It was an amazing and exciting event for the body. A man with a fearsome headdress named hydra who appeared before the Heracles — the son of the Greek god Zeus.
But Heracles had a specific plan. Earlier he realized that hydra would have another head injury when he was cut off – so he decided to seek help from his nephew Lolaus.
It is clear that they discovered these unusual effects from their bodies. When Heracles attacked the animals, his nephew Lolaus appeared and cut off their necks and prevented the animal’s heads from growing again.
Hydra blood was claimed to be very dangerous
All the while the Beast Hydra uttered a loud and moving voice as his blood and the air he grew up giving threatened to destroy the Greek hero.
But Heracles managed to cut off the animal’s head.
Hydra is an animal that was known to have over 50 heads but many pictures showed him having fewer heads than claimed.
But where did the idea of one animal having more than one head come from?
Did the Greeks have the idea of a beast with many heads? Scientists have shown unusual cases of two-headed animals for many years.
And recently a conservative biologist Arkhat Abhzanov at the Imperial College in London, has seen many examples of two-headed animals in his laboratory and identified potential mutations.
It is true that over time the two- and three-headed animals are found in forests or in parks.
Interestingly, this phenomenon known as polycephaly is not limited to animals of the same species. For example, fish.
In 2013 the fetus of a two-headed pope was found in the Gulf of Mexico.
The following year, another similar case was discovered in marine mammals after a two-headed dolphin was found on the beaches of Turkey.
Both specimens appear to be attached to each other — due to the completely indistinguishable egg. The surface is made up of genes.
The list of animal models is very long including tortoises, snakes and even cats.
This is not the result these days as scientists have discovered the remains of two-headed embryos from a million years ago.
As Abzhanov explains there are a number of factors that cause an animal to have more than one head or more than one face.
Invertebrates or non-vertebrates all benefit from having many heads but come from different generations.
This is why organs such as eyes, ears, nose and mouth are found there. The surface formation is based on the animal’s own genes. And one gene has a profound effect especially on surface width.
They are invertebrates with the SHH gene.
Azbhanov argues that when the parasite continues to be weakened then its head becomes thinner and sometimes fails to grow and causes the animals to be born with one eye and a small head.
The cell that is known to cause the defect in sheep is known as “cyclopamine”.
It is found in corn oil for example and is widely consumed by pregnant women. When you take a group of those cells and place them in a frog’s embryo he will have two heads.
When you add SHH genes and become more numerous, the surface becomes wider until two heads appear.
“Such cases are not uncommon but are reported among domestic and wild animals,” said Abzhanov.
Naturally, a two-faced animal emerges and not two heads. In animals with two different necks growing from the same body, Abzhanov discovered another problem that occurs early in embryo growth.
The head is like any other organ of the body and grows from a single cell group, as soon as the embryo is present.
When you take one group of cells and place them in the frog’s embryo, the frog will have two heads.
It is clear that this group of cells produces signals that tell the animal to give a head.
This is what happens in the case of the twins who have been caught but Abzhanov has found that this is happening in the laboratory.
Azbhanov claims that one reason is the temperature. He and his companions took fertilized eggs from a chicken farm.
The embryos are then examined in a laboratory. But in the heat of the moment the team of researchers was able to identify an unusual problem.
“When the temperature reaches 30 degrees Celsius, the eggs have the same degree of defects, including a two-headed embryo,” he said.

Surprisingly, the problem has arisen elsewhere, one of the biologists for example noted that high temperatures in water cause the growth of a two-headed embryo.
It is unknown at this time what he will do after leaving the post, but more research is being done to determine the influence of heat on animals.
