Completely contradictory thoughts arise in your head when you start thinking about creating hybrids by crossing animal and human cells. For a long time scientists create hybrid embryos in their laboratories, all this is done with the aim of searching possible methods treatment wide range diseases. However, this kind of experimentation with nature can go too far. Will animal-human hybrids ever be created? What place will they take in this world? These kinds of questions directly relate to the topic of confrontation between science and ethics.
Hybrids in the animal world
Is it possible to create hybrids of animals and humans? Some may immediately have eerie images of people with a tiger's head, a fish's tail, a bird's beak, shaggy hair, and so on. Could scientists in their labs create genetic modifications as easily as in a video game? In the animal world there is an example interspecific hybrids is a mule, the result of the mating of a donkey and a horse. This is a completely healthy animal, which, however, has lost its ability to reproduce its own kind due to different quantities chromosomes in a donkey (62 chromosomes) and a horse (64 chromosomes).
By the way, mules are not the only example of interspecific crossing. Many related species can mate to produce sterile offspring. For example, lions and tigers (their cubs are called ligers), zebras and horses. The closest relative of humans can be called a primate, but the mere thought of creating hybrids of animals and humans, namely humans and monkeys, by combining genomes is almost impossible.
The immune system rejects foreign cells
For the most part, the human immune system functions in such a way that even the cells of another person are not always successfully accepted by the body, for example, during a transplant internal organs, not to mention inhuman, animal cell. Any foreign tissue will be immediately detected and a powerful immune response - rejection - will follow.
Exclusively for the benefit of humanity
Scientists involved in genetic research do not have the goal of creating monsters where a hybrid of a human and an animal is something scary and terrible. In addition, the public will never accept the idea of creating any mutants. They are not interested in working on this kind of thing, stem cell research and therapeutic cloning are carried out solely in the interests of humans, and are primarily aimed at combating many incurable diseases.
Not so simple
One can imagine that hybrids of animals and humans (see below for a photo reflecting the public’s ideas about them) are still possible, since DNA is universal for almost any living organism. For example, protein in horse cells is synthesized in exactly the same way as in humans. However, everything is not so simple: to try to make a hybrid, you have to go through great amount trial and error, the question is how many people need to be sacrificed to make, for example, a mermaid. This may take much longer than it might seem at first glance.
It is relatively trivial to add human genes into animals and plants, and a completely different matter - vice versa. But individual genes determine only a specific protein; they cannot magically turn the organism into something completely different, for example, a chimeric monster. Individual genes make up only a small part who we are and who a dog or a jellyfish is. The type of individual depends on a number of often similar genes, packaged in a complex set of functional units, which can be completely different in individual species organisms.
Human-animal hybrid: what is this creature called from a scientific point of view?
From a scientific point of view, this issue is considered outside of fictional and mythical contexts. IN real life The creation of creatures such as animal-human hybrids is the subject of legal, moral and technological debate in the context of recent advances in the field of Should it be done at all? Will this be a surrender to base human desires or self-improvement? This hybrid of human and animal is called a “para-human”. They also belong to cytoplasmic hybrids - cybrids.
Hybrids as examples of interspecies friendship
Interspecies friendships in the animal kingdom, and between humans and their pets, provide the basic root of the popularity of such creatures. Many famous hybrids have existed in various mythologies throughout history, including as part of Egyptian and Indian spirituality. According to one artist and scientist Pietro Gaetto, “ideas of human-animal hybrids always have their origins in religion.”
A human-animal hybrid is an entity that includes human and animal components. For thousands of years, these hybrids have been one of the most common themes in animal stories around the world. The absence of a strong divide between man and nature in several traditional and ancient cultures has provided a basic historical context for the popularity of fairy tales where humans and animals have mixed relationships that result in one becoming something entirely different.
Human-animal hybrid - fictional character or possible reality?
