The key step to understanding prehistoric evidence is dating, and reliable dating techniques have developed steadily since the nineteenth century. The most common of these dating techniques is radiocarbon dating. Further evidence has come from the reconstruction of ancient spoken languages. More recent techniques include forensic chemical analysis to reveal the use and provenance of materials, and genetic analysis of bones to determine kinship and physical characteristics of prehistoric peoples.
