ON THE THEORY OF PREBIOTIC EVOLUTION [PDF]

open access: yesFilozofia i Nauka
The main theorems of the theory of evolution of open catalytic systems are briefly presented. The difference between the “natural-historical” and “actualistic” approach to the problem of the origins of life was highlighted.

Group selection models in prebiotic evolution [PDF]

open access: yesPhysical Review E, 2000
The evolution of enzyme production is studied analytically using ideas of the group selection theory for the evolution of altruistic behavior. In particular, we argue that the mathematical formulation of Wilson's structured deme model ({\it The Evolution

The prebiotic emergence of biological evolution [PDF]

open access: yesRoyal Society Open Science
The origin of life must have been preceded by Darwin-like evolutionary dynamics that could propagate it. How did that adaptive dynamics arise? And from what prebiotic molecules?

Natural Pyrrhotite as a Catalyst in Prebiotic Chemical Evolution [PDF]

open access: yesLife, 2013
The idea of an autotrophic organism as the first living being on Earth leads to the hypothesis of a protometabolic, complex chemical system. In one of the main hypotheses, the first metabolic systems emerged from the interaction between sulfide minerals ...

Emergence and diversification of a host-parasite RNA ecosystem through Darwinian evolution

open access: yeseLife, 2020
In prebiotic evolution, molecular self-replicators are considered to develop into diverse, complex living organisms. The appearance of parasitic replicators is believed inevitable in this process.

The Grayness of the Origin of Life

open access: yesLife, 2021
In the search for life beyond Earth, distinguishing the living from the non-living is paramount. However, this distinction is often elusive, as the origin of life is likely a stepwise evolutionary process, not a singular event.

Prebiotic chemistry: a review of nucleoside phosphorylation and polymerization

open access: yesOpen Biology, 2023
The phosphorylation of nucleosides and their polymerization are crucial issues concerning the origin of life. The question of how these plausible chemical processes took place in the prebiotic Earth is still perplexing, despite several studies that have ...

Polyesters as a Model System for Building Primitive Biologies from Non-Biological Prebiotic Chemistry

open access: yesLife, 2020
A variety of organic chemicals were likely available on prebiotic Earth. These derived from diverse processes including atmospheric and geochemical synthesis and extraterrestrial input, and were delivered to environments including oceans, lakes, and ...
