Answer:
The answer is B. Many small changes can create a whole new species.
Explanation:
Natural selection is a strong source of speciation in living beings.
After several generations, it is possible to observe distinctive features at the level of a population. A clear example of this can be observed in humans, where some physical traits are characteristic of different regions.
<u>If sufficient time passes</u>, it is possible that the differences of one population are sufficient to differentiate from another similar population, creating reproductive isolation and giving rise to a new species.
