Final answer:
The limb bones of Ardipithecus provide insights into the movement and behavior of early humans and apes after diverging from a common ancestor.
Step-by-step explanation:
The limb bones of Ardipithecus provide insights into the movement and behavior of early humans and apes after they diverged from a common ancestor. Ardipithecus, specifically Ardipithecus ramidus, lived about 4.4 million years ago and was bipedal on the ground and quadrupedal in trees. The forward position of the foramen magnum and the small size of its upper arm bones suggest that Ardipithecus was bipedal on the ground. Its bipedalism, along with other features like a reduced canine, smaller brain size, and opposable big toe, show a transition towards human-like characteristics
