Just hitting a few highlights...
"
Perhaps there were two original cat populations: one large and one small size."
Not possible. Remember the thread you started about the feline mutation that prevents them from having the ability to taste sweets?

This molecular evidence tells us that the large and small cats share a common ancestor.
"
We know that when ecological niches are empty speciation is extraordinarily rapid. A year for guppies, fourteen for some lizards..."
Eleven years for guppies and fifteen for lizards.

Perhaps you are talking of a different study.
The case of the guppies was 18 generations. OK if you are talking about short generation times, but quite a problem if you are talking about animals that take longer to reach sexual maturity. For instance, you either had to have several species of sauropod stuffed onto the ark, with all of their food, or you almost have to have a new species per generation.
As for the lizards, thae article says that "
Although the lizards changed quickly, the extent of the change after only 15 generations was not dramatic. "If I showed you pictures of the lizards you probably couldn't tell any difference," says Losos. "In fact, I didn't even see any difference when I was in the field." Only careful statistical analysis revealed the change." Not exactly the kind of changes you expect to see in going to a housecat and a cheetah from the sme ubercat.
Back to the guppies. The main change was in size and the males changed more quickly because they had "more genetic variability for this trait." There is no variability if you have only a single pair of animals.
"
Keep in mind that before Peleg, Australia was joined to Asia..."
So you accept Pangaea? Do you accept Rodinia too? It is based on the same kind of evidence.

"
volution says it took about a billion years for the first single celled organisms to evolve into a differentiated cell multicellular organism. Bacteria have a generation span..."
Yes, but...
There is more genetic diversity within bacteria alone than there is between a particular bacterium and a human. Here are some quotes on this subject I ran across from Dawkins (The Ancestor's Tale).
"If animals and plants are treated as a pair of kingdoms, by the same standards there are dozens of microbial 'kingdoms,' whose uniqueness entitles them to the same status as animals and plants."
"Bacteria taken as a group are the master chemists of this planet. Even the chemistry of our own cells is largely borrowed from bacterial guest workers, and it represents a fraction of what bacteria are capable of. Chemically, we are more similar to some bacteria than some bacteria are to other bacteria. At least as a chemist would see it, if you wiped out all life except bacteria, you'd still be left with the greater part of life's range."
The increase in genetic diversity required to give us humans from a single celled ancestor is less than the diversity found in all those bacteria.
"
There is no intermediate fossil of land to sea animals, such as the whale. There are only interpretations of intermediate fossils, the majority of which are so far-fetched that you have to be a true evolution believer to be willing to accept them without having hysterics laughing."
So, in the competitive world of peer review, why didn't some of Gingerich's competitors point this out if it is such a stretch?
If the interpretation is wrong, the what is the alternative? Are these more and more "kinds" to be accomodated? And why do the other pieces of evidence line up so well? I am mostly concerned with the genetic testing that agress that whales form a clade with even toed ungulates, just as the fossils also say that they do, and with why whales have dozens of pseudogenes for the same sense of smell as land dwelling animals?
"
As far as your questions regarding whales are concerned, keep in mind that these internal bits of bone have been defined by evolutionists to be pelvis, legs, etc., because they demand that evolution happened. The fact is that they are no more pelvis and legs than our arms are wings, despite we have the same basic design in terms of numbers of bones that bird wings have."
You did not mention the genetics nor the ontogeny.
There are quite a few papers that document fully formed legs on the rear of whales. These are not just "internal bits of bone."

"
Every time there is a separation of a sub-population from a parent population, due to migration or catastrophe, or whatever, and a new variety emerges, that new population carries a much reduced gene pool than the original population did."
But there is no gene pool when you are starting at a bottleneck of only two individuals.
Yes, I know your standard answer of there not being one gene per trait. Here is a link to my response from the last time.
