Species evolve at different rates. For example, bacteria are unlikely to become extinct because they adapt more quickly than mammals to environmental changes. Which of the following best explains this difference?

A.) Bacteria reproduce more rapidly, allowing the species to evolve more quickly.

B.) Bacterial populations are more isolated, permitting increases in genetic variability.

C.) Certain bacteria grow more steadily over time, giving an evolutionary advantage over mammals.

D.)Individual bacteria have the same genes, providing opportunities for increased biodiversity in one population.
