Form and genes often tell different stories about the evolution of animals, with molecular data generally considered to be more objective than morphological data. However, form provides basis for description organisms, study fossils crucially depends on morphology. Complex organisms tend evolve as 'mosaics', in which parts may modified at varying rates response selective pressures. Thus, individual anatomical regions contain phylogenetic signals. In present study, we used computerized...
Abstract Aim To examine and visualize clines in size shape of Cercopithecus aethiops Linneus, 1758 (Primate, Cercopithecidae) skulls, to investigate environmental factors which might best explain the observed variation. Location Sub‐Saharan Africa. Methods Eighty‐six three‐dimensional anatomical landmarks were used describe 306 skulls adult C. sampled over its entire distribution. Geometric morphometric methods for quantitative analysis form variation applied. Size variables computed...
Baboons, members of the genus Papio, comprise six closely related species distributed throughout sub-Saharan Africa and southwest Arabia. The exhibit more ecological flexibility a wider range social systems than many other primates. This article summarizes our current knowledge natural history baboons highlights directions for future research. We suggest that can serve as valuable model complex evolutionary processes, such speciation hybridization. evolution has been heavily shaped by...
Hominin‐cercopithecid comparisons have been used in palaeoanthropology for over forty years. Fossil cercopithecids can be as a ‘control group’ to contextualize the adaptations and evolutionary trends of hominins. Observations made on modern also applied questions about human evolution. This article reviews history hominin‐cercopithecid comparisons, assesses strengths weaknesses comparators studies evolution, uses cercopithecid models explore hominin inter‐specific dynamics. Cercopithecids...
ABSTRACT Aim To provide accurate but parsimonious quantitative descriptions of clines in cranial form red colobus, to partition morphological variance into geographical, taxonomic and structured components, visually summarize multivariate shape data using a method which produces results directly comparable both univariate studies geographical variation standard geometric morphometric visualization differences along vectors. Location Equatorial Africa. Methods Sixty‐four three‐dimensional...
Aim To quantify how mammal community structure relates to heterogeneity of vegetation for palaeoecological reconstructions, and test whether historical or environmental factors are more important in structuring communities. Location Sixty-three natural protected areas Asia, Africa South Central America. Methods We defined faunal communities by allocating species ecological guilds calculating proportional representation within each guild. Vegetation area was calculated from satellite images....
Abstract Bone morphology of the cats (Mammalia: Felidae) is influenced by many factors, including locomotor mode, body size, hunting methods, prey size and phylogeny. Here, we investigate shape proximal distal humeral epiphyses in extant species felids, based on two‐dimensional landmark configurations. Geometric morphometric techniques were used to describe differences context phylogeny, allometry locomotion. The influence these factors epiphyseal was assessed using Principal Component...
Subspecific variation is widespread in vertebrates. Within Africa, several mammals have extensive geographic distributions with attendant morphological, ecological, and behavioural variations, which are often used to demarcate subspecies. In the present study, we use a primate species, vervet monkey, Cercopithecus aethiops, as case study for intraspecific divergence mammals, assessed through hard tissue morphology. We examine differences size, shape, non-allometric shape from taxonomic...
Abstract Nearly all primates are ecologically dependent on trees, but they nonetheless found in an enormous range of habitats, from highly xeric environments to dense rainforest. Most have a relatively ‘generalised’ skeleton, enabling locomotor flexibility and facilitating other crucial functions, such as manual foraging grooming. This paper explores the associations between habitat, locomotion morphology forelimbs cercopithecids (Old World monkeys), contextualising their skeletal...
The one modern member of the genus Theropithecus, T. gelada (Primates, Cercopithecidae), inhabits grassland and is highly terrestrial. It often supposed that Theropithecus oswaldi, most common primates Plio-Pleistocene East southern Africa, was also a terrestrial open habitat species. Ecomorphic analysis used to assess locomotor strategy preference it found this species unlikely have had identical gelada, with oswaldi possibly using arboreal substrates in manner similar some baboon groups....
Modern Old World monkeys live in an array of habitats, ability that was established early their evolutionary history. The monkey radiation is commonly correlated with the general trend climatic cooling Neogene and associated increase open habitats. However, although they became more abundant speciated extensively very late Miocene, Pliocene Pleistocene, many major events cercopithecoid evolution occurred before onset Miocene long period. In Plio-Pleistocene, regional environmental change...
