A Critical Assessment of Storytelling: Gene Ontology Categories and the Importance of Validating Genomic Scans.

” Where there is life there is wishful thinking “ Gerald F. Lieberman Finding genes which are under positive selection is an important part of any molecular evolution biologists’ work as these genes can be responsible for adaptations in a … Continue reading

The genomic basis of adaptive evolution in threespine sticklebacks

Sticklebacks are originally marine fish that colonized freshwater habitats after the last glaciation. Adaptation to freshwater environment happened independently in various rivers and lakes around the globe, giving rise to similar phenotypes following natural selection. In a recent study, researchers … Continue reading

Genome-wide analysis of a long-term evolution experiment with Drosophila

For decades, most researchers have provided some general insights into the nature of adaptation in asexually reproducing populations with small genome, such as bacteria and yeast. They assumed that sexual species evolve the same way these populations do, i.e. their … Continue reading

Genome-wide analysis of a long-term evolution experiment with Drosophila

In this paper, Molly K. Burke and his collogues did an experimental evolution systems, which allows the genomic study of adaptation. They selected outbred, sexually reproducing, replicated populations of Drosophila melanogaster, which experienced over 600 generations of laboratory selection for … Continue reading

Parallel evolution in adaptive phenotypes: the case of the threespine stickleback

How do adaptive phenotypes evolve? This question, despite the increasing availability of genomic and other molecular data, remains still largely unanswered. Among the different aspects investigated, a major point of discussion in this topic is the extent of the contribution … Continue reading

Ecological success of recently emerged bacterial hybrids living in the wild

Microbial species are one of the most ubiquitous living group on Earth’s biosphere, showing incredible ability to thrive even in ambient conditions to the limit of human endurance. By virtue of their rapid growth, bacteria are ideal for unraveling the … Continue reading

What could our genomes actually tell about disease risk?

Despite the recent advances in whole-genome sequencing, two recent studies let us think that we are far from uncovering the genetic basis of common diseases risk. In fact, information relevant to complex diseases might hide within rare or even private … Continue reading
