No, babies are not born with gills and tails. These are traits that are unique to certain species of animals, such as fish, amphibians, and reptiles. Gills and tails are formed through embryonic development and help certain animals to survive in their environment.
In humans and other mammals, however, gills and tails are not necessary to survive and are not present at birth. For mammals, the embryonic stage involves the development of lungs and other organs in order to take in oxygen from the air, enabling survival outside of water.
Babies also do not come with tails, but instead develop arms, legs, and other body parts which are adapted to their environment.

How do babies breathe in the womb without drowning?
Babies don’t actually breathe in the womb until shortly before they are born. Rather, they obtain oxygen via their mother’s placenta, which is a membrane loaded with tiny blood vessels that are responsible for exchanging oxygen and other nutrients between the mother and the fetus.
The baby’s umbilical cord connects them to these vessels and is their primary source of oxygen up until the moment of birth. Because the fluid that surrounds the baby in the womb – amniotic fluid – is sterile and consists mostly of proteins, lipids and other proteins, there is very little risk of the baby actually drowning while they are in their mother’s womb.
Can babies breathe underwater?
No, babies cannot breathe underwater. In order to breathe, we need oxygen, which is available in the air and not in water. When an infant is submerged in water, their body instinctively holds their breath in order to protect their lungs from the water.
Unfortunately, an infant does not have the ability to control this reflex and so the lack of oxygen can cause drowning, even in shallow pools. Babies should never be left alone near a pool or any body of water and should be closely supervised at all times.
Is it possible for a human to have gills?
No, it is not possible for a human to have gills. Gills are organs specialized for aquatic respiration, as they extract oxygen from water. Humans, however, are terrestrial mammals who breathe with lungs, not gills.
Gills are found in fish and other aquatic animals, and they allow them to extract oxygen from the water so they can survive and breathe underwater. Humans, however, aren’t adapted to breathe underwater.
The only way humans can breathe underwater is by using some sort of artificial apparatus, such as scuba gear or a rebreather, which allows them to breathe oxygen from the air inside a tank. Without the use of this equipment, breathing underwater is not possible for humans.
Can people develop gills?
No, people can not develop gills. While some science fiction stories have depicted humans growing gills, that type of adaptation is not possible in real life. While humans are capable of evolving, this process typically happens over thousands or even millions of years.
Humans have not been on the planet long enough to experience any evolutionary changes that would allow them to grow gills. In addition, gills are unique in that they require a large amount of specialized anatomy in order to function, making them impossible to “grow.
” If a human were to try to breathe underwater without gills, they would likely drown due to the lack of oxygen and the inability to expel the built-up carbon dioxide in the bloodstream.
Can humans be given gills?
No, humans cannot be given gills. Gills are a specialized organ used by aquatic animals to extract oxygen from the water and take it into their bloodstream. It works by moving oxygen-rich water over a series of delicate, highly-vascularized gill filaments, through which the oxygen can be absorbed.
Humans do not have this organ and even if they did, they would not be able to extract oxygen from the water in the same way as fish. To obtain oxygen, humans need to breathe air. Artificial gills have been created, which use compressed oxygen tanks and advanced filtration systems to extract oxygen from the water, but these are not suitable for human use.
They are used mainly for deep-sea divers, who require a pressurized environment in order to stay underwater for extended periods of time.
Can humans evolve to live underwater?
No, humans cannot naturally evolve to live underwater due to the physiological differences between us and aquatic life forms. Our bodies are designed to survive in an environment that is generally atmospheric with an oxygen-rich atmosphere, not in aquatic conditions, which tend to be very different.
To survive in water, a mammal’s body must have certain adaptations and features that human beings do not have. These include the ability to extract oxygen from water, specialized organs called gills, efficient skin hydrodynamics to resist water pressure, and body shapes and buildings suited to increasing swimming efficiency.
Additionally, humans already have the capacity to go underwater, but not permanently, as our bodies are not adapted to the environment. With all these factors considered, it is virtually impossible for humans to evolve to live underwater.
Did humans evolve from fish?
No, humans did not evolve directly from fish. Although our distant evolutionary ancestors lived in the ocean, modern humans did not evolve from fish. It is more accurate to say that humans and other land mammals evolved from a common ancestor that lived in the oceans about 530 million years ago.
At that time, the earliest known vertebrates, a group of animals that includes fish, were just starting to emerge. Over millions of years, a number of these vertebrates began to evolve on land. This group eventually split off from other fish and began to develop the characteristics associated with modern mammals, such as warm blood and the ability to give birth to live young.
