You need to constantly threaten those humanoids from the back - for example big silent owls and manual tasks that require a lot of time The eyes need to provide an advantage for these humanoids, s...
Humans are yummy They prefer the taste of human flesh over the flesh of rodents that crawl around everywhere. Especially when munching on humans that are well off and can therefore afford to be cl...
There is exactly one important cell - the Core The Core is what coordinates the super-healing. Every other cell is unimportant and will simply die when cut off from a "normal" body. They can't rea...
A common misunderstanding about theories in general is that you can prove them, when in fact you will never be able to prove a theory - you can only ever falsify a theory. There is simply no way to...
We give the minds some hobbies to do We have lots of people who have literally nothing else to do than think. That will probably be boring for quite a few of them. Why don't we put them to us-... ...
Money - a very macabre version of streaming You could for example make a live television show that sends every duel happening across the world. Think about it like Twitch where you can watch peopl...
Time flies are attracted to temporal paradoxes. The name implies a small fly, but in reality they are brutal, quite big and carnivorous. Ever wondered why there are no time-travellers around? Gue...
The problem is that a simple head won't fly - it needs some wings. And that is exactly where those "entrails" come into play. The "entrails" are really a form of wings that allows your creature t...
Spaceships are not supposed to withstand a lot of external pressure Have a look at our sister site Space.SE and the question Do spacecraft have similar structural integrity requirements as submari...
Your dragons are vegetarians and have a lot of different stomachs - just like cattle To cite from the Wikipedia article on cattle (emphasis mine): Gut flora in cattle include methanogens that ...
It's called cleaning symbiosis This is definitely a viable idea. To give you some information from the linked Wikipedia article: Cleaning symbiosis in our nature Cleaning symbiosis is a mutu...
No, this would not work The problem is the angle at which other creatures, such as your astronauts, are looking at the creature. The far closer lights from the predator would appear to change thei...
Mutation Starting from our current evolutionary state the first step is a sudden mutation to have some form of tail again. This one can be very small and doesn't need to have any real effect. Se...
Maybe the Pixies could write on a piece of paper. For them it would be a big painting and for humans it would be a tiny note, but we would be able to read it. This kind of communication might tak...
If I genetically modified a human to have a foxtail of roughly 1 metre length through the use of handwaved genetical engineering - would this have an effect on his diet? Of course an additional ap...
Magnets For some reason your aliens developed a strong magnetic field that they are constantly emitting. Your humanoids use this to attract prey, either by forcing them directly through the magn...
Sexual Selection Downward facing ears can be a problem. Thinking about Beagles long floppy ears can mean that there is not enough air circulation and the ears can get infected. If something makes ...
They want people to strive for a better position and sort the weaklings out By making the lower ranks wear red they incentivise people to get better. After all everyone knows that Redshirts die mo...
I would like to genetically modify a human being in one concrete case like I did in other parts of my little series of How would it affect a human to suddenly... This time I would like to add a pre...
Earthborn people are of lesser value because they were born on a planet that's almost depleted its resources leading to less genetic modifications They may be similar to Starborn people, but their...
For science - just to see whether we can really do it or not Making an air filled habitat for normal humans is boring. That would probably work if your technology is on a level like the one you de...
I love chocolate. Today, when I was making myself a cup of hot chocolate, I was thinking about Easter and about all the chocolate I am going to eat. And at some point I was wondering: How awesome...
This cat looks like a normal Maine Coon to the unsuspecting victim. Except for one little detail: Red claws that inject a neurotoxin into the victim onpon scratching it. What would be the most app...
There are many theories about how teleportation could work (warning: tvtropes). One of them is that the body is completely disassembled on a molecular level and reassembled at the target destinatio...
It could be similar to the existing carnivorous plants that we already have on our planet. This way the plantimal could try to lure its food into its mouth and then slowly digest it. All you need...
