This chapter sums up the key findings of this study on the treeshrews of Borneo. It explains that the small number of living tupaiid species and the fossil record suggests that the treeshrews' characteristics never provided much potential for evolutionary diversification, but that they can be considered an evolutionary success because they have been able to hold their own amid more populous orders. The chapter argues that the while the absentee maternal-nursing system works, it provides little flexibility in litter size or maternal behavior, and would not seem likely to offer much potential for evolving into other strategies needed for treeshrews to succeed in very cold climates or in places where survival of young was much lower.