Currently, there remain, in essence, images of which are often used in video games and popular science fiction films and books. Invented hybrids play a variety of roles, from mutant villains to divine heroes. As for ancient beliefs and mythology, a huge number of hybrids can be found here, for example, Pan is a deity in Greek mythology, which symbolizes wild and untamed nature, was worshiped by hunters, fishermen and shepherds. cheerful character has hind limbs with hooves and goat horns, but otherwise its appearance is quite similar to that of a human. Another famous mythological hybrid is the Egyptian god of death named Anubis.
A deity named Chu Pa-Tze is expelled from heaven to Earth for his atrocities and dissolute actions. By mistake, he enters the sow's uterus and is eventually born half human, half pig, with a pig's head and ears combined with human body. The inner essence of this mythological hybrid does not change for the better.
After he kills and eats his mother and brothers, the pig-like monster takes refuge in the mountains, where he spends his days preying on unwary travelers unfortunate enough to cross his path. However, thanks to the efforts of the good goddess Guan Yin, traveling around China, he was persuaded to stand on a higher ground. noble path and be ordained a priest.
Experiments to create hybrid embryos
Is it possible to create a human-animal hybrid? A hybrid embryo is a mixture of human and animal tissues. There are several types of hybrid embryos, for example, cytoplasmic embryos are created by transferring nuclei containing DNA from human cells into an animal egg from which its own genetic information has been previously removed. The resulting embryos are grown in the laboratory for several days, then collected to create stem cells. The latter can become certain types of fabrics.
This method of creating stem cells is used for research various diseases and is considered a good alternative to human eggs themselves, which are available in more limited quantities, unlike animals. Scientists do not actually intend to create a human-animal hybrid, a creature capable of independent life.
Risks of mixing genetic material
The mixing of human and animal genetic material can lead to the risk of creating new diseases, but advances in this area can bring enormous benefits to humanity in a global sense. As scientists say, these are just cells, not real creatures. This avoids the use of human eggs in research. The animal's genetic contribution to the embryo is so small that it is essentially a human embryo (99.9%). Since the latter was not produced by human fertilization, it cannot be considered human.
Human and animal rights are not violated because the embryo will never be allowed to become human or animal. Biologists have been mixing the DNA of different animals since the 70s, but the idea of bringing animal genes into people remains taboo. And the violation of these prohibitions can, ultimately, not only save humanity from huge number diseases, but also radically change our entire species.
Transgenesis can involve both several individual cells and the entire organism. A human-animal hybrid (the name “chimera” was used in Greek mythology) is also referred to as a transgenic entity, which in the future can be used to model specific human diseases, produce new materials, tissues, and much more. About forty years ago, specialists learned to transport and modify the genes of plants and animals. The use of human material remains controversial, particularly for moral and ethical reasons.
We bring to your attention a selection of photographs dedicated to the strangest hybrid animals. Most of these animals are not found in nature in natural conditions and were bred by man. The fact of their appearance caused a lot of controversy and criticism. In most of these animals, with successful crossing, the offspring, as a rule, turn out to be infertile, therefore the appearance of new individuals is possible only with human intervention.
1. Zebra + any other horses = zebroid. Zebroids are the descendants of a zebra and any other horse: they are essentially hybrid zebras. Typically, male zebras and females of other equines are used to produce these hybrids. Zebroids usually have body contours more similar to their mother and have paternal stripes on the legs or parts of the neck and body. The female that produces a zebroid can be a female horse, pony, donkey or mule.
2.
3. Lion + tiger = liger.
4. Ligers are called hybrids obtained as a result of crossing between a male lion (Panthera Leo) and a female tigress ( Panthera Tigris). It is the largest known extant feline.
5. Ligers love and know how to swim, which is characteristic of tigers, and are very sociable, like lions. Ligers exist only in captivity, since the habitats of the parent species, the crossing of which leads to the birth of a liger, do not overlap in the wild. Another feature of ligers is that female ligers can give birth to offspring, which is unusual for feline hybrids. The length of a liger can reach four or more meters, and its weight exceeds three hundred kilograms.
