Answer
Hominines can walk upright, have opposable thumbs, and big brains. An example of a hominine is the modern human ($Homo$ $sapiens$).
Work Step by Step
The ability to walk upright is the result of special placement of the skull, vertebral column, hip and leg bones as well as the change in the shape of the pelvis. Opposable thumbs allow hominines to grasp objects and use tools. The large brain results from a large increase in the size of the cerebrum.
