Despite what we now know about race, anthropology still relies on the physical description of race. Forensic anthropology, which analyzes human remains with the intention of aiding criminal investigations still uses the descriptor of race to describe and match missing persons. The use of race still persists, because while we know that there is no real biological basis for race, there is a social basis for race, which must be acknowledged. We can use the genetic variation between populations of different geographical locations, known as ancestry, to determine possible race. This aids in finding missing persons and suspects, and matching missing persons to remains.