6. Bottlenose dolphin + False killer whale = orca-dolphin
The orca dolphin is a rare hybrid that is born as a result of the mating of a female bottlenose dolphin with a male black killer whale (Pseudorca crassidens). Currently, only two specimens of killer whales live in marine park entertainment Sea Life Park in Hawaii.
The first hybrid was an orca dolphin named Kekaimalu. It was a female who turned out to be capable of having offspring. She gave birth to a baby in a very at a young age. The baby died a few days after birth. However, in 1991, Kekaimala gave birth again, and her daughter was given the name Pokaikealoha. For two years she cared for her cub. Pokaikealoha died at the age of nine.
7. Grizzly bear + polar polar bear = Polar grizzly or grolar.
8. The polar grizzly bear is a rare hybrid of a grizzly bear and a polar bear that is found both in captivity and in the wild. In 2006, the appearance of this hybrid in nature was confirmed by DNA research strange looking bear that was shot near Sachs Harbour, Northwest Territories on Banks Island in the Canadian Arctic.
9. Bison + American bison = bison.
Bison are hybrids of bison and American bison. The breed was created to combine the characteristics of both animals and to increase beef production. Bison produce fertile offspring both when crossed with each other and with representatives of the original species.
The creation of bison turned out to be a serious problem for preserving the wild population American bison. Most modern bison are genetically already bison, as they appeared as a result of crossing two species.
10. Serval + domestic cat = Savannah
Savannah is a breed of cat formed as a result of crossing domestic cat and the African serval. These are medium-sized animals, with big ears. Unusual view became popular among breeders in the late 20th century, and in 2001 the International Cat Association designated it as a newly registered breed. Savannahs are much more sociable than the average domestic cat and are often compared to dogs due to their loyalty to their owners. They can be trained to walk on a leash and even fetch objects thrown by their owner.
11. Bengal breeder Judy Frank crossed Susie Woods' male Serval with a Siamese domestic cat. This is how the first Savannah cat appeared. The first representative of the breed was born on April 7, 1986. One of Savannah's kittens was acquired in 1989 by Patrick Keighley. Keighley was one of the first enthusiasts who worked on the creation new breed, based on a cross between a serval and a domestic cat. Together with breeder Joyce Sroufe, Patri Keighley developed the first edition of the new breed standards.
12. Male donkey + female horse = mule.
A mule is the product of crossing a male donkey and a female horse. Horses and donkeys are animals different types, With different number chromosomes. Of the two F1 hybrids between these two species, a mule is easier to obtain from a cross than a hinny (the offspring of a cross between a horse and a donkey). All male mules and most female mules are sterile.
13. The main color of a mule is determined by the color of the mares. Based on their performance, there are two types of mules: pack and draft mules. Mules can be light, moderately heavy, or even, when a draft horse mare was used for crossing, moderately heavy.
14. The main color of a mule is determined by the color of the mares. Based on their performance, there are two types of mules: pack and draft mules. Mules can be light, moderately heavy, or even, when a draft horse mare was used for crossing, moderately heavy.
Passionate adherents of the species claim that mules are more patient, resilient, hardy and live longer than horses, and less stubborn, faster and smarter than donkeys. In addition, mules are less susceptible to diseases and do not require food and care.
15. Yak + cow = Dzo (khainak).
Zou is a hybrid of a yak and a cow. The word "Zo" technically refers to the males, while the females are called dzomo or zhom.
Dzomo can have offspring, but dzo are sterile. Because they are a product of the hybrid genetic phenomenon of heterosis, they are larger and stronger than a cow or yak. In Mongolia and Tibet, these animals are used for milk and meat.
16. Wolf + dog = wolf dog.
Wolf dogs are a breed formed by crossing a wild wolf and a dog. In 1998, according to the American Veterinary Medical Association and the United States Department of Agriculture, there were about 300 thousand wolfdogs living in the United States. A wolf is usually crossed with a dog of similar appearance (e.g. german shepherds, Siberian Huskies, Alaskan Malamute) for the appearance of the most attractive exotic pets for owners. However, we must take into account that since wolf-dogs are, in fact, a genetic cross between wolves and dogs, their physical and behavioral characteristics can be absolutely unpredictable.
