Mother Nature is Not Our Friend

Mother Nature is Not Our Friend -- Sam Harris -- The Edge

While the process of natural selection has sculpted our genome to its present state, it has not acted to maximize human happiness; nor has it necessarily conferred any advantage upon us beyond the capacity raise the next generation to child-bearing age. In fact, there may be nothing about human life after the age of forty (the average lifespan until the 20th century) that has been selected by evolution at all. And with a few exceptions (e.g. the gene for lactose tolerance), we probably haven't adapted to our environment much since the Pleistocene...

But our environment and our needs -- to say nothing of our desires -- have changed radically in the meantime. We are in many respects ill-suited to the task of building a global civilization. This is not a surprise. From the point of view of evolution, much of human culture, along with its cognitive and emotional underpinnings, must be epiphenomenal. Nature cannot "see" most of what we are doing, or hope to do, and has done nothing to prepare us for many of the challenges we now face.
