Randomized trial examines body size and sexual dimorphism in colugos, suggesting distinct evolutionary paths.

This research aims to explore the variations in body size and the patterns of sexual dimorphism in two colugo genera.
Analyzed craniodental datasets from the Sunda Colugo and Philippine Colugo.
Identified morphological and dental traits to assess sexual dimorphism.
Female-biased size dimorphism observed in Galeopterus crania; females are larger in gross skeletal traits.
Cranial dimorphism is reduced or absent in Cynocephalus, while dental dimorphism favors males with more tines on incisors.
Findings indicate independent evolutionary paths for the extant colugo genera over approximately 11-20 million years.

McBride et al. (2026) studied this question.
