Evolutionary pressures on simple sequence repeats in prokaryotic coding regions
Simple sequence repeats (SSRs) are indel mutational hotspots in genomes. In prokaryotes, SSR loci can cause phase variation, a microbial survival strategy that relies on stochastic, reversible on-off switching of gene activity. By analyzing multiple strains of 42 fully sequenced prokaryotic species, we measure the relative variability and density distribution of SSRs in coding regions. We demon...
متن کاملA MODEL FOR EVOLUTIONARY DYNAMICS OF WORDS IN A LANGUAGE
Human language, over its evolutionary history, has emerged as one of the fundamental defining characteristic of the modern man. However, this milestone evolutionary process through natural selection has not left any ’linguistic fossils’ that may enable us to trace back the actual course of development of language and its establishment in human societies. Lacking analytical tools to fathom the cr...
متن کاملRESEARCH ARTICLES Evolutionary Analysis of Amino Acid Repeats across the Genomes of 12 Drosophila Species
Repeated motifs of amino acids within proteins are an abundant feature of eukaryotic sequences and may catalyze the rapid production of genetic and even phenotypic variation among organisms. The completion of the genome sequencing projects of 12 distinct Drosophila species provides a unique dataset to study these intriguing sequence features on a phylogeny with a variety of timescales. We show ...

متن کاملTime scales in evolutionary dynamics.
Evolutionary game theory has traditionally assumed that all individuals in a population interact with each other between reproduction events. We show that eliminating this restriction by explicitly considering the time scales of interaction and selection leads to dramatic changes in the outcome of evolution. Examples include the selection of the inefficient strategy in the Harmony and Stag-Hunt...
