In 1978, Soviet geologists discovered the Lykov family living deep in the Siberian taiga wilderness, completely isolated from society for over 40 years after fleeing religious persecution in 1936 - the family of six had built a cabin and survived by farming, foraging and hunting, with no idea World War II had occurred or knowledge of modern society, amazing the geologists with their primitive existence; the Lykovs consisted of parents Karp and Akulina, sons Savin and Dmitry, and daughters Natalia and Agafia, who struggled to grow food in the harsh conditions while in constant fear of wolves and bears - after being discovered, some younger family briefly ventured out into Soviet society but later returned to the forest, with the last surviving member Agafia dying in 2021 at age 78.
