Limits of Biological Change

Dropped is too light a word. "Thrown" is much more fitting.

And a mammal remains a mammal, a vertebrate remains a vertebrate, a chordate remains a chordate.

Yes.

No jellyfish-thingy turned into a mammal. No sea slug turned into a vertebrate.
Excellent work Tiggy. I don't mind your taunts - as long as you are learning. And today you made great strides. I'm proud of you.

But species do split and evolve into other species. It's been happening for 3 billion years now, give or take.



You'll have to excuse Clownshoes here. As a baby he was dropped on his head. A lot.

To be honest, I'm not sure that can explain what we observe here ...

So Mags, what were those massive animals that roamed the earth 200 million years ago through to 65 million years ago. Where did they come from, Where did they go. And what brought the current bumper crop of mammals online over the last 65 million years or so?

So Mags, (1.) what were those massive animals that roamed the earth 200 million years ago through to 65 million years ago. (2.) Where did they come from, (3.)Where did they go. And (4) what brought the current bumper crop of mammals online over the last 65 million years or so?

1. Dinosaurs
2. From their parents who would have been dinosaurs
3. They went extinct.
4. Favourable conditions.

Hmm, there are ants in my kitchen cupboard.
I've never seen ants in my kitchen before.
I've seen a few flies in here.
The flies must have turned into ants.

The thread topic is about whether there are biological limits to change.
I suggest that the evidence speaks for itself - we just don't see one animal changing into another type of animal.

For that I get abused and humiliated.
Sure are some insecure people in TWEB.

This would be great,except the evidence suggests that this is constantly happening, everywhere, always has been and always will be. But when evidence refutes ideology we get clowns.

Only if you limit yourself to real time, eyewitness evidence. Sadly for you Clownshoes, we have over 3 billion years' worth of other evidence, including 600+ million years' worth of multi-cellular animal fossils.

For that I get abused and humiliated.

No, you get abused and humiliated for being a trolling idiot instead of an honest contributor. Why you choose that path is known only to you.

You went up in my estimation when I saw the gang attacking you. At least you make a stand.
Of course you have to lash out at others because you hate ideas that conflict with your own. I hope one day you will see that that is a waste of your energy. In the meantime you'll 'Do unto others as they do unto you.'

Anyway - back to the issue.
1. Is there a limit?
2. Person A. 'Yes there is - what we see shows the limit.'
3. Person B. ' 'No , what we see shows no limit.'

Well Person B is not really doing anything except denying and opposing. So what?

No herd of cows has waded out to sea and become whales etc.

While not cows turning into whales here is a great video concerning manatee evolution:
