Why did viruses evolve to kill their hosts?
Most don't, it is a hindrance. Most lethal viruses (and the ones you hear the most about precisely because of their lethality) come from animals, for example smallpox from cows, HIV probably from monkeys (exact source still under study, although a popular theory is that in africa, where primate m…
The Short Answer
Most don't, it is a hindrance. Most lethal viruses (and the ones you hear the most about precisely because of their lethality) come from animals, for example smallpox from cows, HIV probably from monkeys (exact source still under study, although a popular theory is that in africa, where primate meat is still eaten sometimes, blood from the primate came in contact with human blood). In these animals, they aren't lethal.