August 4, 2016 National institutions US Health (NIH) announced that they were going to lift the moratorium on the creation of chimeras. It's about about ethically controversial experiments in which human stem cells are injected into animal embryos, resulting in the formation of organisms that combine animal and human traits. Scientists call them chimeras.
IN Ancient Greece Chimeras were mythological monsters with the head and neck of a lion, the body of a goat and the tail of a snake. The same chimeras are organisms with genetically heterogeneous material. They could serve as convenient biological models for studying various diseases - for example, cancer or neurodegenerative syndromes, and could become a source of organs for transplantation. However, it is worth experimental biology to come close to science fiction, there are public concerns that this could lead to unintended consequences.
When creating chimeras, stem cells that have the property of pluripotency are used. In other words, they are capable of turning into all the cells of a human embryo. The cells are introduced into the embryonic tissue of model organisms (mice, rats, monkeys, pigs and other animals) at very early stages, after which the embryo is allowed to develop further. In September 2015, the NIH expressed concern that if stem cells were injected into the brains of mice, the result could be rodents with altered cognitive abilities—that is, animals with “superintelligence.” Therefore, the NIH, which awards grants for biomedical research, has decided to withhold funding for experiments with chimeras until its experts examine the ethical issue.
However, some research groups in the USA they were already busy creating chimeras. MIT Technology Review reports that in 2015, there were about 20 attempts to produce pig-human and sheep-human chimeras. Unfortunately, not a single one scientific work has not yet been published, and there have been no reports of successful production of animals with human tissues.
Experiments with chimeric organisms combine both genetic engineering and stem cell biology. It is not enough to simply introduce pluripotent cells into an animal embryo, since in this case the result may be an organism with catastrophic developmental disorders. Scientists typically turn off genes in embryos so that they cannot form specific tissues. In this case, stem cells take on the task of forming the missing organ, which is no different from a human one, making it suitable for transplantation.
According to cardiologist Daniel Garry, the first tests were carried out in his laboratory this method. The researchers engineered pigs that lacked some skeletal muscle and blood vessels. Such animals would not be viable, but scientists added stem cells from another pig embryo to the embryos. The results so impressed the US military that they awarded Harry a $1.4 million grant to grow human hearts from pigs. The scientist intended to continue his research despite the NIH moratorium, and was one of 11 authors who published a letter criticizing the biomedical center's decision.
Scientists said the NIH moratorium poses a threat to the development of stem cell biology, developmental biology and regenerative medicine, and expressed doubts that using stem cells it is possible to obtain a “humanized” animal with high intelligence. In particular, they pointed out that xenotransplantation experiments in which nerve cells people are implanted into the brains of mice, did not lead to the emergence of overly smart rodents.

As a precaution, some researchers working on creating chimeras do not allow their creations to be born. Embryologists study embryos to gain information about how much human stem cells contribute to fetal development. However, despite the fact that some laboratories are playing it safe, chimeric animals already exist - for example, mice endowed with immune system person. Such animals are created through the introduction of liver and thymus cells from aborted human embryos into the body of already born rodents.
Of greatest interest to scientists is the creation of chimeras at the blastocyst stage, when the fetus is a ball consisting of several dozen cells. This method is called embryo complementation. In 2010, researchers from Japan managed to create mice whose pancreas consisted entirely of rat cells. Hiromitsu Nakauchi, the lead author of the paper, later decided to create a “pig-man,” for which he had to move to the United States because scientific committees in Japan do not approve of such experiments. The scientist is now working at Stanford University with a grant from the California Institute of Regenerative Medicine. Most of the pluripotent cells introduced into embryos in his lab are made from his own blood, he said, because bureaucratic barriers prevent him from recruiting outside volunteers.
Most people hear the word "chimera" and think of monsters created by mad scientists. Scientists have to prove that human cells can indeed multiply and form full-fledged and healthy organs in animals. Mice and rats are quite close genetically, so creating chimeras is not a problem in this case. In the case of humans and pigs, whose common ancestor lived 90 million years ago, things may be different.
Scientists are already testing the complementation of a pig embryo with human stem cells, but the research began only after the approval of three bioethics commissions. Stanford University, where the research is being conducted, limited the development time of the embryos to 28 days (piglets are born on day 114). However, the fetus will be sufficiently developed so that it can be determined how correctly the rudiments of the organs are formed.
Last week, the NIH proposed replacing the moratorium with additional review by a committee of ethicists and animal welfare experts. They will take into account factors such as the type of human cells, where they are located in the embryo, and possible changes in behavior and appearance animal. The experts' findings will help the NIH decide whether to fund the project under review.
Incredible facts
In the fictional world there are many strange and unusual creatures, and with using Photoshop You can create different non-existent animals.
All animals on this list are real.
These true hybrid animals are the result of genetic engineering, which could give rise to even more exotic creatures in the future.
Did you know about such animals as leopon, narluha or hainak?
Animal hybrids (photo)
1. Liger - a hybrid of a lion and a tigress
Ligers are the offspring of male lions and female tigresses. Although there are legends that ligers roam the wild, they currently only exist in captivity, where they are specially bred.
There is a misconception that ligers do not stop growing throughout their lives. That's not true, they just grow to huge size in its growth range. Ligers are the most big representatives felines in the world. Hercules is the most large liger weighs 418 kg.
2. Tigon - a hybrid of a tiger and a lioness
The tigon or tiger lion is a hybrid of a male tiger and a female lioness. Tigons were thought to be smaller than their parents, but in fact, they reach the same size, but they are smaller than ligers.
Both ligers and tigrolves are capable of producing their own offspring, which leads to the birth of such hybrids as titigons or liligers.
3. Zebroid - a hybrid of a zebra and a horse
A zebroid is a mixture of a zebra and other equines. Zebroids have been around for quite some time, they were mentioned in Darwin's notes. They are typically males with the physiology of a non-zebra parent and stripes adorning certain parts of the body.
Zebroids are more wild than domestic animals, are difficult to tame, and are more aggressive than horses.
4. Coywolf - a hybrid of a coyote and a wolf
Coyotes are genetically similar to red and eastern wolves, from which they diverged about 150,000 to 300,000 years ago. Interbreeding between them is not only possible, but is becoming more common as the wolf population recovers.
However, coyotes are not very compatible with gray wolves, from which they are genetically separated by 1-2 million years. Some hybrids, although they exist, are very rare.
There are different hybrids of coywolves that inhabit mainly North America. They are usually larger than coyotes, but fewer wolves, and have characteristics of both types.
5. Grolar - a hybrid of a polar and brown bear
Grolars, also called polar grizzlies, are a hybrid of a polar and brown bear. Most polar grizzlies live in zoos, but there have been a few sightings of them in the wild. In 2006, an Alaskan hunter shot and killed one.
Outwardly they look like both white and brown bears, but in behavior closer to polar bears.
6. Savannah - a hybrid of a domestic cat and a serval
It's amazing, but rare breed is a hybrid of domestic cats and a serval - a species wild cats living in Africa. They are very large and behave like dogs, following their owner around the house, wagging their tail to express pleasure, and even playing with a ball.
In addition, savannahs are not afraid of water and are easily adaptable. However, these cats are very expensive.
Interspecific animal hybrids
7. Orca-dolphin - a hybrid of an orca and a dolphin
A male black killer whale and a female bottlenose dolphin give rise to killer whales and dolphins. They are extremely rare and only one specimen is known to exist in captivity.
8. Cow bison - a hybrid of a cow and a bison
The cow-buffalo hybrid has been around since the 19th century, when they were called katalos. Cow bison are healthier than large ones cattle and apply less environmental damage prairies where they graze.
Unfortunately, as a result of breeding, there are now only 4 herds of bison that do not have cow genes.
