It's a common tactic among people defending anything,
including creationism. That doesn't mean everyone indulges
in it.

As far as I can tell, the only form of evolution Johnson
accepts is "microevolution". That no one has a clue what
else Philip accepts is absolutely deliberate. And no, it
is not just Darwinism that he challenges, it's science in
general. He believes that science can identify God; not
only that but that science _must_ identify God in order
for Christianity to be true.

> If creationism isn't testable,

Creationism is testable. For example, the YEC hypothesis
is toast. It wouldn't be toast if it wasn't testable.
Further, Johnson et al. have made the claims that a new,
improved method of science would be here soon to replace
methodological naturalism in science. Others have made
claims that IC/ID can be a testable hypothesis. Yet,
despite the hype, we've seen nothing of the details.

Speciation has been observed. In the genome we've found no
apparent relationship between various species that can't be
explained by recombinatorial or mutational mechanisms we've
seen in the lab. It could have failed those tests but
didn't.

You mean Lewontin? No that's not Richard's view at all. But I
would agree that an ignorant populace should try to educate
itself rather than repeatedly "rebutting evolution" with many
of the same tired arguments that the ICR publishes.

$30-$40: not cheap. Try a library.

I don't and I'm sympathetic to neo-Darwinism. There are many
Darwinists who are Christian as well, so I don't think we
can reasonably dispute the validity of Darwinism on the
grounds that is requires or implies philosophical naturalism
(which is the core of Johnson's agenda).

I can't fathom such a lack of imagination. Read Howard Van Till's
posts recently?

Current data supports at least one common "bottleneck". That's
based on evidence of common biochemistry. It's possible that
there were multiple origins of life on earth but that only
one branch survived. Another multiple origin idea is that
some early forms may have merged or shuffled their components,
and that this fusion came to dominate life on earth.

You haven't been reading Howard Van Till's, Bill Hamilton's,
Terry Gray', Loren Haarsma's, or Brian Harper's posts then
(here or in the ASA list). All scientists and unabashed
Christians.

I agree they would have an effect (witness the Great Wall of
China). Now tell me how you think mind and consciousness affected
the course of evolution before mind and consciousness arose.
Particularly, tell me how you think choice and will guides
bacterial evolution.

Hard questions indeed, which makes it so important not to
shortchange the process by invoking "New [actually Old] Age"
pseudo-explanation as a bandaid to cover up total ignorance.

After science addresses the issues of consciousness and mind, will
we it still be stuck with gravity? I suspect that should science
make great progress in these subjects, we will still have
random variation and natural selection as a significant component
of evolution.

If as you said earlier, that Darwinism is not testable, how
could it be in shambles? How can one demolish an untestable
theory?

Nobody has passed such a law. Others have already proposed mechanisms
which are potentially testable and if found, will be mixed with
neo-Darwinism to form an appended theory of evolutionary mechanisms.
For example, neutral theory was absorbed fairly readily.
