About the seminar
As a planetary astrobiologist, David Grinspoon studies the relationships between biological and planetary evolution. He sees the geological epoch of the Anthropocene as the advent of a radically new type of planetary change.

In this seminar, he will discuss the concept of planetary intelligence and propose that the current moment in Earth history may not be merely an epoch boundary, a common occurrence in Earth history, but a major transition in the nature of the planet, the advent of Earth’s 5th Eon, which he suggests could be called the “Sapiezoic”. He will address implications for the project of building a sustainable planetary civilization as well as the search for extraterrestrial intelligence.
