The Ivanov experiments[edit]

Ilya Ivanovich Ivanov was the first person to attempt to create a human–ape hybrid.[8] As early as 1910 he gave a presentation to the World Congress of Zoologists in Graz, Austria, in which he described the possibility of creating such a hybrid by artificial insemination.[citation needed]

In the 1920s, Ivanov carried out a series of experiments to create a human/nonhuman ape hybrid. Working with human sperm and female chimpanzees, he failed to create a pregnancy.[9] In 1929 he organized a set of experiments involving nonhuman ape sperm and human volunteers, but was delayed by the death of his last orangutan.[9] The next year he fell under political criticism from the Soviet government and was sentenced to exile in the Kazakh SSR; he worked there at the Kazakh Veterinary-Zootechnical Institute and died of a stroke two years later.


There have been no scientifically verified specimens of a human/ape hybrid. A performing chimp named Oliver was popularized during the 1970s as a possible chuman/humanzee.[10] A geneticist from the University of Chicago examined Oliver's chromosomes in 1996 and revealed that Oliver had forty-eight, not forty-seven, chromosomes, thus disproving the earlier claim that he did not have a normal chromosome count for a chimpanzee.[11] Oliver's cranial morphology, ear shape, freckles and baldness fall within the range of variability exhibited by the Common Chimpanzee.[12] Scientists performed further studies with Oliver, the results of which were published in the American Journal of Physical Anthropology.[13]
