Adaptation, the gift of the Denisovans
The Tibetan PlateauThe city of Lhasa, the capital of the Tibetan Autonomous Region, is at ~12,000 feet above sea level. For comparison, Denver, Colorado, is on average close to ~5,500 feet above sea level. The “Mile High” city has nothing on Lhasa! But…
Manufacturing Chinese history cheaply
In Ross Terrill’s The New Chinese Empire he makes the assertion that Mao Zedong was the heir of the moralist Confucian tradition, while Deng Xiaoping’s stances looked more toward pragmatic Legalism. I don’t want to rehash why Terrill presented this strange framework as a central thesis in his book. Rather, there was an instance that […]
Genetic watersheds on the Great Himalayas
One of the great geological landmarks on earth are the Himalayas. Not only are the Himalayas of importance in the domain of physical geography, but they are important in human geography as well. Just as South Asians and non-South Asians agree that the valley of the Indus and its tributaries bound the west of the […]
Why Tibetans breathe so easy up high
I said yesterday I would say a bit more about the new paper on rapid recent high altitude adaptation among the Tibetans when I’d read the paper. Well, I’ve read it now. Sequencing of 50 Human Exomes Reveals Adaptation to High Altitude:
Residents of the Tibetan Plateau show heritable adaptations to extreme altitude. We sequenced […]
Very recent altitude adaptation in Tibet
Nick Wade in The New York Times is reporting on a new paper which will come out in Science tomorrow which investigates the evolution of genes implicated in adaption to higher altitudes among Tibets. I’ve posted on the genetics of this topic before, it obviously is of great interest. The major new finding is that […]
