Question

Quizplus · Accepted Answer

Evolution is best defined as a change in gene frequency over generations. This process occurs through mechanisms such as natural selection, genetic drift, and gene flow. It does not necessarily result in a gradual increase in complexity or a progression toward a complex human brain, although these may be outcomes in some cases. Adapting to survival challenges is also a key aspect of evolution, but it is not a complete definition of the term. Therefore, option B is the best choice for defining evolution.
