| molecular phylogeny of treeshrews (mammalia: scandentia) and the timescale of diversification in southeast asia. | resolving the phylogeny of treeshrews (order scandentia) has historically proven difficult, in large part because of access to specimens and samples from critical taxa. we used "antique" dna methods with non-destructive sampling of museum specimens to complete taxon sampling for the 20 currently recognized treeshrew species and to estimate their phylogeny and divergence times. most divergence among extant species is estimated to have taken place within the past 20 million years, with deeper dive ... | 2011 | 21565274 |
