most isolated uncontacted tribes world
Isolated tribes or Uncontacted tribes are groups of indigenous people who have sustained life and community away from their contemporary societies and the rest of the world. While a more moderate term to describe them is indigenous peoples in voluntary isolation.
Some of the isolated tribes have been spotted and some have never even been contacted much mostly due to threat from lack of communication and the data and records that are available are mostly from neighboring indigenous communities or aerial data. Even the data and stats on the population is estimated and is a challenging task.
Contacting and even accidentally tackling an indigenous tribe community has been not so successful in the past with many researchers, explorers have been killed with the infliction of new and novel diseases affecting the tribes, resulting in endangerment to both the parties in contact.
