"In the past, treeshrews have commonly been considered basal members of the order Primates, or united with macroscelidids in the ""insectivoran"" clade Menotyphla. However, as a group they have no immediate living relatives and are best classified at ordinal rank (Butler, 1972, 1980; Dene et al., 1978; Luckett, 1980; McKenna and Bell, 1997). At a deeper phylogenetic level, scandentians apparently form a natural group with dermopterans and primates (Murphy et al., 2001b). Representatives of the order are confined to southern, eastern, and SE Asia both currently and in the fossil record, which extends back to the Middle Eocene in east Asia (McKenna and Bell, 1997). Most previous workers have arranged Scandentia as a monofamilial order, but recognition of two families (Tupaiidae and Ptilocercidae) more aptly conveys the anatomical disparity evident among the living treeshrews (see below).Despite the attention paid to the higher-level phylogenetic relationships of treeshrews,...
