You will have to support this claim; in detail.
It will require a defintion of macroevolution (and not just an example, especially a silly one that looks at extreme endpoints). It will then require the detailed evidence and reasoning showing support for your assertion.
This statement and pretty well all your other posts demonstrates to me that you don't belong in the science based side of the site.
You have this opportunity to show that I am wrong. If you don't start makeing better attempts at supporting you claims you will start with a 24 hour suspension from the science side very soon now. That will lengthen as required.
