Re:Genetic variation. (Score 1)

While it is true that genetic anomalies can produce the combination that will stop the next "Ultimate Life Ending Plaque Of Doom" it can just as easily create combinations that are worse off and more frequently does. This explanation is similar in logic to running around in a field to avoid getting hit by falling rain. Regardless of where you run you still have equal chance but by some odd logic people see a moving target as less likely to be hit. Additionally your last point about viruses points out that our evolution is not going to be able to naturally keep up with the new ULEPD.