9. Hinny - a hybrid of a stallion and a donkey
Essentially, a hinny is the opposite of a mule. A mule is the offspring of a donkey and a mare, and a hinny is a hybrid of a stallion and a donkey. Their head is similar to that of a horse and they are slightly smaller than mules. In addition, hinnies are less common than mules.
10. Narluha - a hybrid of a narwhal and a beluga whale
Narwhal and beluga whale are two members of the narwhal family, so it is not surprising that they are capable of interbreeding.
However, they are extremely rare. Lately they were more often seen in the eastern part Atlantic Ocean, which many consider a sign of climate change.
11. Kama - a hybrid of a camel and a llama
Kama did not exist until 1998. Some scientists at the camel reproductive center in Dubai decided to crossbreed a male dromedary camel with a female llama through artificial insemination, obtaining the first kama.
The purpose was to produce wool and use the kama as a beast of burden. To date, five camel-llama hybrids have been produced.
12. Khaynak or dzo - a hybrid of a cow and a yak
Dzo (male) and dzomo (female) are hybrids between domestic cows and wild yaks. They are mainly found in Tibet and Mongolia, where they are valued for their high yield of meat and milk. They are larger and stronger than both cows and yaks, and are often used as beasts of burden.
Hybrids of the animal world
13. Leopon - a hybrid of a leopard and a lioness
From a male leopard and a lioness comes the leopon. This situation is almost impossible in the wild, which is why all leopons were bred in captivity. Leopons have the head and mane of a lion, and the body of a leopard.
14. Sheep and goat hybrid
Goats and sheep seem very similar, but they are much more different from each other than they seem at first glance. Natural hybrids between these animals are usually stillborn and are extremely rare. The animal, called a goat-sheep chimera, was artificially grown from goat and sheep embryos.
15. Yaglev - a hybrid of a jaguar and a lioness
Yaglev is a hybrid of a male jaguar and a lioness. Two yagles, named Zhazhara and Tsunami, were born at Bear Creek Wildlife Sanctuary in Ontario.
16. Mulard - a hybrid of wild and musky duck
The Mulard is a cross between a wild duck and a Muscovy duck. The Muscovy duck lives in the South and Central America and is distinguished by bright red growths on the face. Mulards are raised for meat and foie gras, but they themselves cannot produce their own offspring.
17. Zubron - a hybrid of a cow and a bison
The bison is a hybrid of a cow and a bison. Zubrons are superior to domestic cows in many respects, as they are stronger and more resistant to disease.
They were considered as a possible replacement for cattle, but now bison remain in only one herd in Belovezhskaya Pushcha in Poland.
Brave naturalist researchers worked on both birds and pets, and even took up the inhabitants wildlife. Their creations are the fruit of bizarre passions of different types. What marvelous animals are on this list?
Famous hybrid birds
Back at the end of the 19th century, hunters who practiced the use of birds of prey began to think about breeding them in captivity. Shortly before World War II, the Master of the Order of German Falconers, Reinz Waller, received offspring from peregrine falcons, and his followers received artificially bred saker falcons. But what if there is not a pair for every creature? In the 1970s, Irish ornithologists Stevens and Morris crossed the peregrine falcon and saker falcon to create the first hybrid bird. Subsequent experiments brought even more interesting results.Perlin
The feathered creature, born from the union of a peregrine falcon and a merlin, is famous for its hunting abilities. This falcon, very popular among English aristocrats, helps in catching small birds on open spaces. Its main prey are partridges, larks and pigeons. The name “perlin” is derived from the addition of the first two syllables of the parent breeds: peregrine (peregrine falcon) and merlin (merlin).Eagle hybrid
The recent experiment of St. Petersburg falconer Sergei Shchegolkov was followed by ornithologists all over the planet. By crossing an imperial eagle and a golden eagle, he got an elegant bird of prey. The tail, as long as that of a golden eagle, helps to maneuver well, and its wide span guarantees high speed. The hybrid has been tested in winter hunting and is now used for catching hares.A cross between a bullfinch and a canary
In 1961, an article appeared in the German magazine Deutsche Gefliigel Zeitung describing a captive-bred canary chick and a female bullfinch. The lower half of the cub's body was rusty red, and the wings and tail were brown. Foreign experience I was able to repeat it only once. As scientist Boris Manteuffel has proven, crossing tropical birds and forest dwellers is not an easy matter.Banduk
From Arabic, the name of the small colorful bird, which appeared from the goldfinch and canary, is translated as “rogue.” Banduks can easily become a decoration for any home. From the bright canary they inherit a greenish back and yellow breast, and from the goldfinch - an orange mask around the beak. Unfortunately, it is not yet possible to obtain offspring from such hybrids. 
