I am wondering if anybody can argue in defense of determinism in
regards to evolutionary history.

I'm sure that Wilkins or any number of others could make the argument,
but that doesn't mean that any accept that it is even worth pursuing.
Determinism makes assumptions as big as an Intelligent Designer and as
unsupported by the evidence.

Jim and I have been having a little backchannel discussion on this. My
basic principle is that every event* has a cause, and so evolution is
determinate (but that doesn't mean it has an outcome that is determinate
in the abstract). In other words, this is the outcome that was
necessary, but there is no way we could know ahead of time that this was
the necessary outcome based on a knowledge of [the best possible]
evolutionary theory. Evolutionary theory constrains outcomes, but not
uniquely.

* I.e., any event within the causal universe. About universes themselves
I have no idea. One might also draw a line at the quantum level. I do
not want to, but physicists tell me I must. Some physicists, anyway.
