Watch the EC epilogue and tell me again it's not about all this.
Synthesis
must be about
your
theory?
Who's being rigid and unreasonable in this argument, again?

Fossil evidence doesn't indicate that life has started more than once on Earth as far as I know.
We don't have fossil evidence of the very first lifeforms for obvious reasons (here's a hint: They were microscopic and soft-tissued so they don't leave behind any fossils) but rather what we have is evidence that life has existed in a number of periods where Earth's climate and atmospheric compositions have been substantially different from today.
Essentially, in the long ago times, the Earth could not support human life, or indeed any life that currently exists on it. It was, for practical purposes, an alien world - and yet there was life there. Presumably tiny, ugly life, but life none the less.

1) Evolution isn't actually survival of the fittest.
Not sure what you mean here. Perhaps I use the term in a different way than you do, because evolution isall about survival of the fittest. Can you explain what I'm seeing wrong?

2)
If a species doesn't reproduce any longer, or has exceedingly long
times between generations, the evolution of the species can effectively
be zero.
Yes, that is an evolutionary dead-end. But, as I have said, evolution is a broader abstract and not limited to species. Even when a species evolution is "effectively zero", they CAN change in the future, as long as reproduction can occur (if not, they become extinct, ergo evolutionary dead end).

3) There is a theoretical limit in which evolution does
not happen in a population. It is called Hardy Weinberg principal.
Anyone with even a rememdial biology course should probably have heard
of it. I'm sure with a bit of information theory and statistical
mechanics, you could make analogous limits where a biological system has
reached a limit where it can no longer have a change in its overall
genetic makeup.
This discludes the constant of genetic anomalies, however. As long as reproduction occurs, mutations may occur, and mutations which benefit an individual's survival will continue.
I'm not sure what you mean by a "biological system reaching a limit", either. As far as my understanding of biology goes, it's not a matter of putting parts on top of other parts and seeing what sticks and hoping it doesn't fall apart.
