Phylogenetic relationships of gibbons (4 genera, 12 species) deduced from short/partial mitochondrial DNA sequences were with low resolution and inconsistent. Their divergence over the short period of time may require longer sequences for the higher resolution. To solve the problems, we newly sequenced the whole mitochondrial genome of Hylobates agilis, Hylobates pileatus, Nomascus sp. and Symphalangus syndactylus. A highly resolved phylogenetic tree was obtained for the mitochondrial genome in the neighbor-joining, maximum-parsimony and maximum-likelihood analyses. The divergence dates of mitochondrial genome were estimated by Bayesian method; Nomascus and the other two genera to 8.0 million years ago (MYA), Symphalangus and Hylobates to 7.0 MYA, Hylobates pileatus and the other two Hylobates species to 3.9 MYA and Hylobates lar and Hylobates agilis to 3.3 MYA. Our results support the generic rank of Nomascus, Symphalangus and Hylobates, and proposed a new scenario that the Hylobates gibbons diverged in the Pliocene. This study shows the potential of the whole mitochondrial genome analyses to reveal detailed divergence history of gibbons.

D004272 DNA, Mitochondrial Double-stranded DNA of MITOCHONDRIA. In eukaryotes, the mitochondrial GENOME is circular and codes for ribosomal RNAs, transfer RNAs, and about 10 proteins. Mitochondrial DNA,mtDNA
D006922 Hylobates A genus of the family HYLOBATIDAE consisting of nine species. The members of this genus inhabit rain forests in southeast Asia. They are arboreal and differ from other anthropoids in the great length of their arms and very slender bodies and limbs. Their major means of locomotion is by swinging from branch to branch by their arms. Hylobates means dweller in the trees. Gibbons,Gibbon
D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA. Animal,Metazoa,Animalia
D001499 Bayes Theorem A theorem in probability theory named for Thomas Bayes (1702-1761). In epidemiology, it is used to obtain the probability of disease in a group of people with some characteristic on the basis of the overall rate of that disease and of the likelihood of that characteristic in healthy and diseased individuals. The most familiar application is in clinical decision analysis where it is used for estimating the probability of a particular diagnosis given the appearance of some symptoms or test result.

D016013 Likelihood Functions Functions constructed from a statistical model and a set of observed data which give the probability of that data for various values of the unknown model parameters. Those parameter values that maximize the probability are the maximum likelihood estimates of the parameters.

D016415 Sequence Alignment The arrangement of two or more amino acid or base sequences from an organism or organisms in such a way as to align areas of the sequences sharing common properties. The degree of relatedness or homology between the sequences is predicted computationally or statistically based on weights assigned to the elements aligned between the sequences. This in turn can serve as a potential indicator of the genetic relatedness between the organisms.
