What is A change in the gene pool of a population form one generation to the next that does not necessarily result in speciation is an example of?

 Mutation

Explanation:

Mutations are spontaneous heritable changes in the genome that arise from several errors within DNA replication. These may be:

Others include: missense mutations, nonsense mutations, insertions, deletions, duplications etc.

Mutations are induced by several factors, including environment, diet, radiation among others. They may be acquired, affecting somatic cells and typically due to errors in cell division or hereditary. Hereditary mutations occur in germ cells (sperm and egg) and are inherited by the offspring. These are a form of normal variation within a population that may not necessarily lead to speciation events.
