and the news that humans did come from monkeys but from ancient liberal humans has also astonished them.

Not a good week for evolutionists

EXCERPT :


No one would believe that dinosaur DNA would be preserved for 67 million years or more, and no one has found any. Similarly, no one would believe protein would be preserved for such a length of time, but Mary Schweitzer, a paleontologist at North Carolina State University, along with other colleagues found such protein and published this in 2007. Her team dissolved the mineral portion of a T. rex bone fragment of the same time period as Sue, and from the same Hell Creek Formation. They looked for any soft tissue residue. They found a residue that appeared to show a branching blood vessel, protein fragments and possible red blood cells.

....
....

Mary Schweitzer and a wide group of experts present evidence for proteins from an 80-million-year old hadrosaur, a duck-billed dinosaur. From excavation to biochemical analysis, the sample was handled in a way to preclude contamination. Demineralization was carried out independently in different labs; soft-tissue residue was sent to different labs for mass spectrometry studies. All concluded there was collagen present as well as two other proteins found in blood vessel walls. Subsequent studies showed the hadrosaur collagen to be more closely related to the T. rex collagen and to modern birds than to other species.

This raises the quite unexpected possibility of doing genetics, via proteins, on dinosaurs and on other ancient species as well. The backbone of a protein is made up of a chain of amino acids. The DNA of genes dictates the sequence of amino acids in the protein chain. Since the investigators were able to establish the amino acid sequences in the protein fragments they had, they should be able to infer the genetic code that specified each sequence. This is going back to the way genetic studies were done before we could study DNA directly - we simply looked at protein structural differences.

Great article! A real eye opener to the thought that the dinos were here just a short time ago...rather exciting if you ask me.

BTW, Many scientists argue that UNDER THE RIGHT CONDITIONS, DNA can survive a long time.

I know, with all the natural preservatives in nature, there’s no telling what we can find if we look in the right places. That is truly exciting that dinos could’ve been here such a short time ago. I firmly believe in the Creation by the Almighty God. Nothing I have read on Darwin has changed my mind in the least.

(How did Dinosaur soft tissue survive millions of years?)

Simple answer: it didn't. That stuff is a few thousand or a couple of tens of thousands of years old at most.

did you see the articles that evidence now shows monkeys evolved from liberal-splinter humans and not the other way around?

There have been perhaps a dozen, perhaps more, topics on this, and very few worth pingin’, unfortunately. Thanks FrogMom!

I think the dinosaurs are now with us, though some of them are dying even now:

Cheers!

LOL! Now that’s one breed that is becoming extinct!

Schweitzer didn’t produce the expected results so she must be wrong.

Could be. Some think the soft tissue could be from contamination.

That's what the methodology chart ( see Post #4 above ) seems to be saying.

That’s been thoroughly debunked. The tissue is definitely and obviously that of the dinosaur. No kind of contamination could produce blood vessels and hemoglobin inside of bones.
