«Paleontology of an Anthropologist». Volume 3. «Cenozoic» is a new book by Stanislav Drobyshevsky. The Cenozoic is the era of the fading of the planet’s former appearance and, at the same time, the time of the flourishing of reason. After a mass extinction, Earth managed to recover and, it seemed, reached a new level, but its development was shackled by a succession of ice ages. Against the backdrop of an increasingly harsh climate, the pressure of predators, and competition with strong rivals on the planet, a phenomenon emerged that had not existed before—human reason.
