I hope you don’t ape the way I monkey around.

With language like that, it’s no wonder we have trouble remembering the differences between two suborder groups of primates. Do you know your monkeys from your apes?

God designed both monkeys and apes for life in trees. You can see that in the ways they are alike:

• Forward-facing eyes for good depth perception so they can judge distance between trees

• Flexible arms and legs for moving about and balancing

• Hands that can grasp branches

• Omnivorous—eat fruits, plants, insects, and small creatures
