Sundaland, tropical Southeast Asia,shosts 3 species of Rattus endemic to elevations above 2000 m with an apparent convergencesin external morphology: Rattus korinchi and R. hoogerwerfi from Sumatra, and R. baluensissfrom Borneo. A fourth one, R. tiomanicus, is restricted to lowland elevations across the wholesregion. The origins of these endemics are little known due to the absence of a robust phylogeneticsframework. We use complete mitochondrial genomes from the 3 high altitude Rattus, and severalsrelated species to determine their relationships, date divergences, reconstruct their history ofscolonization, and test for selection on the mitochondrial DNA. We show that mountain colonizationshappened independently in Borneo (<390 Kya) and Sumatra (~1.38 Mya), likely from lowlandslineages. The origin of the Bornean endemic R. baluensis is very recent and its genetic diversity issnested within the diversity of R. tiomanicus. We found weak evidence of positive selection in theshigh-elevation lineages and attributed the greater nonsynonymous mutations on these branchess(specially R. baluensis) to lesser purifying selection having acted on the terminal branches in thesphylogeny.} }
