A dynamical systems perspective on the celestial mechanical contribution to the emergence of life [PDF]

open access: yesarXiv
Biological activities are often seen entrained onto the day-night and other celestial mechanical cycles (e.g., seasonal and lunar), but studies on the origin of life have largely not accounted for such periodic external environmental variations. We argue that this may be an important omission, because the signature replication behaviour of life ...
