In sillico Analysis of Mitochondrial DNA and Phylogenetic Relationships Among Genus Presbytis ( Presbytis comata, Presbytis fredericae, Presbytis mitrata, and Presbytis melalophos)

Type: article
Abstract: This study investigates the phylogenetic relationships among four species of Presbytis—Presbytis comata, Presbytis fredericae, Presbytis mitrata, and Presbytis melalophos—based on the mitochondrial cytochrome b gene sequences. These species, collectively known as leaf monkeys, share similar morphological features, which complicates species identification based solely on physical traits. To address this challenge, an in silico approach was employed, utilizing mitochondrial DNA sequences retrieved from the NCBI GenBank database. The sequences were analyzed using BLAST to ensure accuracy in alignment, followed by phylogenetic tree construction with MEGA software. The phylogenetic analysis revealed clear genetic distinctions between the species, despite their morphological similarities, with each species forming distinct clusters on the phylogenetic tree. The results demonstrate the utility of mitochondrial markers like cytochrome b in resolving evolutionary relationships in closely related species. These findings provide valuable insights into the genetic diversity and evolutionary history of Presbytis species, contributing to a better understanding of their taxonomy and evolutionary divergence. Furthermore, the study underscores the importance of genetic analysis in primate conservation efforts, as the genetic distinctions observed may inform targeted conservation strategies. This research highlights the critical role of molecular tools in understanding biodiversity and evolution, especially for species that are difficult to differentiate morphologically.
