INTACT DINOSAUR GENOME?
How have you all been this past week in our transitional time of weather patterns. Here in the northern hemisphere autumn is setting in with all its beautiful colors and promise of relief from the hot summer weather. It is my favorite time of year!
Speaking of transitions, I recently read an interesting article on dinosaur genomes. But what, you may ask, is a genome? It is the total amount of genetic information in the
chromosomes of an organism, including its genes and DNA sequences. It is the complete set of DNA and contains all the information needed to build and maintain an individual. A little over a year ago the University of Kent, in Kent Ohio, announced they had pieced together a segment of dinosaur genome. How stunning! But is it true?
The scientists research involved attempting “…to deduce the genome of a precursor to the dinosaurs…Using this deduced genome, the researchers then worked forward, tracing the changes in chromosomes up the evolutionary tree of life.
The scientists continued tracing until they reached birds, which they considered as either living dinosaurs or the descendants of dinosaurs.”1 The researchers believed that if they could make metaphase chromosomes of theropods, the genome would be virtually the same as a modern chicken, duck, ostrich or even a spiny soft shelled turtle. In other words, what they are saying is, if the DNA of a velociraptor and modern chicken were viewed under a microscope they would be similar. They called this bold claim a reasonable speculation.
“The researchers used the chicken genome as its primary source, although they used other sources including reptilian and mammalian variants. The chicken was chosen as the basis because its genome had purportedly changed the least from its reptilian ancestors. No dinosaur genome has ever been observed simply because no dinosaurs are currently
alive. Because DNA is very unstable outside the body and degrades rapidly, it is unlikely that such a genome will be sequenced in the foreseeable future. Thus, the researchers had to assume that the chicken had changed the least from its presumed ancestors. (Keep in mind that they had no hard evidence that this was the case.) They then took that assumption and used it to build a genome for a hypothetical dinosaur ancestor. It should come as no surprise that the genome they deduced resembled modern birds; after all, they used several bird genomes as part of the basis for the study.”2

Just like the famous Urey-Miller life from non-life experiment, these researchers started with the wrong
ingredients. And just as neither Urey or Miller would ever admit that their experiment was a flop, these scientists will continue to try to make Dino genomes.
Dr. Richard Lewontin, a noted evolutionist, states, “‘…no matter how counter-intuitive, no matter how mystifying to the uninitiated…we cannot allow a Divine Foot in the door.’ Dr. Lewontin is admitting here that many evolutionists will always look for a materialistic explanation, regardless of evidence. This explains why the authors of the aforementioned study make such flawed assumptions.”3
Until next time, take care and God bless,
