I have got a fictional universe, where a humanoid lifeform evolved on earth not from apes, but from bears. The humanoid bears are like humans; they walk on their legs only, wear clothing, have vari...
Humans as Ambush Predators Homo sapiens and many of our ancestors practiced a form of hunting known as persistence hunting where we just walk after an animal till it keels over dead from exhaustio...
If the gravity on earth was different, how would our bodies change? For this question, assume that gravity was five time stronger (5G) from the beginning of the Earth. Would a human-like body stil...
Imagine a species that evolved almost identical to our own, except for one difference. A child's sex is not decided by the presence of a Y chromosome, and all embryos have the potential to evolve ...
This is connected to a previous question, found here: Realism of a setting with several sapient anthropomorphic animal species Presume that due to outside interference with evolution, a planet has...
They say that nature abhors a vacuum, but could life evolve to live in one? Alternately, could life be engineered to exist on a planet with no atmosphere, even if there is no biologically feasible ...
Think about a scenario in which, on a given planet, a complex life form has already evolved. In your opinion, what are the odds, for this complex form, to evolve towards intelligence? With the...
I'm looking for a very grounded evolutionary justification for the existence of a hermaphroditic sapient and social species, preferably roughly mammalian but not mandatory, which is not as easy as ...
I would like to have a humanoids with three pairs of eyes placed on the same horizontal plane like in Protheans not one below the other like Batarian. I was thinking of one pair being sensitive to...
I recently came up with a lizard that had a sort of crystal-gem like attachment on its back. The problem was finding a way for such a thing to have evolved to have a largish crystal on its back. ...
In a million years or so, descendants of humans (intelligence comparable to wolves) are driven into caves due to competition with land and resources from descendants from alligators and crocodiles....
Suppose human beings have evolved markings covering the face and hairs. The cells contain a colony of bacterium capable of producing multiple arrays of visible light. Each bacteria reacts differen...
Ignoring the tails humans already have. Let's say it's the year 2016. Merpeople exist. They live in the ocean or rivers, breathe air, and have to surface occasionally. They also evolved from earli...
For all who are unaware, synesthesia is a condition in the brain where two or more senses are connected; for example being able to see sound or hear color. Of course they do not actually see color ...
Disclaimer: This question is the third of a new series of questions of mine about introducing hexapeds to the fauna of my conworld. There are/will be other questions addressing i.a.: characteristic...
How to get humans that can change their skin color? Approximately 1.6 million years ago, hominids lost their hair and gained dark skin (so says the New York Times). Evidence shows several several...
Satyrs, fauns, pan, and even the devil are commonly depicted as humanoid bipeds with goatlike unguligrade hooves for feet. However, common as such beings may be in fantasy and mythology, I have bee...
The concept of a planet with several anthropomorphic sapient species (furries, if you will) is immensely popular. But would it actually make sense in the first place? I am aware of the issue of "...
What would be the evolutionary setup for flying monkeys to evolve. They should have branched of from the same ancestors as present day monkeys.They need to be migratory like modern day migrating bi...
Of all the creatures in Hatjörn's dominion, there is none as peculiar as the Murinae Spirita, the mean booze-rat. A vermin so resilient that has developed the most wondrous means of defence and...
How would I change the evolution of humans to result in horns on humans as a result of reproductive fitness, instead of social fitness. Meaning, NEITHER "Horns are sexy", or some strange infection....
In how smart can I make ants, an idea was suggested, to instead of making each ant individually sapient, make the 'anthill' as a whole sapient; a kind of unconventional hive mind. Just as a familia...
Is there any way a catdog (like from the television program Catdog) could survive? If it could survive could it evolve? Are there any reasons it couldn't?
Cobaltduckworlda has had somewhat of a similar biological past as earth, but not exactly. As examples, sentience has happened multiple times, and not just in primate-like species. Beasts that did...
I recently decided to revisit an older scenario I came up with, Ant-hill world, but I have been hitting roadblocks, both old and new. One of the bigger roadblocks is the evolution of such an odd mu...
