Convergent evolution of the genomes of marine mammals

Introduction Convergent evolution is the independent evolution of similar features in species of different lineages. Marine mammals from different mammalian orders share several phenotypic traits adapted to the aquatic environment is a very classic example of convergent evolution. Although there are potentially several genomic … 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

The genomic landscape underlying phenotypic integrity in the face of gene flow in crows

In this paper authors returned to the question about the role of interspecific gene flow for the evolution and species diversification. Authors studied hybrid zone between two bird classes of the all-black carrion crows (Corvus corone) and the gray-coated hooded … Continue reading

The genomic substrate for adaptive radiation in African cichlid fish

In African lakes, cichlid fishes are famous for large, diverse and replicated adaptive radiations. Nearly 1,500 new species of cichlid fish evolved in a few million years when environmentally determined opportunity for sexual selection and ecological niche expansion was met … Continue reading

The genomic substrate for adaptive radiation in African cichlid fish

Evolutionary diversification among species attracts the attention of scientist during long time. Adaptive radiation underlies evolution and comprises the rapid adaptation of a single lineage to its changed environment which provides new resources and opens new environmental niches. Among all … Continue reading

The genomic landscape underlying phenotypic integrity in the face of gene flow in crows

The role of interspecific gene flow in species diversification has long been debated and is increasingly appreciated. However, the effect of gene introgression on phenotypic divergences and genome heterogeneity remain unclear in case of early speciation. To investigate these questions … 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
