Can scientists turn a chicken into a dinosaur?
In other words, it is as if birds still have the molecular capability to grow teeth, but just aren't doing so anymore. Even though it hadn't been switched on in 150 million years, Chuong wanted to identify and reconnect that molecular pathway in order to re-active teeth-building processes.
By studying the genes, molecules and chemicals responsible for the growth of mouth and teeth structures in other organisms, Chuong was able to stir together a mix of molecules that might trigger the "dormant" circuitry into action. He then placed tiny beads of this concoction in the mouths of the chicken embryos. It worked. Through the microscope, he and his colleagues watched the embryos growing, as if the chickens had, all along, the genetic instructions to grow the beak. They may have had the ancient circuits to do so, but they needed just the right ingredients to be properly switched on.
Can your damn science do something worthwhile or not?
I don't want chickens with teeth, I want broiled T-Rex drizzled with reduction of Dodo. Or maybe extend the turducken concept out a few levels. Remember the big rack of ribs foretold by the Flintstones. You know, something useful.
If I didn't want to eat previously extinct animals, then I would have lived in the not-too-distant past.
