The fact is that the empirical evidence points to the fact that the genetic make-up of an individual (which can be established with certainty) does not fully determine its survival and reproduction and the interactions that cause the individual's survival and reproduction cannot be established with absolute certainty and a probably can never be.
This is all true, near as I can tell.
However, one of the points I was making is that the
other factors that determine survival and reproduction fall into the fitness landscape. If we can know absolutely everything about both the genes and the landscape, evolution would be very determinable (if there is such a word). Of course, we probably never can know all that stuff.
We call evolution "stochastic" because it is
difficult to predict its outcomes to any precise degree. Not because it is really random. (That is why Tai's sig is so misleading.)
The basic problem with those that argue that evolution is non-random is that they (excluding Paul and Wowbagger) lack sufficient finesse to distinguish a scientific argument from a philosophical one and science from woo.
aritculett, cyborg, and Ichneumonwasp all have their magic phrase that excuse them from presenting any evidence that evolution is non-random:

Well, thanks for excluding me from your list of philosophers. But, I must defend my friends on this forum, when they are right (and, as you know, I am willing to call them out when they are wrong).
I severely doubt articulett, cyborg, Ichneumonwasp, etc. have the problems you think they do.
There is nothing in their posts, on this thread, that indicates they can not separate science from woo. Maybe they are just not as good as communicating science
to you, as I happen to be*. But, if you take the time to study what they are trying to say, you will find they are more-often-than-not based on solid science.
(* Not sure why that would be, though. It might be a matter of patience rather than writing ability.)
Of course, it does not help matters, when participants choose to spit ad homs and accusations, instead of arguments and explanations. (And, I will
not defend any of that behavior.) But, if you are really willing to learn anything from any Internet forum, you have to make some effort to separate the wheat from the chaff.
Mine has always been that because phenotype does not full determine survival and reproduction,
I agree. But, once again, I must remind you that the other factors that determine these things are known.
This is the argument which articulett and cyborg have been so vehemently rejecting. There is always some vague causal and deterministic structure of the individual's interactions with the environment and how that effect survival and reproduction, but that misses the central point of my argument which is that, regardless of the causes, effect is that individuals of the same phenotype do not necessarily share the same fate.
I think you are missing something.
articulett and cyborg can correct me if I am wrong, but I think they would both agree with my points: Yes, the genome and its subsequent phenotypes are not the sole determination of survival and reproduction. That is why evolution is stochastic: difficult to predict. There is also the fitness landscape to take into consideration. Taken together (perhaps with elements of self-organizing complexity laws?), the process is no longer random.
Maybe their language was not clear enough for some people. Or, I could be wrong, and they really do think the way you think they do. Either way, I'd like some feedback from my friends' assessment of these points.
The basic problem with the argument for those who insist that evolution is non-random so far is not a scientific argument; it is a philosophical one.
If that is true, then it follows that the basic reason why we can never predict exactly where a hurricane will strike is not due to lack of scientific accuracy, it must be because hurricanes are merely philosophical.
(If you think there is some aspect of the natural process of evolution that is really, truly, random, then you tell us what it is.)
