Answer:
C) genetic drift.
Explanation:
Genetic drift is the random change in the frequency of alleles in a population due to random sampling. Many circumstances can lead to genetic drift for example bottleneck effect, founder effect, etc.
The bottleneck effect occurs when most of the members of a population die because of any natural disaster like flood, fire, etc. This can cause a certain allele to be lost in the remaining population because of losing major populations. So here due to hurricane half of the mammal population gets eliminated which shows it is an example of the genetic drift.
I believe the answer is C, Leeunwenhoek because Copernicus was an astronomer, Kepler was a mathematician and astronomer and I THINK Bacon was a philosopher. Out of the 4, Leeuwenhoek was the only one strictly known for being a microbiologist, not only that but he was the first. I hope this helped :)
