The thigh bone, spotted six years ago on the banks of the Irtysh River in Siberia by a Russian artist who carves jewelry from ancient mammoth tusks

Who knew Art was an artist! Weingartner.. well that's not a Slavic name.

the practical limit is 50,000, used to be less, and 45,000 is not a bit of a stretch.

Then what do we make of carbon dating of dinosaur bones within 40,000 years? Shouldn't we consider dino bones at infinity years old for purposes of C14 dating? Perhaps use the measurements on dino bones to define the limit?

Dinosaur bones have never been RC dated within 40K, irrespective of the claims at that link.

Here’s the conference where his paper was allegedly removed, no sign of him, no gaps in the times.

Regarding the nonsense about Mary Schweitzer:

http://www.smithsonianmag.com/science-nature/dinosaur-shocker-115306469/?no-ist

> [Mary] Schweitzer’s research has been hijacked by “young earth” creationists, who insist that dinosaur soft tissue couldn’t possibly survive millions of years. They claim her discoveries support their belief, based on their interpretation of Genesis, that the earth is only a few thousand years old. Of course, it’s not unusual for a paleontologist to differ with creationists. But when creationists misrepresent Schweitzer’s data, she takes it personally: she describes herself as “a complete and total Christian.” On a shelf in her office is a plaque bearing an Old Testament verse: “For I know the plans I have for you,” declares the Lord, “plans to prosper you and not to harm you, plans to give you hope and a future.”

http://discovermagazine.com/2006/apr/dinosaur-dna

“God is so multidimensional,” she says. “I see a sense of humor. I see His compassion in the world around me. It makes me curious, because the creator is revealed in the creation.” Unlike many creationists, she finds the notion of a world evolving over billions of years theologically exhilarating: “That makes God a lot bigger than thinking of Him as a magician that pulled everything out in one fell swoop.”

Of course, blam’s *much* worse. ;’) I mean, look at all those freakin’ facts! It’s like he enjoys the sounds of locked brakes and screeching tires!

I don’t even ping him anymore. Not with all those facts. He gets me real nervous. I’m on a thread and it gets going, you know. It’s racing ahead and the hysteria/paranoia/rage gets going and I’m thinking, “who’s going to climb through the cloud and kill who or who ragequits first?” You know.

Then out come the cold hard facts and it all comes crashing down, dead stop. When was the last really good 2000+ ping thread you two started? I bet blam kills this one with some facts.

;-]

Ah, then what result did real science had when they tried to repeat the experiment?

Not much of a puzzle for a non-African species to die during a glaciation; mile high sheets of ice, no food.

LOL.

I think the 2000 post thread era is over and done.

I always liked Joe Friday years ago in Dragnet, "Just The Facts Ma'am"

Looks like the link above died. I'll try posting again:

The Genographic Project (Have Your DNA Checked, Find Your Roots)

BTW, I just submitted another sample for an expanded DNA test. These original tests were 12 marker tests and I'm upgrading to a 37 marker test at the request of my 'surname DNA project' group.

The info on the other thread was most likely in correct. Africans have no Neanderthal genes. Folks from Europe have the highest percentage.

No.. subsaharan Africans have no neanderthal at all...they are pure human. This is not true of the diaspora of Africans, who tend to be more mixed.

Kosmickitty: “The info on the other thread was most likely incorrect.
Africans have no Neanderthal genes.

I’ve read it both ways — Asians have more “Neanderthal DNA” , no, Europeans do.
But how many people know all 32 of their great great great grandparents?
Well, statistically speaking, one of them was a Neanderthal.
Which means, doncha know, that we all have as much “Neanderthal blood” as Elizabeth Warren has Native American blood.

And you just KNOW what that means?!
Yes! We are all official victims, **entitled** to special considerations AND compensation — yes reparations!

After all Neanderthals were obviously brutalized sexually, then coldly exterminated — so we can demand our RIGHTS!
Just like Elizabeth Warren...
But from whom?
Well, isn’t it obvious?
We Neanderthals deserve reparations from that portion of the human population which has no “Neanderthal blood”, right?

I mean, fair is fair, isn’t it?

;-)

Last I read, Asians have a slightly higher % of Neanderthal DNA than Europeans. Africans have none.

I thought Asians have vestiges of another neanderthal like species... denisovan? :)

C13 (the other stable isotope of carbon) comprises about 1% of organic carbon samples, and is the one compared with C14, which is much less than 1%.

Watching the video, he states he has over 5% C14 in a sample. That shows he’s not actually much of a scientist, and (like you) is just pounding the drum for his bias.

Ok lets stipulate for this discussion that the link is a fraud and everybody associated with it is dumber than a rock. Lets stipulate that I am dumber than a rock and no real scientist (which I am not, I be just a curious layman).

That out of the way (hopefully), what do real measurements of RC of dino bones show?

Dinosaur fossils don’t have an RC dating, because due to their age and composition, they exceed the limit of the method itself. The fact that the alleged physicist claims he found over 5 percent C14 in a sample — more than any organic form can have — shows he really doesn’t know what he’s doing, or what he’s talking about, AT BEST.

Still works for me, but anyway, here:

Tibetans have Denisovan-like DNA for altitude adaptation: New Study

July 4, 2014 4:14 pm

DHARAMSHALA: A new study conducted by a group of researchers at Beijing Genomics Institute (BGI) have concluded that Tibetans have a special gene, derived from an extinct human species known as Denisovan, which helps them adapt to high altitudes.

The study published by Nature, an international weekly science journal, identifies a long segment of DNA shared by the extinct people known as Denisovans and Tibetans.

In the new study, scientists collected blood samples from 40 Tibetans and sequenced more than 30,000 nucleotides on a segment of DNA containing EPAS1, the gene that makes Tibetans so well-suited for life at high altitude. Then the scientists compared that sequence with those of 1,000 individuals representing the 26 human populations in the Human Genome Diversity Panel. They found the high-altitude gene in only 2 of the 40 Han Chinese in the panel and no one else.

“Re-sequencing the region around EPAS1 in 40 Tibetan and 40 Han individuals, we find that this gene has a highly unusual haplotype structure that can only be convincingly explained by introgression of DNA from Denisovan or Denisovan-related individuals into humans. Scanning a larger set of worldwide populations, we find that the selected haplotype is only found in Denisovans and in Tibetans, and at very low frequency among Han Chinese,” the study said.

“Natural selection by itself could not explain that pattern,” said Rasmus Nielsen, a computational biologist at UC Berkeley and an author of the study. “The DNA sequence was too different from anything else we saw in other populations.”

“Genetically, Han Chinese and Tibetans are very similar throughout the genome,” Nielsen said. “But for this particular gene, they are extremely differentiated from each other, which is something you only see with very strong or very recent selection.”

The plateau of Tibet is one of the most hostile places people inhabit. The air is thin and the weather cold. The Tibetans, however, have thrived there for tens of thousands of years. This might be attributed to the special gene the Tibetans have inherited from the Denisovans, as a result of interbreeding between Denisovans and Neanderthals.

The Denisovans are a mysterious branch of Homo. They were identified in 2010 by an analysis of the DNA of a bone discovered in a cave (occupied in the 18th century by a hermit called Denis) in the Altai Mountains in Russia. This bone was thought, when found, to be either Neanderthal or modern human, but the analysis showed it was neither. In the wake of that finding, a small percentage of Denisovan DNA has been discovered in various groups of people in Asia and the Pacific islands, Tibetans among them.
