You're talking out of your butt because you are unqualified to estimate how long it "should" have taken. Typical "internet expertise".
I am not. I do not know how long it should have taken. I do know that mutations NOW are not happening so fast. You might say they are happening fast and they might be in a few specimens. A VERY few. In a hundred years changes have mostly been static. How many major changes can you name? We are not talking about fruit flies or roses.
Edited to say; Name changes that have occurred unassisted by man. Also I think it would be fair to name only the beneficial changes, since I believe that is what my butt believes is being talked about.
