Okay, IF-it’s all right for scientists to be Shocked because red blood cells have been found in dinosaur bones supposedly millions of years old-then why is it wrong for creationists Not to be Shocked? Why can’t we say that this is what we might have expected-since, this is what we might have expected? Creationists will side with conventional scientific wisdom on this one–it’s not possible for red blood cells to survive for millions of years without being destroyed by the elements or becoming fossilized. Ms. Schweitzer get with the program!
Neatly dressed in blue Capri pants and a sleeveless top, long hair flowing over her bare shoulders, Mary Schweitzer sits at a microscope in a dim lab, her face lit only by a glowing computer screen showing a network of thin, branching vessels. ThatĂ˘â‚¬â„˘s right, blood vessels. From a dinosaur. Ă˘â‚¬Ĺ“Ho-ho-ho, I am excite-e-e-e-d,Ă˘â‚¬Âť she chuckles. Ă˘â‚¬Ĺ“I am, like, really excited.Ă˘â‚¬ÂťAfter 68 million years in the ground, a Tyrannosaurus rex found in Montana was dug up, its leg bone was broken in pieces, and fragments were dissolved in acid in SchweitzerĂ˘â‚¬â„˘s laboratory at North Carolina State University in Raleigh.
Ă˘â‚¬Ĺ“Cool beans,Ă˘â‚¬Âť she says, looking at the image on the screen.It was big news indeed last year when Schweitzer announced she had discovered blood vessels and structures that looked like whole cells inside that T. rex boneĂ˘â‚¬â€ťthe first observation of its kind.
The finding amazed colleagues, who had never imagined that even a trace of still-soft dinosaur tissue could survive. After all, as any textbook will tell you, when an animal dies, soft tissues such as blood vessels, muscle and skin decay and disappear over time, while hard tissues like bone may gradually acquire minerals from the environment and become fossils. Schweitzer, one of the first scientists to use the tools of modern cell biology to study dinosaurs, has upended the conventional wisdom by showing that some rock-hard fossils tens of millions of years old may have remnants of soft tissues hidden away in their interiors.
Ă˘â‚¬Ĺ“The reason it hasnĂ˘â‚¬â„˘t been discovered before is no right-thinking paleontologist would do what Mary did with her specimens. We donĂ˘â‚¬â„˘t go to all this effort to dig this stuff out of the ground to then destroy it in acid,Ă˘â‚¬Âť says dinosaur paleontologist Thomas Holtz Jr., of the University of Maryland. Ă˘â‚¬Ĺ“ItĂ˘â‚¬â„˘s great science.Ă˘â‚¬Âť The observations could shed new light on how dinosaurs evolved and how their muscles and blood vessels worked. And the new findings might help settle a long-running debate about whether dinosaurs were warmblooded, coldbloodedĂ˘â‚¬â€ťor both.
Meanwhile, SchweitzerĂ˘â‚¬â„˘s research has been hijacked by Ă˘â‚¬Ĺ“young earthĂ˘â‚¬Âť creationists, who insist that dinosaur soft tissue couldnĂ˘â‚¬â„˘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, itĂ˘â‚¬â„˘s not unusual for a paleontologist to differ with creationists.
But when creationists misrepresent SchweitzerĂ˘â‚¬â„˘s data, she takes it personally: she describes herself as Ă˘â‚¬Ĺ“a complete and total Christian.Ă˘â‚¬Âť On a shelf in her office is a plaque bearing an Old Testament verse: Ă˘â‚¬Ĺ“For I know the plans I have for you,Ă˘â‚¬Âť declares the Lord, Ă˘â‚¬Ĺ“plans to prosper you and not to harm you, plans to give you hope and a future.Ă˘â‚¬Âť
