Which is NOT a characteristic of a "primitive" state of microbial evolution?
A) aerobic metabolism
B) small genome
C) branching near the root of the evolutionary tree of life
D) hyperthermophilic

Question

Quizplus · Accepted Answer

Aerobic metabolism is actually a more advanced characteristic that evolved later in microbial evolution, allowing for more efficient energy production through the use of oxygen. Primitive microbes likely relied on anaerobic metabolism for energy production. The other characteristics listed (small genome, branching near the root of the evolutionary tree, hyperthermophilic) are more commonly associated with primitive microbial states.
