Interatomic Coulombic decay-Interatomic Coulombic decay-ICD is characterized by its decay rate or the lifetime of the excited state. The decay rate depends on the interatomic (intermolecular) distance of A and B and its dependence allows to draw conclusions on the mechanism of ICD. Particularly important is the determi...

Coloration evidence for natural selection-Camouflage-Industrial melanism Between 1953 and 1956, the geneticist Bernard Kettlewell experimented on peppered moth evolution. He presented results showing that in a polluted urban wood with dark tree trunks, dark moths survived better than pale ones, causing industrial melan...

Coloration evidence for natural selection-Mimicry-Batesian Batesian mimicry, named for the 19th century naturalist Henry Walter Bates who first noted the effect in 1861, "provides numerous excellent examples of natural selection" at work. The evolutionary entomologist James Mallet noted that mimicry was "arguably the o...

Coloration evidence for natural selection-Mimicry-Müllerian Müllerian mimicry, too, in which two or more distasteful species that share one or more predators have come to mimic each other's warning signals, was clearly adaptive; Fritz Müller described the effect in 1879, in an account notable for being the first use of...

Coloration evidence for natural selection-Aposematism-In 1867, in a letter to Darwin, Wallace described warning coloration. The evolutionary zoologist James Mallet notes that this discovery "rather illogically" followed rather than preceded the accounts of Batesian and Müllerian mimicry, which both rely on the existenc...

Coloration evidence for natural selection-Defence of Darwinism-Edward Bagnall Poulton's 1890 book, The Colours of Animals, renamed Wallace's concept of warning colours "aposematic" coloration, as well as supporting Darwin's then unpopular theories of natural selection and sexual selection. Poulton's explanations of col...
