A human–animal hybrid and animal–human hybrid is an organism that incorporates elements from both and non-human . Technically, in a human–animal hybrid, each cell has both human and non-human genetic material. It is in contrast to an individual where some cells are human and some are derived from a different organism, called a human-animal chimera. (A human chimera, on the other hand, consists only of human cells, from different zygotes.)
Examples of human–animal hybrids mainly include Humanized mouse that have been genetically modified by xenotransplantation of human genes. Humanized mice are commonly used as small animal models in biological and medical research for human therapeutics.
Human–animal hybrids are the subject of legal, moral, and technological debate in the context of recent advances in genetic engineering.
Human–animal hybrids have existed throughout Culture for a long time (particularly in terms of mythology), being a part of storytelling across multiple , and have also been incorporated into , , , and other related mass media in recent decades.
The question of what line exists between a "human" being and a "non-human" being has been a difficult one for many researchers to answer. While animals having one percent or less of their cells originally coming from humans may clearly appear to be non-human, no consensus exists on how to categorise beings in a genetic middle ground that have an approximately even mix. "I don't think anyone knows in terms of crude percentages how to differentiate between humans and nonhumans," U.S. patent office official John Doll has stated. Critics of increased government restrictions include scientists such as Douglas Kniss, head of the Laboratory of Perinatal Research at Ohio State University, who has remarked that formal laws are not the best option since the "notion of animal-human hybrids is very complex." He has also argued that their creation is inherent "not the kind of thing we support" in his kind of research since scientists should "want to respect human life".
In contrast, socio-economic theorist Jeremy Rifkin has expressed opposition to research that creates beings crossing species boundaries, arguing that it interferes with the fundamental 'right to exist' possessed by each animal species. "One doesn't have to be religious or into animal rights to think this doesn't make sense," he has argued when expressing support for anti-chimera and anti-hybrid legislation. As well, William Cheshire, associate professor of neurology at the Mayo Clinic's Florida branch, has called the issue "unexplored biologic territory" and advocated for a "moral threshold of human neural development" to restrict the destroying a human embryo to obtain cell material and/or the creation of an organism that's partly human and partly animal." He has said, "We must be cautious not to violate the integrity of humanity or of animal life over which we have a stewardship responsibility".
In terms of Bioethics, restrictions on the creation of human–animal hybrids have proved a controversial matter in multiple countries. While the state of Arizona banned the practice altogether in 2010, a proposal on the subject that sparked some interest in the United States Senate from 2011 to 2012 ended up going nowhere. Although the two concepts are not strictly related, discussions of experimentation into blended human and animal creatures has paralleled the discussions around embryonic stem-cell research (the 'stem cell controversy'). The creation of genetically modified organisms for a multitude of purposes has taken place in the modern world for decades, examples being specifically designed foodstuffs made to have features such as higher crop yields through better disease resistance.
President George W. Bush brought up the topic in his 2006 State of the Union Address, in which he called for the prohibition of "human cloning in all its forms", "creating or implanting embryos for experiments", "creating human-animal hybrids", and also "buying, selling, or patenting human embryos". He argued, "A hopeful society has institutions of science and medicine that do not cut ethical corners and that recognize the matchless value of every life." He also stated that humanity "should never be discarded, devalued or put up for sale."
A 2005 appropriations bill passed by the U.S. Congress and signed into law by President Bush contained specific wording forbidding any patents on humans or human embryos. In terms of outright bans on hybrid research in the first place, a measure came up in the 110th Congress entitled the Human-Animal Hybrid Prohibition Act of 2008. Congressman Chris Smith (R, NJ-4) introduced it on April 24, 2008. The text of the proposed act stated that "human dignity and the integrity of the human species are compromised" if such hybrids exist and set up the punishment of imprisonment for up to ten years as well as a fine of over one million dollars. Though attracting support from many co-sponsors such as then Representatives Mary Fallin, Duncan Hunter, Joseph R. Pitts, and Rick Renzi among others, the Act failed to get through Congress.
A related proposal had come up in the U.S. Senate the prior year, the Human-Animal Hybrid Prohibition Act of 2007, and it also had failed. That effort was proposed by then-Senator Sam Brownback (R, Kansas) on November 15, 2007. Featuring the same language as the later measure in the House, its bipartisan group of cosponsors included then Senators Tom Coburn, Jim DeMint, and Mary Landrieu.
A localized measure designed to ban the creation of hybrid entities came up in the state of Arizona in 2010. The proposal was signed into law by then Governor Jan Brewer. Its sponsor stated that it was needed to clarify important "ethical boundaries" in research.
In various mythologies throughout history, many particularly famous hybrids have existed, including as a part of Egyptian and Indian spirituality. The entities have also been characters in fictional media such as in H. G. Wells' work The Island of Doctor Moreau, adapted into the popular 1932 film Island of Lost Souls. In legendary terms, the hybrids have played varying roles from that of trickster and/or villain to serving as divine heroes in very different contexts, depending on the given culture.
