Part III - Planetary Systems and Life
Published online by Cambridge University Press: 24 September 2020
Summary
This is a generalized version of the Terraspermia hypothesis for all inhabited planets. Wherever life has evolved, its origin was on the same planet as its evolution. If successful space travel and planetary invasion by dormant spores occurs anywhere, it is only within very small-scale planetary systems, and even this seems rather unlikely.
