1. Surviving the ratchet : Modelling deleterious mutations in asexual populations
Abstract : One of the most unforgiving processes in nature is that of Muller's ratchet, a seemingly irreversible accumulation of deleterious mutations that all organisms have to deal with or face extinction. The most obvious way to avoid fitness collapse is recombination, though asexual populations usually do not have the luxury of recombining freely. READ MORE

2. Population Genetic Methods and Applications to Human Genomes
Abstract : Population Genetics has led to countless numbers of fruitful studies of evolution, due to its abilities for prediction and description of the most important evolutionary processes such as mutation, genetic drift and selection. The field is still growing today, with new methods and models being developed to answer questions of evolutionary relevance and to lift the veil on the past of all life forms. READ MORE

3. Population genetic history and patterns of admixture : Examples from northeastern and southern Africa
Abstract : The origin of humans lies in Africa, as has been shown by archaeology, paleontology and genetics. Here, we can find the largest genetic diversity and the deepest split among human populations. African genetic diversity has been shaped by a long and complex history. READ MORE

4. Adaptive divergence in fission yeast : From experimental evolution to evolutionary genomics
Abstract : How adaptation and population differentiation occur is fundamental to understand the origin of biodiversity. Work in speciation alongside the increased ease of generating genomic data have allowed the exploration of genomic changes relevant to adaptation. READ MORE

5. Aposematism, Crypsis and Population Differentiation in the Strawberry Poison Frog
Abstract : Evolutionary transitions between the two major predator avoidance strategies aposematism and crypsis are expected to be associated with changes in many important traits of animals. However, empirical studies on populations experiencing ongoing or recent transitions between these strategies are rare. READ MORE
