=This is just not true, in sequences where depositional

=Deposition tends to be sporadic/episodic and preservation

=transitional species are not ubiquitous.

But, Brian, you're forgetting an important point: The evidence you cite
contradicts one of the more moronic interpretations of the old testament, and
therefore MUST somehow be false.

understanding of astronomy is purely at the amateur level (or below). So
unless what I'm saying is directly related to VAX/VMS, don't hold me or my
organization responsible for it. If it IS related to VAX/VMS, you can try to
hold me responsible for it, but my organization had nothing to do with it.
