Answer:
there are three different species.
Step-by-step explanation:
There are three different species of monkey according to the hypothesis because all monkey species have different feeds i. e. one feed on the fruits while the other feed on the tree sap. It also shows that two monkey species have same feed i. e. eating fruits while one specie feeds on tree sap. This hypothesis also shows that no specie of monkey feeds on leaves and insects present on the trees.
