Define "Archaeology" as a subdiscipline of anthropology, and name and describe its 3 sub-fields.

Archaeology is a subdiscipline of anthropology that studies human history and prehistory through the excavation of sites and the analysis of artifacts and other physical remains. It is a way to look back at the cultures and societies that came before us and understand how they lived, what they valued, and how they contributed to modern society.

The three sub-fields of archaeology are:

1. Prehistoric Archaeology: This field focuses on the time in human history before the existence of written records. Prehistoric archaeologists use tools like pottery, tools, and other artifacts to understand how early humans lived and evolved.

2. Historical Archaeology: This field focuses on civilizations that existed during the time of written records. It often involves the study of physical artifacts and structures left behind by people, as well as historical records and documents.

3. Classical Archaeology: This field focuses on the civilizations of the Classical period, such as Ancient Greece and Rome. Classical archaeologists study buildings, art, and everyday items to understand the cultures and societies of this time period.
