|Species:||Pan troglodytes or Pan paniscus x Gorilla gorilla or Gorilla beringei|
The Koolakamba or Kooloo-Kamba is a purported hybrid species of chimpanzees and gorillas. This alleged hybrid ape species has been reported in Africa as early as the mid 19th century though no empirical evidence has been found to substantiate the existence of the creature and it has no entry in the NCBI taxonomical database. The Koolakamba was referenced in the mid-19th century in French work by Franquet (1852, as cited by Shea, 1984) and in some descriptive work of Paul Du Chaillu from 1860, 1861, 1867, and 1899; some of which was republished in 1969 (Explorations and Adventures in Equatorial Africa).
Origins of the name
DuChaillu refers to the ape as Koolakamba based upon his description of words used by the indigenous peoples (Commi, Goumbi, and Bakalai[sic]) in the region of the Ovengi River of West Central Africa, modernly the areas of Cameroon and Gabon. The people allegedly referred to the ape as "Kooloo" because that is what its unique vocalization, quite unlike the vocalizations of other apes in the region, sounded like to them. "Kamba", according to DuChaillu, is a Commi word meaning to "speak" (DuChaillu, 1899).
Description and distinguishing features
The Koolakamba is believed to be larger, flatter faced, larger skulled and more bipedal than a chimp; though, it may also be a mutation. According to DuChaillu (DuChaillu 1861 and 1869), the physical characteristics described for Koolakamba include a short and broad pelvic structure, large supraorbital ridge, high zygomatic ridges, less prominent "muzzle", dentition in which the upper and lower incisors meet squarely forming a grinding surface, and a larger cranial capacity than that of the common chimpanzee. Much of what DuChaillu records is essentially ethnographic. He includes the indigenous names and lore relevant to the ape, and reveals his own cultural foibles in the writing. His works are classic period pieces with wonderfully descriptive text and presumably accurate illustrations, but limited quantitative (mostly anthropometric) data.
Although there has not been a documented sighting of the Koolakamba or a proof of its existence in modern days, in 1881 Koppenfelds indicated that it does exist indeed: “I believe it is proved that there are crosses between the male Troglodytes gorilla and the female Troglodytes niger, but for reasons easily understood, there are none in the opposite direction. I have in my possession positive proof of this. This settles all the questions about the gorilla, chimpanzee, Kooloo Kamba,....etc.” In November 1996, a picture of an unusual ape (taken by Peter Jenkins and Liza Gadsby at the Yaounde Zoo, Cameroon) was featured in the Newsletter of the Internal Primate Protection League (IPPL). This picture showed a seemingly hybrid ape with wider face and a larger skull than that of a chimpanzee and smaller than that of a gorilla. The ape in the picture had features that seemed to belong to both the gorilla and the chimpanzee.
Scientifically, the Koolakamba has not been determined to be a subspecies of the chimpanzee, a gorilla-chimpanzee hybrid, or perhaps even a representative of an individual variation. Yerkes reported several "unclassifiable apes" with features intermediate between chimpanzee and gorilla in his 1929 book "A Study of Anthropoid Life". In fact most of these are regional races of chimpanzee classified as separate species by over-enthusiastic naturalists.
