The Humanzee (also known as the Chuman, or Manpanzee) is a hypothetical chimpanzee/human hybrid. Chimpanzee (often shortened to chimp) is the common name for the two extant Species of Apes in the Genus Pan. Human beings, humans or man (Origin 1590–1600 L homō man OL hemō the earthly one (see Humus In Biology, hybrid has two meanings The first meaning is the result of interbreeding between two animals or plants of different taxa. Chimpanzees and humans are very closely related (95% of their DNA sequence, and 99% of coding DNA sequences are in common[1]), leading to contested speculation that a hybrid is possible, though no specimen has ever been confirmed. A DNA sequence or genetic sequence is a succession of letters representing the Primary structure of a real or hypothetical DNA Molecule

Etymology

In spite of the usual convention of portmanteau words to describe hybrids, there is no consensus as to which word to use, though "chuman" or "humanzee" are used in popular speech. Geneticists adhere to the portmanteau word convention to indicate which species is the sire. The father is defined as the Male Parent of an offspring The Adjective "paternal" refers to father parallel to "maternal" for (cf. tigon/liger) This is important because of the phenomenon of genomic imprinting where genes are expressed differently depending on which parent contributed them. A tigon or tigron is a hybrid cross between a male Tiger and a female Lion. The liger, is a hybrid cross between a male Lion and a female Tiger (i Genomic imprinting is a genetic phenomenon by which certain Genes are expressed in a Parent -of-origin-specific manner Hybrids are named according to the convention first part of sire's name + second part of dam's name (except where the result is unwieldy). "Mom" "Mum" and "Mommy" redirect here For geneticists, "Chuman" therefore refers to a hybrid of male chimpanzee and female human, while "Humanzee" or "manpanzee" refers to a hybrid of male human and female chimpanzee.

Feasibility

Humans have one chromosome fewer than other apes, since the ape chromosomes 2p and 2q have fused into a large chromosome (which contains remnants of the centromere and telomeres of the ancestral 2p and 2q) in humans. A centromere is a region of DNA typically found near the middle of a Chromosome where two Sister chromatids come in contact A telomere is a region of repetitive DNA at the end of Chromosomes which protects the end of the chromosome from destruction [2] Having different numbers of chromosomes is not an absolute barrier to hybridization. A chromosome is an organized structure of DNA and Protein that is found in cells. Similar mismatches are relatively common in existing species, a phenomenon known as chromosomal polymorphism. Polymorphism is a general concept in biology referring to a more than one version of a trait being actively present in a population

The genetic structure of all the great apes, and humans, is similar. Chromosomes 6, 13, 19, 21, 22, and X are structurally the same in all great apes. 3, 11, 14, 15, 18, and 20 match between gorillas, chimpanzees, and humans. Chimps and humans match on 1, 2p, 2q, 5, 7 - 10, 12, 16, and Y as well. Some older references will include Y as a match between gorillas, chimps, and humans, but chimpanzees (including bonobos) and humans have recently been found to share a large transposition from chromosome 1 to Y that is not found in other apes. [3]

This level of chromosomal similarity is roughly equivalent to that found in equines. The horse ( Equus caballus) is a hoofed ( Ungulate) Mammal, one of eight living species of the family Equidae. Interfertility of horses and donkeys is common, although sterility of the offspring (mules) is nearly universal. In its common modern meaning a mule is the offspring of a male Donkey and a female Horse, which is classified as a kind of F1 hybrid. Similar complexities and prevalent sterility pertain to horse-zebra hybrids, or zorses, whose chromosomal disparity is very wide, with horses typically having 32 chromosomes and zebras possessing between 44 and 62 depending upon species. A zorse or zebrula is the offspring of a Zebra stallion and a Horse mare; the rarer reverse pairing is sometimes called a In a direct parallel to the chimp-human case, the Przewalski horse (Equus przewalskii) with 33 chromosome pairs, and the domestic horse (E. Przewalski's Horse ( Equus ferus przewalskii, Equus przewalskii or Equus caballus przewalskii classification is debated ʃɨˈvælskiː or /zɨˈvɑːlskiː/ caballus) with 32 chromosome pairs, have been found to be interfertile, and produce semi-fertile offspring, where male hybrids can breed with female domestic horses. [4]).

