In 2018, in a paper entitled "Is Gaia alive? The future of a symbiotic planet" – published in the scientific journal "Futures" – he described different situations according to which "Gaia", the Earth, would be able to reproduce and to transfer her planetary genome to other uninhabited or inhabited planets. Prof. Cazzolla Gatti argued that our species could act as a germinal cell carrying a specific planetary genome, but it is unlikely for Homo sapiens sapiens to reproduce (or survive disconnected from Earth) on another Gaian system. In what is considered a breakthrough in astrobiology, the Italian scientist hypothesised that human beings will reproduce Earth's biosphere in the universe. "However—he said—as a spermatozoon, which loses its flagellum and acrosome while entering into the egg of another body, therefore changing its identity, a human being can be considered just as a carrier of its body's (i.e., Gaia's) genetic information, not of himself: a means more than an aim".
