Conclusions/Significance
Darwinius masillae represents the most complete fossil primate ever found, including both skeleton, soft body outline and contents of the digestive tract. Study of all these features allows a fairly complete reconstruction of life history, locomotion, and diet. Any future study of Eocene-Oligocene primates should benefit from information preserved in the Darwinius holotype. Of particular importance to phylogenetic studies, the absence of a toilet claw and a toothcomb demonstrates that Darwinius masillae is not simply a fossil lemur, but part of a larger group of primates, Adapoidea, representative of the early haplorhine diversification.

Eocene primates
The first primates of modern aspect appeared at the beginning of the Eocene epoch, about 55 m.y. before present. Two superfamilies can be recognized from the beginning: (1) Tarsioidea, including Eocene Omomyidae and Microchoeridae and living Tarsius; and (2) Adapoidea, including Eocene Notharctidae and Adapidae, with later representatives but no living primates. Tarsioidea are generally smaller, with estimated body weights less than 500 g; Adapoidea are generally larger, with estimated body weights greater than 500 g [2]–[4]. Within Notharctidae, the subfamily Cercamoniinae (sometimes considered a family Cercamoniidae) has special interest because of its shortened, robust dentaries, reduced antemolar dentition, and interlocking canines with monkey-like honing premolars [5], all features that may foreshadow anthropoids. Cercamoniinae include primates as widely dispersed as Protoadapis and Cercamonius from France, Europolemur from Germany, Caenopithecus from Switzerland, Mahgarita from Texas, and Aframonius from Egypt.
