Human–animal hybrid
The term human–animal hybrid or animal–human hybrid refers to an entity that incorporates elements from both humans and non-human animals. For thousands of years, these hybrids have been one of the most common themes in storytelling about animals throughout the world. The lack of a strong divide between humanity and animal nature in multiple traditional and ancient cultures has provided the underlying historical context for the popularity of tales where humans and animals have mingling relationships, such as in which one turns into the other or in which some mixed being goes through a journey. Interspecies friendships within the animal kingdom, as well as between humans and their pets, additionally provides an underlying root for the popularity of such beings.In various mythologies throughout history, many particularly famous hybrids have existed, including as a part of Egyptian and Indian spirituality. According to artist and scholar Pietro Gaietto, ""representations of human-animal hybrids always have their origins in religion"". As well, ""successive traditions they may change in meaning but they still remain within spiritual culture"" in his view. The entities have also been characters in fictional media more recently in history 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 play varying roles from that of trickster and/or villain to serving as divine heroes in very different contexts, depending on the given culture.For example, Pan is a deity in Greek mythology that rules over and symbolizes the untamed wild, being worshiped by hunters, fishermen, and shepherds in particular. The mischievous yet cheerful character has the hindquarters, legs, and horns of a goat while otherwise being essentially human in appearance, with stories of his encounters with different gods, humans, and others being retold for centuries on after the days of early Greece by groups such as the Delphian Society. 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 god of death, named Anubis, and the fox-like Japanese beings that are called Kitsune.When looked at scientifically, outside of a fictional and/or mythical context, the real-life creation of human-animal hybrids has served as a subject of legal, moral, and technological debate in the context of recent advances in genetic engineering. Defined by the magazine H+ as ""genetic alterations that are blendings [sic] of animal and human forms"", such hybrids may be referred by other names occasionally such as ""para-humans"". They may additionally may be called ""humanized animals"". Technically speaking, they are also related to ""cybrids"" (cytoplasmic hybrids), with ""cybrid"" cells featuring foreign human nuclei inside of them being a topic of interest. Possibly, a real-world human-animal hybrid may be an entity formed from either a human egg fertilized by a nonhuman sperm or a nonhuman egg fertilized by a human sperm. While at first being a concept in the likes of legends and thought experiments, the first stable human-animal chimeras (not hybrids but related) to actually exist were first created by Shanghai Second Medical University scientists in 2003, the result of having fused human cells with rabbit eggs. As well, a U.S. patent has notably been granted for a mouse chimera with a human immune system.In terms of scientific ethics, 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.Despite the legal and moral controversy over the possible real-life making of such beings, then President George W. Bush even speaking on the subject in his 2006 State of the Union, the concept of humanoid creatures with hybrid characteristics from animals, played in a dramatic and sensationalized fashion, has continued to be a popular element of fictional media in the digital age. Examples include Splice, a 2009 movie about experimental genetic research, and The Evil Within, a survival horror video game released in 2014 in which the protagonist fights grotesque hybrid creatures among other enemies.
