Neuroanthropologist and co-chair of the N2 Conference Terrence Deacon discusses the noosphere, biological evolution, and the upcoming N2 conference hosted by scientific multimedia non-profit organization Human Energy to commemorate the 100th Anniversary of the Discovery of the Noosphere. 100 years ago, Philosopher Pierre Teilhard de Chardin introduced the concept of a planetary mind called the Noosphere.

And with a more fragmented landscape, could there be a new "sphere" on the horizon?
