Italians got more DNA From High Classes Romans(Italian IA Drift into Late Antiquity Italians)

 Italians Are Descendant from High Classes Romans

  It is a little bit difficult to Understand how population came from 2000 years ago to today, some people cant understand how  Natural Selection played a brutal role in how our genome were made. Some people cant simple understand how the selection still acting in our societies, regardless of how sophisticate we are and how our medicine could advance. Off course, medical resources, better sanitary conditions, antibiotics could really help the last comfortable classes in our Societies, but it wasn't the case in most of our History. Moments of several population decreasing seen to be connected with high taxes of Natural Selection and it was the case in Late Roman Empire Era. 

  First let's talk about Roman Society in the Golden Ages of Empire, the Giulio-Claudian dynasty until the reign of Dominican, sudden i will explain how can we prove it with genetics and latter we will came to one obvious conclusion. Roman society was a Slave-Based society, made up with around 25-30% Slaves, mostly took from Conquests upon all the Mediterranean World. They were, since the End of Punic Wars and Gracchian Reforms times the highest part of Rural Lands inhabitants, since the Higher Classes took over the control upon the Land of Plebeians , causing massive Rural Exodus and placing massive amounts of Slaves from Carthage in their farm settlements, and it was improved upon the Imperial Era, with massive levels of Slaves came from Gallia, Eastern Mediterranean areas(the most populated before Roman Imperial Times), Greeks, Balkanic, etc.. Roma have even imported massive amounts since the Slave's Fertility rate was considerable low as we compare with Commoners and Upper classes. 

  Secondary they had Free-Born Man with Plebeians, or Proletarians, status, they were initally from Non-Latini families that placed themselves in Rome and Secondary from  Ever Part of Empire. The highest part of Imperial Roman Population came from Eastern Mediterranean provinces, mostly Anatolia, after the conquest that General Pompeu Magnus took against Hellenistic Alexander's Successors Empires, we could confirm it with history and genetics, we saw that Imperial Roman Era had increased DNA from East_Mediterranean Anatolian, Hellenistic Like, those who were Mixed Between Hellenics, Anatolians, Levantines, Mesopotamians and Iranians,and it was the highest populated territory in the Hellenistic Near Eastern's Times. Not a single migrant, but above the highest portion of Roman Population during Imperial Time was almost 70% Derived from Eastern Mediterraneans, if fewer individuals reassemble those who had founded the Republic and Made the Empire. Plebeians were 50-60% of Roman Population , some got high status, by economic measures, and could easily ascendant to Senatorial Cast, but it was a minority that doesn't have any chance to resemble the majority of Elites in Rome.

  Third Population  was the Elites, made up with Patricians, Equestrians and those who had came from Migration and got very rich in the Italian Peninsula, probably by Commercial Success. We could estimate that they ranged around 12% of Roman Population and had more contribution from Ancient Italic Tribes, since they were the descendants of Roman Foundators and still have some trouble on Mixing with those who hadn't their origins in Italic, Etruscan or Hellenic heritage. We saw several individuals in Imperial Era, buried in more noble locations, that were almost identical from those in Republic Times, reaching 60-70% Italic or Etruscan DNA and 30-40% Hellenic origin, considering Patricians, and lower levels of Italic and some from Levantine, Iran or Mesopotamia, who we can presume that were Equestrians. Those resemble in highest degree the Dominus of Society. 

  In that time Farmlands were almost exclusively property of those in High Ranks, we saw it by Several Studies that secure more than 50% Urbanization in Imperial Era, considering Italy Itself. Empire had 30% Citizens but Italy had 55% by some sources. Almost all Plebeians lived in Cities and Farmlands were related to Slaves, some of them had substantial ancestry in North Africans Carthaginians, we saw it inclusively in Burial Practices and Material Culture, not only by DNA. It was really incredible that those slaves still caring North African Genome after 200-300 years of Carthaginian's Wars, seems that historical sources, from Late Imperial Era, were accurate considering those from Farms were even more East Med and South Med than the Plebeians in City Itself.  

