The systematics of the gorilla are reviewed in the light of abundant new material, examined with the aid of techniques of multivariate analysis. Defects are pointed out in the usually accepted view that there are two clear-cut subspecies (G. g. gorilla and G. g. beringei); the existence of morphological intergradation is shown, and an intermediate subspecies, G. g. grueri, is recognized in addition.read more

Assessment of the Diversity of African Primates
Peter Grubb,Thomas M. Butynski,John F. Oates,Simon K. Bearder,Todd R. Disotell,Colin P. Groves,Thomas T. Struhsaker +6 more
TL;DR: This account of the systematics of African primates is the consensus view of a group of authors who attended the Workshop of the IUCN/SSC Primate Specialist Group held at Orlando, Florida, in February 2000.

Biometric analysis of geographic variation and racial affinities
TL;DR: Using phenotypic variation to measure the similarity between the populations of a species one should analyse the variation in several characters simultaneously simultaneously, known as multivariate analysis.

A new approach to estimate parameters of speciation models with application to apes
Celine Becquet,Molly Przeworski +1 more
TL;DR: A new Markov chain Monte Carlo method is developed to estimate parameters of an isolation-migration model that suggests that the two chimpanzee species became reproductively isolated in allopatry while Western and Central chimpanzee populations split approximately 440 Kya but continued to exchange migrants.
Journal ArticleDOI
Great ape DNA sequences reveal a reduced diversity and an expansion in humans.
TL;DR: It is shown that humans differ from the great apes in having a low level of genetic variation and a signal of population expansion.

Foraging profiles of sympatric lowland gorillas and chimpanzees in the Lopé Reserve, Gabon.
Caroline E. G. Tutin,Michel Fernandez,M. Elizabeth Rogers,Elizabeth A. Williamson,William C. McGrew +4 more
TL;DR: The authors compare the diets of gorillas and chimpanzees and find that gorillas eat more vegetative plant parts than do chimpanzees, but niche separation is most obvious in periods of fruit scarcity when the two species show different strategies that reduce competition for food.

The descriptive use of discriminant functions in physical anthropology.
TL;DR: It was found that in the measurements examined, Pithecanthropus pekinensis resembled the Australian aboriginal more closely than any ape, whereas their molars and remaining premolars were in these features more ape-like than human.

Ecology and Taxonomy of the Gorilla
Colin P. Groves,Colin P. Groves +1 more
TL;DR: Multivariate analysis shows that the ecological diversity of the gorilla is reflected in the morphology of the skull and is of assistance in subspecific taxonomy.
