Question

question 19 (2.5 points)
a feature that distinguishes new world and old world monkeys is _.
a tail
arm vs. leg length
bipedalism
a prehensile tail
a small brain

Explanation:

New World monkeys (Platyrrhini) have prehensile tails which can grasp objects, while Old World monkeys (Cercopithecidae) do not have prehensile tails. Both have tails (but different in functionality - prehensile vs non - prehensile). Arm vs leg length is not a key distinguishing feature. Bipedalism is more associated with some hominids rather than a key monkey distinction. Brain size is not the main differentiator here compared to the tail feature.

Answer:

a prehensile tail
