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

The genome sequence of African rice (Oryza glaberrima) and evidence for independent domestication

Oryza glaberrima is an African species of rice that is not of the same origin as the Asian rice (Oryza sativa) and was independently domesticated from the progenitor Oryza barthii about 3,000 years ago.In this study recently published by Nature … Continue reading

Ancient human genomes suggest three ancestral populations for present-day Europeans

Introduction & Methods The demographic history of the human species has always fascinated us. It is known that the ancestral human lineage appeared in East Africa, and that it subsequently migrated out of Africa towards Eurasia, separating into distinct lineages … Continue reading

Genetic incompatibilities are widespread within species

The role and importance of epistasis (non-additive interactions between alleles) in shaping genetic variation, and its effects on fitness have been the focus of much debate. Russell et al. recently investigated the genomic footprint of epistatic fitness effects. Starting from … Continue reading

Genetic incompatibilities are widespread within species

Epistasis is the phenomenon whereby one polymorphism’s effect on a trait depends on other polymorphisms present in the genome(Hemani et al. 2014). Although it has been proved to shape genetic variation and contribute to differences within and between populations for … Continue reading

The Amborella Genome and the Evolution of Flowering Plants

Amborella trichopoda, an endemic species to New Caledonia, is the most early-diverging taxa of flowering plants (angiosperms, Figure 1). As such, the sequencing of its genome was of considerable interest for the investigation of the emergence and evolution of this … Continue reading

Patterns of population epigenomic diversity

In my point of vue, this paper is interesting because it’s in my domain of interest but very difficult to understand because they put lot of technical word without definition and they say very often see references, as it’s described … Continue reading

Towards discovering the evolutionary history of dogs and dog domestication process

In the times in which publishing a paper is not always totally related with the new knowledge´s contribution but leaded by how the researchers sell this new knowledge, it is quite refreshing to find a paper that outstands because deals … Continue reading
