The genomic landscape of rapid repeated evolutionary adaptation to toxic pollution in wild fish

Introduction The pace of the evolutionary change depends on the existence of genetic variation, population size and intensity of the selection. While environmental change very often exceeds the rate of evolution for many species, killifish (Fundulus heteroclitus), living in U.S … Continue reading

The genomic landscape of rapid repeated evolutionary adaptation to toxic pollution in wild fish.

Introduction Environmental pollution is a widespread problem that living organisms have to contend with on a global scale. In contaminated sites especially, wild populations undergo intense selective pressure that may result in phenotypic adaptations to pollutants (Hendry et al., 2008). … Continue reading

How the Galapagos cormorant lost its ability to fly

Introduction Novel traits play a key role in evolution by facilitating the access to new ecological niches. Novelty is often recognized at a phenotypic level and usually related to gain of new function. But can nature innovate through the loss … Continue reading

Convergent evolution of caffeine in plants by co-option of exapted ancestral enzymes

A biochemical story on convergent evolution Introduction Convergent evolution is the process by which similar traits evolve independently in distantly related organisms, such as wings in bats and birds. This can target orthologous or unrelated genes, which gives a different … Continue reading

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
