As most bacteria evolve to a less deatly version of itself to promote spreading, why hasn’t TB evolved to a more harmless bacteria? It’s so old, so there was plenty of time. Killing the host seems pointless in a evolutionary sense.
Thanks!

Killing the host *before the bacteria can spread* is an evolutionary dead end. Killing the host after the bacteria has spread is perfectly fine, because “live just barely long enough to breed” is the only result that evolution encourages.
