Morphological and behavioral adaptations for foraging in generalist primates: the case of the cebines.

abstract：:Periodic episodes of food scarcity may highlight the adaptive value of certain anatomical traits, particularly those that facilitate the acquisition and digestion of exigent fallback foods. To better understand the selective pressures that favored the distinctive dental and locomotor morphologies of gibbons and orangu...
