Survival versus survivability: the state of surviving versus the process of survival

If survival is what defines evolution, then does evolution lead to the survival of the process of survivability? Is survivability, the ability to survive, the ultimate result of evolution? I often imagine that human beings have evolved the ultimate survival process through the transfer of knowledge from generation to generation using a process we call the scientific method. But perhaps bacteria are the ultimate survival mechanism? What are the limits of evolution through survival? For example, under what circumstances would the human species give up its own survival to promote the survival of another species/process? Is there such a thing as survival of survivability, survival of the process of survival?
