By the numbers

  • 4,000-year-old skeletons studied.
  • 1 of 6 sampled individuals showed betel nut use.
  • Betel nut chewing dates back 9,000 years in Thailand.

The big picture

  • Betel nut use has deep cultural roots in Southeast Asia.

Caveats

  • Evidence based on one individual; limited sample size.
  • Unclear why only one individual showed betel nut use.
