QUESTION 1

How are members of the genus Homo different physically
from the Australopithecus?

flattening of the face (the mouth doesn’t protrude forward like the australopithecines)

shorter arms

smaller-sized teeth and jaws

all of the above

none of the above (Homo and Australopithecus are basically the same in anatomy)  

1 points   

QUESTION 2

The
brain of Homo is:

smaller than the brain of Australopithecus

almost identical in size to the brain of Australopithecus

larger than the chimpanzee-sized brain of Australopithecus

adapted primarily for life in trees (arboreal adaptation)

QUESTION 3

The skeleton of Homo erectus:

is more apelike (more similar to a chimp or gorilla) than human

is adapted for walking differently than modern man (more like gorilla knuckle-walking)

is adapted for walking almost identically to the way modern humans walk

is radically different from modern humans

Homo habilis

Homo erectus

Neandertal

flattening of the face (the mouth doesn’t protrude forward like the australopithecines)

Explanation / Answer

Answer 1. The correct option is D. All of the above. The differences between australopithecines and early humans can be easily diffrentiated in the head. Humans developed significantly larger brains and relatively smaller faces which are less protuding with progressively smaller teeth and jaws. Also the arm length was considerably shorter.

Answer 2. The correct option is C. larger than the chimpanzee-sized brain of Australopithecus. As discussed in the answer 1, humans developed larger brain size.

Answer 3. The correct option is C. is adapted for walking almost identically to the way modern humans walk.

As the name erectus suggest, they walked straight and upright like modern humans do, and not like apes. Apes do knuckle walking while homo erectus was bipedal.

Answer 4. The correct option is A. Oldowan. The name comes from what has been termed the Oldowan Industry, named after the type of sites found in Olduvai Gorge, Tanzania, where these oldest known stone tools were discovered in large quantities.

Answer 5. The correct option is A. Australopithecus afarensis.
The oldest known stone tool was found to be dated back to 3.3 million years ago. It is the same time Australopithecus afarensis were present.
