Of course, most mutations are not advantageous, and those that are will still over time eventually lose out to dire environmental factors or competition from other organisms. Does your use of the term "mechanism" imply a purposeful motivated force on what is essentially a random series of events?

Mechanism is just a fancy term for how something is done. NS just says NS or survival of the fittest or some glop term. I want to know, if it is genetics, how does it happen, what particular things happen on the genome and how is it accomplished. If you had to take a real guess about what would happen if the following conditions were made, what would happen?

On most of these threads I have been told to shut up, believe that what can happen to a bacterium is very important to mammals, speciation is important or not important depending on the result, all of which does not lead me to drink at the fountain of NS as the mechanism of evolution.

But the bottom line is I am very happy that unicorn lives.