In the 1920s the Soviet biologist Ilya Ivanovich Ivanov carried out a series of experiments to create a human/ape hybrid. The Union of Soviet Socialist Republics (USSR was a constitutionally Socialist state that existed in Eurasia from 1922 to 1991 Foundations of modern biology There are five unifying principles Ilya Ivanovich Ivanov (Илья Иванович Иванов - March 20 1932 ? was a Russian and Soviet Biologist who specialized At first working with human sperm and chimpanzee females, none of his attempts created a pregnancy. In 1929 he organized a set of experiments involving ape sperm and human volunteers, but was delayed by the death of his last orangutan. The orangutans are two Species of great apes known for their intelligence long arms and reddish-brown hair The next year he fell under political criticism from the Soviet government and was sentenced to exile in the Kazakh SSR during the Great Purge; he died two years later (see below). The Kazakh Soviet Socialist Republic (Қазақ Кеңестік Социалистік Республикасы Qazaq Keñestik Socialistik Respublikasi; Казахская Great Purge (Большая чистка transliterated Bolshaya chistka) was a series of campaigns of Political repression and Persecution

As far back as 1977, researcher J. Michael Bedford[5] discovered that human sperm could penetrate the protective outer membranes of a gibbon egg. Gibbons are the small Apes in the family Hylobatidae. The family is divided into four genera based on their Diploid Chromosome Among the apes, the gibbon is the farthest from humans. Bedford's paper also stated that human spermatozoa would not even attach to the zona surface of sub-hominoid primate (baboon, rhesus monkey, squirrel monkey), concluding that although the specificity of human spermatozoa is not confined to man alone, it probably is restricted to the Hominoidea.

In 2006, research suggested that after the last common ancestor of humans and chimpanzees diverged into two distinct lineages, inter-lineage sex was still sufficiently common that it produced fertile hybrids for around 1. Genetic divergence is the process of one species diverging over time into more than one species 2 million years after the initial split. [6]

However, despite speculation, no case of a human-chimpanzee cross has ever been confirmed to exist in modern times.

The Ivanov experiments

The most controversial of Ilya Ivanovich Ivanov's studies was his attempt to create a human-ape hybrid. Ilya Ivanovich Ivanov (Илья Иванович Иванов - March 20 1932 ? was a Russian and Soviet Biologist who specialized As early as 1910 he had given a presentation to the World Congress of Zoologists in Graz in which he described the possibility of obtaining such a hybrid through artificial insemination.

He dispatched letters to the People's Commissar on Education and Science Anatoliy Vasilievich Lunacharsky and to other officials. Council of Ministers of the USSR (Совет Министров СССР tr Ivanov's proposal finally sparked the interest of Nikolai Petrovich Gorbunov, the head of the Department of Scientific Institutions. In September 1925 Gorbunov helped allocate US$10,000 to the Academy of Sciences for Ivanov's human-ape hybridization experiments in Africa.

In March 1926 Ivanov arrived at the Kindia facility, but stayed only a month without success. Year 1926 ( MCMXXVI) was a Common year starting on Friday (link will display the full calendar of the Gregorian calendar. The Kindia site, it turned out, had no sexually mature chimpanzees. Chimpanzee (often shortened to chimp) is the common name for the two extant Species of Apes in the Genus Pan. He returned to France where he arranged through correspondence with French Guinea's colonial governor to set up experiments at the botanical gardens in Conakry. Conakry or Konakry ( Malinké: Kɔnakiri) is the Capital and largest city of Guinea.

Ivanov reached Conakry in November 1926 accompanied by his son, also named Ilya, who would assist him in his experiments. Year 1926 ( MCMXXVI) was a Common year starting on Friday (link will display the full calendar of the Gregorian calendar. Ivanov supervised the capture of adult chimpanzees in the interior of the colony, which were brought to Conakry and kept in cages in the botanical gardens. On February 28, 1927, Ivanov artificially inseminated two female chimpanzees with human sperm (not his own or his son's).

They already knew before leaving that the first two chimpanzees had failed to become pregnant. The third died in France, and was also found not to have been pregnant. The remaining chimps were sent to a new primate station at Sukhumi. Sukhumi, also spelled as Sukhum ( Abkhaz: Аҟəа Aqwa; სოხუმი Sokhumi, Сухуми/Сухум is the capital

Although Ivanov attempted to organize the insemination of human females with chimpanzee sperm in Guinea, these plans met with resistance from the French colonial government and there is no evidence such an experiment was arranged there.

Upon his return to the Soviet Union in 1927, Ivanov began an effort to organize hybridization experiments at Sukhumi using ape sperm and human females. Year 1927 ( MCMXXVII) was a Common year starting on Saturday (link will display full calendar of the Gregorian calendar.

In the spring of 1929 the Society set up a commission to plan Ivanov's experiments at Sukhumi. They decided that at least five volunteer women would be needed for the project. However, in June 1929, before any inseminations had taken place, Ivanov learned that the only postpubescent male ape remaining at Sukhumi (an orangutan) had died. The orangutans are two Species of great apes known for their intelligence long arms and reddish-brown hair A new set of chimps would not arrive at Sukhumi until the summer of 1930.

