Okay so there are people who claim to have found
Dinosaur DNA but...

Can we not just infer it?

So DNA falls apart... so what?

Look at a Dinosaur reconstruction. It is literally an
animal that fell apart. We dig up the pieces and put
them together as best we can.

Even what they call a "Fully articulated Skeleton"
is actually in pieces. The ribs aren't floating in the
air, or rock, occupying the exact same position in
relation to all the other bones that they had occupied
in life.

Isn't this true for DNA?

We pluck things like adenine, guanine, cytosine and
thymine in meteorites! One presumes these things
are older than last week. One presumes.

Maybe one (and two, me and you) are too
presumptuous? Or maybe this stuff lasts for a "Good
long time."

The point is, even if the DNA has completely fallen
apart, there are component pieces that remain. And
we could recreate that DNA, at least in theory, from
those component pieces.

Oh, it would take *Years* at least, and would be best
done by teams -- plural -- but it's possible that large
chunks of DNA could be reconstructed.

Someone may already be doing this...

I'm skeptical. No, not about this ever happening but
about the value to science. We as a species seem
extremely good at comparing two samples of DNA
and determining how they're different. But our
science is also ruthlessly incompetent at
determining HOW those differences came about.
And when it comes to evolution, THAT is the
important question.

But, "Dino DNA!" That is the take-away here. It's
coming.

Yes, Spielberg found dino DNA on the Lost Ark.

So DNA falls apart... so what?

DNA is typically 2 meters nucleotide chain folded into ∼10 μm
ball of yarn. If that polymer fell apart then how you figure in
what order the pieces were there? Something far shorter and
simpler as illustration to help to think: <https://www.sciencenews.org/article/art-dna-folding>

Oldest authentic DNA sequence is dated 1.1 - 1.6 millions
years old and that thanks to being deep frozen in permafrost.
Someone can probably double that to 2.6 my as that is oldest
permafrost. They will get lot of fame for that despite acting
by our current understanding.

Say someone invents some new trick how to double that.
Piles of fame for new trick ... but still ... it is only 5 mya.
Dinos went extinct 66 mya ... so that is quite far out of reach
for our current understanding + that hypothetical new trick.

If it was easy it would already have been done.

The point is that constituent parts remain. It's not a case were
there is nothing there. We do have something to work with, and
with enough time and effort we could sequence some dinosaur
DNA.

Oldest authentic DNA sequence is dated 1.1 - 1.6 millions
years old and that thanks to being deep frozen in permafrost.

Again, constituent parts survive the heat of entry into our
atmosphere. They do not need to be frozen.

Someone can probably double that to 2.6 my as that is oldest
permafrost.

The stuff is cooked -- literally heated red hot -- coming in from
space, and we can still crack open meteorites and find it.

Dinosaurs had nucleated blood. The plan would be to find
were the blood vessels used to be, crack them open and
search.

Say someone invents some new trick how to double that.

Nobody was talking about getting preserved DNA.

We find adenine (A), cytosine (C), guanine (G), and thymine
(T) in meteorites. It lasts a *Very* long time. It survives
entry into our atmosphere. Now assuming that microscopic
unicorns didn't enter the fossils and move everything
around, this adenine (A), cytosine (C), guanine (G), and
thymine (T) can be presumed to have pretty much
collapsed along the lines it had existed in before death.

...in much the same way that an articulated dinosaur
skeleton has.

So the trick would be to NOT find DNA but its constituent
parts, then work out from their relationship to each other
what they may have looked like before they fell apart.

Nobody said it would be fast, easy or cheap.

Instead of FINDING dinosaur DNA we infer it...

I hope this clarifies.

That's a question you should ask yourself... oh wait... you don't know

So you just threw yourself into a tizzy because I discussed
the idea of sequencing dinosaur DNA indirectly, and you
think this is normal behavior?

You're emotionally disturbed. You're so hungry to score
some imaginary points that you routinely disgrace
yourself like this, fly off the handle over on-topic threads,
AND you believe this is normal behavior...

You're fucked up.

I have no patience for your stupid fits.

Yeah, I get that a lot from willfully stupid trolls.

This is a thread about sequencing dinosaur DNA indirectly.
You jumped into this thread, acting mental, lashing out like

You're such a fraud!