What many people mayn't know is that there actually three basic types of algae: Green algae, the origin of the kingdom Plantae Brown algae, found primarily in kelp forests And red algae F...
How would intelligent lifeforms evolve bio magnetic resonance imaging? No bionic components or any other prosthetic technology is allowed, how can I extend the ability to see through dehydrated obj...
Under what circumstances would a species develop an adaptation to employ surrogate wombs of their own species or others? The species implants its zygotes/eggs in the uterus/brood pouch of a surrog...
With all this talk of Alien Lifeforms over the past few weeks, I have been pondering a small question. May be a simple yes, no answer. May not. Can a species accidently uplift another species? I s...
Could something like, say, elephants losing their trunks or avian species losing/gaining the ability to fly happen in just a couple hundred thousand years or would it take millions?
In my world, instead of mammals, birds have become the dominant order. Similar to how Quadrabirds replaced the grazing mammals; Aquabirds will take up the niche cetaceans occupy. My goal is that t...
In the world I am designing, instead of mammals, birds are the dominant species. In this world, replacing the niche of deer gazelle and cattle are a group of animals known as Quadrabirds. These are...
On our own world, following the fall of the dinosaurs, mammals became the dominant class. This was caused by a cluster of factors, such as the rapidly changing temperatures and their ability to ada...
In a species I am designing, they have eyesight similar to a cats, their vision at a distance is excellent, but the closer you get, the blurrier the vision is. One solution I had for this was for t...
Currently coming up with a race that lives on floating islands. They are a still primarily stuck to the ground and I intend for them to be able to fly. Or else they are really gonna be stuck on tho...
Gliding is a relatively simple trait to explain in a species' evolution, much quicker than flight or becoming aquatic. But what environments support an animal in the evolution to flight? For exam...
In this context, my world assumes an infinite universe so parallel Earths are possible and probability isn't an issue. My planet has half the gravity of Earth but an atmosphere 12x denser, although...
Certain aphids and mites reproduce by telescoping generations, but do so in different ways (parthenogenesis and intercourse in utero, respectively), Hypothetically these methods could be combined....
Imagine a species almost identical to humans, with one exception. All sperm contained both X and Y chromosome, and every child has the potential to develop as either sex. However, the mother has ...
We have talked about hive minds a lot here and relatively recently, a new idea of hive mind has become popular; the collective consciousness. The basic run down is that a collective consciousness s...
So, this world I've got in my head is inhabited by plant-beings, all of whom are constantly connected to the Garden, a kind of physical heaven, through an all encompassing web of roots, tree brains...
I'm trying to create a habitable planet but with a low atmospheric pressure, similar to Mars. But instead with 15 percent of Earth's atmospheric pressure, what traits can I give my animals so they ...
Two vastly dissimilar organisms turn out to be the same species upon gene sequencing. In this hypothetical animal species one or more components of the life cycle is a fungus, algae, plant, lichen ...
I have a more or less primitive (They can not talk to other races nor was any encoding or morsing or smoke signals invented) alien race the MLPARs (10000 individuals), which was parted in half and ...
So Murlocs. I'm referencing Murlocs from World of Warcraft since I never actually found any other novels or games that have them. Described as a bipedal, amphibious, intelligent, aggressive[Still ...
Given the chance to bring back from the jurassic any plant, which one would be the most adapted to survive and spread in our actual environment?
I was thinking of a sci-fi story where a large population of human beings (let's say anywhere between hundreds and millions) live on a planet with robot guardians. But after a certain amount of tim...
If a tribe of homo evolves into a wild animal that doesn't resemble at all a hominid, is there any chance for this animal to evolve back to the original humanoid shape through atavism/other means? ...
Since we're dealing with cat-folk already with the question about the Khajiit, I figured we'd toss a different evolutionary lineage for furry humanoids around, that of the hyena. Ever since the ea...
Short question, what events would induce the evolution from hands of 4 fingers and 1 thumb into hands of 2 fingers and 1 thumb like the hands of Yoda in Start wars?Would be 2 thumbs and 1 finger be...
