And even if you get the spill lit,E. as shown by the recent discovery of a third-century Roman battlefield in Harzhorn Germany And Arminius by no means united the more than 50 Germanic tribes of the time He persuaded five tribes to join him in battle but members of his own tribe soon killed him Moreover Arminius and his kin were not pure “Aryan” if that term means a person whose ancestors lived solely in what is now Germany or Scandinavia The Cherusci tribe like all Europeans of their day and later were themselves composites built from serial migrations into the heart of Europe and then repeatedly remixed “The whole concept of an ethnic German … it’s ludicrous when you look at the longue durée [long time] scale” says archaeologist Aren Maeir of Bar-Ilan University in Ramat Gan Israel After World War II many scholars recoiled from studying migrations in reaction to the Nazi misuse of history and archaeology The Nazis had invoked migrations of “foreign” groups to German territory to justify genocide “The whole field of migration studies was ideologically tainted” says archaeologist Kristian Kristiansen of the University of Gothenburg in Sweden Some researchers also resisted the idea that migration helped spread key innovations such as farming partly because that might imply that certain groups were superior Nor did researchers have a reliable method to trace prehistoric migrations “Most of the archaeological evidence for movement is based on artifacts but artifacts can be stolen or copied so they are not a real good proxy for actual human movement” says archaeologist Doug Price of the University of Wisconsin in Madison who tracks ancient migration by analyzing isotopes “When I started doing this in 1990 I thought people were very sedentary and didn’t move around much” Today however new methods yield more definitive evidence of migration sparking an explosion of studies The isotopes Price and others study are specific to local water and food and thus can reveal where people grew up and whether they later migrated DNA from ancient skeletons and living people offers the “gold standard” in proving who was related to whom The new data confirm that humans have always had wanderlust plus a yen to mix with all manner of strangers After the first Homo sapiens arose in Africa several bands walked out of the continent about 60000 years ago and into the arms of Neandertals and other archaic humans Today almost all humans outside Africa carry traces of archaic DNA Migrations through the ages Modern humans have been on the move ever since a small band of people migrated out of Africa more than 50000 years ago New studies of genes and isotopes are helping reveal how major migrations shaped who we are today (See slideshow below for artifacts that trace some of these ancient journeys) 60000 years ago 50000 40000 30000 20000 10000 5000 4000 3000 2000 1000 Today Ancient Aborigines The ancestors of today’s Aborigines migrate into Australia Out of Africa

first Europeans came from Africa via the Middle East and settled there about 43000 years ago But some of those pioneers such as a 40000-year-old individual from Romania have little connection to today’s Europeans Reich says His team studied DNA from 51 Europeans and Asians who lived 7000 to 45000 years ago They found that most of the DNA in living Europeans originated in three major migrations starting with hunter-gatherers who came from the Middle East as the glaciers retreated 19000 to 14000 years ago In a second migration about 9000 years ago farmers from northwestern Anatolia in what is now Greece and Turkey moved in That massive wave of farmers washed across the continent Ancient DNA records their arrival in Germany where they are linked with the Linear Pottery culture 6900 to 7500 years ago A 7000-year-old woman from Stuttgart Germany for example has the farmers’ genetic signatures setting her apart from eight hunter-gatherers who lived just 1000 years earlier in Luxembourg and Sweden Among people living today Sardinians retain the most DNA from those early farmers whose genes suggest that they had brown eyes and dark hair The farmers moved in family groups and stuck to themselves awhile before mixing with local hunter-gatherers according to a study in 2015 that used ancient DNA to calculate the ratio of men to women in the farming groups That’s a stark contrast to the third major migration which began about 5000 years ago when herders swept in from the steppe north of the Black Sea in what is now Russia Those Yamnaya pastoralists herded cattle and sheep and some rode newly domesticated horses says archaeologist David Anthony of Hartwick College in Oneonta New York In the journal Antiquity last month Kristiansen and paleogeneticist Eske Willerslev at the University of Copenhagen reported that the sex ratios of the earliest Yamnaya burials in central Europe suggest