Natural Selection: A Deselection vs Proselection Analysis
Since the dawn of Darwinian evolution theory evolutionists have assumed that evolution favors adaptive traits. In this analysis article the author explores the usefulness of assuming that natural s…

Motif analysis of amphioxus, lamprey and invertebrate estrogen receptors and amphioxus and human estrogen-related receptors: Towards a better understanding of estrogen receptor evolution
Background. The origins of steroid-dependent regulation of the vertebrate estrogen receptor (ER) are poorly understood. Genes with statistically significant sequence similarity to vertebrate ER…

Selfish and Altruistic Bacterial Populations Maximize Fitness Under Stress by Local Segregation
Landscapes in ecology have a profound influence on the adaption and evolution of competing populations for resources. We are interested in how altruistic populations survive in the presence of self…

“Ribopepzymes” are probably a link from ribozymes to protein enzymes
The evolutionary relationship between RNA- and protein-based biocatalysts was key to the evolution of living systems. This relationship is thought to have depended upon the transfer of both genetic…

Speciation of chilean Rhinocryptidae (Avian) based on their behaviour
The current classification of the chilean representatives of the passerine family Rhinocryptidae includes eight species. Three of them contain subspecies that don’t exhibit clear differences. Moreo…

Structural dynamics and divergence of the polygalacturonase gene family in land plants
A distinct feature of eukaryotic genomes is the presence of gene families. The polygalacturonase (PG) (EC3.2.1.15) gene family is one of the largest gene families in plants. PG is a pectin-digestin…

Did nature also choose arsenic?
All known life requires phosphorus (P) in the form of inorganic phosphate (PO4- or Pi) and phosphate-containing organic molecules. Pi serves as the backb…

Telomeres in Evolution and Development from Biosemiotic Perspective
Whereas telomeres protect terminal ends of linear chromosomes, telomerases identify natural chromosome ends being different from broken DNA. Although telomeres play a crucial role in the linear chr…

Aggregation of Single Nucleotide Polymorphisms in a Human H5N1 Clade 2.2 Hemagglutinin
The rapid evolution of the H5N1 serotype of avian influenza has been explained by a mechanism involving the selection of single nucleotide polymorphisms generated by copy errors. The recent emerge…

Concurrent Acquisition of a Single Nucleotide Polymorphism in Diverse Influenza H5N1 Clade 2.2 Sub-clades
Highly pathogenic Influenza A H5N1 was first identified in Guangdong Province in 1996, followed by human cases in Hong Kong in 1997. The number of confirmed human cases now exceeds 300, and the ass…