It is likely that the closest living relative to the ancestor of animals like humans (specifically, a group called synapsids) is a creature called the coelacanth. This fish evolved about 400 million years ago and is still alive today.
Despite the fact that coelacanths are fish, they are believed to possess some of the traits that were found in the common ancestor of mammals. Therefore, while humans may not have evolved directly from fish, they still share some traits with them due to their shared ancestry.
Is there a person who can breathe underwater?
No, there is no person who can breathe underwater. While this may seem like an impossible feat, it is not completely out of the realm of possibility. Through various medical procedures, people can learn how to tolerate much lower than normal levels of oxygen, but this is not the same as actually breathing underwater.
As of now, humans can not survive underwater without the use of diving or breathing equipment.
What do human gills turn into?
Human gills do not turn into anything — they do not exist! Gills are a feature of aquatic animals that allow them to extract oxygen from water. Even though some people have claimed to possess gills that allow them to “breathe” underwater, this is not possible for humans.
The air-breathing lungs of humans are well-suited for living on land or in the air, allowing them to absorb oxygen dissolved in the air.
What did gills evolve into?
Gills, which are organs that allow organisms to breath under water, evolved into lungs over the course of millions of years, likely in response to the drying up of shallow lagoons and other bodies of water.
During this process, some of the earliest four-limbed animals, known as tetrapods, adapted over time to use their newly designed lungs to breath on land. Scientists believe this transition from water to land likely happened around 400 million years ago.
Prior to this, the fish-like tetrapods remained in the water and used their gills to breath. However, as the environment of Earth changed, so did the early tetrapods. By using their fins as limbs, these creatures were able to move from the water to land, and as they did they no longer needed to rely on gills to breath and so developed lungs in order to survive on land.
Over time, these basic organs evolved and further developed until eventually humans inherited a highly complex set of lungs that are vitally necessary for normal bodily function.
Do humans have gill remnants?
No, humans do not have gill remnants. Humans are terrestrial creatures and do not have gills, which are required for aquatic animals to obtain oxygen from the water. While we do have slits in our neck, which some people have mistaken for gill remnants, these are most likely just a byproduct of the same embryological process that develops gills in fish and other aquatic animals.
Specifically, these slits are known as branchial clefts, which are remnants of the tissues that form during the early stages of development in all vertebrates, including humans. Aside from these branchial clefts, humans do not have any other vestigial structures or organs in our bodies that could suggest gill remnants.
What happens to pharyngeal gill slits in humans?
In humans, pharyngeal gill slits are remnants of a very early developmental stage of embryos in many vertebrates that develop in amniotic egg-laying animals. During embryological development, a structure known as the pharyngeal arches form in the mammalian embryo.
This forms an outlet for blood vessels, nerves and other structures which form the slits. As the embryo develops and matures, the pharyngeal arches, and with them the pharyngeal gill slits, close up into the structures in the adult human body.
The pharyngeal arches ultimately develop into other structures in the body, such as the jaws and inner ear structures. In rare cases, people have been born with pharyngeal gill slits that are partially or completely open due to a developmental anomaly.
In such cases, medical experts tend to refer the individual to an appropriate specialist to determine the cause and necessary treatment.
Why can’t we recreate gills?
Gills are organs made specifically for extracting oxygen from water and using it for respiration. They are able to do this by allowing water to flow through them and pushing the oxygen in the water into the circulatory system.
The structures of the gills are incredibly complex and unique, composed of hair-like structures that are incredibly efficient at these tasks. This complexity makes them extremely difficult to recreate, especially in a way that reflects the natural function which has been honed by evolution.
Not only are gills incredibly efficient at absorbing oxygen from water, but they are also experts at filtering out nitrogen and other particles so they don’t enter our body and have lasting effects on our health.
All these factors combined makes creating a recreation of gills incredibly difficult.
Could humans breathe underwater if we had gills?
No, humans cannot breathe underwater if we had gills. This is because while gills allow aquatic animals to extract oxygen from the water, the amount of oxygen in the water is much lower than the amount of oxygen in the air.
Additionally, while aquatic animals can extract oxygen from the water using their gills and move it into their bloodstream, human bodies are not equipped to move oxygen from water to our bloodstream.
Furthermore, our lungs cannot process the water the way gills do, so we would not be able to extract any oxygen from the water even if we did have gills. Therefore, humans would not be able to breathe underwater even if we had gills.
