Any modern replication? With all the replication crisis everywhere, and this research being extremely narrativistic, are there any modern experiments affirming these conclusions? It literally ran once and in the same environment, and only the last findings were taken? How do we know it's not just some specific genetic defect that propagated? Did they reintroduce new genes into the gene pool? Some other failure of the experiment? There wasn't even a control group in this entire thing, it's closer to a bedtime story than science. I'm extremely cautious about making broad assumptions with so little data.
