I have been looking at various animals that have evolved some level of aerial capability, and I came across Kuehneosauridae. Reptiles which evolved gliding struts, attached down their sides, which ...
I was thinking about how there are some instances of convergent evolution between marsupials and placental mammals and was thinking about a parallel universe in which there is convergent evolution ...
Is it possible that a complex humanoid creature to somehow still use Mitosis as a method for reproduction, and if so, what would it look like?
What would happen to a human settlement on Earth, on some deserted island, that had no contact with the outside world for a thousand years? Something like a human version of the Galapagos islands, ...
Isogamy: "sexual reproduction by the fusion of similar gametes." Not to be confused with Isogyny, "marriage between people of similar status or age." All such species on Earth lack tissue-level or...
So, according to Other blood colors it is entirely possible for other blood colours to evolve based on what base they use, but why? What would be the benefits of these different bases? What purpose...
Introduction: Welcome to a world where hominids developed to have two different sized hands (similar to the male fiddler crab). We have developed societies, art, and naturally war. But, how exactl...
I was thinking of an organism that lives its entire life in outer space. It would be shaped like a rocket and have skin to pressurize its insides so that its internal organs are pressurized even w...
____________Useless Backstory_________________________________________________ In my world, A hurricane has washed a group of 8,000 pachyderms off of Afro-Eurasia and onto a large island cl...
I've had a great idea to leap over the giant boundary of respiration when making giant insects.The largest problem is that insects rely on diffusion through exterior holes (spiracles) to breathe, a...
Merfolk can be easily described as humans with the lower half of fish. On this site we have discussed; How their tails work, How they sleep, And how they hear. But there is one question that has no...
Recently there have been up to two habitable planets discovered around the star TRAPPIST-1, if animal life was able to evolve on either planets how would eyesight evolve under such a dim star? How ...
I am working on the development of a humanoid species. I figured they'd have split along the evolutionary chain around the same time as humans. They'd live in a warm climate, resulting in little ha...
In the animated movie Monsters Inc. the monsters which populate the universe all look very different despite the fact that they are presented as being the same species (since they can interbreed). ...
It makes sense to believe life is more likely to evolve on the surface of large objects like planets, moons, and asteroids. However, a common fantasy trope is the massive space creature: some kind ...
In our understanding of mass extinction and adaptive radiation, we have found that life can't and doesn't bounce back right away. They take time. It took life eight to ten million years to recove...
Is it possible that a monkey-like creature, in the mountains, could evolve to have no legs and a really strong set of fore-arms? I was thinking that this might be possible because of the climbing s...
This is based on the notion of adaptive radiation, a process in which organisms diversify rapidly from an ancestral species into a multitude of new forms, particularly when a change in the environm...
It seems that my ability to create interesting creatures is limited by the need for sexual reproduction, which is absurdly useful, but also rather limiting, method of sharing genetics. I acknowled...
This is a question I've been thinking about for a while now. Dragons are, by all observances related to the reptile family, (or maybe lizards) either way these are cold blooded animals. Common ...
Thousands of years ago, human domesticated wolfs and from this domestication came dogs, one of the most varied species on earth. This occurred through simple genetic manipulation and forced evoluti...
I would argue that ants are one of the most dangerous, effective and successful creatures on earth. But as we know they are not the dominant form of life. They also vary through-out their many spec...
I just wanted to know something relatively simple. What evolutionary factors could lead to an alien prey species to develop human like intelligence, and by prey species I mean a species like bunnies.
Humanity survives long enough to create a Dyson-Ring around old Sol using many of the planets and asteroids currently in the system. Then 'something happens' we die out, we discover a way to trave...
Assuming a genetic engineer possessed sufficient knowledge and facilities, could they design a highly infectious Retro-Virus or Adenovirus, which would drastically increase the rate of random mutat...
I came up with an alien species that has the following reproductive life: They hatch out of eggs, tended by their mothers, and by the end of the first year (about two Earth years long) they are ...
There have been a few questions about an intelligent avian species lately and they have gotten me thinking. It seems to me that it would be hard for an avian species to evolve to be more intellige...
For the sake of the question, assume conditions are Earth-like in all manners other than those which would be required to spur the development of such a plant. I want the plant to gestate in the di...
Suppose we have a group of organisms (I am not sure if its a society). These organisms are characterised by their ability to reproduce within themselves. That is, every member of this society can ...
Watching E.T. I was wondering what evolutionary factors could cause a species to have the appearance of E.T., like the environment he would likely live in and the gravity of his homeworld.
For the following stars -A Class -F Class -G Class -K Class -M Class What are the most likely skin tones for each type of stellar class? Also for their eyesight how different is it to vary ...
Imagine a world much like ours, except our ape ancestors decided they liked the trees and never climbed down and decided to try out these 'tool' things. sapient apes never evolved. Instead a pred...
The (female) human body is pushing the anatomic extremes to support, later bear and nurse a baby while maintaining upright posture and bipedal walk. I cannot see a way to realistically make pregnan...
An improvement of this: A Completely Different Kind of Reef Which I couldn't delete because it already had answers, and deleting an answered question will dock me some reputation. Today's reefs ...
Given the existence of neon kittens with: the internal properties and mentality of normal kittens bioluminescent fur. What evolutionary process outside of intentional human breeding/gene manip...
On a world like Venus, where the surface is unlivable , would it be possible for life to evolve in caves? And if so , is there any reason for intelligence to evolve in a subterranean organism?
Could underwater creatures with the intelligence of human cave men or possibly the intelligence of apes create technology (that is, more complex technology comparable to what we have now rather tha...
Exhibit A: The apex predator of my world, one that can both fly and swim under water. This deadly monster employs 4 limbs - they act as wings in the air, and fins in the water. It hunts for gam...
Specifically trying to create an alien species that can survive most environmental stressors and find a way to create an environment that justifies the species developing its characteristics that a...
With technology it is possible to detect Gravitational waves as Gravitational waves have been detected by LIGO. Could a species evolve to have a sense organ for detecting Gravitational waves? Wha...
I am creating a hypothetical race of aliens native to a planet orbiting an F class star; the mass of the star is 1.50 (M☉). Would this star live long enough to allow the evolution of intelligent ...
Background Information As we all know, life as we know it today is caused by the process of natural selection, sometimes referred to as survival of the fittest, as proposed by Darwin. Essentially,...
An aquatic creature made of a yellow goo moves through the water by moving its body like a squid. The goo can slowly dissolve small creatures and the planet's form of seaweed/kelp. It also has an a...
Linked: What would conditions on a methane world be like? Question: As mentioned in the linked question, Titan is the second most likely world in the Solar System to harbor life. One of the answ...
It's typically regarded that life needs liquids of some kind to evolve. But liquid is just a state where molecules can move around freely in order to interact with other molecules instead of being...
Continuing from this question: The rodents on the synthetic planet ( which I am now calling Ark ) can now walk/run erect when desired. The scientists continue with biological forging and work on t...
It is well known that our working memory (in our brains) is limited to about 7 items, the magical number 7, + or - 2. This is the Miller's law. (our working memory is not at all like the RAM of a ...
A space colony that resembles the design of a Stanford torus generates artificial gravity by centripetal force. Discussions about benefits of such fake gravity can be easily found: no more constan...
Following up the ideas given in this question, we introduce a new gas to the mix of air. Meta: Assume an Earth-like planet. The proposed change is a pre-development change (meaning it's there sinc...
In a couple of games, you encounter a creature or two that regrows limbs immediately after losing them, not necessarily the same kind or aesthetic of limb. You shoot the creature, it loses an arm, ...
