"If you can show my 10 confirmed real-world examples of this being observed either in nature or in the laboratory, and demonstrate how each step of the way was neutral or beneficial, I will likely be convinced that genetic mutations are a viable mechanism to cause macroevolution. Even just one example for now will do. Anxiously awaiting your reply. Thanks."
I have replied numerous times to this...on the basis that it is not necessary or likely that every intervening step be neutral or beneficial. There will be no cases of this happening because if you add up enough random mutations some of them will be harmful. That is why I made all the comments about us each carrying millions of harmful mutations and yet having already had children.
I have also replied on the basis that the whole idea of a bit of code that makes an organ is utterly faulty. You can get a totally new organ never seen before simply by changing the cell expression and differentiation pattern while retaining the same DNA code, in all other respects.
You have not responded to any of my posts pointing this out - including the one about duck bills /feathers and human DNA.
You have not responded to my post in which I demonstrated that a mutation can add information immediately to the DNA in one step that may also add new function to a protein.
I have given real actual examples of mutations that add information, that are net beneficial to the organism regardless of environment, and that add new function. I have attempted to explain to you that there is no bit of the code that equals duck bill, each bit of the code makes a protein...how these proteins organise and how each individual cell expresses them varies from cell to cell. Think of a stem cell...each one has the same code but one may become a heart cell and another a bone cell. In a human none of them become a tail cell, even though ALL of the DNA needed for tail cells is encoded in human DNA.
You don't NEED to add new DNA to cross 'kind' barriers (I am assuming that monkeys and humans are different 'kinds'), you can use broadly the same DNA in a different expression pattern....
