//If only you would post some skull pics, then mock a few Creationists.. They just might love you again//

LMAO!! because its so true, maybe toss in a few fsm graphic for good effect too.

Are you READY??!?!?!?

Mammal-Like Reptiles

As previously stated, a succession of transitional fossils exists that link reptiles (Class Reptilia) and mammals (Class Mammalia). These particular reptiles are classifie as Subclass Synapsida. Presently, this is the best example of th e transformation of one major higher taxon into another. The morphologic changes that took place are well documented by fossils, beginning with animals essentially 100% reptilian and resulting in animals essentially 100% mammalian. Therefore, I have chosen this as the example to summarize in more detail (Table 1, Fig. 1).  

M. Eyes =           ?           Nose =           ?        Teeth incisors = ?       K. Eyes =           ?           Nose =           pointy    Teeth incisors = small       J. Eyes =           Medium    Nose =           stubby        Teeth incisors = BIG       I. Eyes =           Medium    Nose =           less stubby    Teeth incisors = big       H. Eyes =           smaller    Nose =           more blunt    Teeth incisors = smaller         G. Eyes =           SMALL    Nose =           Pointer    Teeth incisors = Skinny           F. Eyes =           BIG    Nose =           Blunt    Teeth incisors = Thin         E. Eyes =           HUGE!    Nose =           pointy, again    Teeth incisors = Bigger         D. Eyes =           Smaller    Nose =           Getting wider    Teeth incisors = Bigger: two!         C. Eyes =           Huge, again!    Nose =           broader    Teeth incisors = very small         B. Eyes =           less huge    Nose =           less broad    Teeth incisors = ??         A. Eyes =           bigger again    Nose =           rounded    Teeth incisors = small

Are you convinced yet?

 

Oscillating eye sizes,

head shapes that shift back and forth,

teeth that are large, then small, then large again.

 

Yeah; I believe this stuff!

There are some Evo's who think... "It effectively demolishes the entire creationist argument. Excellent reading!"

After seeing these pix; do you?

Why do you always put the source of these charts in such tiny print?

There, better. :)

A. Eyes = bigger again

"Bigger again" -- 'again' on sample A, commencing the series?

Your glosses on the diagram appear to be running backward; perhaps that is why you have utterly misunderstood (and thereby misrepresented) this diagram.

I know, I know, it's a waste of time pointing this out to you. But you run the risk of confusing someone who actually reads these threads for information.

Thanks for posting that wonderful, utterly crushing evidence again. Not only is it a beautiful series, but you helpfully highlight for us how easy microevolution is too with your commentary on the less significant changes.
