The teeth and skulls of the South African australopiths suggest that they had a vegetarian diet.
Indicate whether the statement is true or false.
Question 2
Scientists continue to debate the relationship between two Homo fossil finds: KNM-ER 1470, named H. rudolfensis by some, and KNM-ER 1813, generally considered to be an exemplar of H. habilis. Is the smaller KNM-ER 1813 a distinct species? Could it be a female version of KNM-ER 1470, both being simply a female and male pair of the highly variable H. habilis? The only sure conclusion is that
A. females are poorly represented in the hominin fossil record.
B. there is a trend in hominin evolution toward large molars.
C. no hominin fossil younger than 2.5 m.y.a. has exhibited chimplike features.
D. KNM-ER 1470 is more like an australopith than a Homo.
E. several different kinds of hominin lived in Africa before and after the advent of Homo.
The deer mouse and the African elephant represent extremes among mammals of r versus K selection.

The cranium of early African H. erectus KNM-ER 3733 is nearly 1.8 million years old.
