It is fascinating to think that even in this tech-saturated day and age there are places on this planet where tribes of people live with little or no contact with the outside world. Tonight we get the rare opportunity to peer into their world. Just weeks ago, seven members of a previously uncontacted amazonian tribe emerged in Brazil after threats from illegal loggers and drug traffickers forced them from their home in Peru. Several years ago a similar story prompted me to travel up the Amazon to a place no reporter had been before. I was standing up there before, they could have come up -- Yeah, you could have easily got with bitten there. How quickly will it kill you? He says very quickly. All right, great. Reporter: We came to meet the alananuae Indians. Who for millennia had zero contact with the outside world. While in recent years they'd had limited outside contact, they still essentially lived in the same ways as their ancestors in the stone age. The pace of life here couldn't be more different than ours. While they'd had a few modern tools like motor boats, swim trunks, and goggles, they seem to only take the parts of modernity that help them live their ancient lifestyle. In fact, they still live in large communal huts which led me to an imbetter net question. This is an insensitive question. If you want to be alone with your wife, you want to be intimate with your wife, living in a room filled with people, how do you have privacy? Reporter: They told me they get plenty of privacy at night when everybody's asleep. Apparently so. At the time of this interview, this guy had seven children and his wife was pregnant with number eight. A new national geographic series called "Survive the tribe" takes viewers inside remote cultures and asks the survivalist to live as the tribe lives for ten days. In the jungle survival skills are imperative. Knowing how to find water and emergency calories like these beetle larvae. I wouldn't say that insect grubs are my favorite. These people have evolved ways to be able to function. It is truly fabulous to see how these people can live in a seemingly inhospitable place. Reporter: Like the Indians I visited, those hunters use hunting skills specific to their environment. Their preferred target is the monkey, high in protein, which they hunt high in the canopy using poisoned darts. The most experienced hunters can accurately fire a dart over 100 feet. They're going for the kill right now. I consider them some of the most spectacular forest hunters of anyone in the world. When you start hunting with them, when you're actually in the action with them, you recognize that these people are truly the masters of the forest. Reporter: Despite their isolation and lack of modern technology, it becomes clear on the show that these people mostly want the same things that we do. You can see how people are raising their families, how they're finding their food, what their activities are that they are so good at that enable them to live in these really remote locations. And "Survive the tribe" airs Thursdays on national geographic challenge.
