The Origin of Information Handling
arxiv(2024)
摘要
A major challenge when describing the origin of life is to explain how
instructional information control systems emerge naturally and spontaneously
from mere molecular dynamics. So far, no one has clarified how information
control emerged ab initio and how primitive control mechanisms in life might
have evolved, becoming increasingly refined. Based on recent experimental
results showing that chemical computation does not require the presence of
life-related chemistry, we elucidate the origin and early evolution of
information handling by chemical automata, from information processing
(computation) to information storage (memory) and information transmission
(communication). In contrast to other theories that assume the existence of
initial complex structures, our narrative starts from trivial self-replicators
whose interaction leads to the arising of more powerful molecular machines. By
describing precisely the primordial transitions in chemistry-based computation,
our metaphor is capable of explaining the above-mentioned gaps and can be
translated to other models of computation, which allow us to explore biological
phenomena at multiple spatial and temporal scales. At the end of our
manuscript, we propose some ways to extend our ideas, including experimental
validation of our theory (both in vitro and in silico).
