"And what I said was true; you are making it up as you go along. You have no clue what the mutation rates are."

No, what you said all along was/is untrue. You are confused by the difference between macro and micro derivation of a conclusion.

To wit: on the micro level it might be accurate to say that I don't have the specific mutation rates of alligators/crocodiles on the tip of my tongue...but at the macro level (e.g. the big picture) it is inaccurate to say the same thing...because species that are little-changed over 200 million years clearly have low mutation rates.

Which is to say, I know the macro rate of mutation. In contrast, you are desperately clinging to the fact that I don't know the specific micro level mutation rates as if that myopic viewpoint disproves the bigger picture.

It doesn't.

Show us where you got you information showing that the mutation rate for alligators is low.

I said you were making it all up. That's true, as you have no clue what the mutation rates are (nor did you have a clue about the breeding rate of T-rex or of alligators). Your continued evasions only further my case.

"To wit: on the micro level it might be accurate to say that I don't have the specific mutation rates of alligators/crocodiles on the tip of my tongue...but at the macro level (e.g. the big picture) it is inaccurate to say the same thing...because species that are little-changed over 200 million years clearly have low mutation rates."

Depends what the meaning of *is* is...

As was already pointed out, they are not the same species. Alligator/crocodile are not species designations.

"Which is to say, I know the macro rate of mutation."

No you don't.

Again, it has not gone unnoticed you are still avoiding the fact you claimed that alligators bred slowly, and alleged this supported your claim that T-rex bred even slower. Since it was pointed out you made an error, you have changed the topic to alligators instead of the T-rex.

You are still flailing...

"Crocodilia is an order of large reptiles that appeared about 220 million years ago. They are the closest living relatives of birds." From wikipedia.org

"Crocodiles are an ancient group of animals. The earliest species, the Sphenosuchians, evolved during the Late Triassic. They were highly gracile, terrestrial forms built like greyhounds. Several terrestrial species during the Cretaceous evolved herbivory (Simosuchus clarki and Chimaerasuchus paradoxus). During the Jurassic and the Cretaceous marine forms in the family Metriorhynchidae such as Metriorhynchus evolved forelimbs that were paddle-like and had a tail similar to modern fish. Dakosaurus andiniensis a closely related species to Metriorhynchus had a skull that was adapted to eat large sea reptiles. When examining extinct species, crocodiles have been a very diverse and adaptive group of reptiles." Also from wikipedia.org

Modern day Crocodiles are still around since the nitch that they found in the past is still around today. The others died out because there nitches disappeared.
