    In the original series of Star Trek, the show tries to pass off what is clearly someone’s dog with a horn taped to its head as an ‘alien lifeform.’ It’s pretty hilarious to revisit - not just to see the actors make a heroic attempt to stay in-character while carrying this thing around - but also because this unicorn dog doesn’t seem distinct enough from life on earth to make a believable alien.
    But this raises an interesting question: if there is life elsewhere in the universe, just how ‘alien’ will aliens look? It’s a question many scientists and sci-fi authors have speculated on, and is a fascinating rabbit hole to go down.
    So, for this entry into the archive, we’ll explore relevant phenomena in evolution and physics to determine if extraterrestrials are more likely to look like Earth animals, or something far stranger...

      Hey ,I would just say I love the channel. Got recommended the video of Codex Seraphinianus and have been watching ever since. I imagine you don't take recommendations ,but I would like to try anyway. The book is called Arthur Spiderwicks Guide to the Fantastical world around you, and is truly one of the most beautiful books I've ever owned. It details the speculative biology of fey and invisible people and was based on a real person's notes and studies. I have a physical copy of the book ,its not very long but its beautiful nonetheless, but I'm pretty sure there is a digital version available. Even if you won't see this I actually just wanted to recommend something and tell you to keep doing what you are doing. Thanks for all you do.

    Star Trek Next Generation actually covered why all the aliens look similar throughout the different series: it wasn't convergent evolution, it was divergent evolution. Apparently an ancient race had spread the seeds of Life across the galaxy which is why so many aliens look alike and in some cases are capable of interbreeding.

    For anyone interested in imagining human contact with "Alien-looking" sentient life I recommend the novel "Project Hail Mary" from Andy Weir (the guy who wrote "The Marsian"). I think it's an incredible depiction of Alien life and how to cooperate with it to achieve a common goal but also any other ambitions we might have in common with other intelligent life.
    Another fascinating take on Alien intelligence is the "Three body Problem"-series from Cixin Liu. It's also very interesting to see a chinese/asian take on scientific problems that you are maybe not familiar with if you are used to western fiction.

    I read a scifi book once where one of the alien species had developed on a world that was very windy and dusty, and instead of using eyes, they had evolved the ability to navigate using natural radar. Not sonar, but radar, which worked by emitting radio waves. In fact there was a scene I found particularly memorable, where first contact went horribly awry when these aliens accidentally killed a human via too many aliens looking at the human with their radar vision, basically microwaving the poor dude alive.

    In college I decided to write a short paper on alien life and more specifically, inorganic life. That is, life that is not fundamentally based on the carbon atom and water which is what we're used to. As he briefly mentioned in the video, I wrote about silicon-based life and even ammonia-based life as well as planetary differentiations that could lead to very wild lifeforms.
    I also briefly mentioned that because of our innate comfort with "life as we know it," that we may be limiting ourselves in our search for life by casting a smaller net by only scouring for planets and systems similar to our own when in reality, the universe would more likely have no limitations on life. Our very definition of life could also be extremely narrow and limiting by basing everything we know with only that which we are familiar with.
    Anyway, I digress. it was a very basic exploratory paper into the topic of astrobiology and speculative biology, but it led me down a rabbit hole that I have since held a deep interest in. I find the topic of alien life (actual aliens, not as Hollywood and popular culture portrays them) extremely captivating and infinitely interesting.
    Thanks for an awesome video on the topic CA! I love your stuff! Keep it up!

    Life on Earth is so incredibly diverse and that’s why I think it’s difficult for people to imagine a life form that is completely out of the box or like nothing we’ve seen here on Earth. You could come up with ALMOST any premise (habitat, shape, mobility, mating habit, colour, sound it makes etc) and there is an animal here on Earth that does that thing in one way or another (including all of the extinct ones!!).
    We have creatures that dissolve their own bodies to create completely new ones: butterfly. Creatures with insane/insanely different proportions: giraffe, whale, Argentinosaurs (dinosaur), giant squid, bacteria, ants. Creatures with a diverse range of defence mechanisms: electric eel, wood louse/rolly-polly (rolls its entire body into a ball), fire ants, venomous snakes, horned lizard (squirts blood from eyes), skunk, narwhal (it’s basically a dolphin unicorn hybrid lol). Notable mentions to show Earth’s biodiversity: turtles/tortoises (their shell), spiders (their 8 legs AND web creation), stick insect (looks like a literal stick), sponges, jellyfish (just look at them!), humans (their everything lol like language, culture, civilisations, technology etc also opposable thumbs)
    Also, Earth’s deep-sea creatures are pretty “alien” and so insanely different to anything on land!
    To be 100% out of the box completely, an alien would have to be non-carbon based or have the ability to bend space time or something

