‘Landmark study’ solves mystery behind classic evolution storyReally? So 5% of the dark moths do NOT have the mutation? And no one knows what that mutation actually does? So the mystery is "solved"? This is more bogus conclusions from what should be dispassionate science. They have NOT conclusively proved anything, because the data shows otherwise.
"The scientists found a single genetic variation in 95% of the dark moths that was missing in every pale moth they tested, they report online today in Nature. The mutation—the insertion of a portion of DNA that can “jump” to a new location within a genome—occurs within cortex, a gene known to affect cell division and egg development in fruit flies. “It’s surprising that it’s this gene, rather than something that’s more recognizably wing pattern–related or color pattern–related,” Saccheri says."
"Considering the differences between moths and butterflies—they’ve been following separate evolutionary pathways for about 100 million years—the fact that the same gene plays an important role in the wing coloration of both groups is an intriguing result, Holland says. He adds that the next step will be to find the mechanism by which cortex works. This latest addition to the peppered moth tale, he says, “is going to be in the textbooks for decades to come.”Yes. I'm sure that it will be enthusiastically added despite not being the case.
