"On the contrary, a little-changed species represents an insignificant number of random mutations over 200 million years."

They aren't even the same species as those living two million years ago. *Alligator* is not a species designation.

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. Your flailing about hasn't fooled anybody.

On the contrary, a little-changed species represents an insignificant number of random mutations over 200 million years.

You have a citation for this? Evidence? Studies of mutation rates in alligators?

"They aren't even the same species as those living two million years ago. *Alligator* is not a species designation."

You are welcome to substitute "crocodile" for Alligator. My points still stand. Yours still fall.

[js1138]

You haven't demonstrated anything at all about mutation rates.

[demkicker]

Pinging a few atheists.

[CarolinaGuitarman]

"You are welcome to substitute "crocodile" for Alligator. My points still stand. Yours still fall."

No, they are not the same thing. Alligator is not a species designation, nor is crocodile. The species of both alive today are not the same ones alive 200 million years ago. They speciated.

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...

"Label yourself, then. I'm disinterested"

I'm sure you are. I could be mistaken but saying alligators are perfectly suited to their enviroment and haven't changed, to me, would be closer to creationism than Darwinism.

BTW, I don't need to "label" myself to participate in a discussion. Maybe I should?

[Sacajaweau]

For all we know, they were cross-eyed. Don't horses have an unusual range of vision which is why they wear blinders?

[CarolinaGuitarman]

"You haven't demonstrated anything at all about mutation rates."

That's because he doesn't know anything about them and is making it up as he goes along.

[js1138]

This nonsense about alligator mutation rates comes from the same school of biology that claims, after gazillions of radiation induced mutations, that fruit flies are still fruit flies.

"You have a citation for this? Evidence? Studies of mutation rates in alligators?" - js1138

Since when does posting sources *ever* pin down Darwinists?! You'll ignore it or deny it (occasionally mock it) and move on.

Nonetheless...

Crocodiles first appeared nearly 160 million years ago and have changed very little ... www.skullsunlimited.com/crocodylia.htm - 36k -

If I see one more thing about "alligator mutation rates" I'm gonna shoot myself. Don't worry about supplying the gun, I own several (smiling?)

[Southack]

"That's because he doesn't know anything about them and is making it up as he goes along."

Personal attacks aside (you offer little else, it seems), **random** mutations must involve mathematical probabilities...something that can either be shown/supported or discarded.

That's not made up.

[js1138]

What studies do you have of mutation rates for crocks and alligators?

[CarolinaGuitarman]

"Personal attacks aside (you offer little else, it seems)"

That's a laugh coming from you. And what I said was true; you are making it up as you go along. You have no clue what the mutation rates are.

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.

"This nonsense about alligator mutation rates comes from the same school of biology that claims, after gazillions of radiation induced mutations, that fruit flies are still fruit flies."

On the contrary, speciation from external bias (e.g. iradiation) rather than from random happenstance is the antithesis of "nonsense." Such cause and effect is the entire subject of debate in this controversy.

Personal attacks aside (you offer little else, it seems), **random** mutations must involve mathematical probabilities...something that can either be shown/supported or discarded.

So if you didn't make it up, where are your citations for studies of mutation rate in crocks and alligators?

Show us where you got the information regarding mutation rates in alligators.

[Southack]

"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.
