I want to know the answer to the following question:
How are long dead human groups presumed to have lived and behaved as compared to still living populations?
All the background I'm provided with is that "Ethnoarchaeology is a type of archaeology that studies the practices and material remains of living human groups in order to gain a better understanding of the evidence left behind by past human groups, who are presumed to have lived in similar ways.". Is that enough to answer the question?
Answer: yes
