On Ice Age Genetic Longevity
An interesting piece at the New York Times discusses recent research into human genetic diversity. This research suggests that longevity and resistance to degenerative conditions in some human populations evolved in response to Ice Age conditions. These sorts of studies will lead to greater understanding of the way in which different people are affected by aging processes, and what medical science can do in the near term to improve our health and longevity. The work also suggests that overeating, now common in Western societies, is more damaging to long term health in human populations without these evolved resistances.
