Which is a nice way to say not a lot about the local effect. There is still an impetus and an action and a reaction, i.e. my typing/your typing which may or may not have any degree of wide-ranging effects- and yes-

So far, I remain convinced only that all things were all things once upon a time, but that entropy has divided all things into every things.
We are creating the environment, not the evolution that works within it.
Gould's take on the non-directionlessness of evolution is part and parcel of almost all his works, but I remember seeing it in The Panda's Thumb, but most of all in a talk he gave here which was broadcast on C-SPAN.
