Most bacteria can reproduce very quickly, so their populations increase rapidly. Describe the evolutionary process that prevents most human-disease-causing bacterial parasites from causing the human population to become extinct

What will be an ideal response?


Coevolution between parasites and their hosts favors selection for hosts that can survive infection (until after they have reproduced) and parasites that maintain their infectious capabilities.