Rumored humanzees

There have been occasional reports and rumors of humanzees throughout history. St. Peter Damian, in his 11th century De bono religiosi status et variorum animatium tropologia, tells of a Count Gulielmus whose pet ape became his wife's lover. Saint Peter Damian, OSB ( Petrus Damiani, also Pietro Damiani or Pier Damiani; c One day the ape became "mad with jealousy" on seeing the count lying with his wife and it fatally attacked him. Damian claims he was told about this incident by Pope Alexander II and shown a creature named "Maimo", which was supposed to be the offspring of the countess and the ape. Alexander II (died April 21, 1073) born Anselmo da Baggio, was Pope from 1061 to 1073 It has been mentioned that Maimo was most likely a human child with an intellectual disability.

During World War II, infamous Nazi doctor Josef Mengele would sometimes torment uncooperative female Jewish prisoners in the Auschwitz concentration camp by showing them photos of chimpanzees and telling them he had impregnated them with the sperm from those chimps. World War II, or the Second World War, (often abbreviated WWII) was a global military conflict which involved a majority of the world's nations, including Nazism, which was a short name for National Socialism (Nationalsozialismus refers primarily to the Ideology and practices of the National Socialist German Dr Josef Mengele ( March 16, 1911 – February 7, 1979) was a German SS officer and a Physician in the PLEASE TAKE NOTE************ "Auschwitz" redirects here For the town see Oświęcim Auschwitz-Birkenau () was the largest of Nazi Germany Internment is the imprisonment or confinement of people commonly in large groups without trial A photograph (often shortened to photo) is an Image created by Light falling on a light-sensitive surface usually Photographic film or an electronic The term sperm is derived from the Greek word (σπέρμα sperma (meaning "seed" and refers to the male reproductive cells.

Oliver

There have been no scientifically verified specimens of a human/ape hybrid, although a performing chimp named Oliver was popularized during the 1970s as a possible Chuman/Humanzee. Oliver is a Common Chimpanzee and a former performing ape once promoted as a missing link or " Humanzee " due Oliver is a Common Chimpanzee and a former performing ape once promoted as a missing link or " Humanzee " due Genetic tests conducted at the University of Chicago concluded that, despite Oliver's somewhat unusual appearance and behavior, he was a normal chimpanzee;[8] he had the same number of chromosomes as normal chimpanzees.

The "hybrid" claims were possibly a promotional gimmick. As a result of being humanized (habituated to humans rather than to chimps), Oliver was said to be attracted to female humans, and did not mate with chimpanzees.

Genetic evidence

Looking back millions of years into early human history, current research into human evolution tends to confirm that in some cases, interspecies sexual activity may have been a key part of human evolution. Human evolution, or anthropogenesis, is the part of biological Evolution concerning the emergence of Homo sapiens as a distinct Species Animal sexual behaviour takes many different forms even within the same Species. Human evolution, or anthropogenesis, is the part of biological Evolution concerning the emergence of Homo sapiens as a distinct Species Analysis of the species' genes in 2006 provides evidence that after humans had started to diverge from chimps, interspecies mating between "proto-human" and "proto-chimps" nonetheless occurred regularly enough to change certain genes in the new gene pool:

"A new comparison of the human and chimp genomes suggests that after the two lineages separated, they may have begun interbreeding. History See also History of genetics The existence of genes was first suggested by Gregor Mendel (1822-1884 who in the 1860s studied inheritance Human beings, humans or man (Origin 1590–1600 L homō man OL hemō the earthly one (see Humus Chimpanzee (often shortened to chimp) is the common name for the two extant Species of Apes in the Genus Pan. In Population genetics, a gene pool is the complete set of unique Alleles in a Species or Population. Chimpanzee (often shortened to chimp) is the common name for the two extant Species of Apes in the Genus Pan. In classical genetics the genome of a Diploid Organism including Eukarya refers to a full set of chromosomes or genes in a Gamete, thereby . . A principal finding is that the X chromosomes of humans and chimps appear to have diverged about 1. The X chromosome is one of the two sex-determining Chromosomes in many animal species including mammals (the other is the Y chromosome) Genetic divergence is the process of one species diverging over time into more than one species 2 million years more recently than the other chromosomes. "

The research suggests that:

"There were in fact two splits between the human and chimp lineages, with the first being followed by interbreeding between the two populations and then a second split. The suggestion of a hybridization has startled paleoanthropologists, who nonetheless are 'treating the new genetic data seriously. Paleoanthropology, which combines the disciplines of Paleontology and Physical anthropology, is the study of ancient humans as found in Fossil hominid '[1]

Popular culture

Ape-like beings that have distinctly human traits are not uncommon in fiction, most notably in the Planet of the Apes series, but examples of actual human-ape hybrids in films are not as common. Planet of the Apes is a novel by Pierre Boulle, originally published in 1963 in French as La Planète des singes.
