Evidence of a worldwide flood

[Hans Blaster]

We already know that the only ages @Platte accepts are those recorded in written accounts. My guess is that his gotcha will be taking Genesis as a written account and asking "the Flood was only 4,000 years ago, so how can you date the grand canyon to 70 million years?"

So it would seem, but he keeps dodging that and similar questions. I want to hear it from Platte.

Seems like they would want more to go on, but I'm not a paleontologist.

Science works by building understandings from evidence. When there is new evidence, the understandings may need to be updated, and hopefully improved.

You don't have an example of that happening, do you? It's just bluster and posturing, isn't it?

They go on what they've got. That's how science works.

Should I keep going?

A human jawbone found in a cave on the Tibetan plateau has revealed new details about the appearance and lifestyle of a mysterious ancient species called Denisovans.

What theory changed?

Which theory was updated? You can't "keep going" until you've started.

Interesting. Still didn't see any theories being updated.

My opinion was about Mr. Falwell, not

Out species left Africa 40,000 years earlier than previously believed for one

That's not what either article article says.

Let me try again: which scientific theory was updated?

Our species originated in Africa 300,000 year ago according to a skull that was found

Previously, the only known Denisovan fossils came from a cave in Siberia, and amounted to a finger fragment, some teeth and a few jagged pieces of bone. Crucially, scientists were able to extract DNA from inside the bone and by comparing this with other ancient DNA and present-day populations they learned that the species must once have been widespread across Europe and Asia.

The recent discovery of a 2.8 million year-old fossilized jawbone in Ethiopia is helping scientists clear up a clouded period in the evolution of modern humans.

Jawbone from China reveals that the ancient human was widespread across the world — and lived at surprising altitude.

Scientists have uncovered the most complete remains yet from the mysterious ancient-hominin group known as the Denisovans. The jawbone, discovered high on the Tibetan Plateau and dated to more than 160,000 years ago, is also the first Denisovan specimen found outside the Siberian cave in which the hominin was uncovered a decade ago — confirming suspicions that Denisovans were more widespread than the fossil record currently suggests.

Yeah well it made me be open to more than one possibility but it's kind of funny how all the theories change when a jawbone or a tooth is found.

Yes. Scientific theories do change since all of them are intentionally presented as a web of collected evalulations wherein each strand of data is provisionally held in connection with all of the others and is continuously open to further revision. The same goes, though for our understanding of the Bible.

And that's okay since the reality of God's existence or of the nature of His Creation doesn't depend upon our human level understanding to "make it true."

Sounds like we're learning more about something we didn't know a lot about. Not changing any scientific theories. Do you know what a scientific theory is? "Scientists Believe Humans left Africa XXXXXXX years ago." is not a scientific theory.

I'm not sure why you see why that's a problem. Given how little we know, any new evidence is bound to have surprises in store.

I didn't say it was a problem, BB is having a problem with what I said and seems to be denying that when new discoveries are made theories about our ancestors change.

I never said Scientific Theory. Do you read posts before commenting? "Yeah well it made me be open to more than one possibility but it's kind of funny how all the theories change when a jawbone or a tooth is found." "Scientists Believe Humans left Africa XXXXXXX years ago." is a theory is it not? Our species originated in Africa 300,000 year ago according to a skull that was found sounds like a theory to me.

Conclusions about our ancestors change, but nothing we have discovered has changed the theory of evolution.

Yes.

"Scientists Believe Humans left Africa XXXXXXX years ago." is a theory is it not?

No. I don't think it really fits even a loose nonscientific definition of theory.

I didn't say it changes the theory of evolution, it changes the conclusions that have been made from previous discoveries. You can split hairs over definitions but it changes the theories that have been put forth about when and where evolution took place and how long ago.

 

[BPPLEE]

Yes.



No. I don't think it really fits even a loose nonscientific definition of theory.

Oh then I guess it must be a fact.
What is a good definition for theory?


In everyday use, the word "theory" often means an untested hunch, or a guess without supporting evidence. But for scientists, a theory has nearly the opposite meaning. A theory is a well-substantiated explanation of an aspect of the natural world that can incorporate laws, hypotheses and facts.

 

[ottawak]

Oh then I guess it must be a fact.

Are those the only two options you know about?

OK, fine. But remember: it's a feature not a bug and it shows science is alive and healthy.
