Oh, is LOOKS LIKE the criterion now ? Because we've got plenty of
*those*. Actually I remember bringing up some examples by name AT LEAST
twice in these series of threads you've been playing in, so I see no way
to account for this curious oversight of yours.

Again, what are you saying here ? That we're lying when we say jungles
don't fossilize well ? That evolutionary biologists picked chimpanzees
as our nearest relatives just because they lived in the jungle where
things don't fossilize well ?
Or are you whining because the Universe hadn't bowed to your wishes yet
? If YOU think it's lame that it's hard to find fossils in jungles,
think about how paleontologists feel !

Yes. Why, do you have some reason that it's impossible for humans and
chimpanzees to be related, even in theory ?

Because such an experiment would actually have no bearing whatsoever on
the question ? Wow, you haven't gotten better at this stuff. Remember
when you suggested an experiment to differentiate your theory from
Einstein's relativity, and it turned out your experiment would have had
the exact same result under both theories ? And you knew this when you
proposed it ?
Yeah, that's not how it's done.

Do we need a whole chimp ? Because we can't exactly accelerate their
development "as much as we will". Can we have just chimp chromosomes ?
But to make mutations happen to them as they happen in the wild we'd
still need the whole organism, and even if we could just do it in cells
we still couldn't accelerate the process "as much as we will", and
anyway we can't culture non-cancerous chimp cells indefinitely. Can we
simulate chimp chromosomes on the computer ?
Because in that case, finding out which changes between the chimpanzee
and the human genetic code happened when and why (i.e. re-creating the
history of mutations that happened to both) is exactly what many
researchers are doing.

We've decoded the human genome, and I think we've decoded the chimp
genome too. Both are huge and the effects of genes are still being
discovered and you need to account for the differences between
individuals so it isn't quite a matter of putting them next to each
other, finding the differences, and those are the "mutations it requires
to do it", but... isn't it ?

Once you learn what "conclusive" means and when the word can apply. It
would really help if you knew how to articulate a hypothesis, determine
its implications, understand which evidence can support that hypothesis
and which can't, and learned how to design an experiment that could
distinguish between hypotheses.
