What we don't know

Open questions are tracked here until evidence answers them. The Truism never fills a gap with an assumption.

  • What specific cultural, social, or medicinal role did betel nut use play in this ancient community?
  • What evidence establishes the teeth’s age and association with the residue?
  • How were the traces identified specifically as betel nut?
  • How were contamination and non-consumption explanations assessed?
  • What prior finding provides the comparison for the “earliest direct evidence” designation?
  • Has the underlying research been peer reviewed, and what limitations do its authors report?