    A type of evolution was explained to me recently in a way that made me understand it more than I already did;
    Let’s use a moth as an example:
    A bunch of moths are born, and one moth had a weird mutation, or deformity where it had different colored specks on it, which coincidentally helped it hide better from enemies which caused it to live longer, and therefore mate more. Its’ offspring also had the same mutation, which also allowed them to live longer.
    So where the original moths are dying like usual, these new mutated moths are thriving, mating, and completely taking over to the point where the original look of the moths have completely died out and don’t exist anymore.

Yet, several animals on hearth are radially symmetrical and can be cut down the middle in any direction and in the past some animals used to be trilaterally symmetrical (trilobozoa).

We have other characteristics that aren't necessary as bilaterians (such as our suite of sensory organs). It's not inconceivable for radially symmetrical animals to evolve them on other words.
      Furthermore, radial symmetry returned in the echinoderms (sea stars, urchins, and cucumbers). This means that radial symmetry posseses some good advantages (otherwise it wouldn't have been selected for).

Both of these are sea creatures who are out of the running for tech-level intelligence. Can't evolve tech in an aquatic environment. Fire is mandatory.
      As for a reason for bilateral symmetry, I would think that it's easier to copy two halves that are the same than it is to contain the dna code to make two different sides. Not sure what the primary driving forces are but then again, nobody knows all the forces that drive the evolution of a creature.

      Also fun fact: plants of Earth actually reflect a very big part of sunlight. This is exactly why leafs are non-black and some leafs even transparent. Here is a theory that back in days here was a much less bright sun that and most of the photosyntesizing life was somewhat dark-violet and did not produce oxygen. According to the theory of "Violet Earth", green photosyntesizing animals evolved after them, they use light of blue and red wavelength, with was relatively strongly reflected by violet organisms and in the end green life killed almost everything by producing powerful oxidizer as an oxygen. Also, bak in days Sun was weaker, but nevertheless temperature on Earth was somewhat reasonable because of a green house effect from a methane. However, tons of oxygen released by green lifeforms oxidize methane into carbon dioxide, making planet colder and killing almost everything...

      I am very on board with the first three ideas. I think the lithoid one was explored a bit in either the neverending story or something by terry pratchett, i don't remember which one exactly. There, the protagonist climbs a mountain, but it turns out the mountain is actually a giant who is moving so slowly that the protagonist doesn't notice, and the protagonist is moving so fast to the giant that the giant doesn't notice him either. So neither of them even recognize the other as a form of life, just because their experience of time is so different.
      I do think it would take some serious creativity to make plasma based life work (certainly more than i have left over right now), just because a defining feature of plasma is that it's very amorphous. As in it doesn't hold any structure on an atomic scale, you can't form any cells or even have any real way of distinguishing any two parts of it, because the particles all flow very freely. So maybe the entire plasma is one life form, and the flowing particles are like brain waves? One other feature is electrons fizzing around pretty freely in there, so maybe they form the life? One "life-form" is a pattern of movement in the electrons, which maybe competes with other patterns for propagation through the plasma, and somehow displays intelligence? Probably unrealistic, but then again, we don't even know for sure if there's more than one electron in the universe, so i think "electron flow has patterns and is intelligent" still fits within the unknown. Sorry for ranting, but i thought it was an interesting thought.

    I love to explore aliens that are as different as possible but in fundamental ways, like that project where a common ancestor had their esophagus and mouth separate, and all life from then on had two tubes because of that early design difference.
    Or Marvel’s Klyntar, asexual symbiotic organisms that were created as a bioweapon but rebelled. They had very little understanding of anything, but thanks to their sapience and symbiotic nature they often pick and choose what bits of other cultures they like and build off of that. It’s very interesting to see how such a mutable creature views our knowledge and culture, especially basic philosophies we take for granted, like “individual identity”.

