In this new paper, we examined published diets of 112 primate species and found that out of the 205 plant families consumed, only 10 were eaten by more than half of the primate species. Plants of Moraceae (fruit) and Fabaceae (leaves) were the most widely and frequently consumed, with over 75% of primate species having fed on these two families. Together they made up approximately 13% of primate diets. Our results suggest that these two plant families are uniquely important to primates worldwide. Read the abstract here.