Population of Roman Cities upon 117 AD, source "Hanson et al.2019"

  Some say that it was bullshit, meaning that historical sources weren't important and we have to just  consider genetics, so i invite you to look upon  De Angelis et al., 2021 , an research made with several individuals that came from Roman Rural Areas during Imperial Times. Keep a closer look and sudden you will understand why we couldn't consider, by genetics, any argument that provides Farmlands Genetic's Makeup,  we saw that those in Farmlands were totally different from those that lived in Cities, they cant resemble even the East Med Anatolian Like that we saw in Cities, comparative with modern Italians they didn't give any substantial ancestry from those that live in Italy today, and if some got might been from Arabian or Punic Colonization, like we saw on Malta and Spain(Higher than Italy).

                                                   So we could seen the opinion of those who made the article:

 "Archaeological evidence could be consistent with at leasta cultural impact of Northern African people on the individuals buried in QCP. Indeed, several personal goods recovered in the necropolis and funeral architectures seem to wire thesouthern shores of the Mediterranean Sea to QCP.Remarkably, several cupae tombs were in the graveyard.These peculiar barrel-like structures were widespread acrossthe Mediterranean between the 1st and 3rd centuries AD for the middle social class comprising liberti, and soldiers and their families (Baratta 2018). 

These architectures showed up in the Africa Proconsularis,Numidia, and Mauretania (the pre-sent-day northern African coastal belt comprising Morocco,Tunisia, Algeria, and Libya), and spreading to the Lusitania(the current Portugal), towards the Betica (Andalusia) and theHispania Citerior (present-day Catalunia) up to Sardinia(Baratta 2009).

 The genomic legacy of people from QCP with the inhabi-tants of the South-Eastern shores of the Mediterranean Seaand the Central and Western Northern-African funerary influ-ence pave the way for considering the people buried in QCPresembling a Punic-derived human group. The recovery ofminiaturised pottery items in the tombs (Musco et al. 2001)is also consistent with the Phoenician and Punic rituals pro-viding these items to prematurely dead children(Nitschke 2015)."

   As we saw not a single evidence of Rural Genetic similarity between those that were seen in Late Antiquity Rome and those we founded in Rural Areas of Rome, except, of Course, from some outliers found on other cities, more in the interior of the peninsula. If we find more details we could saw others Documented Sources that may explain what happened from this Slave-Related Population and why we wont expect some mysterious Rural DNA that come to Rome and Brought the Averages from what we saw in Late Antiquity. 

  Some may think that it was a phenomenon restricted to Central and South Italy, but in realty we didn't have any source for saying those absurdist toughs . Like we saw in several researches since the 2th Centuries Rural Areas were massively Latifundi in whole Italic Peninsula, several researchers took a close look upon this tematic and founded that Roman. Dr. Petterson said in "Rural LandScape of Italy" (https://doi.org/10.1093/acprof:oso/9780198140887.003.0002) that around all Rural Settlements in Italy were under the Patrician, Equestrian and High Ranks Plebeians direct control until the 5th Centuries. The Latifundi was the dominant model and around all the population founded in Rural Zones were Slaves. This opinion was seen not on Petterson's Viewing instead they were the Academical Consensus, as we see on several researches, including north Italy such as "Hélène Verreyke and Frank Vermeulen 2009"(https://www.jstor.org/stable/20627545), proving the fallacy of Farm Attribution from the New Genetic Make Up of Italian Peninsula. Some researches made this proposition for Thracian and Moesian individuals, but extrapolating it for All Over the Empire seeing to been a Absurdist View from those that had never redden one single paper upon Roman's History. We also could seen that Rural Population was massively increased during Late Imperial era by "C. R. Whittaker  and Peter Garnsey 2008" with the Arrival of the new Coloni to the Farmlands. So what could explain such massively genetic drift that we seen in Italians after Late Imperial Times? We should return into Historical References and after we could explain the genetic distinction.

  First lets keep in mind that those Imperial Romans weren't homogeneous and those Found in Rural Settlements, even in Toscania and Marche weren't closer to Modern Day Italians. All over the Italian Penisula was massively changed during Imperial Times, by Massive Migration from Eastern Provinces to West, and we saw a increased in all Western Provinces Populations, those whom carried east med genetics and changed all the Imperial Genetic Make Up. We saw those individuals in Iberia, including West Iberia, in France, North Italy, Sardinia, Italy itself, balkans, etc... some may argue that Balkanic Roman Elites were almost Hellenistic Like, and i secure you that Elites on Eastern Half of Roman Empire might been from Hellenistic origins, since we have bunch of arguments that proved the Hellenistic impact in administration of East, even centuries before Romans. So we shouldn't expect an Italic Genetic Drift seen in Balkan Roman's Elites, since they weren't Latin-Derived but Graeco_Anatolian. Considering it we might expect a higher degree of East Mediterranization in Modern Day Western European Countries but even if we saw some remarkable genetical contribution it wasn't proportional from their impacts in the genetic's saw on Imperial Times, since they composed a massive number from those we consider "Romans" in ever single province of Western Roman Empire but their contribution was lower than the proportional amount we should expect. 

