Natural selection is a mechanism of adaptive change in evolution.
Natural selection, which is the mechanism for evolution.
The mechanism and main driver of adaptive change in evolution is natural selection.
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 :)
Evolution is the adaption of organisms to their environment. Change in genes is evolution which causes adaption via natural election.

The main mechanism of adaptive change is natural selection. There are other mechanisms of evolution though Google ' mechanisms of evolution. '

Adaptive change and speciation.

The main driving mechanism of evolution is natural selection. Though genetic drigt and gene flow can also cause evolution.
None. Big population drops are usually caused by starvation.
What is the mechanism that causes evolution. Both knew evolution occurred and occurs but did not know how or why. Lamark's " desire to evolve " and " acquired characteristics " failed to explain evolution. Darwin's theory of evolution by natural selection was the better explanation.

Mutation, genetic drift, gene flow and the driver of adaptive change, natural selection.
