    Interesting note: SFI-43 and SFI-44, according to authors, probably represent ancient Egyptian woman and her son. They dated to around 500 BC when both Egypt and Phoenicia were part of Persian Empire.

    Opa! That's an awesome finding-- thanks for the heads up!

    I still have to get through the other papers first!

    Well, I haven't started reading other papers yet, I started with Lebanese one.

    The women similar to Abusir el meleq mummies..her son 50% from her and 50% from mixed egyptian-levantinese father.
    She carried Mtdna T2c1a similar 3 other mummies as well.
    This find means the ancient dna from abusir was already representative of the egyptians at the time.

    This study, as opposed to Agranat-Tamir et al. 2020 ("The Genomic History of the Bronze Age Southern Levant") is full of astonishing news regarding the Levant.

    As I observed in the Roman Lebanese paper a year ago (Haber et al. 2019) - the new study from Lebanon verified both the additional Aegean admixture in the post-BA Levant, with several samples there as high as 20% Aegean (Mycenaean and Minoan), while then additional Eastern admixture during Persian and Hellenistic periods, and again during early Roman period more Southeast European (read - Hellenic):



    "Beirut_IA included individuals from the Iron Age II and Iron Age III periods and can be modeled as a mixture of the local Bronze Age population and a population related to ancient Anatolians or ancient South-Eastern Europeans."

    "We found that significant genetic changes that were marked by an increase in Eurasian ancestry related to ancient Europeans and ancient Central Asians occurred after the Bronze Age and starting from the Iron Age II (Figure S7A). We did not observe significant genetic differences between the Iron Age II and Iron Age III populations in this test (Figure S7), and thus, we merged our samples from these two periods into one population (Figure S7C) and used qpAdm (see Supplemental Methods) to explore possible Iron Age admixture models (Tables 2 and S7). We found that the Lebanese Iron Age population can be modeled as a mixture of the local Bronze Age population (63%–88%) and a population related to ancient Anatolians or ancient South-Eastern Europeans (12%–37%) (Table 2 and Figure 2.... showed that a Steppe-like ancestry, typically found in Europeans, appears in the Near East starting from the Iron Age II (Figure 2D). A potential source of this exogenous ancestry could be the Sea Peoples, a seafaring group of people with a disputed origin who attacked the Eastern Mediterranean and Egypt after the Bronze Age (1200–900 BCE). One of our successful models for admixture involved an ancestry source related to the Ashkelon (a city situated ∼170 miles south of the Beirut sites) Iron Age I population, which was previously identified as possibly descending from Sea-Peoples-related admixture."



    They also tested to see if this kind of Aegean-related ancestry penetrated Egypt, and concluded that:
    "...suggesting that either ancient Egypt did not receive the Eurasian gene flow that the Levant received during the Iron Age or that the Eurasian ancestry was replaced in Egypt as in Ashkelon, where in contrast to the Beirut_IAII, the European-related ancestry was no longer significant in the Ashkelon Iron Age II population."


    And finally:
    "Additional Iron Age samples from the Levant coast and Egypt could reveal whether the Iron Age admixture had a north to south cline as a result of the location of the source populations or from differences in the scale of the successful migrations to the north or south of the Levant during this period."

    So Haber et al. tied the persisting Aegean-ancestry to the Sea People. I have several issues with this:


    • First of all, as they stated in the beginning of the paper, none of the samples are older than 800 BCE, which means we're talking about Late IA II, rather than closer to the dates of ASH_IA I.
    • Second thing is, they only have two IA II samples, while the rest of the IA samples are from IA III, and as can be seen in Table 1 of the study, they are dated from the mid-6th century BCE to the early 4th century BCE - this is much too late for any additional Sea People to arrive.

    IMO, this additional Aegean admixture could be related to a similar movement we see in the Central Mediterranean and Anatolia, of Greeks settling and creating poleis, PRIOR to the Hellenistic era. This might sound far-fetched, but I believe that just as we completely underestimated the amount of Greek colonization and settlement in Italy prior to the ancient Roman paper (Antonio et al.) or Fernandez et al. which shown it might go back as far as the Late Helladic period, I believe we underestimated the amount of Greek presence in the Levant. For instance, there's the case of Al-Mina outpost in the Northern Levant which was a Eubean trading post and existed prior to the 8th century BCE. I believe the extensive cultural influence the Phoenicians had on the ancient Greeks (such as the myth of Europa, or Adonis, or the Phoenician alphabet etc.) also carried with it some historically, relatively obscure, gene-flow between the Levant and the Aegean isles, seen in the form of Levantine admixture in Greek islanders, but the other side of that equation was a Greek admixture in the Levant, perhaps only or mostly limited to the Phoenician Canaanite city states. This is especially obvious when we see maps of Phoenician maritime trade routes during the IA II and IA III based on known historical sources and archeological remnants:






    This Southeast European admixture, according to this study, also seem to have entered the Levant during the Roman-era:
    "When we model Qed_LRoman as a mixture of the Hellenestic/early Roman period population and another ancient population, we find successful models involving ancient Anatolians and South-Eastern Europeans"

    However, if that is the case, how come contemporary Lebanese do not plot as ASH_IA1 or further than they are from Sidon_BA?

    Well that's the other amazing part from this study - the substantial South Central Asian admixture which seem to have been added to the Levant during the Hellenistic period.

    It seems what "brought" back Roman-era Levantines (to be more Eastern shifted, so as to plot close to BA Canaanites) is additional South Central Asian admixture during late Persian and Hellenistic periods. I would assume that for Jews and Samaritans it's probably Babylonian admixture (from שבי ציון - returnees from Babylon) and Assyrian admixture respectively - or that the Southern Levant didn't see as much Aegean-admixture as Lebanon did during the Iron Age III period:
    "We found that the Hellenistic and early Roman population can be modeled as a mixture of the local population, Beirut_IA (88%–94%), and a Central/South Asian population (6%–12%)"

    So as can be seen, there seem to have been some sort of genetic pendulum at work here.
