Anthropology examines human adaptation, variation, and change. From a holistic perspective anthropologists study human adaptability in the past, present, and future by analyzing culture, society, language, and biology.
There are five main sub-disciplines in anthropology. Cultural anthropologists conduct participant-observation fieldwork in communities throughout the world. Archeologists investigate material cultural remains to better understand human behavior. Linguistic anthropologists examine how speech and language is used to communicate ideas about our environment and how language and speech changes over time and across geographical areas. Biological anthropologists research questions pertaining to human evolution, forensics, genetics, human growth and development, and demographics. Applied anthropology is conducted in all of these four sub-fields.
