Answer:
b. According to Marcus and Fischer (1986), "The cultures of world peoples need to be constantly rediscovered as these people reinvent them in changing historical circumstances.
Step-by-step explanation:
Anthropology represents the scientific study both of the past and present of societies and human behavior specifically to understand and identify patterns.
Since, the global economy and communication links continues to link all contemporary people, they continue to change as they are constantly influenced by what they are exposed to daily. Unlike previous times when a person's patterns and evolution were typically decided by his immediate environment, now globalization brings human influences from across the globe.
The anthropologist in his study therefore, must understand the complexities of diverse cultures and systems and how they come to play in constantly shifting the cultures of the people and constantly creating new behavioural patterns. This becomes an on-going discussion.
