Answer:
D) a genetic bottleneck
Explanation:
Genetic bottleneck refers to the sudden reduction in the population size due to some adverse climatic factors such as natural calamities. It changes the allele frequencies since the survivor population mostly have different allele frequencies than the original population.
In the given example, an earthquake kills 98% of the squirrels. The survivor population exhibits different allele frequencies for the gene responsible for the thickness of stripes. Therefore, it represents a genetic bottleneck.

Answer:
Experiments
Explanation:
The ancient Greek philosophers spent more time philosophising and thinking about scientific explanations to phenomena in the natural world.
How ever, they relied solely on reasoning while attempting to explain scientific observations. Contemporarily, science is highly empirical. The scientific process can only be complete when scientific observations are subjects to rigorous experiments in order go determine the actual relationship between variables and provide better explanation for scientific observations.
Hence the ancient Greek philosophers should have used experiments rather than sole reason in proffering scientific explanations to natural phenomena.
