Where is the contradiction?

On the one hand you say that isolation is not necessary on the other you say that isolation is the way to go for spreading a mutation. Sounds contradictory to me. Sounds like you are trying to take both sides of the question - if it is isolated then you have evolution, if it is not isolated then ------ you have evolution.

Can you READ??? Do you know the difference between "makes possible" and "increases the chances"???
