Speciation is NOT an example of a change agent of gene pools.

Here's why:

1. Gene flow: This is a mechanism that can alter the gene pool. It involves the transfer of genetic variation from one population to another. If genes are brought into a population from a different population, they can introduce new traits.

2. Genetic drift: This is another mechanism that can cause changes in the gene pool. It refers to random fluctuations in the numbers of gene variants in a population. Genetic drift can lead to the elimination of certain genes over generations due to chance.

3. Natural selection: This is a key mechanism of evolution. In natural selection, traits that enhance survival and reproduction become more common over time, while traits that do not benefit survival and reproduction become less common. This process can lead to significant changes in the gene pool over time.

4. Speciation: This is the process by which new species form. It involves the splitting of a single evolutionary lineage into two or more genetically independent ones. While speciation is a result of changes in the gene pool, it is not a mechanism that directly causes those changes. Therefore, it is not considered a change agent of gene pools.
