All evolutionary change involves changes in EXISTING biological characteristics.
No evolutionary change ever involves changes in non-existing biological
characteristics. Which is why bird's wings, human hands, bat's wings, tiger's claws,
and horse's hooves are all modifications of pre-existing structures
rather than the magical poofing into existence of novel structures.

Biological 'novelty' is a bastardization of what really happens: modification
of existing molecules and structures by mutation. Mutation can
produce large changes quickly (e.g., achondroplastic dwarfism or neotony) or
small changes that get incrementally accumulated (human cranial capacity,
with the exception of creationists).
> Darwin conjectured that minor beneficial changes were probable (false)
Take height for example. In your non-Darwinian world, there can only
be major changes in height with nothing in between a mouse and an
elephant. There cannot be genetic variation that produces individuals with
quantitative variance in genetic traits, from taller than average through
average to smaller than average. That is because all possible intermediates
are unfit.

Been observed by the Grants. As well as a number of other studies (anole leg
length, English sparrow size and weight related to climate in the U.S). The
transformation by neoteny in fully-aquatic salamanders can be due to
changes by a single mutation.

Darwin knew that the fossil record had gaps due to the fact that
not every organism that ever lived being fossilized. You apparently
think otherwise. Why? Are you that stupid?

What geological processes that have occurred in the past are different from
those in the present (excluding those that occurred very early in earth
history before there was a solid crust)? There certainly were times when
some types of geological processes were more common than at other times,
such as sediments when there were more shallow seas.

What evidence do you have that says that new stratigraphic layers sometimes
get inserted between older layers? Do you think God lifts up the old
layer and sweeps the new one in underneath?

Other than burrowing organisms (and micromaterials like pollen)

Probably because you have a distorted idea of what constitutes a "novelty".
Evolution rarely produces novelty (although certain proteins clearly are
novelties produced by rearranging and combining parts of older proteins).
Evolution typically produces modification of something pre-existing, like
human hands.

Yet you believe that the *absence* of coherent supporting evidence
supports your ideas? How odd. Evolution remains the best supported
explanation of the evidence.

Except the fossil record is not static over time and no one can even define
Irreducible Complexity in an operational way.

What do you mean by "transformational"?

Rather Behe *asserted* that those two systems were irreducibly complex
and was shown to be ignorant of the facts about those two systems.

Lenski's experiment did show the emergence of novelty at the molecular
level. The inability to use citric acid was a defining characteristic of E. coli,
allowing E. coli to be differentiated from pathogenic Salmonella.
As well as, there were also morphological changes in cell size and form
(they become more rounded).
<sarcasm on> I presume that what you mean by 'novelty' would require that they develop
a brain larger than yours. Give it few more generations; it shouldn't be that
hard. <sarcasm off>

Almost all evidence is nonexistent to the willfully blind, deaf, and dumb.
