The spotted gar genome illuminates vertebrate evolution and facilitates human-teleost comparisons

The spotted gar genome illuminates vertebrate evolution and facilitates human-teleost comparisons About 450 mya bony vertebrates radiated into Lobe-finned fish, from which tetrapods appeared later, and Ray-finned fish, which include Teleost (Fig.1). Nowadays they make up to 96 percent of … Continue reading

The genetic sex-determination system predicts adult sex ratios in tetrapods

Genetic sex determination, i. e. the determination of sexual phenotypes by the effect of sex-determining genes, is found in the majority of vertebrates. Sex determination genes have evolved multiple times independently and can be located on different chromosomes. Depending on … Continue reading

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

The recent formation and habitat diversity of the Galápagos archipelago, in conjunction with its relative isolation from the mainland, has helped the islands become rich in endemic species that have much to offer for the study of evolutionary biology. As … Continue reading

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

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

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

Gibbon genome and the fast karyotype evolution of small apes

Gibbons (Hylobatidae) are small arboreal apes that form a key node in primate evolution. One of the most distinctive phenotype is their high genome plasticity involving large-scale chromosomal rearrangements and karyotype changes. The four gibbon genera (Nomascus, Hylobates, Hoolock, Symphalangus) … Continue reading
