Cavefish
What are cavefish? Like other cave-dwelling animals, fish that live in caves have often lost their eyes and body colour, but the evolutionary mechanisms underlying these reductions are unknown. There are 86 species of cavefish that belong to 18 different families, and many of them have lost their eyes independently. Comparing cavefish to their free-living ancestors can thus help us understand c...
متن کاملConservation and Convergence of Colour Genetics: MC1R Mutations in brown Cavefish
One of the most striking observations in nature is when similar phenotypes appear independently, such as wings in birds and bats, or melanism in moths and mice. These examples of so-called convergent evolution naturally lead us to ponder the question of genetic repeatability, i.e., the extent to which similar phenotypes that evolved in parallel share the same genetic mechanisms. Cave-dwelling o...
متن کاملCavefish and the basis for eye loss.
Animals have colonized the entire world from rather moderate to the harshest environments, some of these so extreme that only few animals are able to survive. Cave environments present such a challenge and obligate cave animals have adapted to perpetual darkness by evolving a multitude of traits. The most common and most studied cave characteristics are the regression of eyes and the overall re...
متن کاملA kinase kick for endocytosis
wo new studies indicate that cycles of phosphorylation and dephosphorylation may be required during clathrin-mediated endocytosis. A newly identified kinase is responsible for the required phosphorylation. Clathrin and the adaptor protein 2 (AP2) complex are the major coat proteins of clathrin-coated vesicles (CCVs). Among components of the AP2 complex are ␣ and  2 adaptins, which mediate AP2 ...
متن کاملCombination of Colour Favoured and Colour
In this research we described the effective Hamiltonian theory and applied this theory to the calculation of current-current (Q1,2) and QCD penguin (Q3,…,6) c quark decay rates. We calculated the decay rates of semileptonic and hadronic of charm quark in the effective Hamiltonian theory. We investigated the decay rates of D meson decays according to Spectator Quark Model (SQM) for the calculati...
