assistant: Evolution is a process that occurs over millions of years and is driven by the survival and reproduction of organisms that have certain advantageous traits. The development of wheels as a means of locomotion would have required significant changes to the anatomy and physiology of animals, and it is possible that legs, which are a more versatile form of locomotion, were more advantageous for the survival and reproduction of ancestral species. Additionally, the development of wheels would have also required a hard surface to roll on, which may not have been available in many environments where early animals lived.

assistant: The absence of wheels in nature is frequently attributed to constraints imposed by biology: natural selection constrains the evolutionary paths available to species, and the processes by which multicellular organisms grow and develop may not permit the construction of a functioning wheel.

assistant: Animals were prevented from evolving wheels, some biologists reason, by following dilemma: Living cells in animal's body are connected to the heart by blood vessels, and to the brain by nerves. Because a rotating join is essential to a wheel, a wheel made of living cells would twist its artery, vein, and nerve connections at the first revolution, making living wheels impracticable.

assistant: Evolution is a blind process that is driven by random mutation and natural selection. It is not guided by any particular goal other than survival. Therefore, it is highly unlikely that it would ever come up with a specific solution like wheels, as there are many ways to efficiently move around and survive in the environment. Legs are one of the most successful solutions, as they are efficient and allow animals to travel quickly and navigate obstacles with ease.

assistant: I don't know, though my guess would be that wheels are rather complex compared to limbs and only work well on smooth surfaces.

prompter: Why are wheels a human invention, though? They're simple enough, why didn't they evolve?

prompter: Which animals have been invented by humans?

assistant: Several animals have been created by humans through traditional breeding methods and more recently through genetic engineering. Examples of animals created through traditional breeding methods include the liger (a hybrid of a male lion and female tiger), tigon (a hybrid of a male tiger and female lion), mule (a hybrid of a male donkey and female horse), and beefalo (a hybrid of a male bison and female domestic cow). A few examples of animals created through genetic engineering include the GloFish (a type of zebrafish with fluorescent colors), the Enviropig (a pig with an altered digestive system), and the human-rat hybrid (a hybrid of a rat and human embryonic stem cells).

assistant: Humans have affected the evolutionary path of some animals through artificial selection. For example Dog breeding is a prime example of artificial selection. Although all dogs are descendants of the wolf, the use of artificial selection has allowed humans to drastically alter the appearance of dogs.

assistant: One example of a fictional animal with wheels that has been invented by humans is the "Wheelers" from the 1982 film "Return of the Jedi," which are a race of quadrupedal creatures with wheels instead of legs. Another example is "Wheelie" from the Transformers franchise, which is a small robot with a wheel for a body.

prompter: Thank you for your reply, I'll talk to you tomorrow.

assistant: Animals - organic life. Organic life - everything in order with nature, therefore it's impossible for animals to have "wheels", wheel is primarly a human idea, simple but at the same time complicated, materials, radius, overall shape, the number of spokes or lack thereof... everything points out that animals can't have wheels with their natural evolution.

prompter: But can an animal be a wheel?

prompter: What would nature need to do so that animals do get wheels?

prompter: Can you explain it in terms of evolution / Natural selection, and not philosophically?

assistant: Animals do not have wheels because they are not evolutionarily advantageous for most animals. Wheels are a man-made invention that has specific uses in certain environments. Still, in nature, the ability to move in different terrains and adapt to changing conditions is critical for survival. Additionally, a wheeled structure would require significant energy to maintain and move and would be vulnerable to damage in rough terrain. Evolution has favoured forms of movement such as legs, fins, and wings, which are more versatile and efficient for most animals.

assistant: The reason animals don't have wheels is because they evolved in water and then crossed over onto land, so were already highly adapted for swimming or crawling. All the animals that crossed over to land were segmented and bilaterally symmetrical. A tube shaped colony of cells with sensory organs near the mouth has a direction of travel gives rise to a front and back. Being darker on the top than the bottom evades predators and grants left and right, breaking radial symmetry. One group evolved segments which were then free to specialise developing appendages, which were used to cross over to land multiple times, like in insects, arachnids, amphibians and fish. The ancestors of mollusks developed a foot muscle attached to the head, used to crawl along the floor. So nature didn't invent the wheel because animals didn't roll out of the sea, they crawled.

prompter: Round objects have existed for billions of years, such as the Earth itself. Why couldn't similar round objects evolve for locomotion?

assistant: Hard to evolve, impractical on bumpy terrain.

prompter: Which is the most evil Disney villian?

prompter: Hard to evolve? How so? (Again, be brief.)

prompter: Your answer is too short, write at least 10 sentences that go more in depth in the explanation

assistant: Animals do not have wheels because it is difficult for them to evolve. Animals evolve over time because of natural variation in their genes. Animals that have beneficial variations are more likely to reproduce and so beneficial genes become more prevalent over time. Usually these changes are small and gradual. For an animal to have wheels, it would be a very large change for several reasons. One of these is that most animals have a circulatory system that provides oxygen, nutrients and hormones to the body. In order to have a wheel that rotates on an axel, the wheel and axel must be disconnected so the wheel can rotate freely. There is no clear way for the circulatory system to provide nutrients to a wheel if it is completely separate from the axel. Any veins or other connections to it would become tangled up as it rotated. That is my best explanation as to why wheels haven't evolved in animals.

assistant: My apoligies. Here is a more verbose response to your question:

Animals do not have wheels because it would be very difficult for them to evolve such a feature. The evolutionary process of developing a wheel is complex and would require several mutations in an animal’s physiology and behavior. Additionally, wheels are designed for flat surfaces and are not ideal for use in most natural environments, as they are not able to maneuver well on rough or uneven terrain. Furthermore, many animals rely on physical agility or swiftness to survive and avoid predators, and wheels would not be able to offer them the same level of mobility. Finally, animals would require a significant amount of energy to roll around on wheels, which would reduce their overall efficiency when moving through their habitat.

prompter: Please elaborate on "hard to evolve", which is it unlikely that evolution comes up with such a thing?

prompter: Why is it hard to evolve? Continue answering briefly.