A prominent hybrid figure that's internationally known is the Greek mythology figure of Pan. A deity that rules over and symbolizes the untamed wild, he helps express the inherent beauty of the natural world as the Greeks saw things. He specifically received reverence by ancient , fishermen, shepherds, and other groups with a close connection to nature. Pan is a Satyr who possesses the hindquarters, legs, and horns of a goat while otherwise being essentially human in appearance; stories of his encounters with different gods, humans, and others have been a part of popular culture in several different cultures for many years. The human-animal hybrid has appeared in acclaimed works of art by figures such as Francis Bacon, also being mentioned in Poetry such as in John Fletcher's writings. Specifically, the human-animal hybrid has appeared in acclaimed works of art by figures such as Francis Bacon. Additional famous mythological hybrids include the Egyptian Psychopomp, named Anubis, and the fox-like Japanese beings that are called Kitsune.
In Chinese mythology, the figure of Zhu Bajie (p=Zhūbājiè
) undergoes a personal journey in which he gives up wickedness for virtue. After causing a disturbance in heaven from his licentious actions, he is exiled to Earth. By mistake, he enters the womb of a sow and ends up being born as a half-man/half-pig entity. With the head and ears of a pig coupled with a human body, his already animal-like sense of selfishness from his past life remains. Matricide as well as Fratricide, he makes his way to a mountain hideout, spending his days preying on unwary travelers unlucky enough to cross his path. However, the exhortations of the kind goddess Guanyin, journeying in China, persuade him to seek a nobler path, and his life's journey and the side of goodness proceeds on such that even he is ordained a priest by the goddess herself. Remarking on the character's role in the religious novel Journey to the West, where the being first appears, professor Victor H. Mair has commented that "pig-human hybrids represent descent and the grotesque, a capitulation to the basest appetites" rather than "self-improvement".
Several hybrid entities have long played a major role in Japanese media and in traditional beliefs within the country. For example, a warrior god known as Amida received worship as a part of Japanese mythology for many years; he possessed a generally humanoid appearance while having a canine-like head. However, the god's devotional popularity fell in about the middle of the 19th century. A Tanuki resembles a raccoon dog, but its shape-shifting talents allow it to turn into humans for the purposes of trickery, such as impersonating Buddhist . The fox-like creatures known as Kitsune also possess similar powers, and stories abound of them tricking human men into marriage by turning into seductive women.
Other examples include characters in ancient Anatolia and Mesopotamia. The latter region has had the tradition of a malevolent human-animal hybrid deity in Pazuzu, the demon featuring a humanoid shape yet having grotesque features such as sharp talons. The character picked up revived attention when an interpretation of it appeared in William Peter Blatty's 1971 novel The Exorcist and the Academy Award winning 1973 film adaption of the same name, with the demon possessing the body of an innocent young girl. The movie, regarded as one of the greatest horror films of all time, has a prologue in which co-protagonist Father Merrin (Max von Sydow) visits an archaeological dig in Iraq and ominously discovers an old statue of the monstrous being.
Other notable examples include:
Examples from other geographic areas include:
The anthropomorphic characters in the seminal works by English writer Beatrix Potter in particular live an ambiguous situation, having human dress yet displaying many instinctive animal traits. Writing on the popularity of Peter Rabbit, a later author commented that in "balancing humanized domesticity against wild rabbit foraging, Potter subverted parental authority and its built in hypocrisy" in Potter's child-centered books. Writer Lisa Fraustino has cited on the subject R.M. Lockley's tongue-in-cheek observation: "Rabbits are so human. Or is it the other way around— humans are so rabbit?"
Writer H. G. Wells created his famous work The Island of Doctor Moreau, featuring a mixture of horror and science fiction elements, to promote the anti-vivisection cause as a part of his long-time advocacy for animal rights. Wells' story describes a man stuck on an island ruled over by the titular Dr. Moreau, a morally depraved scientist who has created several human-animal hybrids referred to as 'Beast Folk' through vivisection and even by combining parts of other animals for some of the 'Beast Folk'. The story has been adapted into film several times, with varying success. The most acclaimed version is the 1932 black-and-white treatment called Island of Lost Souls. Wells himself wrote that "this story was the response of an imaginative mind to the reminder that humanity is but animal rough-hewn to a reasonable shape and in perpetual internal conflict between instinct and injunction," with the scandals surrounding Oscar Wilde being the impetus for the English writer's treatment of themes such as ethics and psychology. Challenging the Victorian era viewpoints of its time, the 1896 work presents a complex situation in which enhancing animals into hybrids involves both terrifying violence and pain as well as appears essentially futile, given the power of raw instinct. A pessimistic view towards the ability of human civilization to live by law-abiding, Morality for long thus follows.
The H. P. Lovecraft–inspired movie Dagon, released in 2001, additionally features grotesque hybrid beings.
Hero examples of human-animal anthropomorphic characters include the two protagonists of the 2002 movie The Cat Returns (Japanese title: 猫の恩返し), with the Animation featuring a young girl (named "Haru") being transformed against her will into a Felidae-human hybrid and fighting a villainous king of the cats with the help of a dashing male cat companion (known as the "Baron") at her side.
The science fiction film Splice, released 2009, shows scientists mixing together human and animal DNA in the hopes of advancing medical research at the pharmaceutical company that they work at. Calamitous results occur when the hybrid named Dren (portrayed by Delphine Chanéac) is born.
Marvel Comics has a race of human-animal hybrids called the New Men who were created by the High Evolutionary by evolving the animals into humanoid forms.
