I am seeking a solution to some of the controversies outlined on the Wikipedia page titled 'Origin of Romanians.' One potential avenue involves the utilization of historical DNA analysis on multiple sets of remains from Transylvania, showing close genetic kinship and spanning the period from the third century AD to the present. I will resolve the question using new information obtained from selective scientific studies, Wikipedia, news sources, and considering the probability and comments found on the pages. While I am of Romanian descent, I do not strongly align with any particular theory, and my aim is to maintain objectivity.
@Odoacre A recent study has demonstrated the possibility of extracting ancient DNA from specimens dating back 6000 years, yielding approximately 500,000 single nucleotide polymorphisms (SNPs). This number appears to be comparable to the quantity of SNPs used by 23andMe. Furthermore, the study was able to "estimate degrees of relatedness reliably up to the fourth to fifth degree".
I envision a scenario where the discovery of 10-20 individuals buried in Transylvania, spanning the Roman and early medieval periods, and showing genetic clustering with the present-day Romanian population, while being distinct from neighboring populations north of the Danube, could serve as compelling evidence for the enduring presence of Daco-Romans. Conversely, if no such genetic clustering is evident among the initial 10-20 samples, I would consider it sufficient evidence for later migrations.
