“…Truly new primate species, much less genera, are exceedingly rare and often, like the kipunji and Arunachal macaque (Sinha et al, 2005;Chakraborty et al, 2007), are Red Listed as soon as they are described Kumar et al, 2008). Ethologists, morphologists, and molecular phylogeneticists must race poachers and habitat destruction to characterize and understand newly discovered primates while they still exist in their natural environments.…”

“…Additionally, the kipunji cranium offers no evidence of hybrid ancestry. But there is no reason to expect classic hybrid traits (e.g., supernumerary teeth; Ackermann et al, 2006) in a lineage that has had thousands of generations to weed out conflicts between its parental genomes, as witnessed by the fact that the kipunji and other such suspected hybrid taxa have been identified solely on the basis of their DNA (Tosi et al, 2000;Sinha et al, 2005;Chakraborty et al, 2007;Karanth, 2008;Karanth et al, 2008;Osterholz et al, 2008;Burrell et al, 2009;Zinner et al, 2009). …”

“…Several cercopithecid species are thought to have arisen through intrageneric introgression (Tosi et al, 2000;Chakraborty et al, 2007;Osterholz et al, 2008), and intergeneric hybridization has been reported in both captivity and (less frequently) the wild (Markarian et al, 1972;Chiarelli, 1973;Dunbar and Dunbar, 1974;Jolly et al, 1997). Like the kipunji, the golden and capped leaf monkeys (Trachypithecus geei and T. pileatus) of South Asia are proposed to have arisen through intergeneric hybridization between Semnopithecus and Trachypithecus (Karanth, 2008;Karanth et al, 2008;Osterholz et al, 2008).…”

Rungwecebus kipunji is a recently discovered, critically endangered primate endemic to southern Tanzania. Although phenetically similar to mangabeys, molecular analyses suggest it is more closely related to Papio or possibly descended from an ancient population of baboon-mangabey hybrids. At present, only a single kipunji specimen, an M1-stage juvenile male, is available for study; thus, the cranial morphology of the adult kipunji is unknown. In this study, we used developmental simulation to estimate the adult kipunji's 3D cranial morphology. We examined variation in cercopithecine developmental vectors, applied selected vectors to the juvenile cranium, and compared the resulting simulated adults to actual adult male papionins. Differences between papionin developmental vectors were small and statistically insignificant. This uniformity suggests conservation of an ancestral papionin developmental program. Simulated kipunji adults were likewise extremely similar. As a group, the simulated adults were morphometrically distinct from other papionins, corroborating the kipunji's generic status. Simulated adults were phenetically most similar to Lophocebus aterrimus but were distinguished from all adult papionins by the same unique traits that characterize the kipunji juvenile: a tall neurocranium, broad face, short nasal bones, concave anteorbital profile, and dorsally rotated palate. This concordance between juvenile and estimated-adult morphologies confirms that papionin cranial shape is largely established before M1 eruption. The estimated kipunji adult's neurocranium strongly resembles that of Papio, providing the first cranial evidence supporting their phylogenetic relationship. If the kipunji does indeed have a hybrid origin, then its phenetic affinity to L. aterrimus favors Lophocebus as the proto-kipunji's paternal lineage. Anat Rec, 293:388-401, 2010.

“…They then branched into several phyletic lineages that have been identified from morphological and molecular evidence. [6][7][8][9][10][11] We distinguish three main lineages of extant macaques, corresponding to three dispersal waves in Asia. The silenus lineage has the most disjunct geographical distribution, indicating an early dispersal.…”

The macaque radiation is as old as the hominin radiation, approximately 7 million years. After Homo, Macaca has the widest geographical range among primates, and both of these genera are present in tropical and temperate regions as well. Whereas the single extant representative of the genus Homo diverged through processes of cultural diversification, extant species of macaques emerged through processes of evolutionary diversification. Macaque societies are characterized by profound unity and great diversity, and can best be described as variations on the same theme. To understand macaque variation and adaptation, we must take into account the processes that insure the persistence of their societies across generations and environments.

“…But molecular date estimates, where available, are sometimes much older. Recent estimates include 2.4-2.6 Myr ago for Macaca nemestrina-Macaca pagensis (Ziegler et al 2007), 0.8-1.4 Myr ago for Presbytis femoralis-Presbytis natunae (Meijaard & Groves 2004), and 1 Myr ago for Macaca radiata-Macaca sinica (Chakraborty et al 2007; see also Tosi et al 2003;Chu et al 2007;Ting 2008). Even given possible acceleration of the molecular clock on islands ( Woolfit & Bromham 2005), these all suggest splits substantially older than 12 000 years-and this has implications for other splits involving the same islands.…”

The island rule states that after island colonization, larger animals tend to evolve reduced body sizes and smaller animals increased sizes. Recently, there has been disagreement about how often, if ever, this rule applies in nature, and much of this disagreement stems from differences in the statistical tests employed. This study shows, how different tests of the island rule assume different null hypotheses, and that these rely on quite different biological assumptions. Analysis and simulation are then used to quantify the biases in the tests. Many widely used tests are shown to yield false support for the island rule when island and mainland evolution are indistinguishable, and so a Monte Carlo permutation test is introduced that avoids this problem. It is further shown that tests based on independent contrasts lack power to detect the island rule under certain conditions. Finally, a complete reanalysis is presented of recent data from primates. When head-body length is used as the measure of body size, reports of the island rule are shown to stem from methodological artefacts. But when skull length or body mass are used, all tests agree that the island rule does hold in primates.
