Quasi-Equilibrium States and Phase Transitions in Biological Evolution. [PDF]

open access: yesEntropy (Basel)
We developed a macroscopic description of the evolutionary dynamics by following the temporal dynamics of the total Shannon entropy of sequences, denoted by S, and the average Hamming distance between them, denoted by H. We argue that a biological system

The Universal Grammar of Evolution [PDF]

open access: yesФилософия и космология, 2022
The evolution (sensu lato) of the cosmos can be divided in three phases: cosmological evolution (sensu stricto), biological evolution and cultural evolution. Analogies between biological and cultural evolution date from the nineteenth century although it

Algorithmically probable mutations reproduce aspects of evolution, such as convergence rate, genetic memory and modularity [PDF]

open access: yesRoyal Society Open Science, 2018
Natural selection explains how life has evolved over millions of years from more primitive forms. The speed at which this happens, however, has sometimes defied formal explanations when based on random (uniformly distributed) mutations.

Study of Modern Human Evolution via Comparative Analysis with the Neanderthal Genome [PDF]

open access: yesGenomics & Informatics, 2013
Many other human species appeared in evolution in the last 6 million years that have not been able to survive to modern times and are broadly known as archaic humans, as opposed to the extant modern humans.

Bacterial N4-methylcytosine as an epigenetic mark in eukaryotic DNA

open access: yesNature Communications, 2022
Eukaryotic DNA can be methylated as 5-methylcytosine and N6-methyladenine, but whether other forms of DNA methylation occur has been controversial. Here the authors show that a bacterial DNA methyltransferase was acquired >60 Mya in bdelloid rotifers ...

Spatial organization of the kelp microbiome at micron scales

open access: yesMicrobiome, 2022
Background Elucidating the spatial structure of host-associated microbial communities is essential for understanding taxon-taxon interactions within the microbiota and between microbiota and host. Macroalgae are colonized by complex microbial communities,

The Compatibility of Evolution and Thomistic Metaphysics: A Reply to Dennis F. Polis [PDF]

open access: yesStudia Gilsoniana, 2021
In this article the author discusses Dennis F. Polis’ defense of the compatibility of biological evolution and Thomistic metaphysics. Some of Polis’ methodological and metaphysical arguments are examined and it is explained why they are unfaithful to the

Natural history collections are critical resources for contemporary and future studies of urban evolution

open access: yesEvolutionary Applications, 2021
Urban environments are among the fastest changing habitats on the planet, and this change has evolutionary implications for the organisms inhabiting them.

Testing a non-destructive assay to track Plasmodium sporozoites in mosquitoes over time

open access: yesParasites & Vectors, 2023
Background The extrinsic incubation period (EIP), defined as the time it takes for malaria parasites in a mosquito to become infectious to a vertebrate host, is one of the most influential parameters for malaria transmission but remains poorly understood.

Horizontal transfer of BovB and L1 retrotransposons in eukaryotes

open access: yesGenome Biology, 2018
Background Transposable elements (TEs) are mobile DNA sequences, colloquially known as jumping genes because of their ability to replicate to new genomic locations. TEs can jump between organisms or species when given a vector of transfer, such as a tick
