Your natural disaster idea is only slightly true. The most likely to survive would be those who were smart enough to survive, not necessarily who are physically strong enough. (By physically strong enough, I mean resistance to the elements, physical strength, excellent immune response (Helps destroy cancerous cells before they are trouble.), and durability. (Like resistance to arthritis, etc.))
The more intelligent, the more resourceful an organism usually is. Those who trained their minds and their bodies for the catastrophe would be the most likely to survive. I can tell you, I have known some people that had an average or below average IQ but they studied things so much that they knew tons of information. If these people happened to study survival skills, they would end up being the survivors.
A super virus can be and probably has been created that no human could possibly survive. Were are talking 100% mortality rate. I am almost positive that germ warfare like this has been created in a lab somewhere and it is classified. Weren't they working on making a smallpox strain that was supposed to be resistant to any known antibiotic and immune response?
