In this article, 66 individuals from 17 localities of Tarsius syrichta across the southern Philippines were sampled using mitochondrial 12S ribosomal RNA (12S), Cytochrome B (CytB), and NADH Dehydrogenase Subunit 2 (ND2) gene fragments, nine nuclear microsatellites and genomic data extracted from tissues to empirically infer the geographic partitioning of the genetic variation within the Philippine tarsier. This was done with the aim of attempting to identify evolutionary distinct lineages that could then be applied for primate conservation. The results showed that their exists three principal evolutionary lineages, (1) Bohol-Samar-Leyte, (2) Dinagat-Caraga, and (3) Mindanao with eastern and western subclades of the Philippine tarsier that do not correspond to the current recognized subspecies. The authors argue until a comprehensive study of molecular, morphological and bioacoustics can occur, while existing evidence does not provide a basis for distinguishable taxonomic alternatives, it should at least provide enough evidence to partition the tarsier archipelago population into at least three genetic variants.
