Both evolutionary biology and genetics have their roots 150 years ago in work with phenotypic variants of plants and animals. In contrast, microbial genetics originating as recently as the 1940s, rapidly revealed that filamentous DNA molecules are th....

The acquisition of scientific knowledge largely depends on the availability of appropriate research approaches and methodologies. Novel scientific knowledge represents cultural values. On the one hand, it enriches our world-view with impacts on our....

Charles Darwin had based his theory of biological evolution on the observation that phenotypic variants of a given species can sometimes over-grow their parental population, and he attributed this to selective advantage, i.e., to the impact of natura....

After reconsidering the very long time periods in cosmic evolution, we will focus our attention to the evolutionary development of living organisms on our planet Earth. The genetic variants (mutations), which are occasionally produced, are alteratio....

After a short reminder of the historical development of evolutionary biology, elements to a molecular theory of Darwinian evolution will be presented. Biological evolution is driven by the availability of genetic variants in populations. The occasi....