that the new arrivals were mostly men Arriving with few women those tall strangers were apparently eager to woo or abduct the local farmers’ daughters Not long after the Yamnaya invasion their skeletons were buried with those of women who had lived on farms as children according to the strontium and nitrogen isotopes in their bones says Price who analyzed them The unions between the Yamnaya and the descendants of Anatolian farmers catalyzed the creation of the famous Corded Ware culture known for its distinctive pottery impressed with cordlike patterns Kristiansen says According to DNA analysis those people may have inherited Yamnaya genes that made them taller; they may also have had a then-rare mutation that enabled them to digest lactose in milk which quickly spread It was a winning combination The Corded Ware people had many offspring who spread rapidly across Europe They were among the ancestors of the Bell Beaker culture of central Europe known by the vessels they used to drink wine according to a study by Kristiansen and Reich published this month “This big wave of Yamnaya migration washed all the way to the shores of Ireland” says population geneticist Dan Bradley of Trinity College in Dublin Bell Beaker pots and DNA appeared about 4000 years ago in burials on Rathlin Island off the coast of Northern Ireland his group reported this year This new picture means that the Hermann of lore was himself a composite of post–ice age hunter-gatherers Anatolian farmers and Yamnaya herders So are most other Europeans—including the ancient Romans whose empire Arminius fought The three-part European mixture varies across the continent with different ratios of each migration and trace amounts of other lineages But those quirks rarely match the tales people tell about their ancestry For example the Basques of northern Spain who have a distinct language have long thought themselves a people apart But last year population geneticist Mattias Jakobsson of Uppsala University in Sweden reported that the DNA of modern Basques is most like that of the ancient farmers who populated northern Spain before the Yamnaya migration In other words Basques are part of the usual European mix although they carry less Yamnaya DNA than other Europeans Farther north the Irish Book of Invasions written by an anonymous author in the 11th century recounts that the “Sons of Míl Espáine … after many wanderings in Scythia and Egypt” eventually reached Spain and Ireland creating a modern Irish people distinct from the British—and linked to the Spanish That telling resonates with a later yarn about ships from the Spanish Armada wrecked on the shores of Ireland and the Scottish Orkney Islands in 1588 Bradley says: “Good-looking dark-haired Spaniards washed ashore” and had children with Gaelic and Orkney Islands women creating a strain of Black Irish with dark hair eyes and skin Although it’s a great story Bradley says it “just didn’t happen” In two studies researchers have found only “a very small ancient Spanish contribution” to British and Irish DNA says human geneticist Walter Bodmer of the University of Oxford in the United Kingdom co-leader of a landmark 2015 study of British genetics The Irish also cherish another origin story of the Celtic roots they are said to share with the Scots and Welsh In the Celtic Revival of the 19th and 20th centuries writers such as William Butler Yeats drew from stories in the Book of Invasions and medieval texts Those writings described a migration of Gaels or groups of Celts from the mainland who clung to their identity in the face of later waves of Roman Germanic and Nordic peoples But try as they might researchers so far haven’t found anyone living or dead with a distinct Celtic genome The ancient Celts got their name from Greeks who used “Celt” as a label for barbarian outsiders—the diverse Celtic-speaking tribes who starting in the late Bronze Age occupied territory from Portugal to Turkey “It’s a hard question who the Celts are” says population geneticist Stephan Schiffels of the Max Planck Institute for the Science of Human History in Jena Germany Bodmer’s team traced the ancestry of 2039 people whose families have lived in the same parts of Scotland Northern Ireland and Wales since the 19th century These people form at least nine genetic and geographic clusters showing that after their ancestors arrived in those regions they put down roots and married their neighbors But the clusters themselves are of diverse origin with close ties to people now in Germany Belgium and France “‘Celtic’ is a cultural definition” Bodmer says “It has nothing to do with hordes of people coming from somewhere else and replacing people” English myths fare no better The Anglo-Saxon Chronicle recounts that in 449 CE, “Basically, “I was attracted to religion at a young age, studied close by and lived close to the synagogue.
