T rex Proteins

T. rex proteins found, according to reports in Science and BBC News 13 April 2007 . In 2005 Mary Schweitzer of North Carolina State University reported finding remnants of fibrous tissue and blood vessels in a Tyrannosaurus bone. There was some debate over whether this was really original organic material because, as Schweitzer commented to the BBC, "The pathways of cellular decay are well known for modern organisms. And extrapolations predict that all organics are going to be gone completely in 100,000 years, maximum." The T rex bone was believed to be 68 million years old. Schweitzer and a team of other scientists have now carried out more studies on the bone and found seven small fragments of collagen, a tough fibrous protein found in bones, ligaments and tendons.

Like all proteins collagen is made up of strings of amino acids, and the researchers worked out the amino acid sequence in the fragments. They then compared them with the amino acid sequence in collagen from living creatures. Two of the fragments matched sequences found in chickens; one matched frog collagen; one matched both chicken and frog; one matched newt, one matched newt, fish and mouse; and one matched "multiple organisms". Scientists claim these results confirm the theory that dinosaurs evolved from birds.

Editorial Comment: These results simply show that dinosaurs had their own kind of collagen, which has some sequences in common with other animals because it has to serve the same function. It is interesting that evolutionists are prepared to put uniformitarian principles aside when it suits them. If known decay rates for living tissue show that all organic matter should be gone in thousands of years, they should accept these findings as evidence that this dinosaur bone is not millions of years old if they truly believe the present is the key to the past, but then that would make evolution impossible as Dinosaurs could not evolve into birds in only 100,000 yrs.
