"Scientists at the University of Chicago have created the first genetically modified animals containing reconstructed ancient genes, which they used to test the evolutionary effects of genetic changes that happened in the deep past on the animals' biology and fitness."
"We found that the accepted wisdom about the molecular causes of the flies' evolution is simply wrong."

Sounds like they will be testing more cases in the future:
"Nevertheless, because of technical and conceptual advances, it should now be possible to experimentally assess the causal predictions of many previously untested or weakly tested hypotheses of historical molecular adaptation, allowing them to be corroborated or, like the classic hypothesis of ADH divergence in D. melanogaster, decisively refuted."
