The correct answer is: B.Accumulation of small genetic changes over time.

Explanation:

Gradual speciation occurs when small genetic changes accumulate over long periods, eventually leading to the formation of new species. These small changes typically happen through mutations, genetic recombination, and natural selection. Over time, these changes can lead to differences between populations that eventually become reproductively isolated, resulting in the emergence of new species.

The other options:

A.Large, rapid mutations: These are more characteristic of other processes, such as punct...
