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

Natural Knockouts: Natural Selection Knocked Out
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

Information-Geometric Optimization with Natural Selection
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 Selection and Spatial Cognition in Wild Food-Caching Mountain Chickadees.
Understanding how differences in cognition evolve is one of the critical goals in cognitive ecology [1-5]. In food-caching species that rely on memory to recover caches, enhanced spatial cognition has been hypothesized to evolve via natural selection [2,

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