There are several mechanisms for evolution. The first (and most important) being natural selection, which plays off random mutations.
Genetic drift is also another important aspect of evolution.
EDIT: It depends on what you mean by "mechanism." Mutations are thought to be the mechanism that causes the change in DNA, then natural selection and Gentic drift take over. Unfortunately, mutations do not hold up and evolution is ultimately left without a mechanism. This article on mutations gives an indepth explanation http://www.answersingenesis.org/articles/wow/are-mutations-the-engine
STRAIT FROM THE Biology BOOK :)
What else can I help you with?
What is the difference between evolution and theories of evolution?
Evolution is the process by which species change over time through natural selection. Theories of evolution, such as Darwin's theory of evolution by natural selection, are explanations for how evolution occurs and the mechanisms driving it. In essence, evolution is the phenomenon, while theories of evolution are the explanations for how it happens.
Why are there different ways for evolution to occur?
Different ways for evolution to occur exist due to various mechanisms such as natural selection, genetic drift, gene flow, and mutation. These mechanisms can act independently or in combination to drive changes in populations over time. Additionally, environmental factors play a significant role in determining which mechanisms are most prominent in a particular population or species.
What are the main mechanisms used by secular scientists to explain evolution?
All educated and not ideologically blinded scientists explain evolution by three primary mechanisms. Genetic drift, gene flow and natural selection.I have the feeling you do not know what secular means.
What are some problems in the theory of evolution?
Some potential problems in the theory of evolution include gaps in the fossil record, the origin of complex structures like the eye, and understanding the mechanisms driving rapid evolutionary changes. Additionally, determining the exact mechanisms of speciation and the role of epigenetics in evolution are ongoing challenges.
What mechanisms of evolution decreases the genetic diversity as a species?
Genetic drift, founder effect, and population bottlenecks are mechanisms that can decrease genetic diversity in a species. These mechanisms result in a reduction of variation within a population due to random events that affect the genetic makeup of the population.
The mechanism of evolution is?
The main mechanism of adaptive change is natural selection. There are other mechanisms of evolution though Google ' mechanisms of evolution. '
How are evolution and natural selection related?
Natural selection is one of the mechanisms that shapes adaptation and enables evolution.
What is the principles of mechanisms?
The leading theory concerning the mechanism of evolution is natural selection.
How is natural selection and evolution linked?
Natural selection is the process by which certain traits that provide a reproductive advantage become more common in a population over time, leading to evolutionary change. Evolution is the overall change in a population's genetic makeup over successive generations, driven by mechanisms such as natural selection. In essence, natural selection is one of the primary mechanisms through which evolution occurs.
Do any qualified scientists support evolution?
The vast majority of scientists support evolution. There is no longer any debate in the scientific community about whether evolution occurs, only the mechanisms in which evolution acts upon is debated.
What are the 4 mechanisms by which evolution can occur?
genetic drift, mutation, natural selection, and migration

What is the mechanism of evolution?
The main driving mechanism of evolution is natural selection. Though genetic drigt and gene flow can also cause evolution.
