Examples: As the ensuing visits between the two groups made clear, in order to exist in the unmitigated harshness of the forest, the small Lykov tribe had to be increasingly adaptable and resilient to adversity, while attempting to balance adherence to a religious philosophy that would be a contributing factor in their demise. However, we do know that because they actively resist contact with the modern world and demonstrate aggressive behavior towards any attempt at foreign contact, they should remain undisturbed as any outside interference will jeopardize their unique culture.

The lost people of Teotihuacán likely created one of the most desired cities in ancient America featuring culture, art, diversity, and remarkable architecture; nevertheless, it is likely that the level of internal strife caused by and social disparity resulted in the people’s downfall. The aboriginal Australian Pintupi are becoming disconnected from their nomadic culture and traditions as a result of contact with Western civilization, which has brought modernization, making aspects of their culture (such as Dreaming) less relevant and leading to their “extinction”.
