Ancient human movements through Asia DNA has allowed us to begin tracing the history of across globe. Narasimhan et al. identify a complex pattern migrations and admixture events in South Central by performing genetic analysis more than 500 people who lived over past 8000 years (see Perspective Schaefer Shapiro). They establish key phases population prehistory Eurasia, including spread farming peoples from Near East, with both westward eastward. The known as Yamnaya Bronze Age also moved...
Maya and Climate has affected the vitality of many different societies in past, as shown by numerous records across globe throughout human history. One most obvious spectacular examples this is from Classic civilization, whose advanced culture left highly detailed all aspects their existence between 300 1000 C.E. Kennett et al. (p. 788 ; see cover) present a climate record derived stalagmite collected cave Belize, midst settlement. The fine resolution precise dating allows changes...
Genomics of the Iberian Peninsula Ancient DNA studies have begun to help us understand genetic history and movements people across globe. Focusing on Peninsula, Olalde et al. report genome-wide data from 271 ancient individuals Iberia (see Perspective by Vander Linden). The findings provide a comprehensive time transect region. Linguistics analysis archaeological human remains dating about 7000 years ago present elucidate impact prehistoric historic migrations Europe North Africa. Science ,...
Highlights•Genome-wide analysis of 49 Central and South Americans up to ∼11,000 years old•Two previously unknown genetic exchanges between North America•Distinct link a Clovis culture-associated genome the oldest Americans•Continent-wide replacement Clovis-associated ancestry beginning at least 9,000 agoSummaryWe report genome-wide ancient DNA from individuals forming four parallel time transects in Belize, Brazil, Andes, Southern Cone, each dating ∼9,000 ago. The common ancestral population...
Three archaeological sites on California's Channel Islands show that Paleoindians relied heavily marine resources. The Paleocoastal sites, dated between ~12,200 and 11,200 years ago, contain numerous stemmed projectile points crescents associated with a variety of aquatic faunal remains. At site CA-SRI-512 Santa Rosa Island, peoples used such tools to capture geese, cormorants, other birds, along mammals finfish. Cardwell Bluffs San Miguel collected local chert cobbles, worked them into...
Abstract For societies with writing systems, hereditary leadership is documented as one of the hallmarks early political complexity and governance. In contrast, it unknown whether succession played a role in formation prehistoric complex that lacked writing. Here we use an archaeogenomic approach to identify elite matriline persisted between 800 1130 CE Chaco Canyon, centre expansive society Southwestern United States. We show nine individuals buried crypt at Pueblo Bonito, largest structure...
Because of differences in craniofacial morphology and dentition between the earliest American skeletons modern Native Americans, separate origins have been postulated for them, despite genetic evidence to contrary. We describe a near-complete human skeleton with an intact cranium preserved DNA found extinct fauna submerged cave on Mexico's Yucatan Peninsula. This dates 13,000 12,000 calendar years ago has Paleoamerican characteristics Beringian-derived mitochondrial (mtDNA) haplogroup (D1)....
Abstract Multiple lines of genetic and archaeological evidence suggest that there were major demographic changes in the terminal Late Pleistocene epoch early Holocene sub-Saharan Africa 1–4 . Inferences about this period are challenging to make because shifts past 5,000 years have obscured structures more ancient populations 3,5 Here we present genome-wide DNA data for six individuals from eastern south-central spanning approximately 18,000 (doubling time depth African DNA), increase quality...
By sequencing 727 ancient individuals from the Southern Arc (Anatolia and its neighbors in Southeastern Europe West Asia) over 10,000 years, we contextualize Chalcolithic period Bronze Age (about 5000 to 1000 BCE), when extensive gene flow entangled it with Eurasian steppe. Two streams of migration transmitted Caucasus Anatolian/Levantine ancestry northward, Yamnaya pastoralists, formed on steppe, then spread southward into Balkans across Armenia, where they left numerous patrilineal...
Relict woolly mammoth (Mammuthus primigenius) populations survived on several small Beringian islands for thousands of years after mainland went extinct. Here we present multiproxy paleoenvironmental records to investigate the timing, causes, and consequences disappearance from St. Paul Island, Alaska. Five independent indicators extinction show that mammoths until 5,600 ± 100 y ago. Vegetation composition remained stable during window, there is no evidence human presence island before 1787...
East African genetics and pastoralism The origin spread of domestic animals across the globe also affected underlying genetic composition human populations. In Africa, however, it has been difficult to identify impact interactions among migrating food producers local hunter-gatherers. Prendergast et al. wanted discern timing movement husbandry its effects on foraging communities in Africa. They sequenced 41 ancient eastern genomes from individuals that lived approximately 100 4000 years ago....
There are many unanswered questions about the population history of Central and South Andes, particularly regarding impact large-scale societies, such as Moche, Wari, Tiwanaku, Inca. We assembled genome-wide data on 89 individuals dating from ∼9,000-500 years ago (BP), with a particular focus period rise fall state societies. Today's genetic structure began to develop by 5,800 BP, followed bi-directional gene flow between North Highlands, Highlands Coast. detect minimal admixture among...
We use carbon isotopes in human bone as the earliest direct evidence for maize a staple grain Americas.
The Younger Dryas impact hypothesis posits that a cosmic across much of the Northern Hemisphere deposited boundary (YDB) layer, containing peak abundances in variable assemblage proxies, including magnetic and glassy impact-related spherules, high-temperature minerals melt glass, nanodiamonds, carbon aciniform carbon, platinum, osmium. Bayesian chronological modeling was applied to 354 dates from 23 stratigraphic sections 12 countries on four continents establish modeled YDB age range for...
Significance New accelerator mass spectrometer (AMS) 14 C dates of scarlet macaw ( Ara macao ) skeletons from Chaco Canyon in northwestern Mexico reveal the earliest (A.D. 900–975) direct evidence for procurement this Neotropical species by Pueblo people Mesoamerica. By directly dating macaws, we demonstrate existence long-distance acquisition networks throughout much 900–1150) Chaco’s history. In contrast to models societal evolution that attribute macaws 11 th -century peak Chacoan...
Abstract During the Early Bronze Age, populations of western Eurasian steppe expanded across an immense area northern Eurasia. Combined archaeological and genetic evidence supports widespread Age population movements out Pontic–Caspian that resulted in gene flow vast distances, linking Yamnaya pastoralists Scandinavia with pastoral (known as Afanasievo) far to east Altai Mountains 1,2 Mongolia 3 . Although some models hold this expansion was outcome a newly mobile economy characterized by...
