Review this chapter and answer the following questions: What are the parts of the skeleton that seem to be more commonly found as fossils? What are the anatomical clues that these fossils provide to help scientists address questions about hominin origins?

Accepted Answer

The answer of Review this chapter and answer the following...

Question 12

C)  a trait inherited from a common ancestor 
D)  a set of selective forces enacted on one lineage 
E)  a way to define an organism's repertoire of social behaviors

Question 18

Primatology helps anthropologists make inferences about the early social organization of hominids and untangle issues of human nature and the origins of culture. Of particular relevance to these types of questions are two kinds of primates:

Accepted Answer

A)  those with whom we share the least number of homologies, and those with whom we share the most analogies. 
B)  those that are in the tribe hominini, and those in the family hominidae. 
C)  those whose ecological adaptations are similar to our own (terrestrial monkeys and apes), and those most closely related to us, the great apes (chimpanzees and gorillas). 
D)  catarrhines and platyrrhines. 
E)  Gigantopithecus and Pierolapithecus.

Question 19

Behavioral ecology studies the evolutionary basis of social behavior. What is one of the discipline's main assumptions?

Accepted Answer

A)  Phenotype is the overwhelming result of genotype.

D)  There is no distinction between individual and inclusive fitness. 
E)  Individual fitness among hominins is measured differently than in other nonhuman primate species.
