Would it be possible for a human to have a tail?
Growing a true human tail is extremely rare. Sometimes, when babies are born, their parents might think they have a true tail when actually they don’t. This is called a pseudotail. Pseudotails are usually a symptom of an irregular coccyx or of spina bifida as opposed to a remnant of the embryonic tail from the womb.
Would humans be better with tails?
Squirrels and monkeys, though, use their tails to keep their balance and sometimes to even hold on to a branch. Humans walk really well on just two legs, so we don’t need tails to help us keep our balance. In fact, a tail might throw us off balance.
Has any human ever had a tail?
True human tails are rarely inherited, though familial cases have been reported. In one case the tail has been inherited through three generations of females. Human tails may be associated with other congenital anomalies in 29% of cases,9 commonest is spina bifida.
Why did humans lose their tails?
Recently, researchers uncovered a genetic clue about why humans have no tails. They identified a so-called jumping gene related to tail growth that may have leaped into a different location in the genome of a primate species millions of years ago. And in doing so, it created a mutation that took our tails away.
Is it possible for a human being to have a tail?
Human tails are a rare entity. The birth of a baby with a tail can cause tremendous psychological disturbance to the parents. They are usually classified as true and pseudo tails. [1] Tails are usually associated with occult spinal dysraphism.
How rare is it for a human to have a tail?
While tails are very rare in humans, temporary tail-like structures are found in the human embryo. These tails develop around the fifth or sixth week of gestation , and contain about 10 to 12 vertebrae.
What would happen if humans had a tail?
It would be similar to having a finger broken.Tails would be sexualized. Tail length and girth would become a major factor in how males were perceived and tail envy would be ubiquitous. There would be fierce, violent debate over whether it is proper for females to expose their tails in public.
Would humans benefit from a tail?
No, tails have no purpose in modern humans today.

Why do humans no longer need tails?
We don’t swing through the trees anymore and, on the ground, our bodies are aligned with a centre of gravity that passes down our spines to our feet without needing a tail to counterbalance the weight of our head. If we want to swat flies, we have our hands.
Why did humans once have tails?
For half a billion years or so, our ancestors sprouted tails. As fish, they used their tails to swim through the Cambrian seas. Much later, when they evolved into primates, their tails helped them stay balanced as they raced from branch to branch through Eocene jungles.
When did humans lose our tails?
25 million years ago
Were humans supposed to have tails?
Inside the uterus, human embryos start off with a tail that gradually disappears and once we come into this world, there’s a tailbone to remind us that we haven’t gone that far. Strikingly, our early ancestors lost their tails not once, but twice, say scientists who analyzed 350-million-year-old fossils.
Has a human ever had a tail?
True human tail is a rare event with fewer than 40 cases reported in the literature (figure 1). Here we present a case report of an infant born with a true tail. A 3-month-old baby girl was brought to paediatric surgery outpatient department, with the complaint of having an 11 cm long tail.
What if human beings had a tail?

What is the benefit of having a tail?
Many land animals use their tails to brush away flies and other biting insects. Some species, including cats and kangaroos, use their tails for balance; and some, such as monkeys and opossums, have what are known as prehensile tails, which are adapted to allow them to grasp tree branches.
Why did humans need a tail?
Our primate ancestors used their tails for balance as they navigated treetops, but around 25 million years ago, tailless apes started appearing in the fossil record.
Why do humans not need a tail?
Tail loss took place about 25 million years ago, long before our species, Homo sapiens, walked the Earth. Over the many millions of years that followed, the genetic playbook for tail development in our lineage ceased to function, and all the pieces that were required for tails to develop have long since been lost.
