Subject: Why haven't harmful heat resistant bacteria evolved?

Antibiotics have been used for less than 80 years (65 years since widespread
use). Drug resistant bacteria have evolved already. Evidence suggeats that Man
has used fire for at least 1.8 million years.

The mechanism of undercooking food would appear analogous to not taking a full
"course" of antibiotics. It should promote the evolution of heat resistant
bacteria requiring higher and higher "safe" cooking temperatures.

Microbes have been documented in environments of over 250 degF (albeit at high
pressures) yet safe cooking temperatures are only in the 160 to 180 degF range.

Why not 190 or 200 or 210 degF if evolution has had so long to work?
