Survival of the fittest actually means, as I understand it, survival of the most adaptable. Being easily manipulated is not looking like a good survival trait these days, but I think the people who need to know that most are unable to understand it.
Obviously, we are seeing humans that are unable to adapt well, (or quickly enough) if at all. They are mired in a molasses of ignorance that does not bode well for said survival. It is only real when they see it, so to speak, up close and in their faces. Then, it is too late.
"Sorry Charlie!" as they said over and over to the tuna.
We have generally developed the capacity to abstract important survival information that gives us better fitness payoffs and more befitting icons for survival, so this looks like a critical point in that sense due to the increasing complexity of human existence overall and that will become even more prominent as we proceed deeper into this tumultuous century.
I don't see all human behaviors as entirely genetic, put more along the lines of the emerging insights of the field of epigenetics. However, at the most basic level of our organismic existence, we may be seeing a massive demonstration of self-selection to some degree.
