Step-by-step explanation:
Anthropology is the study of humanity across time and space. It is a unique discipline that encompasses four interrelated subfields: physical anthropology, archaeology, linguistic anthropology, and cultural anthropology.
In physical anthropology, scientists study human biology and evolution to understand the emergence of culture. Archaeologists use artifacts to learn about ancient societies and their technologies. Linguistic anthropologists explore how language shapes culture, while cultural anthropologists study contemporary societies and the various aspects of their cultures.
By combining knowledge from these different fields, anthropologists gain a deeper understanding of humanity's central challenges, such as racial injustice and climate change.
