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

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 six factors of macroevolution?
I'm not sure that there exists such a thing as "factors of macro-evolution". Macro-evolution is simply what happens when reproductively isolated populations continue to diverge as a result of micro-evolution. They drift apart genetically, behaviourally and morphologically, so that the differences between them become greater and greater. The mechanisms that cause this are reproductive variation and differential reproductive success, the principal mechanisms of evolution.
What does Natural selection that has led to the evolution of diverse natural history strategies have in common?
mechanisms that maximum lifetime reproductive success.
Is gene mutation within a species know as micro evolution?
Genetic mutation is one of the mechanisms for evolution.Micro-evolution by definition means very small changes in allele frequency (gene mutation).
What are facts about Charles Darwin theory of evolution?
Fact #1: Darwin's theory of evolution proposes that populations of organisms originating from a shared common ancestor diverge, producing new species. Fact #2: Darwin's theory of evolution proposes that the most important mechanisms driving the divergence of populations are reproductive variation and differential reproductive success. Fact #3: Darwin's theory of evolution proposes that, following #1, all known life on Earth is ultimately related through descent. A gratuitous fact #4: The modern theory of evolution is no longer limited to Darwin's original proposals. New facts have been found, new mechanisms proposed, and existing models and hypotheses refined to accommodate the new data.
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 one of the 'guiding' principles of evolution.
What are the 4 mechanisms by which evolution can occur?
genetic drift, mutation, natural selection, and migration

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 is the mechanism of evolution?
The main driving mechanism of evolution is natural selection. Though genetic drigt and gene flow can also cause evolution.
What has the author James J Bull written?
James J. Bull has written: 'Evolution ofsex determining mechanisms' -- subject(s): Evolution, Evolution (Biology), Genetic Sex determination, Sex Determination, Sex chromosomes, Sex differentiation
What is the evolution theory of the creation of the universe?
Evolution does not concern the origin of the universe. Evolution is a theory concerning the origin of species--diverse biological organisms--via mechanisms of inheritance with modification. The origin of the universe is best dealt with by the Big Bang theory.
Do mutations cause change in allele frequencies within a population?
Yes, they can. Mutation is one of the four main mechanisms of evolution.
