The Dinosaur Genome
“And God said, Let the earth bring forth the living creature after his kind, cattle, and creeping thing, and beast of the earth after his kind: and it was so.”
The BBC recently reported on its website that scientists from the University of Kent had mapped the genome of a dinosaur. The BBC’s article was not clear on which dinosaur but claimed it was a very early dinosaur – one of the precursors to all dinosaurs.
There was a great deal of excitement when scientists previously mapped the genomes of humans and chimpanzees. This led to the disingenuous and misleading claim that humans and chimps share 98% of their DNA.
But, given that there are no confirmed live dinosaurs in captivity, how was it possible for dinosaur DNA to be mapped? The BBC’s science correspondent reports:
Recently, Prof Darren Griffin’s team used mathematical techniques to identify the possible genetic characteristics of the very first dinosaurs. They did this by working backwards from their closest modern-day relatives – birds and turtles.
Did you spot the undefined false presuppositions in that quote? There is a strong presupposition that both birds and turtles are close relatives of early dinosaurs. However, this is a very big assumption and is not based on any reliable experimental data. Just in case you think this is simply the opinion of a science journalist, this is what the researchers said:
It is perhaps not an unreasonable speculation that both karyotypic and molecular cytogenetic analysis would reveal little difference from a modern chicken, duck or ostrich species.
It is precisely this speculation that creation science finds untenable. Instead of speculation, we build our models on the solid ground of biblical truth.
