similar argument, as observed with biomass and trophic levels, one could argue that at minimal there must be a sufficiently large population of photoautotrophs. The argument could be stated that the tendency for mineral systems to form both, usable nutrients and free minerals for building the minimum compounds necessary to form a living organism, as well as a diversity of energy providing compounds, is, when combined, probabilistically low. It would ensue that, at some point there may be sufficiently free molecules to build or organize a form of living structure, and that the energy required would be delivered in the form of light. To make a long story short, the aliens most definitely must be green, if this wasn't the intended interpretation of the cliche well . . . . . what was the intention? And also why did they become grey?

Future thoughts on the matter:
- when will we be green
- will we develop secondary cell walls

It's highly doubtful that any large mobile complex organism could be an autotroph. They just don't have enough surface area to feed an active metabolism. There is a reason why trees don't move around like tree bread in lord of the rings, photosynthesis just can't provide the energy to allow that to happen. Why would they have to be green? why not purple, red, or brown? we have purple, red, brown yellow and bluegreen autotrophs on the earth already...

[md65536]

Interesting idea.

I disagree though. I think that if it is not necessary to become autotrophic (and it clearly isn't), then it isn't certain that a species will become autotrophic. It may be an advantage, but I don't think autotrophy is a required criterion for being "truly advanced".

Green implies photosynthesis using chlorophyll? Aren't there other ways of obtaining energy? Why wouldn't they be black, and able to absorb a better range of wavelengths? Why not able to change color, and control absorption of light? Why be dependent on light at all? Why not engineer the body to be fusion-powered?

Yes, but it wouldn't necessarily have to derive all of its energy from light. It wouldn't necessarily have Earth-like metabolism. Mobile light-powered creatures are conceivable. As well, it's conceivable that an organism could have multiple energy sources, and is able to survive on light only in some state of reduced mobility and energy consumption.

I think making assumptions about what aliens "must" be like based on what Earth creatures are like, is not very reliable.

That is true.

I think I'd have to have some evidence of that.

Again, it wouldn't be an autotroph then would it?

Neither is making wild assumptions about possibilities we have no concept of, earth life is the only data point we have any other comparison is baseless speculation, they could be nuclear powered but speculating that would be kinda hard to back up....

I agree the hypothesis is "highly doubtful" but I don't think that assumptions based on Earth life either support or oppose it. Though, I suppose terrestrial assumptions can be used against other terrestrial assumptions (e.g. if it's assumed that aliens are like trees, then the argument that trees could not produce enough energy for locomotion is applicable).

I'm not saying that alien life of any kind is plausible, just that the idea is imaginable.

No organism could obtain enough energy for locomotion through photosynthesis exclusively, it would have to be close to 100% efficient, a chemoautotroph might be possible, i am not sure about the energy density for that.

As i said, the efficiency is just not great enough, the energy conversion for light to carbohydrates is just not enough , it's possible it might be dormant most of it's life cycle and store energy to walk around in short bursts but the energy density is why we see no walking trees on earth and I have to assume the same laws of physics apply every where...

That is a machine, it uses very little energy, doesn't have to support a biological metabolism much less a brain...

Natural examples of developmental morphology suggests, that to attain a higher level of efficiency, there will be required a more complex system of delivery. So an advanced species implementing self modified homeostasis would, most probably be developing a more complex system.

In my example I would submit, a combined mixotrophy of, photosynthetic epidermis, and an internal chemo-trophic metabolisms. I suggest that maybe the epidermis could excrete organic compounds quickly enough through the vascular system to critical organs and tissues, while being fed by the internal chemo-trophic digestive system. But, for all intents and purposes, one might even argue that being truly mixotroph, and ingesting when necessary or desired, might be best. A greater variety of cells can provide a greater amount of flexibility.

Proving that the most preferred photosynthetic pigment would be chlorophyll--universally--would be a life challenge for me, so I just won't do it. Maybe they are grey!

Is there a legitimate reason for excluding Billy Meier contact notes and or the research by richard dolan as evidence? If not then you will find that all aliens are not little nor green nor men. Is this a question you really want answered? and thanks for discussing what to some is a very sensitive question.

It relates to what I am presently seeking to research--advancements in human cellular morphology, through application of technology, as a means of maintaining homeostatic functionality indefinitely. It's not an attempt to define what an alien should be, but to more clearly define a goal for our evolutionary future. I am unfamiliar with the works of either of Billy Meier or Richard Dolan but I will make it a point to investigate.

[John Cuthber]

Some of that investigation might not take long

"Beginning in 1975, Meier says he began his official contacts ("official" in that evidence was to be provided publicly, unlike earlier contacts), communicating both directly (face-to-face) and by telepathy with a core group of the Pleiadians/Plejaren, or Errans as he also refers to them (Erra being their home planet), who gave their names as "Ptaah", "Semjase",[9] "Quetzal" and "Pleja",[10] among numerous others. According to Meier himself in the video documentary 'Contact', he says that his first contact with extraterrestrials began on January 28, 1975."

Well I think the original conjecture is interesting and logical and something that I hadn't considered before.

However I'd be more satisfied with a statement something along the lines of: If there exists sufficiently advanced extraterrestrial life, and conjecturing that such life would become autotrophic, and assuming that this would likely entail the use of chlorophyll for photosynthesis, it is likely that some of that life would be green. I think this better captures the multiplicity and enormity of the assumptions that go into the idea.

Well john you do me proud. Using wiki is a bit cheap but u got some major points correct. If you see it through by reading dolan or meier. It will change your view of the universe, if i assume the standard model is pretty much your idea of it. and thanks john

good man for having the courage. Most will not even open a cover or read a homepage of richards or billy's.

Honestly I won't be one of them, but that has more to do with the fact that I lack the interest. There are plenty of incredulous things that I pursue but aliens are not one of them. I am a big fan of science fiction movies however, and aliens in film are always fun!

[Xittenn]

I don't think the primary reason for photosynthetic species not moving is their inability to procure sufficient energy; although this is a restricting factor in how a species that are photosynthetic expresses themselves morphologically. Phytoplankton are photoautotrophic and are mobile! Trees don't move because they are made up mostly of dead cells that are composed of a stiff material called lignin. I can mentally conceive of species that can satisfy the conditions of being phototrophic and mobile. I am surprised that there aren't popular varieties of insect like phototrophs that might carry a butterfly like appearance. Another possibility might be a highly limited wake time.