  Considering it, we SHALL assume that those individuals weren't proportionally related to the modern days Romance Speakers than they were at the same place in Imperial Times, not only by repopulation and later invasions, but cause most of them didn't contribute to the Ancestry from those we call Romances today, specially when we talk about Italy where those whom we referred were the huge amount of Population during Imperial Era. We consider 14 Millions inhabitants on Italy upon the 1-2th Centuries and Most of Them(60-70%) didn't have a substantial ancestry on Italic Iron Age, remarkable those from Plebeian's Suburbans zones and Rural , such as Lazio Rural, Casa Novalle and Marche. None of them resemble Late Antiquity, being at least 80% Greek+Near East_Middle Eastern, with lower or, mostly, NONE Italic IA ancestry. 

  Most should tough misconceptions upon Roman Decline and what causes it, mostly assume that Germanic simple took over the peninsula and got end from that prosperity and high advanced Italy. But they were absolutely wrong. Rome's Decline started in 2th Centuries when Antontine's Plague took over around 30% of Roman Population , mostly from those that had worst sanitary conditions and food-access, as you should assume that immunological system was really worst in those who didn't have good economical conditions. Mostly died in Cities, so we could assume that slaves weren't kill until 3th centuries. When it started we saw another Plague, Cyprian, that initially took over 10-60% of Roman's Population and later was succeeded by a Massive Political Crises, which we refer at 3th Centuries Crises,which leads roman slave population to suddenly decreased. Those crises consisted into the Broken of Commercial System, several Civilian Wars, famine, impoverishment and depopulation as we never seen in Western World Before. This crises succeeded the Antontines and Cyprian Plagues adding the Weather Conditions, that leads agricultural to simply broke up, causing massive famine, which united with lower Fertility rates seeing in Slaves and Plebeians caused massive deaths in Roman Society. 

  If we consider pre crises time roman society was almost composed by Non-Productive Civilizans and Slaves, almost all Population, either we exclude Child and Women, were composed by Non-Productive individuals that survived mostly from Clientela and State Welfare. Only 15-25% of Free Adult Male individuals could been consider productive, adding those 30% Slaves. Excluding crises situations it might been considering something really comfortable to those whom we call "Commoners". By the beginning of 2th Centuries, with Huge Amount of Deaths, related to plagues, and Agricultural Crises, leading to more and more deaths, causing the decrease of Slave Population and massive depopulation of Farm Lands, we could assume that around 50-60% Population living in 1-2th Centuries and their descendants weren't Alive or Either Passed their lineages for a huge amount of the Survival Population. That tulmutual context leaded to the Commercial's System Broken, Civilian Wars, Militarization and Improvishment, with several Elites and Comfortable commoners even migrating into Rural Areas for Practicing the Colonati labor, what current historical sources seen as the beginning of Serfdom, but we should been cautious considering that wasn't the Final context and later historical events caused even more changes in Italian Economic Structure. 

  Sudden, those new Coloni, who were treaty as similar as Serfs , weren't from Slave Derived, since we saw in several articles, such as , they often came from High Ranks who got poorer by their lands became less profitable and they slaves died. Also we should expect that the High Fertility rates seeing in Elites Females, with higher chance of Surviving until the Reproduction's Ages , we assure that some of them wouldn't take much of their families possessions, also it might decrease the family's influence, by all meaning concentrate of Resources should leads to better chance of Surviving. Also it doesnt mean that those from Lower Class Level and even Slaves didn't contribute to 4th Centuries heritage of Italians, but they might been lower that we could assume by their representation in the Population's Demography at the 1-2th Centuries.

