Case Study: Expression of Two Near Absent Dental Traits, Lingual Cuspule and Paraconid, on One Archaic Period Modern Human from the Ohio Valley

Case Study: Expression of Two Near Absent Dental Traits, Lingual Cuspule and Paraconid, on One Archaic Period Modern Human from the Ohio Valley

Presented here are the linugal cuspule and paraconid; two traits considered near absent (occurring <1%) in world populations. Both traits were found on lower third molars of one individual from late Archaic (2500-500BC) site of Shick in, Handcock County, Ohio. Rare dental anomalies in modern huma...
