Good news from Richard Levins:

        Could you get thru to Dawkins to notify him that these reasons  -
and, I suspect, others too  -  should cause him to abandon his extremist
slogan that evolution is purely gradualist?
        The fossil record is dominated by discontinuities  -  saltations  -
e.g the first seed plant (a sequoia) appears 2.8 x 10^8 y ago with no
'proto-sequoia' precursor.  Eugenie Scott's slogan "we've got intermediate
forms coming out our ying-yang" is incorrect.
        I have never been able to understand the motive of Dawkins in
ignoring saltations.  In general, neoDarwinism is less implausible if
saltations are acknowledged.  Why aggressive atheists like Dawkins ignore
them is utterly unclear.  Anyone found any clues?

Richard also writes:

        BTW if you look into Gnosticism I think you'll find it's mainly a
different idea from this (which I believe should be credited to Plato).

        As far as I've seen, IDTers refuse to say anything about the
character, or even the number, of designer(s).
