Using DNA extracted from a finger bone found in Denisova Cave southern Siberia, we have sequenced the genome of an archaic hominin to about 1.9-fold coverage. This individual is group that shares common origin with Neanderthals. population was not involved putative gene flow Neanderthals into Eurasians; however, data suggest it contributed 4–6% its genetic material genomes present-day Melanesians. We designate this 'Denisovans' and may been widespread Asia during Late Pleistocene epoch. A...

Chemical analyses of ancient organics absorbed into pottery jars from the early Neolithic village Jiahu in Henan province China have revealed that a mixed fermented beverage rice, honey, and fruit (hawthorn and/or grape) was being produced as seventh millennium before Christ (B.C.). This prehistoric drink paved way for unique cereal beverages proto-historic second B.C., remarkably preserved liquids inside sealed bronze vessels Shang Western Zhou Dynasties. These findings provide direct...

New carbon and nitrogen stable isotope values for human remains dating to the mid-Upper Paleolithic in Europe indicate significant amounts of aquatic (fish, mollusks, and/or birds) foods some their diets. Most this evidence points exploitation inland freshwater resources particular. By contrast, European Neandertal collagen do not use but instead show that they obtained majority protein from terrestrial herbivores. In agreement with recent zooarcheological analyses, results shifts toward a...

We report here on the direct isotopic evidence for Neanderthal and early modern human diets in Europe. Isotopic methods indicate sources of dietary protein over many years life, show that Neanderthals had a similar diet through time (approximately 120,000 to approximately 37,000 cal BP) different regions The indicates all cases were top-level carnivores obtained all, or most, their from large herbivores. In contrast, humans 40,000 27,000 exhibited wider range values, number individuals...

Selected as the Sunday Times History Book of Year for 2012, this is a meticulous work scholarship from foremost historian 20th-century Spain. The culmination more than decade research, 'The Spanish Holocaust' seeks to reflect intense horrors visited upon Spain during its ferocious civil war, consequences which still reverberate bitterly today. brutal, murderous persecution Spaniards between 1936 and 1945 truth that should have been told long ago. Paul Preston here offers first comprehensive...

Modern humans replaced Neandertals ∼40,000 y ago. Close to the time of replacement, show behaviors similar those modern arriving into Europe, including use specialized bone tools, body ornaments, and small blades. It is highly debated whether these developed before or as a result contact with humans.

The transition from the Middle Paleolithic (MP) to Upper (UP) is marked by replacement of late Neandertals modern humans in Europe between 50,000 and 40,000 y ago. Châtelperronian (CP) artifact assemblages found central France northern Spain date this time period. So far, it only such assemblage type that has yielded Neandertal remains directly associated with UP style artifacts. CP also include body ornaments, otherwise virtually unknown world. However, been argued instead being...

We compare two methods of isolating bone collagen for stable carbon and nitrogen isotope analysis.

Archeological analysis of faunal remains and lithic bone tools has suggested that hunting medium to large mammals was a major element Neanderthal subsistence. Plant foods are almost invisible in the archeological record, it is impossible estimate accurately their dietary importance. However, stable isotope (δ 13 C δ 15 N) mammal collagen provides direct measure diet been applied two Neanderthals various species from Vindija Cave, Croatia. The evidence overwhelmingly points behaving as...

Abstract We report on the measurements of carbon and nitrogen stable isotopes both bone teeth from a single site population (Medieval Wharram Percy), undertaken to explore variations due weaning in past population. There have been number recent studies using δ 15 N values ribs, we indicate assumptions that must be met before results such can correctly interpreted. found rib collagen decrease adult levels after age 2 years, indicating occurred at or this age.

Sulphur isotope measurements of bone collagen from archaeological sites are beginning to be applied more often, yet there no clear criteria assess the quality and therefore validity sulphur values. We provide elemental data different methods (DNA sequences, amino acid sequences mass spectrometric measurements) which used establish a reliable system for analyses collagen. The difference in amount fish mammalian type I led suggestion use vivo character between these two categories. For...

Abstract We present here the results of a large‐scale diachronic palaeodietary (carbon and nitrogen isotopic measurements bone collagen) study humans animals from single site, city York (U.K.), dating Roman period to early 19th century. The human sample comprises 313 burials cemeteries Trentholme Drive Blossom Street (Roman), Belle Vue House (Anglo‐Saxon), Fishergate (High Later Medieval), All Saints, Pavement (Later Post‐Medieval). In addition, 145 samples mammal, fish bird sites Tanner Row...
