    The Evolution of the Anthroposphere by Giulia Rispoli

    Published 2023-01-01
    “…The second case introduces the concept of ‘epistemic evolution’, crucial to understanding geoanthropology from a historical perspective, and combines it with the notion of the ‘noosphere’, particularly in the elaboration provided by Russian geochemist Vladimir I. Vernadsky. The noosphere is described as a new phase of biosphere evolution in which humans have become aware of their ability to reshape the Earth, especially through the invention of modern technologies. …”
