Towards physical principles of biological evolution [PDF]

Physica Scripta 93, 043001 (2018), 2017
Biological systems reach organizational complexity that far exceeds the complexity of any known inanimate objects. Biological entities undoubtedly obey the laws of quantum physics and statistical mechanics. However, is modern physics sufficient to adequately describe, model and explain the evolution of biological complexity?

Quantum mechanism of Biological Search [PDF]

, 2006
We wish to suggest an algorithm for biological search including DNA search. Our argument supposes that biological search be performed by quantum search.If we assume this, we can naturally answer the following long lasting puzzles such that "Why does DNA use the helix structure?" and "How can the evolution in biological system occur?".

The evolution of cooperation: an evolutionary advantage of individuals impedes the evolution of the population [PDF]

arXiv, 2022
Range expansion is a universal process in biological systems, and therefore plays a part in biological evolution. Using a quantitative individual-based method based on the stochastic process, we identify that enhancing the inherent self-proliferation advantage of cooperators relative to defectors is a more effective channel to promote the evolution of ...

Gene expression noise accelerates the evolution of a biological oscillator [PDF]

arXiv, 2022
Gene expression is a biochemical process, where stochastic binding and un-binding events naturally generate fluctuations and cell-to-cell variability in gene dynamics. These fluctuations typically have destructive consequences for proper biological dynamics and function (e.g., loss of timing and synchrony in biological oscillators).

Biologically Unavoidable Sequences [PDF]

Electronic Journal of Combinatorics vol 20 issue 1 (2013), 13pp, 2012
A biologically unavoidable sequence is an infinite gender sequence which occurs in every gendered, infinite genealogical network satisfying certain tame conditions. We show that every eventually periodic sequence is biologically unavoidable (this generalizes Koenig's Lemma), and we exhibit some biologically avoidable sequences.

Characteristics of Molecular-biological Systems and Process-network Synthesis [PDF]

arXiv, 2002
Graph Theoretic Process Network Synthesis is described as an introduction to biological networks. Genetic, protein and metabolic systems are considered. The theoretical work of Kauffman is discussed and amplified by critical property excursions. The scaling apparent in biological systems is shown.

Monte Carlo Simulation of Age-Dependent Host-Parasite Relations [PDF]

, 2007
The death of a biological population is an extreme event which we investigate here for a host-parasitoid system. Our simulations using the Penna ageing model show how biological evolution can ``teach'' the parasitoids to avoid extinction by waiting for the right age of the host. We also show the dependence of extinction time on the population size.

A review of Johnjoe McFadden's book ``Quantum Evolution'' [PDF]

arXiv, 2001
In ``Quantum Evolution: Life in the Multiverse'' (HarperCollins, 2000), ISBN 0-00-255948-X, 0-00-655128-9, Johnjoe McFadden makes far-reaching claims for the importance of quantum physics in the solution of problems in biological science. In this review, I discuss the relevance of unitary wavefunction dynamics to biological systems, analyse the inverse
