I would really like to know - I have asked the question many times and no
one has given me a sufficient
answer:
How does evolution change the number of Chromosomes? I have no problem with
adaptations between
species with the same number of Chromosomes. But how does the number get
increased?
Advanced creatures have many more than primitive. Absolutely necessary
functions are
in completely different places.

Both Behe and I, as trained biochemists, acknowledge the role of chance

explain many of the complex processes or structures of living organisms.
Here is a point where I agree with Lain. I made this point in my book:
A point of information to the list. My name is Iain not Lain, and I am not
a trained biochemist, as the above out-of-context quotation from my original
post seems to indicate. I was quoting Wells, which should have been clear.
I am a computer scientist, which a specialist area in machine learning,
neural networks, and (for a brief while) genetic algorithms.
I am therefore not well qualified to discuss Dick's lengthy quotation from
his book. I will merely restate that I don't believe Behe was denying God's
provenance in the appearance of non-irreducibly complex organisms. I think
the best way of attacking the ID argument is to attack the premise, not the
conclusion. Richard Dawkins states that to argue that a so-called
"irreducibly complex" organism could not have evolved in a sequence of small
steps is simply an argument from ignorance; or the "argument from personal
incredulity". To my mind this is a much more effective criticism than the
main thrust of Roberts' paper. I don't happen to agree with it personally,
but at least it attacks the real scientific issue.
