: given enough time, all those little changes, which you allow, add up to big 
: changes.  You seem to imply that evolution says that a dog gives birth to a 
: cat, or a dinosaour gives birth to a bird.  this would in fact be a disproof of 
: evolution.  the physicists (astronomers) and geologists assure us that there 
: has in fact been enough time for lots of little changes to mount up to big 
: changes (aka: speciation and evolution).

	But each little change has to provide some advantage to the
organism while still maintaining a viable organism.  How do you 
explain going from the reptile lung to the avian lung while at 
each step still maintaining a working lung?  This is only one
example in many unbelievable leaps of mutation that evolution
would require.  Take another one for example.  Since you can't
show me the fossilized intermediate creatures, I'll let you imagine
the intermediate creatures as you describe them to me along the 
mutation steps from a reptilian scale to a feather.  Noting, of course
that you don't have an effective air foil until you get to the 
amazingly complex interlocking structure of the modern feather.
