    Hunters lived on Tibetan plateau thousands of years earlier than thought Genetic

    Hunters lived on Tibetan plateau thousands of years earlier than thought
    Genetic and archaeological evidence points to pre-agricultural residents of the ‘roof of the world’.

    Intrepid hunter-gatherers may have lived permanently in the cold, harsh environment of the oxygen-starved Tibetan Plateau at least 7,400 years ago — nearly 4,000 years earlier than researchers had thought.

    The claim, made by archaeologists who have re-examined ancient hand- and footprints at a site in central Tibet, could shed light on how and why humans moved to live at high altitudes. And it fits with genetic studies suggesting that Tibetan people began to acquire physiological adaptations to help them cope with reduced atmospheric oxygen levels around the same time. But some researchers say the evidence is too scanty to confirm such early year-round habitation on the plateau.

    With an average elevation of 4.5 kilometres, the air on the Tibetan Plateau has around half the oxygen present at sea level. “It’s the ultimate test for human survival and adaptation in extreme environments,” says Mark Aldenderfer, an archaeologist at the University of California in Merced, and a co-author of the new study, published on 5 January in Science1.

    1. Fascinating report. I wish I could

    Remember what TV show examined the make up of humans who live at high altitudes. They are structured differently than we low altitude breathers are, so that they receive the needed amounts of oxygen to their brains and extremities. It’s actually in their DNA and their physiology, so it is not a matter of acclimating.

        3. That's one possibility.

        The other would be this show that aired on the Weather Channel, wherein they examined people who could do things or handle conditions most people can’t. People who can handle extreme heat or cold, extreme pressure. Ability to run longer,  stay underwater longer.

          4. dr. aldenderfer's expedition/extraction work

          is featured in the nova episode. i am going to check out the weather channel to catch the program you cite. thanks.
