COVID-19 pandemic and “survival of the fittest”

open access: yesJournal of Infection in Developing Countries, 2021
Occurrence and recurrence of COVID-19 cases have been observed globally. The complex relationship of host-pathogen and the environment plays a vital role in understanding the widespread recurrence of the SARS-CoV-2 among humans.

Natural selection promotes antigenic evolvability. [PDF]

open access: yesPLoS Pathogens, 2013
The hypothesis that evolvability - the capacity to evolve by natural selection - is itself the object of natural selection is highly intriguing but remains controversial due in large part to a paucity of direct experimental evidence.

An experimentally introduced population of Brassica rapa (Brassicaceae). 1. Phenotypic selection over three years following colonization of a novel environment [PDF]

open access: yesPlant Ecology and Evolution, 2018
Background and aims – Despite the importance of selection in driving evolution, little is known about the consistency of selection, particularly in the early stages of colonization of novel environments. This study examines the targets and consistency of

Information-Geometric Optimization with Natural Selection

open access: yesEntropy, 2020
Evolutionary algorithms, inspired by natural evolution, aim to optimize difficult objective functions without computing derivatives. Here we detail the relationship between classical population genetics of quantitative traits and evolutionary ...

Natural Knockouts: Natural Selection Knocked Out

open access: yesBiology, 2017
In functional genomics studies, research is dedicated to unveiling the function of genes using gene-knockouts, model organisms in which a gene is artificially inactivated. The idea is that, by knocking out the gene, the provoked phenotype would inform us

ABO AND RH BLOOD GROUPS DISTRIBUTION IN THE POPULATIONS OF LARESTAN AND LAMERD, FARS PROVINCE, IRAN [PDF]

open access: yesIranian Journal of Public Health, 1996
A total of 3204 ABO and Rh blood groups were investigated in Larestan and Lamerd populations, in Fars province, in Iran. The frequency of the A gene ranged from 16.54% to 21.96, the B gene from 15.85 to 27.77% and that of the d gene from 21.49 to 33.01% ;

Phylogenetic Analysis of Three Long Non-coding RNA Genes: AK082072, AK043754 and AK082467 [PDF]

open access: yesJournal of Genetic Resources, 2018
Now, it is clear that protein is just one of the most functional products produced by the eukaryotic genome. Indeed, a major part of the human genome is transcribed to non-coding sequences than to the coding sequence of the protein.

How do monomorphic bacteria evolve? The Mycobacterium tuberculosis complex and the awkward population genetics of extreme clonality

open access: yesPeer Community Journal, 2023
Exchange of genetic material through sexual reproduction or horizontal gene transfer is ubiquitous in nature. Among the few outliers that rarely recombine and mainly evolve by de novo mutation are a group of deadly bacterial pathogens, including the ...
