Question

what most enables bacteria and other simple organisms to evolve more quickly than larger, more complex organisms?
a. more mutations that are beneficial
b. a wider variety of habitats
c. a much shorter life cycle
d. fewer requirements for survival

Explanation:

Bacteria and simple organisms have shorter life cycles. This means they reproduce more frequently. With more generations in a given time, there are more opportunities for genetic changes (mutations) to occur and be selected for or against. Larger, more complex organisms have longer life cycles and fewer generations in the same time frame, so evolution is slower. Options A (beneficial mutations aren't necessarily more common in bacteria), B (habitat variety isn't the main factor for faster evolution here), and D (survival requirements aren't the key reason for faster evolution compared to life cycle length) are less relevant.

Answer:

C. a much shorter life cycle
