Biologists recently found that feather colors and songs vary among some species within the South American genus Sporophila, also known as seedeater birds. But strangely, they did not find any genetic differences in the form of species-specific DNA markers. Do these variations fit any evolutionary pattern?

The researchers published their species comparisons in the Proceedings of the Royal Society B. In their report, they wrote, “Taken together, we suggest that this is a compelling example of an extremely rapid, recent and ongoing continental radiation, with species diverging in male plumage [feather] coloration patterns and song.”1

The terms “radiation” and “diverging” are routinely used to describe the supposedly slow and gradual Darwinian changes between animal kinds, like the radiation of dinosaurs that supposedly diverged into birds. The only divergence the researchers actually observed, however, occurred strictly within the seedeater bird population, which makes sense if the birds were created with the potential to fit and fill new environments.2

The study authors tried to explain why so many physical differences could be expressed without the expected underlying genetic differences. They suggested that the birds changed so fast and so recently that the genes have not yet had time to catch up.

But that’s like saying that a batch of cupcakes acquired sprinkles before its recipe had a chance to “catch up” with the cupcakes and specify sprinkles! Whether in the obvious written recipe or the less obvious recipe modifications in the mind of the baker, the end product is a result of prior planning.

These authors’ unscientific explanation seems to ignore the fact that trait differences are generated from within the organism. No external force in nature reaches into a bird’s egg, passes through the shell and yolk, and adds new feather colors or new brain cell connection patterns that would enable new bird songs….
