New open access paper Ancient DNA sheds light on the genetic origins of early Iron Age Philistines, by Feldman et al. Science Advances (2019) 5(7):eaax0061.
Interesting excerpts (modified for clarity, emphasis mine):
Here, we report genome-wide data from human remains excavated at the ancient seaport of Ashkelon, forming a genetic time series encompassing the Bronze to Iron Age transition. We find that all three Ashkelon populations derive most of their ancestry from the local Levantine gene pool. The early Iron Age population was distinct in its high genetic affinity to European-derived populations and in the high variation of that

An article published in PLoS ONE, Y-chromosomal analysis of Greek Cypriots reveals a primarily common pre-Ottoman paternal ancestry with Turkish Cypriots, by Alexandros Heraclides and colleagues, insists on the potential origin of R1b and R1a lineages in Greece from Indo-European migrations, albeit with strong regional (and thus most likely temporal) differences. From the article’s discussion:
Although the exact origins and migratory patterns of R1a and R1b are still under rigorous investigation, it seems that they are linked to Bronze Age migrations from the Western Eurasian Steppe and Eastern Europe into Southern (including Greece) and Western Europe. Apparently, such
