Anthropologists study the origins of human language, cultures, institutions, organisations, and other social and physical developments. Most anthropologists are specialised, and can normally be categorised into one of the following groups:
Biological anthropologists study the evolution of humans. They often spend their careers looking for past evidence of human life, and identify differences between current humans and our ancestors. Sometimes their work takes on forensic qualities, as they might try to identify reasons for a particular group's demise. Some biological anthropologists spend a lot of time working on legal proceedings. For example, they might analyse skeletal remains to help a jury understand how a person may have died.
Cultural anthropologists study the customs, cultures, and social rules of different groups. Some cultural anthropologists study cultures in large urban settings that are familiar to most of us, while others study remote cultures that we know little about. They normally use interviews and observational methods to learn more about their subjects. Depending on the location of the culture, extended travel may be required for people in this specialty.
Linguistic anthropologists study ways that humans communicate, and the impact that language has on our lives. Some linguistic anthropologists study spoken language, but most also study non-verbal cues (like body language), and identify ways that these signals change from culture to culture. Sometimes, it's necessary to study distant cultures to really understand the impact of language.
