Building on the universe established in this question, what happens to identity verification when someone's physical appearance and genetic code are modifiable at any time? Review of universe rule...
In my alternative universe, Atlantis was a real city that existed, although it wasn't called Atlantis or founded by humans. Atlantis or rather, Dosham was a city on an isolated landmass in the nort...
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...
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...
King Solomon, founder of the Solomonian Dynasty, was the first emperor of China. After he conquered the mainland, he gave his alchemists the single command of creating an elixir that would allow hi...
The Greek gods were sufficiently advanced aliens with access to powerful technology. In the begining of our worlds formation, Zeus created mankind from his own flesh. These mortals were made in the...
The MC1R gene turns pheomelanin into eumelanins but there are another kind of pehomelanin called pheochromes. So if a brunette or black person used a cosmetic gene therapy to turn off this gene how...
I have a species of megafaunal carnivore that are extremely mobile with territories spanning hundreds of square miles and lifespans of 120-150 years. They lay clutches of 2-3 eggs every 20-30 years...
Is there a way for a species to essentially become a living incubator of sorts? Not the other way around, as in Plausible ways for the alien species to be able to impregnate every and any species?,...
Overlord Larmark is a scientist from the 21st century who is interested in world domination, and needs powerful generals to lead his armies. He looks to the ancient world, as only that time period ...
Given that you can travel back in time and have a baby there, or alternatively, send your baby back in time, would it be possible that this baby one day becomes your own mother (gives birth to you)...
A domestic terrorist organization has come to light due to recent terror attacks that they claim responsibility for. This group has developed a biological weaponized plague that attacks the nervous...
I think it will be possible in the far future to take a single person`s cells, genetically enhance and change them using genetic engineering and synthetic biology using new genes, and put it in a 3...
My name is Adolf Palpatine, a kind and benevolent Buddhist monk on the path to enlightenment. I have figured out a way to game the system. By making a deal with a demon, I have gained the ability...
An alien creature has secretly landed on earth, seeking to propagate itself among the local species. It studies the individual sexes of a race called humans and determined that the males would be m...
I am a complete amateur regarding biology, so please forgive me if this question is a little stupid. Could we ever create squids that have human-level intelligence and could serve as a replacement ...
I was thinking for ideas for new species for the planet I'm currently worldbuilding, and it occur to me if there could be a species (humanoid) where everyone looked exactly the same, and if this co...
Why might a species advanced enough to develop genetic engineering start a process by which their own genes, over hundreds of years, would get edited back to resemble their more primitive ancestors...
The following scenario takes place on Earth, sometime in the next few decades. An unethical biotech company has developed a deadly bioweapon that uses humans as a vector, almost like a suicide bomb...
I know that DNA can be used to encode information, using ACGT as a quaternary instead of binary encoding. Could a functional genetically-modified human walk around with a lot of information store...
In my world there is a race of humans who are disproportionately female. They are closely derived from and very similar to real-world humans, but are unable to interbreed with the other races as th...
On the earth today most animals use a two sex mating system where male and female provide the same amount of genetics to the resulting offspring, despite the fact that in many cases the female prov...
Recently I've been imagining living on a terraformed Venus in a distant future. I've a pretty good idea of how this can be done, having gone through many articles on how to terraform venus, so my q...
In this world, time travel is possible, but the only thing that can be sent back in time are thoughts. From the perspective of your past self, you suddenly one moment realize that you have "memorie...
Normally when conducting DNA testing, I presume techniques are utilized to ensure you're just testing one individual's DNA from a sample, even if it is possible that sample was contaminated one way...
If person A has had the genes dictating their sight/ the internal structure of their eyes, replaced by say, eagle eyes or cat eyes. What happens when they reproduce with person B who has regular h...
In my story I have a strain of virus capable of stealing parts of or changing its hosts DNA, so it could copy the abilities in nature for its next host of choice by taking the genes which control t...
On a world made up of many small islands, each island cannot support a very large population. Although sometimes individuals from one island make it across the ocean to another, this is usually a ...

For visual reference: Apes are visual species who rely more on their eyesight than any of the other senses. As a result, they see the world in three shades of color, whereas other mammals see i...
After Cain killed his brother Abel, he was cursed by God to wander the earth forever. On his travels, he met a sympathetic woman named Lilith. They discovered that they had a mutual beef with their...
In a setting with multiple sapient fantasy races (ie, elves, orcs, humans, dwarves), assuming these races could interbreed and this activity became common, would they eventually reach a point of hy...
This question has its origins in the word "dendraphile" used in a YouTube comment. It was used in an insult used by dwarves towards elves. My chain of thought then was that the dwarves would use pl...
In the movie Captain Marvel, the main antagonists (at least for half the movie), the shape-shifting Skrulls, can change their appearance to perfectly match any humanoid creature, down to DNA. Scie...
I had an idea of a concept a while ago. If a planet that for some reason or another had only one giant continent like Pangea, but bigger, for more distinct habitats and giant lakes assuring isola...
I have a friend who is a really nice guy. The problem is that he was born as a half demon. While he looks completely normal, he possesses a spirit inside him called "Amon". This being forces him to...
I would like to use CRISPr Cas9 technology to extend the life expectancy of my fictional civilizations. From what I understand, CRISPr could extend life by lengthening telomeres and improve quality...

In my story the inhabitants of Earth are near extinction. They want to make a capsule of a bunch of human DNA and blast it toward the Andromeda galaxy. They take 1 oz of every blood type still liv...
The Eldar are a psychic species with a similar body design to humanity within a galaxy-wide empire. They are far more advanced than other races, technologically and philosophically. Eldar have a st...
Darwin's hypothetical mechanism of inheritance was called pangenesis, whereby the body continually produced particles of information - gemmules - which aggregated in the gonads, and that that the o...
An evil scientist has engineered a plague that would kill anyone with an xy chromosome pair. This plague has systemicatically spread throughout the planet, killing all males within the population. ...
I'm creating a humanoid species, roughly based on humans. The difference is that not every opposite sex couple of fertile age could produce offspring. The premise of my story is based of some men...
Like the title states, how would it be possible for the same species to live on multiple planets (before space travel is invented)? Basically, a civilization invents space travel, meets aliens, and...
I am in the process of creating my universe, and have based it on semi-hard science. The universe that I have created is quite extensive, and I thought that it would be unreasonable for the only ki...
