What is your evidence that the terms micro-evolution or macro-evolution were used by Darwin or anyone else from that time? And while you are at it, you could give us your definitions of micro-evolution and macro-evolution. Then you could post evidence of why you think there is a barrier between them.
Unbelievable! That is what I give you in post#1652, the post you just replied to! What do you want me to do, read it to you like a little baby?
