Quick Overview Here's the situation: your species, under directive of your friendly world government, has been informed that all "natural" (aka reproducing like your normally would and having a ch...
After researching many head shaping cultures like the Paracas and proto Nazca it seems there is no adverse affects beyond physical. What would the affects be on a gorilla? Would it be able to funct...
The Apex predator of the Sea of Grass biome from planet Andromeda is mostly bipedal, but capable of facultative quadrupedalism, it has long limbs, powerful claws on its hands and is roughly the siz...
Could a life form that uses superfluids as part of its biology exist? I've read in places that the issue for life outside of Earth and especially the theorised silicon lifeforms is that the existe...
Shapeshifters and mass... ever the bane of realistic science fiction. Basics: Let's say someone is changing shape (for whatever reason, voluntary or involuntary, it doesn't matter for this purpos...
Start with a silverback gorilla, make it roughly three times bigger, assume it's bone and muscle structure is capable of compensating for the increased size: how fast can a thing like that reasonab...
Is it possible for a planetary system to form and support life similar to earth-life inside a region of 'timespace' (which is the space within a black-hole), assuming that there is enough space/tim...
Sort of two questions here, but very related. One about whether a mammal-like animal could evolve to have a chitinous endoskeleton, I guess. Then a question of whether, if they grow horns, that ske...
I have been toying the idea of fusing our white blood cells which search and destroy malicious foreign bodies with artificial intelligence to fight various disease causing pathogens, my worry is th...

While watching Biblaridion's Alien Biosphere series, an interesting point came up: in Biblaridion's fictional world, atmospheric hydrogen sulfide is used as an energy source for chemosynthetic bact...
What possible evolutionary adaptations could you foresee in the sensory organs of wildlife in an environment beset by a nigh-permanent sandstorm? e.g. in the case of vision, ways to protect the ey...
Imagine a plain made of tall grass that sways in a gentle breeze. Everything is a deep green and there is a riot of life sprouting from the black ground. A few days later, the grasses turn brown an...
The boom-bust cycle answer I took for my question: Sustainability of Regular Global Wildfires due to Oxygen Rich Atmosphere pends on the atmosphere being rich in oxygen but poor in CO2. I, however,...
Imagine a spacecraft travelling at very high speeds, say 0.3c. While a crew member could theoretically suit up and perform spacewalking maintenance on the outer body of the ship, will they be expos...
So, dragons. They're omnivores and, while they would be potentially formidable hunters, mostly scavengers. This requires them to be more sparing with their energy. Still, they fly and flight needs...
In an alien world, due to changes in the ecosystem animals that were once mostly arboreal started having to spend more time in open plains, adapting to fill a new niche of grasslands/bush eaters an...
I am trying to make a reasonable augmentations. The settings is post cyberpunk, so the tech is little more advanced. For coolness I would like to have ability to jump around 5 meters high ground-le...
In my story characters can go into perfectly simulated virtual worlds where their memories have been replicated down to the individual neurons and their protien structures. In these worlds time pas...
My question is, how do we make humans more able to resist falls(not just free falls, also normal ones and from a "medium" height, 2-10 meters) and be able to move afterwards, at least for the jumps...
A Gelatinous Cube is a massive, slime-based jelly that haunts underground dungeons, and is composed of an acidic substance which breaks down material. These creatures are unintelligent and crawl ai...
I recently finished watching one of the Star Wars films, the one that features the sarlaac pit. When I saw it, I began to immediately think how such a thing would evolve. The sarlaac pit is essen...
Say I have a race of obligate carnivores (for simplicity, we'll say they're felinoid). They have carnivore dentition, and must eat meat as a major component of their diet, but they can also eat fru...
I'm creating a character who was born after a long period of genetic instability, which created a lot more diversity throughout the human race. I'm planning on making my character excessively small...
Vampirism. There are benefits and drawbacks, but one of the benefits is not aging. Great if you get turned in your early twenties, but... what happens if you are turned earlier? Being turned as an...
Fireflies are amazing little insects. They have the ability to produce a pulse of light without the help of a symbiotic relationship with bioluminescent bacteria. This works via a chemical reactio...
In the story I'm writing, a group of African penguins evolved to be fully upright (instead of having their knees bent like modern penguins). Now some basic characteristics of these "erect pengu...
I'm creating a fictional universe in which several races exist that are very different from each other due to long term separation. One race is specialized for archipelagos and more specifically, d...
I'm creating a fictional universe in which several races exist that are very different from each other due to long term separation. One race is specialized for the tundra, and is subjected to sever...
I was wondering, for a speculative evolution project, what could be the bare minimum amount of organisms the common housefly needs to survive? Could they just feed on grass? Or should I add a flowe...

The eyes with vertical pupils of small cats and some reptiles are very good at seeing better in the dark and avoiding being blinded thanks to their ability to regulate the amount of light that ente...
So, I'm creating a fantasy setting, and because why not, I decided to have giants. Not giant giants, just roughly 2 times the height of a human. Now, because physics is dumb, a giant species would ...
When writing a futuristic story I always try to minimise the impact of computerization. Its rather uncomfortable writig a story when technology is advanced enough that humans arent in a position to...
I'm basically designing a quadrupedal digitigrade alien, which has evolved from a predominantly arboreal animal into a predator with more cursorial adaptations, capable of running fast, but still b...
This is sort of a follow up on my question Could a "multicellular" virus exist? in which part of the consensus was that viruses simply can't hold enough DNA. In theory, could DNA form in a structur...
If we could replace DNA, RNA and the ribosomes in our cells by their mirror image versions, then everything would work in the same way, except that the chirality of all molecules would have been in...