    I think alien creature designers sometimes (often) go too far in making their creatures very complicated. Six or eight legs, all sorts of appendages, complicated jaw structures, multiple eyes in awkward locations, and so on. Our body plan may be just our own, but it's so incredibly simple. Two front limbs, two hind limbs, head in front with two eyes (one for each side), nostrils at the front (better to you know, avoid drowning, and also a sense organ), and simple jaws that go up and down.
    We (by "we", I mean tetrapods) have drawbacks and funny mistakes in our body plan, but you can't really get any more simple and versatile at the same time than the tetrapod bodyplan.

      I think niche partitioning within one species is such an underused concept, and actually occurs more often than people think. Similar to your example, here on Earth mosquitoes have separate niches for males and females. The females are sanguivores that feed on large mammals, while the males are pollinators that feed on nectar. Another fun one is niche partitioning between life stages. This is most obvious animals that go through some kind of metamorphosis which can cause significant changes in body plans, diet, and even environment (aquatic vs. terrestrial). However, it can happen in other animals as well. Paleontologists have noticed, for example, that areas known to be within the range of T. rex seem to lack medium-size predators. That, combined with some interesting shifts in proportions of juvenile vs. adult T. rex, suggests that these animals went through a period of time as juveniles where they functioned as medium-sized predators who would chase down their prey, possibly as a pack. As they matured, however, they would develop proportionally shorter legs and stronger jaws, indicating that they were no longer a speed-based predator, but instead relied on their strength to take down proportionally much larger prey.

    Two of my favorite alien documentaries are _Alien_ _Planet_ and _Extraterrestrial_ ; you've already covered Wayne Barlow's masterpiece. _Extraterrestrial_ is a 2-part documentary that covers two theoretical, life-supporting planets: Aurelia and Blue Moon.
    Aurelia is a planet that orbits a red dwarf and doesn't rotate. Half of it is a perpetually dark frozen wasteland and the pole of the other half is a perpetual storm zone, leaving a goldilocks ring between them that supports life in never-ending daylight. The trees are actually animals that crawl along their "roots", which are eaten by six-limbed, burrowing, salamander-like creatures, which are themselves preyed upon by what look like featherless hell-emus.
    Blue Moon is a large moon that orbits a gas giant and has a much thicker atmosphere, which has allowed for truly giant organisms to take to the air. Vegetation grows immensely tall, some supported by a whole intertwining network of stilts, and large ray-like creatures are able to tether themselves to them and remain suspended in the air. The peaceful herbivores are giant, flying whale-like creatures that feed on floating analogues to phytoplankton, and the apex predators are what I'd consider insectoid dragons the size of eagles that operate as a hive.

    Something interesting to consider is that on a planet with no light, it is possible organisms might evolve bioluminescence for one reason or another, which eventually would most likely lead to the evolution of eyes. It would be an interesting planet, as the sight of everything around would be dependent on the will of the organisms in your vicinity, similar to how Earth life depends on plants to keep the food chain going. This would also lead to a lot of optical illusion-based defense mechanisms, I'd imagine. Things would take advantage of the fact the light around them is generated by life, oftentimes food. Predators would probably sometimes evolve to become lit up and thus fit with the environment, while others would evolve to lack any bioluminescence, forfeiting the ability to see when outside densely populated areas, but gaining the ability to hide in shadows. There could be entire colonies of organisms that shut out the lights when a predator is detected, and chase out any organisms that don't follow this method, leaving the predator in the dark and unable to hunt efficiently.
    Heck, some primitive photosynthesis-like processes might even happen in areas with abundant enough, and glowy enough, lifeforms. Maybe it could be symbiotic, even.
    ...maybe I should just write a spec evo project about a bioluminescent planet, because I clearly think about this a lot.

