EVOLUTIONIST: Why haven't turtles evolved into something else after 75 million years?

i thought they had...aren't they call "Teen-Age Mutant Turtles"?

LOL-sorry don, I just couldn't resist after reading some of your answers... :-)

Turtles have evolved quite a bit adapting to different environments over the ages. Evolution is both fact and theory for man. So the turtle didn't evolve into a Christian eating intelligent monster or something, many small mammals did evolve into Lions that did eat the original followers of Christ. How does your statement disprove evolution? Also the same people who fed the original followers of Christ to the lions, were the same people who formed what is now called the "Christian church".

Jesus knew of evolution, off course He Knew The One True God As Well, not the one Christianity created to scare little children. The same church that teaches logic and reason are the tools of satan.

Species adapt to their environment to best suit natural selection. If the species fits into a niche perfectly then it has no reason to change. Hence, the coelacanth is a good example.

Evolution is a scientific theory and a fact.

Simply put, because there was no reason for them to evolve into anything else!

Turtles are already well-enough adapted to their environment for there not to be any "easy" mutation that will give them a definite survival advantage.

Come on mate! be fair a turtle is a really slow animal, 75000000years is hardly enough time

Many species reach a dead end in the evolutionary process. Or maybe under the right enviromental conditions, they might evolve further.

They may have. It wouldn't mean all turtles disappeared. It would mean that there are other species around that once shared a common ancester with turtles.

maybe because they have found thier "niche" and have not evolved much because they are well-suited to thier environment that new mutations do not stick.

evolution through mutations and natural selection is a responce to the environment, not a goal.

if a creature doesn't develop significant or any changes it means it is already well-adapted to its environement to survive.

I know why you didn't provide the link:

"Both specimens, described this week in the journal Biology Letters, belong to an extinct turtle in the Adocus genus, a large river turtle that resembles today's slider and cooter turtles."

"Resembles" does not equal "the same". As for why they have not changed drastically, they didn't need to.

why should they? They are not identical, but clearly their habitat hasn't changed, so why should turtles change? They are clearly onto a good thing being turtles.
