Single and independent mutations lead to an adaptive and complex color phenotype in deer mice living on the light-colored soils of the Nebraska Sand Hills

Pleiotropy of genes is often the main solution to explain genetic basis of complex phenotypes (i.e., those composed of multiple traits). But dissection of those genes or loci are rarely studied, and it remains unclear which of single pleiotropic mutations or … Continue reading

Analyses of pig genomes provide insight into porcine demography and evolution

Pig domestication has started over 10 000 years ago and has had important consequences on human life, changing our agricultural and medical practices. Much has been argued on whether pig was domesticated independently across multiple locations or it was adopted … Continue reading

Hard selective sweeps do not seem to be the rule in human evolution.

by Ricardo Kanitz, based on the paper by Hernandez et al. published in Science (2011). One of the main topics in evolution is – as it has always been – human evolution. Many new methods are applied first to humans; … Continue reading

Classic Selective Sweeps Were Rare in Recent Human Evolution

With the rise of genomics and the availability of whole genome sequences, geneticists hope to be able to understand the recent adaptations humans underwent. Classic selective sweeps, where a beneficial allele arises in a population and subsequently goes to fixation, … Continue reading
