Exam 3: African Roots

Bipedal primates considered to be in the human family or evolutionary line are called:

Orrorin is thought to have been bipedal based on the morphology of its:

Australopithecus africanus dates to how long ago:

The oldest evidence for bipedal primates dates to the period:

Compared to the australopithecines, the Homo habilis brain was:

By the end of the Miocene, the habitat of east Africa can be best described as a:

The "First Family" and Lucy are possible early representatives of what fossil genus:

Australopithecus africanus is now seen as representing:

The Miocene Epoch is dated to:

The key paleoanthropological discovery made at the site of Laetoli, in Tanzania, was of:

In the view of Pat Shipman, bipedalism is advantageous because it:

Were the earliest hominins primarily hunters or scavengers?

Describe the Lomekwi stone tools. How old are they? Who made them?

Most grasses follow which photosynthetic pathway:

The Laetoli footprints provide direct evidence for bipedalism in our ancestors at least how long ago:

The single most important consideration for placing a 4 million-year-old fossil in the hominin family is:

What major habitat change accompanies the end of the Miocene:

The fossil designated A. L. 444-2 shows that Australopithecus afarensis possessed:

How were Oldowan tools produced? Walk me through the steps for producing the tools. What were Oldowan flake tools used for? How do we know?

Oldowan was a well-planned, not a merely expedient technology. What does this mean and how do we know this? What does this imply about our hominin ancestors?
