Final answer:
Forensic anthropologists testify in trials to present expert analysis of biological evidence from human remains, thereby aiding in solving crimes and providing information about the individuals involved.
Step-by-step explanation:
Forensic anthropologists are asked to testify at trials because they provide expert analyses of human remains, contributing valuable information to legal cases. Their expertise in biological anthropology enables them to answer the key questions in a crime, such as who died, how they died, when they died, and the distinctive features of the individuals involved. They apply rigorous scientific methods in the examination of recovered human skeletal remains, examining aspects like age, sex, race, and stature, and working alongside forensic pathologists who determine the cause of death. Furthermore, forensic anthropologists might examine historic cases, such as the Jamestown colony incident, where they help understand past human behavior and corroborate historical accounts. Their testimony can be vital in murder trials where biological evidence plays a central role.
