The study shows that through IBD sharing, which shows which groups share actual DNA with other groups (thus if there's actual recent genetic relationship), mainland Greeks and Albanians are relatives to each other, and not relatives to Greek islanders. Meanwhile, southern Italians, Greek islanders and Cypriots all IBD share with each other, which show they are related genetically.
Unfortunately, there aren't many possible other reasons for why this is the case, other than recent demographic events, which are highly likely as shown in scientific studies such as this one.
Now, you have people here denying reality, and coming up with conspiracies like they were shifted by Dorians much earlier. As I said before, Cretans and Dodecanese were both Dorian, and we don't have this high steppe admixture, and our major haplogroup is J2, not E-V13. So how do you explain those facts if the genetic shift occured earlier than Slavic invasion?