    This assumes, of course, that we are talking about terrestrial life. But we don't even know if other life is even possible. With silicon, you have so many problems that make a carbon-based analogue of life virtually impossible. Hardly any double bonds, a polarity reversal with hydrogen and too strong bonds with oxygen would require completely different environmental conditions than on Earth.
    And life like on earth only seems to be possible under our very special conditions. A surprisingly calm yellow sun, a medium-sized planet in the habitable zone with neither too much nor too little atmosphere, a rotation that creates a strong magnetic field and arguably so much more. Even chemistry seems to have so many unknown components that we have not yet managed to create life from elements.

    For the purpose of writing tho, the objective is usually the story telling, so if more generally human relevant alien form creates the universe that allows your objective to be achieved then, the principle of less is more always holds... then if you plan to create something that is more of an adventure into the unimagined, well, go wild and stride far, the boundaries are where you decide them to be...

    I’m holding out hope that we catch a glimpse of extraterrestrial life before I pass away, I was listening to the part about how our visual organs are represented to us as eyes and I thought, what if their visual organs are just completely different in function and design yet serve the same purpose
    Edit: that goes for the rest of their bodies, I want to see how they get around and communicate, and I want it to be jarring and odd to us

    Imagine multiple Earths, all perfectly identical. The sun, the moon, the tilt and all the neighboring planets are the same. How different would the lives on those Earths are? Maybe Earth 1 is red, Earth 2 has no life, etc.. It's just fun to think about.

    In sci-fi YV and films where’s actors are used, there is obviously a limit. I thought Doctor Who did a good job with the Hath in the episode The Doctor’s Daughter. When it’s just make, it falls down when different coloured skin meets a red tongue and the throat.
    The ‘prawns’ in District 9 were vaguely humanoid in that there had a head, two stems and two legs. But brilliantly imagined nonetheless.
    The various alien species described in Rama valine’s 2-4 are perhaps the most inventive. Would love to see that brought to the screen. CGI is now at a state to name it believable on screen.

    I like really out there alien designs but I am willing to give a large amount of leeway in how alien Xenos in SF are particularly if they are in live action properties or multimedia properties that could do live action in the future for practical considerations. It is a HUUUGE ask to have an expensive SFX shot for literally every appearance of an alien or requiring 12+ hours of makeup for cast members; that consideration puts a large pressure on creatives to reduce the amount of non-humans are on screen. I am willing to deal with rubber forehead aliens with some skin paint if it means having more aliens in my SF properties.

    I was recently re-watching James Cameron's Avatar and it's a movie I love for personal reasons but I then watched Trey the explainers video on the biology of Pandora and makes it interesting how well designed the life on Pandora is of course being done by the same author of Darwin IV. But I specifically was curious if sapien aliens like the Navi exist and how the Navi have nostrils while every other lifeform breathes through chambers on there shoulders. And the Navi are near human but distinct enough. He didn't mention how the Navi's hair is the only hair on their body bit also is connected to their brains and spinal cords and is the explanation for why everything on pandora cam have these neural links with each other.
    Mass Effect has some interesting sapien alien designs.

      All the lifeforms on Pandora are fantastic except for the Na'vi, which are essentially taller and bluer humans, but it's understandable that they had to make them look human for cinematic purposes. If they were looked like giant mantises, they would have been hard to root for.

      @@isaacbruner65 they are humanoid superficially human like but I disagree with most of what you say i do not see them as tall people. I think the Navi are well designed somewhat believable for a human like convergence species. Especially compared to other sci-fi I love like Star Wars were certain species are just humans with vibrant skin tones. Though there's an in universe explanation of that.

    I think the primary question is whether the basic body plan that we hold will win out as top species regardless of wherever. For example, octopus might be great at pressing buttons to fly a starship. But without bones, what would he be able to build without being able to lift things?
    I learned at Univ a long time ago, that exoskeletons limit the size an insect can get, since there would be a point at which the muscle mass needed to move the exoskeleton would be greater than what could fit inside. (I do not know if that idea is still valid or not but it's what we were told.) Now maybe a weaker gravity will do the trick. Except that if an internal skeleton has an inherent advantage over an external one, then it might not matter that the gravity is weaker as the internal skeleton might still win out on such a planet.
    So while we cannot rule out that technologically advanced species could have a radically different body plan to us, it should not surprise us if they don't.
    Unless of course, they are interdimensional beings in which case all bets are off.
