List FOUR characteristics from the list above that are similar to that of Australopithecus africanus. State TWO advantages of having an opposable thumb. Explain why Professor Berger called Karabo a transitional fossil.

3.4.1)
The characteristics from the list similar to Australopithecus africanus are:

• Small brain
• Prognathous face
• Bipedal
• Smaller canines

3.4.2)
Two advantages of having an opposable thumb are:

• It allows for a precision grip, enabling the manipulation of small objects.
• It facilitates the making and using of tools.

3.4.3)
Professor Berger called Karabo (Australopithecus sediba) a transitional fossil because it exhibits a mosaic of features. It possesses characteristics found in both earlier Australopithecus species (e.g., small brain size, long arms) and later Homo species (e.g., human-like pelvis, smaller teeth), indicating an intermediate evolutionary stage between these groups.
