The parallel evolution in amniotes seen through the eye of functional nodal mutations

Introduction In this article the authors describe an evolutionary convergence in mammals, birds, and reptiles, based on genomic data from NCBI. The evolution of different species and lineages is due to mutations that can appear and accumulate in organisms over … Continue reading

Evolution of Darwin’s finches and their beaks revealed by genome sequencing

Introduction Darwin’s finches from Galapagos and Cocos Island are classic example of young adaptive radiation, entirely intact because none of the species having become extinct as a result of human activity. They have diversified in beak sizes and shapes, feeding … Continue reading

Crossovers are associated with mutation and biased gene conversion at recombination hotspots

Meiosis is an important biological process by which combination of various types of the genes called alleles, are segregated and packed in each germ cell waiting to be transferred and expressed in descendants. This combinations of alleles are products of … Continue reading

The genetics of monarch butterfly migration and warning colouration

The monarch butterfly (Danaus plexippus) has a large distribution worldwide. It occurs in North, Central, and South America, Caribbean, and it has recently dispersed to other locations, such as Oceania and Africa. Two traits of this butterfly are incredibly intriguing: … Continue reading

Comparative analysis of regulatory information and circuits across distant species

Development and homeostasis of all organisms is tightly controlled by transcription regulatory factors that are often highly conserved across deep phylogenies. However, it is unclear to what extend the basic components of these networks (e.g. network motifs and structure, binding … Continue reading

The evolutionary history of polar bears

The study of the Ursus lineage, including brown bear (Ursus arctos), black bear (Ursus americanus) and polar bear (Ursus maritimus), provides the ability of addressing the subject of adaptation to extreme (salty and glacial) environments in mammals. Moreover, in last … Continue reading
