Why haven't humans evolved a resistance to the common cold?

Because it mutates- that is the protein coating changes- so often that we might biuld up a resistance to 1 strain of it but then it changes so we can never keep on top of it, it is like HIV.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
