Abstract

Abstract: Shennongjia Rhinopithecus roxellana (SNJ R. roxellana ) is the smallest geographical population of R . roxellana . The phylogenetic relationships among its genera and species and the biogeographic processes leading to their current distribution are largely unclear. To address these issues, we resequenced and obtained a new, complete mitochondrial genome of SNJ R. roxellana by next‐generation sequencing and standard Sanger sequencing. We analyzed the gene composition, constructed a phylogenetic tree, inferred the divergence ages based on complete mitochondrial genome sequences, and analyzed the genetic divergence of 13 functional mtDNA genes. The phylogenetic tree and divergence ages showed that R. avunculus (the Tonkin snub‐nosed monkey) was the first to diverge from the Rhinopithecus genus ca. 2.47 million years ago (Ma) . Rhinopithecus bieti and Rhinopithecus strykeri formed sister groups, and the second divergence from the Rhinopithecus genus occurred ca. 1.90 Ma. R. roxellana and R. brelichi diverged from the Rhinopithecus genus third, ca. 1.57 Ma. SNJ R. roxellana was the last to diverge within R. roxellana species in 0.08 Ma, and the most recent common ancestor of R. roxellana is 0.10 Ma. The analyses on gene composition showed SNJ R. roxellana was the newest geographic population of R. roxellana . The work will help to develop a more accurate protection policy for SNJ R. roxellana and facilitate further research on selection and adaptation of R. roxellana . Abstract : The analyses on phylogenetic tree and divergence time showed that SNJ Rhinopithecus roxellana had the least structure and the more recent divergence times of R. roxellana, which indicated more unfavorable environmental factors made SNJ R. roxellana into a newest rapid evolutionary geographic population of R. roxellana .
