Hi Anthony;
Since you didn't address my outstanding post:
http://groups.google.com/group/talk.origins/msg/0258ac6283ecf788
concerning the multilevel contradictions in your evolution denying
system where you appear to begin from:
*NOT* knowing if presumed ancestors where reproductively compatible
TO *knowing* that macro-evolution is impossible
but when presented with specific examples of macro-evolution claim to
*NOT* know if macro-evolution occurred.
So that you can clear up this confusion, here is a copy of that post:

Below you indicated that you don't know if cats and civets have a common
ancestor. This appears to leave open the possibility that cats and
civets might have a common ancestor. Since cats and civets are NOT
reproductively compatible how could they (according to you) have a
common ancestor?

Are you saying that you think the ancestors of dogs/racoons, cats/civets
may have been reproductively compatible in the past?

Three weeks ago you told me that you do not know if dogs and racoons
have a common ancestor. If macro-evolution cannot happen, why don't you
know if dogs and racoons have a common ancestor?