  It wasn't the End, when the 4th Centuries Began, they had more political issues , more civilian wars, more barbarian raiders, the Chaotic Situation leads Italy to even more population decline,and we might expect more Lower Classes in those who deaths than whom presumably had more conditions to survive and pass their descendant above. It was huge enough to made the Christian Religion the highest among population, imagining how that Apocalyptic Scenario should leads to  conversions from those who feared that their gods had abandon them. After Imperial Separation and one Later Civilian War, Constatinous took the power in all over the Empire and start to Accept the Christian Religion, ending the christian persecution and open doors to Christian Domination. Also he took Constantinopla as his New Capital and got a high amount of Roman Bureaucracy for his New's Rome, leading a New Massively depopulation in Rome City. We should assume that those who came with him had Christian Faith, if we remember that Greece was even more Christian than Rome, deeply involved into the Born of Christian Religion. Several Patricians weren't comfortable with the Religion Swift and still practicing their religion, most of them even refused to adopted it when Theodosus took it the official state religion. By all means they were persecuted and most got exiled in Rural Areas, seeking to conserve their gods and negleting those they consider Heretical. 

  New Civilian Wars were fought in Italy and Late Western Roman Empire leading to continuous massive depopulation. The eastern provinces, now at the Eastern Roman Empire, should been prosperous, regarding all the Imperial Prestigious, as the Western Throne was settle by Usurpers and Authoritarians. Germanic incursions were always a trouble, but got higher since Rome didn't have money to spend in such campaigns, causing more and more panic and Chaos. The End of Western Roman caused by Germanic Invasions was simple the last step, although that may been significant for Changing the Society, causing even more deaths, migrations, impoverishment, changes in Social Structure and destruction of infrastructure. We started with Vandalic Raids and Odoacer's Rule, in the 5th Centuries, looking at how those events literally destructed what survived of Roman's Society. Italians, with Roman Origins, went to the fortify cities expecting to survive. Such changed brought Roman Population to decline from 1-2 Million(1-2th century) to 100 Thousands(5th centuries), even moving the capital from Rome to Milan, expecting to protect the city against invasion. It proved failed when Odoacer's Goths took all the Peninsula as easy as they came into Pó's Valley, either his Ruler wont during for a long time, being replaced by Theodoricus, with Byzantine Support. Both those were Christian and Stilled themselves as "Western Roman Emperors", being more favorable to Roman Population, either tooking their lands, 1/3 at Least, for their own warriors, causing more impoverishment in Senatorial Class. Population decrease even more, being lower and lower even the fertility rates stilled high, specially in those that came from High Ranks.

  As we saw in historical Sources the Genetic Makeup of Italy Itself got lower which century we saw, and such sort of populational decreasing could been related as Darwinism Law added to Artificial Selection, since we should assume that it was a selection not only based on Genetic Quality but Conditions Access. Thus lets compare the Genetical Make Up of Several Italian Cities from Imperial to Late Antiquity and Later we could check if we can check it by genetical markers. 

First , let's look upon Research after amateur g25 models. Lets see upon  " Antonio ML, Gao Z, Moots HM, et al.2020 Ancient Rome: A genetic crossroads of Europe and the Mediterranean. Science."

 

 

 

 

 The three sites represents one population from Eastern Mediterranean proxy found into a Merchant Port, called Isola Sacra, and thus could been a good source for East Mediterranean Settlers, almost from Hellenistic Heritage. Second was Late Antiquity Crypta Balbi, related from those

In late antiquity we could saw Roman Averages came to those that we saw in Modern Days, clustering with Thracians and Illyrians like modern days Italians, meaning the admixture between those with Republican Italian like heritage and some from minority from Near East.

 The lack of Samples clustering with Italic IA on those Imperial Era related might been explained by the Practice of Cremation from those who called elites. That variation upon burial practicing x social class should explain why we lack R-U152  on those Imperial Era Romans, even if we saw several R-U152 lineages found on Iron Age and Republican Italians. R-U152 was the lineage related to Proto-Italics, Urnfield Like Proto-Villanovans, even it could been found on Pre-Italic societies, such as Etruscans and Euganoi, either their lineages usually resamble R-Z36 variations that can't be related to Central European lineages since 2th Milenium B.C , in contrast from those we saw on Italics, related between 1000-1400 BC(estimations by TMRCA YFULL, T.M.R.C.A meaning Time of Most Recent Common Ancestral or Last Recent Common Ancestor, reffering as the Ancestor clade of some lineage, meaning a variation around 500-1000 years that the Last Ancestor from some lineage could existed). 

  Now lets take a look upon the Demographical Changes placed on Roman Demographics and the Migrations Patterns from outsiders that leads to Changes on Social Structure and than collapse
