Im thinking out loud here, but Im thinking there is a difficulty with the concept of "randomness" that occurs because people anthropomorphize nature alot. "Random" vs "non-random" is a distinction originating from the process of ... um... what should I call it..?.. lets say "actualizing goals" which is a phenomena unique to organisms with a sufficiently developed nervous system... When there is a goal that is trying to be achieved, actions undertaken with the intention of actualizing the goal are considered "purposeful" and actions that are not intended to actualize a particular goal can be said to be random. From what I can tell, this is where the term is most meaningful... to mean "purposeless."
Now, as I said, as far as we can tell, there is no reason to believe that "goal actualization" is a phenomena that occurs anywhere except in the minds and successive actions of particular organisms. The forces of the universe were not actualizing any goals when they lead to the birth of the sun and planets. Rather, that was just mass and energy interacting according to the forces of the universe. "Stuff bouncing around." The same goes for the birth of organisms on earth. And the same goes for evolution.
Evolution has no purpose or goal. This is an often misunderstood aspect of evolution. Almost everyone ive ever met has misunderstood evolution in this sense. There is no force akin to a will at work with evolution. When an organism is faced with an environment in which it is incapable of surviving, evolution does not "kick into gear" and initiate a process of "goal actualization" with the purpose of changing the organism or creating a new organism that IS capable of surviving in that environment. Thats not how it works. I may have a problem with evolution being considered a unique phenomena, or a unique force in the universe. Its not... Its just the regular, old fashioned forces of the universe, such as gravity, at work. "Evolution" just designates the working of those forces as they pertain to biological organisms, in particular, how mutation and environmental forces combine to affect change over long periods of time.
So... since there is no "goal actualization" going on anywhere except in our minds and actions... you either say that everything in nature (except some organisms' actions) is random or you can say "random vs purposeful" is a distinction that should only apply in the realm of "goal actualization." Distinguishing phenomena in nature as "random" is kind of moot. As long as were not talking about phenomena caused by organisms, its all random. Random doesnt mean "happens for no reason." Theres a perfectly good reason why mutations happen. Its the same reason why billiard balls bounce around the way they do. Its the forces of the universe at work. Gravity, electromagnatism, and the strong and weak nuclear forces.
So the point of all of this long ass "thinking out loud" above is that when I said mutation is random, I just meant that it is "purposeless." Since evolution has no purpose, since evolutionary adaptation is essentially totally accidental, the source of our hard-wired values for food and sex are in this sense exactly similar to the source of those accidental preferences as I described them in my earlier posts. Accidental/random circumstance. Food and sex are no more objectively valuable than a painting or a piece of music.