Breeding birds is a troublesome and thankless task. It is much more interesting to create new, unusual pets.
Pets obtained by crossing
By selecting two animals with similar genes, scientists try to produce offspring with better qualities than their parents. Most often, the crossing turns out to be fruitless, but sometimes very nice pets are born.Wolfdog
In 1998, a study by the American Veterinary Association showed that there are more than 300 thousand wolfdogs living in the United States. The combination of two related species is very productive. This is how Alaskan Malamutes and Siberian Huskies arose. Even German Shepherds have both wolves and dogs in their ancestry. The only disadvantage of such genetic intervention is the unpredictable behavioral and physical characteristics toothy baby. 
Khaynak
In appearance, livestock born from the inbreeding of a domestic cow and a yak looks like a bull with a ponytail. Its weight exceeds three centners, and the amount of milk the most milking cow in the village can envy. Khaynak is very popular in agriculture Mongolia, Tibet and Nepal. Males have good endurance and are used for transporting goods, and females produce 9 more calves in their lives than the usual heifer.Camelama
On January 14, 1998, the world learned about a new inhabitant of the Asian barnyard - the camel. Scientists have done their best by artificially inseminating animals that differ not only in size, but also in habitat. Villager Cub South America and Asia has a long camel-like tail and short ears. His strong legs can withstand the longest trip through the desert. 
Savannah
In 2001 the list International Association cats has been replenished with a new registered breed. Savannah, which appeared as a result of crossing the African serval and the common murka, is very loyal and affectionate. This animal, distinguished by its huge ears, can be led on a leash and even trained.But the most daring and craziest experiments were carried out on undomesticated fauna.
Wild animal hybrids
IN early XIX century, menagerie owners, dreaming of attracting the public, began work on creating strange creatures. In 1837 the first famous history The feline hybrid was introduced to Queen Victoria in India.Liger
The animals, born from a tiger mother and a lion father, are considered the largest cats in the world. The height of the Hercules liger, which lives in Miami, is about 3 meters. Although these animals rarely give birth, in 2004, two little liger cubs were born at the Novosibirsk Zoo. By the way, tigers, which are the result of crossing a lioness and a tiger, on the contrary, are distinguished by their miniature size. 
Peasley
In 2006, Jim Martell, hunting in the Canadian Arctic, shot and killed a wondrous beast. Identification of the corpse, carried out by a British Columbia laboratory, confirmed that this grizzly cub and polar bear came into being without human intervention. Hybrid cubs have been born before - for example, in the zoo in Halle, Germany back in 1874. 
killer bee
The experiment of crossing European bees with species from Africa is known for its disastrous results. 26 families born in the laboratory of the University of Rio Clara broke free and long years terrorized the entire area. 150 people and hundreds of animals became victims of bites. Even flamethrowers could not save us from monstrous hybrids.It is difficult to list all the creations created by an inquisitive mind and painstaking work. But both young and old know about this creature.
The most famous hybrid animal
A cross between a mare and a donkey, called a “mule,” was used back in the Middle Ages. 
Mules accompanied the conquistadors in the conquest of America and transported cannons during the Civil War. And now these pack cattle, which inherited speed from their mother and endurance from their father, are very popular on the farm. Although mules do not bear offspring, they can work for up to 40 years.
Many animals are surprising, not just species obtained by crossing. .
