Abstract
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 humans inform about biological variation and evolutionary changes. The Lingual Cuspule has only been reported in one other world population, thus very little is known about this anomaly. It was thought that paraconids have been otherwise lost in primate evolution starting in the Oligocene (34-23 MYA). The expression of a paraconid in modern humans could suggest secondary evolution of this trait. Further reporting of both traits is necessary to discuss the implications of human dental evolution which result from the presence of these variants.
Highlights
Dental anomalies in modern humans are used to discuss biological variation and evolutionary changes
Ac- the lingual cuspule, which was observed on a single cessory cusps are initiated after the principal cusps individual (Irish, 1991)
In addition vidual presented in this paper was found at the Shick to the lingual cuspule and the paraconid, the individusite located in Mount Cory, Handcock County, Ohio al presented here exhibited a low-grade expression occupied between 2500-500 BC
Summary
2019 │ Volume 32 │ Issue 01 looked, in which case studies should highlight them, or third molar and the anterior cusp (paraconid) was exthat they are misinterpreted, which would indicate pressed bilaterally. Individuals in the Late Archaic sample exhibited a variety of other lower molar traits including low-grade ex-. This study was conducted on human skeletal remains cusp 6 (n=11), large cusp 7 (n=1), deep anterior fovea from the Archaic Period in the Ohio Valley. In addition vidual presented in this paper was found at the Shick to the lingual cuspule and the paraconid, the individusite located in Mount Cory, Handcock County, Ohio al presented here exhibited a low-grade expression occupied between 2500-500 BC. The upper ic period were considered “sizable” compared to earli- molars of this individual exhibit a reduction in size of er periods, and were occupied on a seasonal basis the hypocone from the first to third molars on both (Sciulli and Oberly 2002).
