Biologists usually agree that all genetic mutations occur by “chance” or at “ random”1 with respect to adaptation. The claim dates back to Darwin's conception of

Evolutionary change is the outcome of several population mechanisms (mutation, recombination, natural selection, genetic drift, migration and historical events like colonization of new geographical regions) and can be studied at many different levels.

Mutations and Evolution Recognize that mutations are the basis of microevolution; and that adaptations enhance the survival and reproduction of Population Genetics. When Darwin came up with his theories of evolution and natural selection, he knew that the Selective and Environmental Pressures.
Mutations are essential to evolution; they are the raw material of genetic variation. Mutation is a change in DNA, the hereditary material of life. An organism's DNA affects how it looks, how it behaves, and its physiology — all aspects of its life. So a change in an organism's DNA can cause changes in all aspects of its life.

Thanks to next-generation sequencing technologies, Davila et al. precisely characterized the role played by recombination and DNA repair in controlling mitochondrial variations in Arabidopsis thaliana, thus opening new perspectives on the long-term evolution 2004-06-28 · Background The outbreak of severe acute respiratory syndrome (SARS) caused a severe global epidemic in 2003 which led to hundreds of deaths and many thousands of hospitalizations.
In the 1930s, the discipline of evolutionary biology emerged through what Julian Huxley called the modern synthesis of understanding, from previously unrelated fields of biological research, such as genetics and ecology, systematics and paleontology. The investigational range of current research widened to encompass the genetic architecture of adaptation, molecula Part of a series on Evolutionary biology Darwin's finches by John Gould Key topics Introduction to evolution Common descent Evidence Processes and outcomes Population genetics Variation Diversity Mutation Natural selection Adaptation Polymorphism Genetic drift Gene flow Speciation Adaptive radiation Co-operation Coevolution Coextinction Divergence Convergence Parallel evolution Extinction select from is mutation ’ and ‘mutations are essentially random in nature and most are either neutral or harmful in their effects’.2 In short, mutations are life’s creator, the raw material with which natural selection has fashioned the entire living world. The mutation concept as the ultimate source of evolution was This has important implications for evolutionary genetics, since inferences of divergence times could possibly be distorted by variation in mutation rate across haplogroups (supplementary note 5, Supplementary Material online).
