1. Pawsitive selection : Genetics of dog-human communication
Abstract : Through domestication and recent selection, dogs have evolved a unique set of communicative skills to attract and redirect human attention. These social skills have not been seen to the same extent in socialised wolves and are therefore believed to have a significant genetic basis. READ MORE

2. The Effects of Mutation and Selection on the Rate and Pattern of Molecular Evolution in Birds
Abstract : By comparing sequence diversity and divergence on sex chromosomes one can study how the rate of evolution in affected by mutation and/or selection. The rate of mutation in male biased, meaning that relatively more mutations are created in the male germ line than in the female. READ MORE

3. Detecting Sex and Selection in Ancient Cattle Remains Using Single Nucleotide Polymorphisms
Abstract : All contemporary taurine cattle originated some 10,000 years ago when their wild ancestor, the aurochs, was domesticated in the Near East. Although the aurochs was widespread also in Europe, there is no evidence for a local domestication. The aurochs has been extinct since 1627 and therefore little is known about its biology. READ MORE

4. Effects of Selection and Demography on DNA Polymorphism in Black Mustard (Brassica nigra)
Abstract : The evolution of three genes from the CONSTANS-LIKE gene family is studied in Brassica nigra. We use a combination of population genetic and phylogenetic techniques in order to assess the relative importance of selection and demography on the pattern of DNA variation. READ MORE

5. Opportunity for natural selection in Sweden : a study of childhood mortality and differential reproductivity
Abstract : Opportunity for natural selection in human populations has so far mainly been studied on anthropological data for tribal populations or on census data for nations. The present study is mainly based on data on individual lifehistories but also, for part of the longitudinal study, on census data. READ MORE
